Geratomran Reconquest



The Geratomran Reconquest was but one of a series of brushfire wars the Imperium of Man fought in the wake of the Macharian Crusade. With the great crusade of Lord Commander Solar Macharius drawing in the military resources of virtually all the Segmentum Pacificus and half the Segmentum Tempestus, several worlds turned from the Emperor's light. One was the Industrial World of Geratomro, which entered a state of open rebellion after being unable to meet the required Imperial Tithe fixed by the Adeptus Administratum.

Faced with the resistance of Geratomro's remaining Planetary Defence Forces, and with several other worlds on the brink of open revolt, the Segmentum authorities decided that a show of force was necessary. The options of Exterminatus and orbital bombardment were considered and then dismissed, for Geratomro was a promising Industrial World whose resources might one day again benefit the Imperium.

As isolating the Gerat System through the use of a naval blockade would take too long to bring the rebels to their knees, it was decided that a planetary assault using ground forces was the only realistic option. Several preexisting Battlegroups of the Astra Militarum were redirected to Geratomro and after their initial successes they were forced to face not only Heretic Astartes of the traitorous Emperor's Children Legion, but also elements of an unidentified Traitor Titan Legion.

The carefully laid plans to bring Geratomro back into the Imperial fold with as little planetary damage as possible had to be dismissed once the Imperial forces needed to ensure that the servants of Chaos could not unleash their most terrible allies into realspace -- the daemonic legions of the Chaos Gods.

Thanks to the actions of a small contingent of Black Templars Space Marines of the Michaelus Crusade and the heroic contribution of Honoured Lieutenant Colaron Artem Lo Bannick of the 7th Paragonian Super Heavy Company, the daemonic incursion was prevented and Geratomro was not transformed into a new Daemon World in service to the Ruinous Powers.

Prelude
When Lord Commander Solar Macharius secured the High Lords of Terra's support to launch the Macharian Crusade in the early 41st Millennium, the Lord Solar turned to the Adeptus Administratum, and more specifically the Departmento Munitorum, to assemble the countless regiments of Astra Militarum that would be needed to reconquer the Halo Zone in the name of the Emperor.

All across the Segmentum Pacificus and the Segmentum Tempestus, Departmento Munitorum Assessor Teams began to exact the Imperial Tithe, claiming men and materiel for the new Imperial Crusade. However, due to the setbacks later encountered by the Lord Solar's armies, the tithes expected from the worlds supplyign the Crusade steadily increased.

The Devil's Choice
In 394.M41, a new Munitorum delegation under the authority of both Senior Assessor Borowik and Tithemaster Querol was dispatched to Geratomro. The world's ruler, Planetary Governatrice Missrine Huratal I, was reluctant to welcome the envoys for it was the ninth time in only seven Terran years that the Departmento Munitorum had demanded that Geratomro provide more troops for the Macharian Crusade.

While Geratomro had readily complied with all the prior requests, this time the planetary government of Geratomro intended to refuse the Imperial envoys: the previous tithes had bled Geratomro dry of manpower. Women and children now worked in the fields and in Geratomro's manufactoria. Most of the world's men had been drafted into the Planetary Defence Forces, a necessary measure since some of the moons of Gerat V had already been attacked by xenos raiders. Any further loss of manpower would render Geratomro unable to meet the requirements of the Exacta, the Imperial Tithe of economic resources gathered by another division of the Adeptus Administratum.

Vainly, Missrine Huratal I pleaded for the Administratum envoys to turn back and leave Geratomro in peace. She argued that if they were to leave, the Macharian Crusade would merely be short 50,000 troops while Geratomro would still be able to fulfill the requirements of its tithe to the Departmento Exacta. Even the xenos  -- while posing a threat -- could be held at bay with the forces the governor had at her disposal. In short, the human cost of an invasion of Geratomro to enforce compliance would doubtlessly be far higher than the number of troops the Administratum wanted to raise from the world.

This message was continuously relayed to the approaching Tithe Fleet, first through astropathic message and once they had reached Geratomro's orbit, through hololitic communication, but still Senior Assessor Borowik and Tithemaster Querol could not be swayed. A confrontation was inevitable.

The Envoys of Terra
As soon as the Tithe Fleet arrived in low orbit around Geratomro, the Administratum delegation pushed for a meeting with the Planetary Governatrice. A delegation numbering several hundred individuals was assembled and brought planetside to the planetary capital of Magor's Seat. Almost immediately, Senior Assessor Borowik demanded to be received by Missrine Huratal I, a meeting she delayed for several solar hours.

This show of resistance by the Planetary Governatrice only served to further unnerve the senior Administratum envoys. Finally, the Governatrice's personal armsmen, the Yellow Guard, opened the towering doors to the great Hall of Magor, Missrine Huratal's throne room. A wave of incense preceded the Administratum delegation as it proceeded towards the throne accompanied by the augmented, droning chants of several hundred Priests of the Adeptus Ministorum. To the sound of hymns to the Emperor's glory and magnificence, the vast retinue advanced behind its master, Senior Assessor Borowik.

The senior Adept of the Administratum was a tall, slender man, his almost corpse-like thinness revealing that he had been born on a low gravity world. On Geratomro where the gravity was at best average, the Senior Assessor had to rely on a piston-assisted, medical exo-skeleton called an Ambulator Frame to move at all, a stark contrast to the mountains of flesh and fat that constituted the gathered Geratomran nobility. But despite his physical frailty, the Senior Assessor advanced without fear along the great Hall of Magor, betraying a confidence the Planetary Governatrice mistook for the arrogance of a conquering general.

having expected a difficult audience, Borowisk's retinue fielded a great number of armed guards, anonymous men in the black uniforms of the Administratum's own battalions rather than soldiers of any particular regiment of the Astra Militarum. But the majority of the advancing column went unarmed: ecclesiastical Priests, robed Adepts bearing Data-Slates, Lexmechanics detailing the events on great strips of parchment, Servo-Skulls measuring everything from the hall's dimensions to the circumference of the ornate hats the noblemen wore and other Servitors whose back-mounted generators filled the air with a continuous hum once the hymns had stopped.

"Lady Governatrice, your tithe is overdue! You flout the primary and only rule of planetary governership. Release the military assets owed or pay the consequences. This is your only warning," Borowisk said with a powerful voice. It was a requirement of his position, a show of strength and determination that the Departmento Munitorum would not and could not allow one world to go unpunished for withholding the Emperor's Harvest.

Quite incongruously, Missrine Huratal I did not answer the Senior Assessor but began to tell the gathered assembly a fairy tale well-known on her world -- the story of the Devil-in-the-Bush. It was a cautionary story intended to teach Imperial citizens never to accept a gift from the baleful denizens of the Warp. The tale concerned the notion of "a devil's choice," a choice where both options invariably led to the same tragic outcome, be it death, ruin or devastation. It was a deveil's choice that the Administratum was forcing upon Geratomro: refuse the Departmento Munitorum and be punished or refuse the Departmento Exacta and be punished nonetheless. Faced with such an impossible choice, Missrine Huratal I decided on an alternative: refuse both demands and hope that the Imperium of Mankind currently lacked the strength of arms to mete out the promised retribution.

In response, at Borowisk's signal, the Administratum guards levelled their Lasguns at the Planetary Governatrice and opened fire. But Missrine Huratal I barely flinched. Her personal Conversion Field flickered brightly, absorbing the first shots before her Yellow Guard -- who had taken up perfect firing positions during her story-telling -- cut the emissaries down in volleys of disciplined lasfire. A few noblemen and noblewomen died in the cross-fire, but the Administratum delegation was slaughtered to the last Adept. Geratomro was now in rebellion against the Imperium.

Within a single solar hour of the insurrection's start, Geratomro's main Adeptus Arbites precinct had been leveled by concentrated artillery fire while the Tithe Fleet was attacked by Geratomro's Defence Lasers. With their Void Shields lowered, the Departmento Munitorum's fleet suffered heavy losses but remained on station to land the troops of General Jonathan Hern. Despite fierce fighting, the mostly Cadian troops were unable to capture the spaceport of Matua Superior and were forced to retreat. Thus did the campaign remembered as the Geratomran Reconquest begin in defeat.

Imperial Response
With the initial recovery force having suffered heavily under the Traitors' assault, it was clear that Geratomro's resistance needed to be broken before it sparked a new wave of revolts across the Agritha Sub-sector -- and possibly beyond. In truth, the Imperium generally had only four options to deal with rebellious worlds: an Exterminatus action, orbital bombardment, planetary isolation or a planetary assault.

The first two options were quickly dismissed, for the Imperium was loathe to sacrifice an inhabitable planet without good reason. Likewise, as Geratomro's orbital defences were still operational it was too risky to unleash the warships of the Imperial Navy for an orbital bombardment. While blockading and isolating Geratomro and leaving it over to neglect was a viable option, the several solar decades or even Terran centuries required for this kind of venture to succeed would have an immediate and deleterious affect on the Macharian Crusade's supply lines.

In order to reestablish Imperial Law and present an example to other worlds considering rebellion, a great show of strength was required, a display of power which would let every potentially seditious Imperial Governor in the sub-sector know what happened to those who defied the will of the Lords of Terra.

To show the rebellious world the true strength of the Imperium's armed forces, much consideration was given to the composition of the final battlegroup, with great care taken to ensure that every major Adepta of the Imperium was represented. Fortunately for the senior Adepts of the Departmento Munitorum, such forces were already near-by.

Having fought alongside Battlegroup Kalidar in the Kalidar War, a small Crusade Fleet of Black Templars Space Marines was still available and was more than willing to lend their strength to the Geratomran Reconquest. Likewise, the Adeptus Mechanicus had previously deployed a single maniple of Battle Titans from the Legio Crucis to the sub-sector capital of Agritha to ward it from the attention of the Aeldari. It was seconded to the Geratomran Reconquest after some minor negotiations

In the end, no less than three full-fledged battlegroups of the Astra Militarum were rerouted to Geratomro, a mighty show of force intended to deny the rumours of the Imperium's weakness.

Forcing a Landing
Hostilities began on 082.398.M41 when the gathered Imperial forces moved to capture the city of Matua Superior, a landing zone chosen for the presence of a spaceport. Since the Imperium wished to capture both the city and spaceport intact, the attacking Astra Militarum regiments were under strict orders to limit collateral damage and unnecessary destruction to the surrounding infrastructure.

Orbital landings are among the most dangerous operations undertaken by Imperial forces and even conservative estimates placed the losses suffered during the transfer from orbit to surface at 20%, a testimony to the potency of Matua Superior's air-defence network. The brunt of the assault was carried out by the men of the 477th Paragonian Foot which was supported by all the super-heavy tank companies available to the campaign.

The troops disembarked in a torrential rain, Geratomro's climate wracked by the stress put on it by the supporting Lance-strikes of the Imperial Navy. For while Matua Superior was to be captured intact, the city surrounding it would not escape unscathed. While quite humble in size, the solar months of waiting between the two Imperial landings had given the defenders time to considerably fortify the city's surroundings. These fortifications included a trench system and a cordon of defensive bastions. With the rain turning the ground into a quagmire, the assaulting Imperials readied themselves for a difficult fight.

Under the oversight of Captain-General Iskhandrian of Atraxia, Matua Superior was assailed from three directions at once. The northern landing zone was given over to the Atraxian regiments who were ordered to capture and hold the port facilities before the enemy could sabotage them. From the west, the remains of the initial reclamation force were ordered to venture further into the city and link up with those elements left behind on Geratomro which had until now been laying siege to Matua Superior. The main assault would come from the south and was given to the united Paragonian Regiments of Battlegroup Genthus and Kalidar. Their mission was to capture the southern landing zone before pressing into the city.

The Fall of Matua Superior
Ferried planetside by the heavy-duty landers of the Imperial Navy, both the 7th and 8th Paragonian Super Heavy Tank Companies were deployed to support the 477th's advance. Due to a malfunction of one of the landing claws, the 7th's command tank, the Hellhammer Ostrakhan's Rebirth remained locked in its transport position, forcing the three remaining super-heavy tanks of the company to advance without their commanding officer.

Under the guidance of Honoured Lieutenant Corlaron Artem Lo Bannick of the Baneblade Cortein's Honour, the 7th Paragonian Super Heavy Tank Company spear-headed the assault on the city. Their task was to eliminate Matua Superior's most potent defences, a fortified battery of Macrocannons with direct lines of sight on the southern landing fields.

Located in big, fortified bastions of ferrocrete, these towers posed a serious threat to the entire landing if not destroyed. Fortunately, the enemy was slow to turn this artillery towards the Imperials, a fact which indicated either a lack of training by the Planetary Defence Militia or a serious lack of manpower.

As the first shells landed on the southern landing zone, the crew of the transport still holding Ostrakhan's Rebirth choose to take off despite Honoured Captain Hannick's vehement protests that he and his tank would not be ferried off-world again. Just as they took off, the lander was hit by a glancing shot by the Macrocannons, and it crashed back to earth and caught fire. Ostrakhan's Rebirth, feared lost, shot its way out through the burning debris of the transport and emerged more or less unscathed into the pounding rain.

In retaliation, the company's sole Shadowsword, Lux Imperator, fired its mighty Volcano Cannon at the Marcrocannon battery, neatly decapitating one of the towers and silencing its gun. As Ostrakhan's Rebirth churned through the mud, intent on rejoining the leading elaments of its company, the general order to attack the city was given.

The more advanced Baneblades, Cortein's Honour and Artemen Ultrus, were overtaken by the swifter Leman Russ Battle Tanks of the Paragonian 42nd Armoured Regiment and the 322nd Armoured Veterans. Lux Imperator tried to fire again, but the capricious weapon refused to comply, forcing both Baneblades to the fore in order to deal with the remaining Macrocannons.

While it took them several shots to zero in, before long the Baneblades' Mega Battle Cannons were hammering the leftmost tower, slowly eating away at its wall before the giant gun at its top was toppled. The last remaining gun emplacement continued to fire, albeit more slowly than its counterparts. Three Macrocannon shells hit the landing zones, destroying two light landers and annihilating an entire Platoon of the 477th just as it was disembarking.

Colonel Sholana of the 42nd Paragonian Armoured called in a Lance strike to silence the last tower, but the shot went wide, leaving the Baneblades to finish the job. A lucky shot killed the Macrocannon's crew, finally freeing the 7th Paragonian Heavy Tank Company to secure the landing zone. Now the attack on Matua Superior could begin in earnest.

As the other regiments of Battlegroup Genthus deployed in their own landing zone, the 7th Company received new orders to link up with the Stormlords of the 8th Paragonian Super Heavy Tank Company and take out a big link in the fortifications protecting the city's approaches. This was a fort in the shape of a six-pointed star. Four of its branches featured turret-mounted artillery pieces firing at the regiments of the 2nd Gulem Recovery Force.

After a quick exchange on the Vox, the two companies commanding officers agreed to deviate from the original plan and speed up the attack, the 8th following in the 7th Company's wake to better shield the complement of infantry within their hulls and without whom they would be unable to secure their objective. Lux Imperator was tasked with targeting the forts' main weapons and silenced all but one before another malfunction struck. The tank's Machine Spirit was obviously still not back to its normal self after it had been captured by the Orks on Kalidar.

With their most potent weapon out of order, the Hellhammer and Baneblades would have to carry the load for the Imperial assault, but the fort was well constructed and at long range even the Mega Battle Cannon shells of Cortein's Honour and Artemen Ultrus simply ricocheted off the fort's thick armour. The only option left was to close with the target so that the Baneblades' and Hellhammer's Demolisher Cannons could open a breach for the Stormlords. But this meant daring the fort's complement of heavy weapons -- mostly Lascannons and Missile Launchers -- which could well harm the super-heavy tanks.

Fortunately for the tankers, the Geratomran Planetary Defence Militia was not very experienced and failed to do any real damage. The 7th Company's three advancing tanks soon opened up with their own twin-linked, sponson-mounted Heavy Bolters, which targeted the fort's firing slit and forced its occupants to seek shelter. Combining their fire for more effect, the Baneblades and the lone Hellhamer fired all of their primary and secondary weaponry at once, finally opening a breach in the fort's armoured sides. As if on cue, Honoured Lieutenant Hurnigen confirmed Lux Imperator was ready to fire and a second breach was opened.

The Stormlords surged forward. Using their tanks' armoured weight as primitive battering rams, Honoured Lieutenant Lo Parrigar's "Lucky Eights" broke through the weakened portions of the fortress' walls, clearing the space behind with a thunderous roar and stream of shells from their Vulcan Mega Bolters. As soon as the weapons cycled down, the embarked troops emerged from the Stormlords' troop compartments and began clearing the fort. Soon the Company Standard of the 477th Paragonian Foot's 8th Company was flying over the fort, indicating its capture.

The capture of the fort heralded the end of the fight. With their primary defensive fortification in enemy hands, the spaceport lost and the Atraxians pressing in from the north, the defenders of Matua Superior lost heart. Other regiments pressed deeper into the city and by the seventh hour of the landing, Matua Superior's lord civil sued for peace and offered an unconditional surrender of all his remaining troops.

Imperial Justice
Even before the capitulation had become effective, Imperial justice was dealt out to those who had turned from the Emperor's divine light. Any who had taken up arms against the soldiers of the Imperium, met a swift end by firing squad. Matua Superior's ruler would ultimately suffer a similar fate but not before the Imperium had reestablished its full control over the city.

On the local day following Matua Superior's surrender, more than five thousand men of the Astra Militarum participated in a grand parade across the city. Representatives of all the regiments fighting on Geratomro were convened to march down the ceremonial avenues, the parade led by the metal beasts of the two super-heavy tank companies: the Paragonian 7th and the Atraxian 18th. Servo-skulls hovered over the parade relaying words of encouragement to the conquered populace which dutifully cheered the marching troops on. From the city's streets, the population could also observe the descent of the great coffin-ship carrying the mighty battle-engines of the Legio Crucis, the Titans' arrival precisely scheduled to coincide with the parade as another show of force to cull Geratomro's remaining hostile cities.

At the end of the parade, the troops filled into the great square beneath the Basilica of the Emperor's Light, Matua Superior's greatest religious edifice, while they waited for the conclusion of the procession. A great stage had been erected the night before, a thing of brutish architecture with the notable exception of its lectern which was shaped like an Aquila, its wings spreading to either sides. Two crude cages had been hung from gibbets, their doors open and waiting for their occupants.

At a prearranged signal, the Servo-skulls scattered all over the city, ready to relay what would happen in the square. The door of the great cathedral opened and a great Imperial delegation filed out of the Basilica, General-Captain Iskhandrian at their head. Matua Superior's twin rulers, the Lord Civil and the city's military commander, Colonel Maden, as well as other Geratomran dignitaries captured by the Imperial troops, were ushered forward and brought onto the stage guarded by the Tempestus Scions of the Atraxian Guard Paramount.

After a sermon from the army's most senior Priest, Colonel Maden was brought forth and read a statement from the lectern in which he repented his sins, denounced himself and his men as fools and cowards for having been led astray by the false promises of a corrupt planetary ruler. Yet he rejoiced, for by his actions he hoped to earn the Benevolent Emperor's forgiveness.

After this speech, both the Lord Civil and the Colonel were led to the cages and firmly locked within them. This caused some hilarity amongst the Ogryns of the 36th Ogryn Auxilia for the bulk of the fat Lord Civil's body was too great to easily fit in the cage and he needed to be forced within by two Atraxian troopers. Once his cage was locked, the Atraxian Guard Paramount began assembling wood beneath them before two grim-looking troopers thrust burning torches into the piles. The screams of Matua Superior's burning leader were dutifully transmitted across the entire city while the gathered troops watched on in silence.

What may be seen as gratuitous cruelty was in truth a deliberate act: by showing the ruthlessness of Imperial justice and offering to show some leniency in its execution, General Iskhandrian hoped to bring other local leaders to lay down their weapons before the arrival of the Imperial troops.

Within two solar days of the capture of Matua Superior and the death of its rebellious rulers, five major settlements surrendered.

Advance on Magor's Seat
While all across Geratomro the defenders broke or surrendered in the wake of Matua Superior's fall, there was one notable exception: the Yellow Guard, Missrine Huratal's elite troops, who remained fanatically loyal to the House of Magor which they had protected for thousands of Terran years. While not numerous enough to hold an entire frontline, the Yellow Guard had been tasked with the defence of Geratomro's capital city, Magor's Seat, and were wise enough not to trust only in static defences. The Yellow Guard had taken up defensive positions across the major arteries linking Matua Superior to Magor's Seat, effectively locking down the approaches to the Imperial army's ultimate objective with a minimum of troops.

The Yellow Guard conducted several cleverly devised ambushes and delaying actions that considerably slowed the Imperial advance. Frustrated by these delays, Captain-General Iskhandrian ordered his heaviest elements to the front, but even against the Super Heavy Tank Companies, the Yellow Guard was able to hold its on. The 7th Paragonian Super Heavy Company was targeted by a suicide attack, the Yellow Guard using Augur-detectable landmines to block the road, forcing the Emperor's mighty engines of war to cross across fields where they risked becoming bogged down by the muddy terrain.

This fate befell the Hellhammer called Ostrakhan's Rebirth and effectively disrupted the 7th's formation. The Yellow Guard counterattacked with seven Leman Russ tanks which nevertheless were able to immobilise the Baneblade Artemen Ultrus by targeting its tracks. Worse yet, the Shadowsword Lux Imperator suffered another catastrophic system failure which killed its gunner and injured several other crew members. For the relatively modest price of a few score of infantrymen and seven regular tanks, the enemy had reduced the fighting strength of the 7th Paragonian Super Heavy Company by 75%.

Only a few solar minutes after the suicide attack an urgent message reached the 7th Company: elements of the 477th Paragonian Foot were requesting their assistance to take a strategically vital objective.

Hill Seven-Beta
Designated Hill Seven-Beta, the target was a small fortress created through the combination of rugged natural terrain and man-made obstacles.

The hill was a modestly-sized rocky outcrop, but it dominated the predominantly flat landscape stretching between Matua Superior and the great Drava Highway leading to Magor's Seat. The source of the Drava River was atop Hill Seven Beta, a small stream that grew into a large river several miles downstream. The hill ran from the northeast to the southwest, parallel to the main road leading out of Matua Superior. The Yellow Guard had established a hardened artillery redoubt there, enhancing the hill's natural defences with tank traps, reinforced trenches and pill-boxes.

Two previous attacks by the 477th had already been repelled with severe losses. During the first assault, the 16th Company had lost all its Chimeras to well-trained heavy weapon teams, mostly man-portable Autocannons and Missile Launchers supplemented by a few Lascannons. The second assault had benefited from the support of five Leman Russ tanks but the armoured support had drawn out the defenders' main asset: an extremely rare Destroyer Tank Hunter. With that tank's Heavy Laser Destroyer making short work of the Imperials' Leman Russes, the second assault had failed as well.

In the meantime, the Yellow Guard's artillery hammered the main road, which was clogged by traffic. Between those companies and regiments moving towards Magor's Seat and the wounded returning to the field hospitals in Matua Superior, the road was crowded with Imperial troops. The continuous downpour had turned the unpaved road into a quagmire, causing an ever-growing traffic jam. In such conditions, every single artillery shell wreaked havoc. The Imperials had no choice but to reduce Hill Seven-Beta if their assault on the planetary capital was to continue.

As the only vehicle still combat-ready in the entire 7th Paragonian Super Heavy Tank Company, the Baneblade Cortein's Honour was ordered to help the 16th Company with the capture of their objective. The Baneblade advanced slowly, the traffic on the road forcing it to move parallel to the highway, across fields and orchards where the Baneblade's lumbering speed was greatly reduced. Seven solar hours passed before Cortein's Honour even got to the combat zone. Seven long hours that cost countless lives.

Cortein's Honour linked up with 16th Company under Captain Lubin Lo Santelligen just as the enemy artillery had finally zeroed in on the 16th's command post in a requisitioned agricolae. With the first ranging shots falling around the farm-buildings, Hounoured Lieutenant Colaron Vor Anselm Lo Bannick had little time to devise a battle-plan.

His intent was to use the Baneblade as a shock-assault element, attacking the hill from the north-northeast as the previous assault had done but to evacuate the position before the Destroyer could get its bearings. Cortein's Honour would then circle the hill and attack from the opposite direction which the enemy believed safe because it was too steep for conventional armoured vehicles to cross. However, with its greater mass and lower centre of gravity, the Baneblade could go where the lighter Leman Russes could not.

However, this plan put the supporting infantry at great risk, leaving them without armour cover and facing enemy fire for twenty solar minutes while Cortein's Honour moved into position -- a fact Captain Lo Santelligen clearly resented.

Covered by the fire of their own Heavy Weapons Squads, the 16th Company of the 477th Paragonian Foot mounted their third assault on Hill Seven-Beta, distracting the enemy while Cortein's Honour repositioned itself. As predicted, the Baneblade was able to climb the steep slope previously identified by Honoured Lieutenant Lo Bannick.

The super-heavy tank attacked the Yellow Guard's vulnerable rear, blasting them with all its weapons. With commendable speed, the enemy Destroyer turned around to engage its designated target. While Cortein's Honour fired the first shot in their duel, the huge shell of its Mega Battle Cannon missed, the Destroyer's low hull and terrain making it a difficult target.

In response, the Destroyer scored a direct hit on the Baneblade's turret, but a slight bump in the terrain caused the shot to go slightly awry. Its blast punctured the Baneblade's thick armour and ravaged the inside of Cortein's Honour, molten metal showering one of the crewman, killing him. The beam marginally missed the Baneblade's tactical officer whose console was obliterated, but he escaped only with second degree burns on half his face and right arm.

With the Destroyer having found its mark, Cortein's Honour used its Smoke Launchers to hide behind a thick cloud of white smoke. The Destroyer fired twice into the thick wall of smoke, missing the Baneblade both times. At the second shot, Cortein's Honour 's logic-engines calculated the Destroyer's approximate location.

Surging out of the cloud of concealing smoke at full power, the Baneblade delivered the killing shot before turning its multiple guns on the remaining defenders, its Demolisher Cannon proving most effective in cracking open enemy bunkers so the infantry of 16th Company could clear them in brutal close-quarters fighting.

When the sun rose, it found Hill Seven-Beta in Imperial hands. The 477th Paragonian Foot reported no captives.

Coup d'État
While the forces of the Yellow Guard desperately sought to slow the Imperial advance, both sides blissfully ignored the profound changes wrought in the planetary capital of Magor's Seat.

During a confused night of which several diverging accounts exist, both the Planetary Governatrice Missrine Huratal I and her designated heir, her artificial child Missrine Huratal II, were slain. The throne of Geratomro's planetary ruler therefore fell to Dostain Huratal, the architect of Geratomro's rebellion against the Imperium -- for it was he who had suggested to Missrine Huratal I not to give in to the demands of the Departmento Munitorum.

What truly happened remains uncorroborated, since every person involved was slain in the later stages of the rebellion, but the evidence suggests that Dostain Huratal was in league with another official in the line of succession, Pollein Huratal, and together they conducted a bloody coup, no doubt on the orders of far more sinister masters. Following the change of government, the first trace of the involvement of Chaos in the outbreak of the rebellion was found on Geratomro.

The Advance Resumes
With the successful capture of Hill Seven-Beta, the Imperial advance could resume, it pace further quickened by the end of the storms that had followed in the wake of the planetary landing. Captain Lo Santelligen's men were ordered to remain on-site, holding the position in case of an enemy counterattack none of the officers truly believed was likely.

After the end of the fight, the crewmen of Cortein's Honour were able to take stock of the damage done to their tank. The Baneblade had lost its right sponson-mounted Lascannon, and while the Twin-linked Heavy Bolters were salvageable they responded sluggishly to the commands of Third Gunner Leonates. The Heavy Laser Destroyer of the enemy tank-hunter had caused the most damage: two of the super-heavy's Cogitators had been destroyed and the other three were functioning below optimal capacity, their Machine Spirits in shock at the death of their comrades.

As a result, several systems were nonoperational such as the logic-engines, tactical hololithic projection and targeting arrays. The long-range Vox, initially deemed salvageable, ultimately proved too damaged to restore, requiring Honoured Lieutenant Lo Bannick to use the 16th Company's Vox to report back to Honoured Captain Lo Hannick for new orders.

Overall, Cortein's Honour’s ability to function was impaired but not compromised: its engines and weapon systems were still working even if the systems supporting them were not. The Baneblade's crew would need to adapt and fight a war like the tankers of Old Earth had -- alone, without communication and relying solely on their skills and the marksmanship of their gunners.

Although Captain Lo Santelligen clearly wished to see Cortein's Honour remain with his company, the Baneblade had received different orders. After one local day of rest and repairs, the super-heavy tank was supposed to link up with other elements of the Imperial advance on Highway 4 and make straight for Magor's Seat. A forward base was scheduled to be erected a short distance from the planetary capital to serve as a staging ground for the final Imperial assault.

Instead of using the crowded road which would have slowed them down, Cortein's Honour navigated the vast fields bordering the Drava to link up with its convoy at one of the bridges crossing the wide river. Honoured Lieutenant Lo Bannick had to rely on physical, printed charts to get his tank to the rendezvous point, though the nice weather allowed the Baneblade's crew to enjoy a modicum of Geratomro's true natural beauty.

After passing several abandoned villages, Cortein's Honour discovered a pair of railroad tracks heading towards the capital that it could follow. The tracks' path took the Baneblade straight to Highway 4. It was only as they approached the coordinates provided by Honoured Captain Lo Hannick that the crew noticed something was amiss.

A New Enemy
As night fell upon the lone Baneblade, the sky to the east was illuminated by the telltale sign of an orbital bombardment. Believing it to be the work of the Imperial Navy, the crew of Cortein's Honour observed the process with cold detachment while the Baneblade continued to follow the railroad tracks to its destination. Little did they know that the lights and explosions illuminating the night sky were in truth the work of the enemy.

The Geratomran rebels had somehow contacted off-world reinforcements. A small Chaos warfleet had broken out of the Immaterium, using the local sun as a means to escape Augur-detection, and the warfleet had breached the Imperial Navy's blockade to reach Geratomro and deploy its troops. While ultimately the Chaos fleet was outgunned and was not able to hold orbital superiority for long, the Chaos forces' landing could not be prevented. The most elite of the foot-soldiers of Chaos had come to Geratomro, the dreaded Chaos Space Marines -- veterans of the Long War which had raged since the end of the Horus Heresy, ten thousand Terran years before.

As formidable as their Loyalist brothers, the Heretic Astartes did not waste any time mustering their troops, deploying directly in the teeth of their opponents' advance. While a small contingent of Chaos Space Marines secured Magor's Seat against the Imperial troops mustering to assault it, other elements where left to roam the countryside around the planetary capital, seeking out and destroying the columns of reinforcements still moving down from Matua Superior. Cortein's Honour unintentionally encountered one of these ambushes.

Driving through the night, the Baneblade had made good progress. Its crew was even allowed to take short periods of rests with the notable exception of their driver, a transfer from the notorious Savlar Chem-Dogs. In the early hours of the next morning, the tank's commander, Honoured Lieutenant Colaron Vor Ansem Lo Bannick was woken abruptly by a blazing light. This was produce by the beams of the Baneblade's Searchlight and headlights reflecting off a thick wall of fog. Conscious that the luminescence could draw unwanted attention, the Honoured Lieutenant immediately ordered that the lights be kileld. With the fog still thickening, the Baneblade was forced to slow down, for Cortein's Honour could only navigate by eye, since its Augur systems were still out of order.

The first sign of something awry came as a sickly-sweet scent that rose impossible from the marshlands the tank was crossing. As a cautionary measure, Honoured Lieutenant Bannick ordered his crew to don their Rebreathers. At the first opportunity, the Baneblade left the railroad tracks, and slowly approached the rendezvous point. Still unknown to the Baneblade's crew, the railroad tracks had in fact led them across the Drava River so that they were ahead of the coordinates they were supposed to reach.

The fog began to clear and as the crew looked out at their surroundings they could make out the mighty pillars of the bridges allowing Highway 4 to cross the Drava. Raising his Magnoculars, Bannick could clearly see that one of the pillars was missing, which had caused the bridge to collapse. Calling everyone to battle-stations, Cortein's Honour cautiously lumbered closer.

Ambush on Highway 4
With the bridge gone, Honoured Lieutenant Lo Bannick correctly assumed that the armoured column they were supposed to link up with was caught on the other side of the river. To confirm his assumption, the Baneblade's commander ordered his vehicle up the highway to try and locate the promised convoy. Once at that location Cortein's Honour sighted an immobilised column of vehicles, mostly Leman Russ battle tanks and Chimera APCs as well as a few flat-bed trucks. But the column didn't move. In fact nothing was moving. Raising his Magnoculars, the Honoured Lieutenant could see that the first vehicle in the column was nothing more than a burnt-out shell.

With the identity of the enemy still unclear, Cortein's Honour needed to properly assess the situation. This meant crossing the Drava and getting a look for themselves. The crew was in luck, for while the Drava was a wide river, at the junction with Highway 4 it was not very deep. Since the riverbed had been consolidated with pebble stones, the super-heavy tank could attempt to cross it without getting bogged down. The only precaution needed was to close all the lower hatches and the Baneblade would be good to go.

The Baneblade's driver took Cortein's Honour across the Drava, moving slowly to prevent water entering through the exhaust pipes into the tank's mighty generatorium. The water sizzled and turned into vapour where it touched the Baneblade's engines. but Cortein's Honour made it across without further impediment. As they passed the height of the broken pillar, Bannick's First Gunner carefully studied the structure's broken remains. His conclusion was unequivocal: the concentrated blast-marks indicated that the bridge had been brought down by Demolition Charges and no Battle Cannon. The bridge had indeed been sabotaged. But the identity of the perpetrator remained unclear.

As the Baneblade drew near, the crew could make out the telltale sign of carrion birds flying over the column, confirming their worst suspicions. Stopping at a safe distance from the immobilised column of vehicles, Cortein's Honour hid in the leeway of the earthworks carrying Highway 4 towards the broken bridge. Bannick decided to progress on foot, taking with him the two most expendables members of his crew, the First and Second Loaders, a Paragonian of the Vaskigen Clan and another transfer from one of the warrior clans of the Feral World of Bosovar, a small pinkish man named Gollph. Having armed themselves with Lasguns from the Baneablade's small armoury, the three men investigated the fate of the Imperial column.

Hundreds of corpses littered the four wide lanes of the highway, some having already started to bloat in the warm midday sun. The road was painted red by the blood of fellow Imperial soldiers, the bodies broken open and severed limbs lying all about. The gore was such that Vaskigen initially thought that the Drukhari might be responsible, but to the trained eye the slain Guardsmen displayed the wounds typical of people slain by mass-reactive bolts.

This observation was quickly confirmed when further down the ambush site the trio encountered the first enemy casualty: it was undoubtedly a Space Marine, but its appearance was vastly different from that of the Black Templars Bannick had witnessed fighting on Kalidar. The dead Astartes' Power Armour was clad in violent hues of pink and purple. Had Bannick possessed the necessary security-clearance he would had quite easily identified the livery of the Emperor's Children Traitor Legion, the Heretic Astartes dedicated to the service of Slaanesh, the Dark Prince.

The slain Chaos Space Marine carried an archaic Bolter, the weapon's sides decorated with the carvings of leering faces. Now that he knew what he was looking for, Bannick quickly identified several dead Astartes, all of them lying in a heap of slain foes. He also recognised one of the burnt-out husks as a Rhino, an armoured troop transport almost exclusively used by Space Marines.

Bannick was about to order a hasty retreat to the security of the Baneblade when Gollph discovered a survivor. The soldier's face was covered in blood and both his arms and legs had been broken, but he was undoubtedly still alive, his cracked lips trying to say something none of them could hear. Gollph was reluctant to draw closer as on Bosovar booby-trapping the corpse of a defeated enemy was a common enough tactic, but Vaskigen was not so careful.

Upon seeing the Paragonian uniform of the severely wounded man, he rushed to help his comrade from another regiment, springing the trap. Both the helpless victim and the First Loader were torn to pieces by an explosion, perhaps a hidden Krak Grenade. Had the Second Loader not jumped upon Bannick and pressed him to the ground they too would have been slain by the explosion.

If the trap failed to do maximum damage, the explosion did not fail to draw the enemy's attention. Somewhere out of sight, engines began revving, prompting the two surviving tankers to hurriedly leave the ambush site and join their comrades in the Baneblade. Rushing back to their tank, Bannick ordered his driver to prep the engine via his Micro-bead, and Cortein's Honour’s powerful power plant sprang back to life.

Perhaps half a Terran mile down the highway, their opponents came out of their hiding places, including three tanks Bannick quickly identified as Predator Annihilators, dedicated tank-killers thanks to their two pairs of Lascannons. Far lighter than the lumbering Baneblade, the Predators capitalised on their greater speed to close with their new target. Even launched at full speed, the Predators rained terribly accurate lasfire upon Cortein's Honour. Two quickly broke off to the right, trying to attack the Baneblade from its wounded side. Cortein's Honour began to back away, firing its guns but all of its shots missed due to the Metus Astartes, the psychological shock regular human beings face when first fighting the transhuman Space Marines.

The Predators continued to press the advantage, trying to get a clear shot at the Baneblade's back where its armour was the thinnest. Third Gunner Leonates raked one of the Predators with Heavy Bolter fire, damaging one of its sponson-mounted Augur arrays and disabling one of his target's Lascannons. Almost in response, one of the other Predators scored a direct hit on the Baneblade's vulnerable turret windows, melting the armourglass. Even if the Baneblade's armour was proof against their weapons, the enemy could disable Cortein's Honour in a number of different ways.

The Baneblade was herded back to the Drava, the enemy undoubtedly thinking to catch the super-heavy tank between their guns and the river. Obviously they didn't know that the river posed no true obstacle to Cortein's Honour. Two of the Predators were still driving on the highway, using the road's elevation to fire down at the Baneblade. The thirds followed a parallel course to their own, making sure to stay out of the Demolisher Cannon's frontal firing arc. Its turret-mounted weaponry destroyed the Baneblade's left sponson, bringing its tertiary weaponry down to one pair of Heavy Bolters.

Barely slowing down so as not to drown its engines, Cortein's Honour reached the Drava and slithered down the banks into the water. With two of their enemies still on the highway, the Baneblade made a sharp right turn, placing itself directly beneath the bridge. Cortein's Honour’s turret tracked the remaining Predator as it reached the riverbank and killed it with a direct hit of its Mega Battle Cannon. The crew cheered at their first kill, but the two remaining enemy tanks were still at large.

The Emperor's Children decided to split up, one remaining on the bridge while the other descended on the left side on the highway to flush the enemy out from under the bridge. As the second Predator entered the Drava it emerged on the Baneblade's wounded left side. Again a steady stream of ruby lasbeams began to hammer Cortein's Honour.

Alarms sounded inside the super-heavy tank as the Predator on the bridge finally got a fix on the Baneblade. Cortein's Honour retreated further into the deeper waters of the Drava, its more powerful engine allowing it to put some distance between itself and the pursuing Predator. The Mega Battle Cannon roared again, shooting at the tank above it but it only succeeded in blowing a piece of rockcrete from the bridge's fabric. Every crewman aboard the Baneblade realised that the enemy was gaining the upper hand.

The true mettle of an Imperial Tank Commander is his ability to find a solution to his problems even in the thick of a seemingly hopeless fight. By any accounts, Honoured Lieutenant Colaron Vor Anselm Lo Bannick was such an exceptional officer. Faced with a numerically superior and more mobile enemy, Bannick took the only sensible decision he could: rob the enemy of its advantage by forcing it to run right into the guns of his own tank.

Bannick ordered his driver to take shelter between the two legs of the great pillars supporting the highway's bridge over the Drava. Its flanks secured by the huge pillars of rockcrete, the front arc of the Baneblade would be secured by its Demolisher Cannon, while the rear was covered by the tank's main armament. Either way the enemy attacked, he would face a weapon capable of annihilating it with a single shot.

As the solar seconds stretched into minutes, the nervous crew of Cortein's Honour believed the enemy would not take the risk, but in the end the Chaos Space Marines' constant blood-lust won out. The two remaining Predators attacked the Baneblade simultaneously, one from the front and one from the rear.

The first caught a Demolisher shell head-on and exploded in spectacular fashion, but the second proved luckier when the armour-piercing shell from the Baneblade's Mega Battle Cannon glanced off its angled turret armour. Swearing, the First Gunner quickly reloaded as the Predator turned all four of its Lascannons on Cortein's Honour, readying itself for the killing blow.

With nothing left to lose, Honoured Lieutenant Bannick ordered Cortein's Honour to ram the lighter tank, the Baneblade surging backwards. This unexpected movement threw off the Predator's aim and instead of hitting the Baneblade's engines, it pierced one of Cortein's Honour’s auxiliary fuel tanks, causing it to detonate and showering the Baneblade with burning Promethium.

Cortein's Honour crashed into the enemy tank, the Baneblade's greater weight slowly pushing the lighter tank into deeper water. Once they reached the end of the gravel bed, the Predator began to sag, allowing the Baneblade to upturn it. Before the Predator's crew could bail out, a final shot from Cortein's Honour rang out, obliterating the last of its enemies.

A Hero's Welcome
The failed ambush against Cortein's Honour had cost the tank dearly, resulting in further damage. The confrontation with the final Predator had taken its toll on the Baneblade's engines and it was only by disengaging the reactor's safeties that Cortein's Honour was able to move at all. Resolute, the Baneblade followed Highway 4 to its final objective: the Astra Militarum castella established outside Magor's Seat.

When the super-heavy tank finally reached the gates of the Imperial encampment, it found a citadel under siege. Artillery fire sporadically fell around the perimeter while the sky was filled with the burning trails of orbital debris from the naval battle raging over Geratomro. In the distance, no more than twenty kilometers away, the spires of Magor's Seat could be seen, the sky over the city filled with the multiple rocket flares of descending vessels from orbit. What was supposed to be the last stepping stone leading to a crushing victory had now become a fortress under siege.

When Cortein's Honour presented itself before the castella's main entrance, it found its gates closed and the mouths of several heavy weapons pointed at it. Two octagonal rockcrete bunkers flanked the gates, further reinforced by walls of piled sandbags. A sentry, a sergeant-at-arms of the Cadian Shock Troops, approached Baneblade, a look of surprise on his face. Honoured Lieutenant Lo Bannick soon learned why -- the Baneblade had been assumed destroyed alongside the rest of the convoy. After the briefest of examinations, the sentry let them pass, indicating where the 7th Paragonian Super Heavy Company was billeted.

As the Baneblade crossed into the Imperial encampment, a ragged cheer welcomed them, the infantrymen -- especially those from Paragon -- applauding the Baneblade's unexpected return. The cheers of their fellow soldiers warned the members of their unit long before the turret of Cortein's Honour could be seen so that by the time the Baneblade reached the small courtyard where the other engines of the company were parked a small crowd had gathered. Even the Tech-priests stopped their inspection of the other super-heavies to assess the damage on Cortein's Honour. Almost as soon as Bannick had climbed down from his cupola, Honoured Captain Hannick was there ushering him into his tent for an urgent briefing.

Race To Victory
During Bannick's absence, Hannick's health had greatly deteriorated so that the briefing was frequently interrupted by his violent fits of coughing which left him out of breath. Still, Hannick insisted upon conducting the briefing himself.

In less than 24 solar hours, the Archenemy had managed to turn the tables upon the soldiers of the Astra Militarum. As soon as the Chaos fleet had reached Geratomro's orbit, it had begun landing its troops, mostly small mobile units which immediately began to attack the army's lines of reinforcements and supply-lines. It was just such a group that Cortein's Honour had encountered.

Stretched out over a large front, the Imperial units been butchered, the army now encamped at the gate of the enemy capital cut off from its rear lines. The 7th Company itself had lost all its supporting elements to just such an attack, which considerably weakened their abilities off the battlefield. The enemy had the sense not to engage the remainder of the 7th, but had focused its attention on destroying the company's support elements: the troop-transport conveying the company's Tech-adepts, the mobile manufactoria, the motive shrine and the Atlas Recovery Tanks. All had been lost in the enemy attack.

The situation in orbit was as chaotic as on the ground, with the enemy fleet holding positions above Magor's Seat and still in the process of landing yet more troops on Geratomro. The Imperial Navy had maneuvered to protect the castella, both fleets fighting at what was for them point-blank range. Several Chaos attacks on the castella had already been repelled with the aid of the Imperial fleet. The Imperial Navy's bombardments kept the base safe from further ground attacks and an orbital assault by the Chaos Fleet. Both fleets were waging a fierce naval battle for control of the world's orbital space above their heads.

The Chaos troops on Geratomro's surface had yet to receive their heaviest elements, for amidst the vessels of the Chaos fleet was a huge transport vessel akin to an Ark Mechanicus. This meant that within the next several solar days the enemy would benefit from the arrival of dreaded Chaos Titans.

The prospect of facing the powerful engines of destruction of one of the dreaded Traitor Titan Legions struck fear in most Imperial hearts. While the Astra Militarum encampment benefited from the support of a small detachment of Titans from the Legio Crucis, these included only two of the lighter god-engines, the Warhound-class Scout Titan War's Gift and Princeps Yolandesh's own steed, the Reaver-class Battle Titan Ultimate Sanction. This represented too small a force to successfully face the mightiest creations of the Dark Mechanicum.

To counter this threat, Captain-General Iskhandrian had ordered the battlegroup's three Super Heavy Tank Companies -- the 18th Atraxian and the 7th and 8th Paragonian -- to form two ad-hoc units, Groups Epsilon and Ultra, which would be placed directly under the command of Princeps Yolandesh.

While Group Epsilon would support the army's advance on Magor's Seat and act as bait for the enemy Titans, Group Ultra would include all the Imperial army's Shadowswords and lay an ambush for the Chaos god-engines At the same time, Iskhandrian revoked his order limiting collateral damage, for any fight involving Space Marines would be a difficult one that required his troops to unleash every weapon at their disposal.

Almost as an afterthought, Honoured Captain Hannick informed his officers that an Inquisitor named Lord Militant Vesh had attached himself to the army's command staff and had begun issuing orders of his own -- every tank of the 7th Paragonian Super-Heavy Company would henceforth be accompanied by a Commissar.

In truth, Imperial High Command had not shared all of its intelligence with the troops on the ground. Inquisitor Vesh had recognised that the Emperor's Children were employing delaying tactics and that the enemy was fixated on achieving its victory through unconventional means. All pretense at strategy was dropped for one desperate and mad dash for Magor's Seat, a final attack that would decide the fate of Geratomro.

The Fate of Lux Imperator
As the other officers of the 7th Paragonian Super Heavy Company left the tent, Honoured Captain Lo Hannick asked Bannick to stay and discuss the status of Cortein's Honour. While the Baneblade had suffered dearly during the last engagements, the Honoured Lieutenant was confident that the Adeptus Mechanicus would be able to repair Cortein's Honour in under five solar hour.

Reluctantly, Hannick refuted this claim: the loss of their supply train would mean that Cortein's Honour’s much-needed repairs would need to wait until after their victory -- even the battleworthy super-heavy tanks would need to be resupplied using the stock of the Paragonian 8th and Atraxian 18th. While the tank was operational, Hannick vehemently refused to let Cortein's Honour leave the camp, convinced that the absence of a functioning Vox would put the whole venture in jeopardy. However, this didn't mean that the Baneblade's crew couldn't join the fight for Geratomro's capital.

The Enginseers attached to Hannick's command had successfully convinced the Honoured Captain that the Shadowsword's traumatized Machine Spirit was to blame for the series of malfunctions Lux Imperator had suffered on Geratomro. During the 7th's previous deployment on the Desert World of Kalidar, Lux Imperator had indeed been captured by the Orks and forced to fight the soldiers of the Astra Militarum before being recaptured by the forces of the Imperium. Having both served alongside and fought against Lux Imperator during this conflict, the Engineseers believed that Honoured Lieutenant Lo Bannick somehow shared a sympathetic link to the tank and that he would be able to master it. It was also their belief that by slaying a worthy enemy in battle, the imbalance in Lux Imperator’s humors could be revised. Therefor, Honoured Captain Lo Hannick ordered Bannick to merge the crews of Cortein's Honour and Lux Imperator in anyway he saw fit and assume temporary commandment of the Shadowsword.

Without great surprise, Bannick choose to rely mostly on his own crew, a particularly wise choice considering that his own First Gunner, a Paragonian named Meggen, was also trained in the use of sophisticated Targeting Arrays of the Shadowsword's mighty Volcano Cannon. In the end, Bannick replaced all the crewmembers except for Lux Imperator's attached Tech-Priest. By direct order of Lord Inquisitor Vesh, a Commissar would also be attached to each and every super-heavy tank, thus completing the crew.

The Battle for Magor's Seat

Imperial Order of Battle
The reclamation of Geratomro was only rendered possible through the combined efforts of no less then three previously independent Astra Militarum battlegroups and their respective reinforcements. Below is the Imperial order of battle for the Geratomran Reconquest with its nominal fighting strength at the beginning of the campaign in 398.M41.

Battlegroup Geratomro
Battlegroup Geratomro was formed to accompany Senior Assessor Borowisk to Geratomro. Intended more as a show of force to impress Planetary Governatrice Missrine Huratal I, the initial reclamation force was ill-prepared for the sudden violent actions undertaken by the Renegade Geratomran Planetary Defence Forces and suffered heavily while the Tithe Fleet was still in orbit. The battlegroup's core was comprised of experienced but severely depleted regiments of Cadian Shock Troops.

Designated Commanding Officer : General Jonatan Hern

Astra Militarum Regiments

 * 415th Cadian Infantry Regiment (strength at 18%)
 * 754th Cadian Armoured Regiment (strength at 28%)
 * 89th Cadian Artillery Regiment (strength at 76%)
 * Fourth Jupian Ironlords (strength at 17%) - The Ironlords are officially designated infantry regiments, however the low technological base of their homeworld means that the Ironlords do not meet the Departmento Munitorum's requirements for frontline service and need to be reequipped with more advanced weapons befitting the battlefields of the 41st Millennium. While petitioned to do so, the Departmento Munitorum had yet to reequip the regiment at the beginning of the Geratomran Reconquest.
 * First Drani New-Pledged (Infantry) (strength at 56%)
 * Second Drani New-Pledged (Rough Riders) (strength at 72%)
 * 36th Ogryn Auxilia (strength at 63%)

Battlegroup Kalidar
Battlegroup Kalidar doubtlessly fielded the most experienced troops of the entire campaign, as some of its regiments were veterans of the Dentares Suppression. By the time of the Geratomran Reconquest, the battlegroup had successfully concluded the Kalidar War and the follow-up actions on the sub-sector capital world of Agritha. Only the second wave of reinforcements raised from Bosovar was still unblooded. While mostly comprised of Paragonian Regiments, command was given to an Atraxian general.

Designated Commanding Officer : Captain-General Iskhandrian, advised by Grand Captain Olgau (Cc/ref Atraxian Command Protocols, Sibellius' Guide to Imperial Guard Regiments of the Segmentum Tempestus)

Astra Militarum Regiments

 * 121st Atraxian Mechanised Infantry (heavy infantry) (strength at 37%)
 * 122nd Atraxian Artillery (strength at 90%)
 * 18th Atraxian Super Heavy Tank Company (generalised) (full strength)
 * Atraxian Guard Paramount (Tempestus Scions)
 * 31st Bosovar Levy (strength at 99%) - The four regiments of Bosovar Levies were raised in 396.M41 on the Feral World of Artemis V.
 * 32nd Bosovar Levy (strength at 99%)
 * 33rd Bosovar Levy (strength at 100%)
 * 34rd Bosovar Levy (strength at 100%)
 * 23rd Paragonian Foot (strength at 50%)
 * 62nd/84th Mechanised Infantry (strength at 83%) - The 62nd/84th Mechanised Infantry Regiment was created by the fusion of the severely depleted 62nd Mechanised Infantry Regiment, a veteran of the Dentares Suppression and the 84th Paragonian Foot Regiment in the wake of the Kalidar War. The Paragonians, with their natural affinity for mechanised warfare, adapted quickly and performed well despite serving under mostly foreign officers.
 * 63rd Paragonian Mechanised (strength at 26%)
 * 42nd Paragonian Armoured (strength at 54%) - The 42nd Paragonian Armoured Regiment was officially disbanded at the end of the Kalidar War and its numbers reassigned for a future founding of a new regiment. The remains of the old 42nd remained with the battlegroup.
 * 322nd Paragonian Armoured Veterans (strength at 29%)
 * Seventh Paragonian Super Heavy Tank Company (multirole) (strength at 100%)
 * 12th Savlar Light Infantry (strength at 72%)
 * 13th Savlar Light Infantry (strength at 57%)

Adeptus Astartes
Having also fought on Kalidar, the battlegroup's association with the Space Marines of the Black Templars Chapter continued throughout the Geratomran Reconquest. Led by the visions of their newly appointed Emperor's Champion, the members of the Black Templars' Michaelus Crusade would distinguish themselves on Geratomro by slaying Lord Damien Bastoon of the Emperor's Children and the Herald of Slaanesh and closing the Warp Rift that threatened to unleash a full-fledged daemonic incursion across the sector.

Designated Commanding Officer: Marshall Michaelus
 * 90 Battle-Brothers and associated support elements

Adeptus Mechanicus
Having fought alongside Battlegroup Kalidar on Agritha, Battlegroup Geratomro would benefit from the presence of the remainder of one maniple of Battle Titans of the Collegia Titanica, their unparalleled capacity for destruction enough to cow the rebellious Geratomrans into submission. While already depleted, the presence of these Titans proved instrumental in vanquishing the enemy's own Titan support.

Designated Commanding Officer: Princeps Yolandesh of the Legio Crucis
 * Ultimate Sanction (Reaver-class Titan)
 * War's Gift (Warhound-class Titan)

Battlegroup Genthus
Battlegroup Genthus was mainly comprised of the Paragonian Regiments of the 2nd Gulem Recovery Force which since its inception in 395.M41 had exclusively fought human insurrectionists and secessionists.

Designated Commanding Officer : General Maden Heldor Lo Basteen

Astra Militarum Regiments

 * 477th Paragonian Foot - The 477th Paragonian Foot was a double-size regiment.
 * Paragonian Black Suns (Tempestus Scions)
 * 109th Paragonian Artillery
