  • 428-430.M41 The Fall of the Tellurian Combine - The dominating commercial power of the Tellurian Combine is uncovered as a front for the malefic Chaos Cult called the Brotherhood of the Horned Darkness. Such is the group's widespread power and infiltration, even of the Lucid Court, that rather than risk civil war and an open purge, the Inquisition's local Ordos Calixis declares a shadow war against the Brotherhood, which lasts for three standard years and involves what is believed to be the largest employment of both the Officio Assassinorum and the Grey Knights in the sector’s history before its conclusion. An unforeseen side affect of the widespread secret purges and fearful suspicion they create is a dramatic and long-term weakening of the sector’s central government which has detrimental effects for centuries to come.

  • 742.M41 The Damocles Gulf Crusade Begins - The Damocles Gulf Crusade, also called the Damocles Crusade, was the first military conflict fought between the Imperium of Man and the rapidly expanding Tau Empire in the Lithesh Sector of the Ultima Segmentum in the galaxy's Eastern Fringes during the late 41st Millennium. The conflict essentially ended in a stalemate, as the Imperium was forced to conclude its military offensive early to deal with the encroaching Tyranid threat while the Tau sought to begin diplomatic negotiations with the Imperium to show humanity the benefits to be had by accepting the Greater Good. Members of the Tau Water Caste had established trade agreements with Imperial worlds on the frontier of the Tau Empire, near the Damocles Gulf region of the Ultima Segmentum in the galactic east, and exchanges of goods and technology were common. Alarmed by the threat of alien contamination, the Administratum readied a suitable response and almost a century later, the Damocles Crusade smashed into Tau space, destroying several outlying settlements and pushing deep into the Tau Empire. When the Imperial fleet reached the Tau Sept world of Dal'yth Prime, however, the Crusade ground to a bloody stalemate as the formidable numbers and high technology of the Tau and their Kroot allies thwarted every attempt to capture the world or its star system. Many months of terrible fighting ensued with nothing gained on either side. By late 742.M41 the Crusade's commanders eventually agreed to requests from the Tau Water Caste for peace talks. The negotiations were successful and the Imperial fleet withdrew from Tau space unmolested, primarily due to the impending approach of the Tyranid Hive Fleet Behemoth. Or, depending on the source, the Damocles Gulf Crusade was ended in 988.M41 due to the emergent threat of Hive Fleet Kraken.

The renegade unleashes blasphemous horrors and forbidden weapons seemingly at random in order to further his research or avenge himself on his enemies.

Upon learning of the threat posed to Ultramar by the vicious Tyranids, Chapter Master Marneus Calgar at once drew up his plans. Calgar declared that the Hive Fleet would be halted at Macragge before it consumed more of Ultramar or drove deeper into the heart of the Imperium. Deeming Macragge to be the star system most immediately threatened, Calgar ordered its formidable defences to be further improved. Scant weeks later, the outrider vessels of the Tyranid fleet attacked Macragge. With the Hive Fleet destroyed after the sacrifice of an Imperial Battleship created a Warp vortex that destroyed the majority of the Hive Fleet, Calgar's surviving starships came about and roared back to Macragge to try to save the beleaguered polar garrisons. Calgar, feeling that the situation was becoming critical, sent the 3rd and 7th Ultramarines Companies ahead in their fast Strike Cruisers while his remaining damaged ships limped back to Macragge. Despite horrendous losses inflicted upon the Tyranid fleet from the orbital and polar defence grids, many Tyranid organisms were able to reach the surface of the planet. The Tyranid swarm swept across the planet with the most intense fighting in the region of the northern polar defence installations. Despite the Ultramarines fleet's ability to destroy the Tyranid bio-ships, horrific casualties were suffered by the planet's population as well as the Chapter. Calgar went down to the planet's surface, leading the 3rd Company against the ravenous hordes of the Great Devourer. The entirety of the elite 1st Company was wiped out to a man whilst defending the northern pole's defence grid. The Ultramarines 1st Company was gone and the 3rd and 7th sorely diminished. It would be many long years before the Chapter could properly replace its losses, but replace them it would.
  • 746.M41 The Scouring of Ultramar - Lord Commander Dante recognises that the Tyranid Hive Fleet Behemoth's invasion of the Realm of Ultramar is but the first of many scourges that will befall the galaxy at the hands of the Great Devourer.

Before it can be destroyed, the final Space Hulk disgorges thousands of Orks commanded by the Warlord Big Skorcha, onto the surface of Baal. Knowing that the bulk of the Blood Angels forces are still in orbit destroying the Space Hulks or on the two moons of the world, Big Skorcha aims to lay siege to and ransack the Chapter's fortress-monastery. However, the Blood Angels prove not so easily outmanoeuvred. The Chapter's Dreadnoughts, deemed unsuitable for use in the cramped confines of the Space Hulks had remained behind on Baal. With the remains of WAAAGH! Big Skorcha still at large, the Venerable Furioso Dreadnought Astramael assembles all 41 of the Blood Angels' Dreadnoughts and coordinates the defence of the fortress-monastery in what was later known as the Battle of Iron. Although Astramael and his Dreadnoughts needed only to defend the fortress-monastery long enough for Astartes reinforcements to arrive from orbit, they fought with such savage fury that there were precious few Orks remaining when the first Stormravens finally landed.

The mutants have formed together into a unified faction calling itself the Pale Throng, led by a cabal of terrifyingly powerful witches and mutant-psykers known as the Shroud Council. As rumours of the successful rebellion spread, so do brushfire revolts and uprisings on other worlds in the sector, and the flames of malcontent are fanned. Lord Sector Hax realises the wider threat to Imperial order and declares a mass counter-invasion of the war-torn world to bring the rebellion to heel, calling on the Inquisition to dispose of the Shroud Council, which they do, whilst the Ordo Hereticus launches Operation Bellerophon to decapitate the mutant forces. At huge cost in lives and at the price of laying waste to much of Tranch, the Pale Throng is crushed, but its many factions manage to scatter off-world, while sympathisers still raise revolt against the Imperium in the Pale Throng's name elsewhere.

Meanwhile, the furious counterassault by the Bloodcaller 's crew and Astartes swept the Orks who had boarded the Battle Barge from its lower decks and then carried the fight to the Kroozers. Though it took nearly a full standard year for the Bloodcaller to make its way at sublight speeds to the nearest Imperial Navy orbital repair docks at Haringvleet, the great Voidship did so proudly, bearing its scars as a tell-tale sign of the great victory it and its crew had won against incredible odds.
  • 823.M41 The Khartas Incident - Captain Zorael of the 4th Company is killed by the Bloodthirster Greater Daemon Ka'Bandha.

  • 830.M41 The Axonar Spirewar - Lord Commander Dante despatched the Blood Angels' 3rd and 4th Companies to quell a rebellion against the Emperor's authority on the Hive World of Axonar. Determining that the rebel defences at the bases of the world's hive cities to be to potent for his Space Marines to launch a frontal assault, Captain Metraen, the Force Commander for the operation, orders a series of low-orbit insertions onto the cities' upper spires using Jump Packs. Once again trapped behind their own defences, the rebels are easily crushed by the Blood Angels' savage assault.
  • 835.M41 The War For Piety - The Shrine World of Piety rematerialises after being swallowed by a Warp storm two centuries earlier. The planet is, however, almost unrecognisable, having transformed into a hideous Daemon World. Canoness Sariah of the Order of the Sacred Rose immediately leads a force of Battle Sisters to the planet to retrieve artefacts from the Reliquary of Hope, one of the few sites to have withstood the corruption. As the rest of her forces establish a perimeter around the reliquary, Sariah leads several squads into the labyrinthine corridors beneath. For three days Canoness Sariah and her Sisters battle through monster-infested passageways; bolters cut down scores of blood-hungry Daemon-hounds and flamers burn swathes of bloated plague-beasts. Only Sariah and two Celestians survive to rejoin the Battle Sisters on the surface, having recovered the left thighbone of Saint Dolan and three pages from the Lexicon of Falsehoods from a stasis vault. The surviving Battle Sisters withdraw to orbit with their prizes just as a fleet of Grey Knight vessels arrive and lay waste to the planet with cyclonic torpedoes.
  • 843.M41 The Dalaric Campaigns - Three companies of Blood Angels are sent to the world of Dalaric to stop the raids of the deceitful Eldar. The Blood Angels initially earned a string of victories against the forces of the elusive xenos, but the Eldar managed to carry out an ambush that killed almost 100 Battle-Brothers, transforming an easy victory into a catastrophe for the Chapter. Fortunately, at the darkest moment, when it seemed that every Blood Angel might receive the Emperor's peace, the Sanguinor appeared once more, striking down the alien Avatar of Khaine and forcing the remaining Eldar to flee for their lives.

  • 858.M41 The Defence of Dimmamar - Dimmamar, birth world of Sebastian Thor, comes under attack from the Eldar of Ulthwe Craftworld without any warning or reason. Seraphim Superior Ame lda of the Order of the Bloody Rose retaliates, leading her squad of Seraphim in a daring attack to slay the enemy commander - Farseer Kauerith. The Seraphim's pistols blast a bloody path through a score of black-clad Eldar before the Sisters are engulfed in a hurricane of psychic lightning. Though many of her companions fall, Amelda refuses to yield and defiantly advances through the eldritch storm, slaying the Eldar Farseer with a single bolt round to the head.
  • 859.M41 Assault on Zoran - The forces of the insidious Alpha Legion incited an uprising against the Imperium on the Ice World of Zoran. The Blood Angels' Captain Metraen lead elements from the Chapter's 3rd and 8th Companies to that frigid planet to eliminate the rebellion and drive the Traitor Legion from the world. Metraen's bold tactical choice at first seemed to drive the enemy back but the assault stalled when the Alpha Legion's base of operations on the world was determined to be an ancient and long-lost Imperator-class Emperor Titan left from the days of the Horus Heresy. Though still half-buried in the ice of Zoran, the monstrous war engine's Void Shield generators and weapons batteries proved to be operational with devastating consequences for the servants of the Emperor. Many Blood Angels Astartes fell in the first assault against the Titan and Metraen feared that the only course open to him to end the threat was an outright Exterminatus order against Zoran and its people. Fortunately for the innocents of that Ice World, aid arrived in the form of Kor'sarro Khan and the 3rd Company of the White Scars Chapter. Sent to claim the head of the Alpha Legion's infamous Daemon Prince Voldorius, the Khan joined his forces to the remains of the Blood Angels force on the planet. As the White Scars launched their own attack on the Alpha Legion's bastion from below, the Blood Angels used their Stormravens to initate a series of drop assaults against the secondary plasma reacors that powered the Titan's weapons. Metraen's Astartes neutralised the Titan's defences and the White Scars swarmed into the massive war machine's lower levels. Though Voldorius ultimately escaped once more, his followers were exterminated to the last Chaos Cultist and Alpha Legionary. Though Kor'sarro Khan was obliged to continue his hunt for the Daemon Prince, Zoran had been restored to the Emperor's light and the recovery of a battered but fully repairable Imperator Titan was no mean feat. Metraen eventually brought the Titan back to Baal, from which it was sent on to Mars, where Lord Commander Dante hoped that such a priceless gift might finally smooth over the conflicts between the Adeptus Mechanicus and the Blood Angels.
  • 861.M41 Battle of Arconar - Chapter Master Marneus Calgar of the Ultramarines defeats a coalition of Eldar Raiders on the Feral World of Arconar, scattering their forces and capturing their bases both on and off world.
  • 867.M41 - Captain Alessio Cortez of the Crimson Fists breaks through Eldar lines despite suffering 17 wounds including being stabbed through one of his 2 hearts and two hits by heavy weapons.
  • 877.M41 The Mel'yanneth Skywar - Captain Metraen is charged by Commander Dante of the Blood Angels with the destruction of Eldar Corsairs who have been assaulting Imperial commerce from a fortress making use of Eldar anti-gravitic technology hidden in the toxic atmosphere of the gas giant called Mel'yanneth. Making use of the Chapter's entire existing fleet of Stormraven and Thunderhawk gunships, Metraen launched an airborne assault that had no equal in the Chapter's long history. Stormravens cut through the blaze of anti-aircraft fire to disgorge their cargoes of Assault Squads and Terminators directly onto the floating fortress' docking platforms. These Astartes secured the landing zones for heavy armoured vehicles like Land Raiders and Predators which were delivered by a follow-on wave of Thunderhawk Transporters. As the battle then unfolded through the Eldar fortress hangars and maintenance shafts, the overwhelming firepower brought to bear by the Blood Angels was able to scythe through the arcane traps and dishonourable defensive systems erected by the Eldar pirates. Once they realised that they had no chance to stop the human assault, the xenos abandoned the fortress, although not before sabotaging its gravity nullification technology. Metraen was forced to retreat as the fortress was sucked down into the gas giant's grasping depths. Only the incredible skill displayed by the Blood Angels' gunship pilots, who fearlessly plunged deep into Mel'yanneth's gravity well to rescue their Battle-Brothers, prevented what became a famous victory for the Chapter from ending in mournful failure.

  • 941-942.M41 The Second War for Armageddon - The Ork WAAAGH! Ghazghkull descends upon the Imperial Hive World of Armageddon in the Segmentum Solar, initiating the Second War for Armageddon. The Orks are defeated only by the extreme stubbornness of the defenders and the combined might of the Blood Angels, Ultramarines and Salamanders Chapters. Thought dead by his foes, the wily Ork Warlord Ghazghkull Mag Uruk Thraka himself escapes into space. Lord Herman Von Straub's forces are saved by Imperial Guard Commissar Yarrick's performance. The Blood Angels are one of 3 Space Marine Chapters who respond to the strategically-located world's plight. Lord Commander Dante's reputation amongst other Astartes is so great that Chapter Master Tu'shan of the Salamanders and Chapter Master Marneus Calgar of the Ultramarines cede overall command of Astartes operations to him. The fighting proves to be the fiercest in and around the planet's hive cities. The Blood Angels bear the brunt of the close-quarter fighting, primarily because only the overcharged engines of their Lucifer-pattern Rhinos can keep pace with the convoys of roaming Ork Trukks and Battlewagons. The tactical manoeuvrability of the Blood Angels forces is a crucial factor in the later stages of the war. The 3rd Company, under the command of its newly promoted captain, Erasmus Tycho, forms the heart of a spearhead of armoured vehicles that severs the primary Ork supply lines, which leaves the WAAAGH!'s Mekboyz without the necessary materiel to keep the Greenskins' massive Skullhammas and Stompas operational. With its heaviest units thus put out of action, the WAAAGH! is finally broken before the walls of Tarterus Hive, where Dante and Tu'shan famously fought together against Ghazghkull Thraka's own bodyguard of Nobs.

For three weeks, neither side is able to gain an advantage though Dante finds his own tactical acumen stretched to its limits countering the space-time manipulations of the Silent King and the advanced technology of the Necrons. The stalemate is broken when a Tyranid splinter fleet suddenly enters orbit of Gehenna, which forces the two armies to break off from hostilities with each othe to deal with the Great Devourer. This unwanted alliance proves to the downfall for the Tyranids. Following the final battle against the Tyranids at Death's Crag, Dante and the Silent King leave the field without further combat, as each side is now too damaged to guarantee victory over the other. In addition, for the Blood Angels, the idea of turning in combat upon those they had so recently shed blood beside was distasteful in the extreme.

Despite the strength of their forces, the advance is halted when Lord Gralastyx - the Daemon Prince leading the Chaos forces - unleashes a legion of possessed Chaos Space Marines. As the frenzied Chaos horde rips through the Imperium's ranks, Battle Sisters and Space Marines fight back to back, their bolters and flamers blazing away as every warrior endeavours to sell their life dearly. However, the allied forces are saved when Saint Celestine appears, falling upon the Chaos horde like an avenging angel. The Living Saint carves a path through the horde towards Lord Gralastyx, before plunging her blade through his heart. With the death of Gralastyx, the Chaos horde is destroyed, but of Celestine there is no sign, for she vanished as mysteriously as she appeared.

A fierce battle erupts through the tech-vaults and catacombs of Pandrax III. The Blood Angels are the ultimate victors, the Farseer commanding the Alaitoc Eldar sacrifices himself to destroy the very records of advanced genetic manipulation techniques that Corbulo had sought. The search for the cure to the Blood Angels' Flaw must continue elsewhere.
  • 991.M41 The Martyrdom of Praxedes - Canoness Praxedes of the Order of Our Martyred Lady reinforces the Imperial Guard on the cardinal world of Okassis, soon after the start of the Second Tyrannic War. As the Tyranids of Hive Fleet Kraken assault the Ecclesiarchal Cathedral, the combined fire of Retributor Squads and Exorcist tanks obliterates the first wave, but the second manages to breach the fortress- walls. As Tyranids pour through, Praxedes confronts a Hive Tyrant. During the fightin g the Canoness is dealt a mortal wound, but even as her blood ebbs away, she summons the strength to land a final blow, caving in the beast's skull with a thunderous strike from her power mace. With the Tyrant's destruction, the swarm loses all direction. The Sisters waste no time in pressing the assau lt, determined to avenge the death of their beloved leader. The remaining aliens are swept aside, buying the time to evacuate the Ecclesiarchy's priests.
  • 991.M41 The Stromark Civil War - A political rivalry within the Stromark System lead to a civil war between the two manufactorum worlds, Stormark Primus and Stromark Secundus, that coexisted within that star system. The escalating violence halted the flow of much needed weapons and materiel from these planets to the wider Imperium, a situation that the Departmento Munitorum's Adepts determined could not be allowed to continue without adversely affecting the security of the Emperor's realm. As a result, elements of two Successor Chapters of the Blood Angels, the Angels Encarmine and the Flesh Tearers, were despatched to the Stromark System with the mandate to end the conflict by any means necessary. The fighting on Stromark Prime was the first to cease. The first engagement by the Flesh Tearers Chapter was also the last, as stories of unstoppable Space Marines hacking a vicius and bloody path through literally tens of thousands of Stormarkian warriors quickly terrified the planet's recalcitrant population into submission. Stromark Secundus took longer to be pacified, as the Angels Encarmine used less "direct" methods than their savage brethren amongst the Flesh Tearers. Several hours of difficult combat ensued that was brought to an end when 5 of the Chapter's Furioso Dreadnoughts smashed into the Stormarkian Secundus military headquarters and tore the planet's High Command apart. The surviving officers of the planet's Planetary Defence Force wisely agreed to immediately end the conflict with their neighbours and resume meeting the system's crucial production quotas.
  • 992.M41 Second Tyrannic War - Iyanden Craftworld is nearly destroyed by Hive Fleet Kraken. Lamenters Chapter lost. Scythes of the Emperor Chapter badly depleted, its homeworld lost to the Great Devourer.
  • 992.M41 The Hives of Hollonan- In response to a request for assistance, Chief Librarian Mephiston leads the Blood Angels strike force Sanguinatus to the Hive World of Hollonan to deal with an uprising against the authority of the Imperium. What at first appeared to be only a run-of-the-mill, if still large rebellion, was soon revealed to be a deep-seated infestation of Tyranid Genestealers. Mephiston's strike force purged the xenos parasites and their psychically-addicted cult members from the hive cities of Hollonan, but it was already too late for the Hive World -- even as the last brood of Genestealers was brought down in fire and blood, Hive Ships from a splinter fleet of the approaching Hive Fleet Kraken arrived in the Hollonan System Mephiston immediately recognised that his strike force lacked the numbers to repel a Tyranid swarm of that magnitude and so he assumed command of Hollonan's defences and sent an astropathic request for aid to Baal and to Coinal, the nearby Chapter planet of the Blood Angels Successors called the Angels Vermillion. The battles that ensued within the depths of Hollonan strained even the ever-present lust for battle of the Blood Angels. The first assault by the Tyranids eliminated the planetary defence batteries and automated Sentry Guns. The second destroyed the chain of ancient but necessary fusion accumulators that provided Hollonan's hive cities with most of their power. What resulted was a ferocious war for survival in the guts of Hollonan's primary underhive. Mephiston's Blood Angels found themselves stretched to the limit of even their considerable abilities as tried to rally the Planetary Defence Force against the endless swarms of Termagants, Raveners and Carnifexes. Only where Mephiston personally entered the fray did the human defenders hold. Over the course of two terrible weeks, Mephiston proved his worth again and again, never once sleeping or taking rest from combat, though even his fellow Astartes had become weary beyond the measure of mortals of the constant bloodshed. His deeds wrote a new legend for the Chapter. At the Chapel of the Emperor's Repose, Mephiston tore a Carnifex to shreds with his own hands. He held the entrance to the hive city's filtration plant for six hours by himself. In the final hours of that terrible assault, he cleaved his way alone through the spearhead of the Tyranids' primary assault, slaying a Hive Tyrant and all of its hideous guardians before he was himself struck down by a Trygon. Mephiston's fall, which could have easily crushed the last strands of fragile morale amongst the world's defenders, instead led them to redouble their efforts to be worthy of his example. Such was the determination borne in the hearts of the Blood Angels and the soldiers of Hollonan that they held out long enough for reinforcements to arrive. Fresh companies of Blood Angels and Angels Vermillion Astartes came from the sky in Drop Pods and Stormraven gunships just in time to save the world's remaining defenders. Yet the Astartes were not alone, for they had been joined by the Eldar of Craftworld Ulthwe, led by the ancient Farseer Eldrad Ulthran, who had decided to fight beside the guardians of Mankind for reasons of their own. The Tyranids were crushed between the attacks of the three descending armies and this splinter of the coming Hive Fleet Kraken was removed from existence before its parent Hive Fleet arrived in full. Eldrad Ulthran and his forces remained just long enough to see Mephiston recovered from the rubble, terribly wounded but miraculously still clinging to life. This second resurrection only served to increase Mephiston's legend within his Chapter -- and beyond.

  • 995.M41 Beheading the Serpent - Captain Tycho's Blood Angels 3rd Company was one of the many Space Marine strike forces that responded to the threat of the Tyranid Hive Fleet Jormungandr. Though Tycho led his Astartes to numerous crucial victories that turned the tide against this tendril of the Great Devourer, his tactics proved so reckless, even for a Blood Angel, that the Sanguinary Priests of the Chapter began to fear for his sanity.
  • 996.M41 The Battle of the Sepulchre - An Eldar emissary from the Biel-tan Craftworld was sent to the Imperial world of Commrath to enter negotiations with its Planetary Governor for the return of an ancient eldritch artefact from the tomb of one of the Ultramarines' most-lauded heroes, Captain Orar, known as the Sceptre of Galaxian. Refusing his request, the Eldar emissary grew angry and soon his pleas turned to threats of violence. The Planetary Governor refused to be cowed by the arrogant xenos and had the Eldar executed on the spot. However, the Governor had the foresight to heed the Eldar's threats and requested aid from the Ultramarines. Calgar responded with overwhelming force, mobilising his entire Chapter. This would be the first engagement the Ultramarines fought in as an entire Chapter since the First Tyrannic War. The Eldar launched a series of devastating attacks against the tomb complex. Though unsuccessful against the stoic Ultramarines' defenses, fully half the Astartes' number were either wounded or dead. When the third and final attack came, the Eldar looked like they were going to overwhelm the defenders. An Eldar Avatar of Khaine spearheaded the assault, breaking the Ultramarines' lines of defence and spilling into the tomb complex. Dozens of Ultramarines were killed by the mighty Avatar. Calgar valiantly fought the Avatar in single combat, and though grievously wounded, managed to kill the vile creature. With the fall of their War God, the Eldar lost all heart for the fight. Some fled without heed while others fell back in good order, but all retreated into the darkness. Despite overwhelming odds, once again the Ultramarines had emerged victorious, but in his wisdom Calgar knew that the Eldar would return for the Sceptre of Galaxian. So it was that Calgar informed Commrath's Governor that the Galaxian Sceptre would be removed from Orar's Sepulchre to Macragge, where it could be properly defended.
  • 996.M41 Vengeance for Semmel- Commander Dante learns of the location of the Eldar who slew so many Blood Angels on Semmel years before. He orders the Sanguinary Guard to earn the Chapter's vengeance. The strike force caught its quarry in the arid badlands of the world of Zoros. In the resulting aerial combat, Sanguinary Guardians duelled with Eldar Jetbikes and Swooping Hawks Aspect Warriors, but emerged as the victors. Unfortunately, the identity of the individual who betrayed the Blood Angels at Semmel cannot be determined and so final vengeance for that loss remains beyond the Chapter's reach.
  • 997.M41 The Third Tyrannic War and the Defence of Tarsis Ultra - Elements of the Ultramarines and Mortifactors Space Marine Chapters make a stand against one spur of the Tyranids' Hive Fleet Leviathan on the world of Tarsis Ultra. The defenders defeat this tendril of the Leviathan with an engineered anti-Tyranid biological plague, but the remainder of Hive Fleet Leviathan rampages on unabated.
  • 998.M41 - The Administratum Historicus Coran Celecius is tried for heresy by the Inquisition after his work links the Aphis Hermitage Massacre to the Necrons and other mysterious past encounters Mankind has had with that dangerous and enigmatic race.
  • 998.M41 Third War for Armageddon - The Ork Warlord Ghazghkull Thraka returned to the Hive World of Armageddon at the head of the largest Ork WAAAGH! seen since the Ullanor Crusade ten millennia before, unleashing the Third War for Armageddon. Over 2 dozen Space Marine Chapters respond to the Greenskin assault this time, which was necessary as the Blood Angels had been forced to deploy much of their existing strength against the equally dangerous threat of Hive Fleet Leviathan. Even so, honour demanded that the Chapter provide at least some assitancer to Armageddon and Dante sent the 3rd Company and genereous number of suport units. During the course of the campaign, Captain Tycho finally succumbed to the Black Rage and spent his life valiantly on the outer walls of the Hive Tempestora, taking hundreds of Orks with him down into death. The 3rd Company's new commander was Captain Galan Machiavi.
  • 999.M41 - A murderous plot unleashed by the Forces of Chaos kills several members of the Cadian High Command, including the Lord Castellan. Colonel Ursarkar E. Creed is appointed the new Lord Castellan of Cadia.
  • 999.M41 The Taking of Bridge Two-Four - Uriel Ventris succeeds Captain Idaeus as commander of the Ultramarines 4th Company.
  • 999.M41 The San Leor Massacre - A Red Corsairs strike force invades San Leor, the original home world of the Daughters of the Emperor. The Chaos Space Marines are unprepared for the fury of the Adepta Sororitas reprisal, as they come under assault from nine separate Orders Militant and are utterly annihilated by the combined counter-attack.
  • 999.M41 The Zeist Campaign - Captain Cato Sicarius leads an army of Astartes and the Imperial Guard into the Eastern Fringe of the galaxy to halt the Tau's Fourth Sphere Expansion. An Imperial Crusade later known as the Zeist Campaign drawn from 30 Space Marine Chapters drives the Tau back from dozens of Imperial worlds, but is recalled before its work can be completed to deal with the much greater threat of Abaddon the Despoiler's 13th Black Crusade.
  • 999.M41 The 13th Black Crusade - The 13th Black Crusade erupts out of the Eye of Terror led by the Warmaster of the Black Legion, Abaddon the Despoiler. The great Chaos Lord leads the largest Chaotic invasion of the Imperium since the Horus Heresy to the Fortress World of Cadia in the hopes of conquering the world and at last seizing the Cadian Gate for the Dark Gods so that the Forces of Chaos can once again launch themselves towards Terra and depose the hated Corpse Emperor. The Imperium suffers heavy losses during the fighting across the Segmentum Obscurus, but the Black Legion and its allies only captures half of Cadia durign its ground assault. The Chaotic warfleets are forced to retreat back into the Eye after an Imperial counter-offensive. While the Forces of Chaos retain their foothold on Cadia, the Imperial Navy patrols the space above and prevents a Chaotic break-out -- for as long as the stalemate holds.
  • 999.M41 Defence of Ultramar - In the midst of the 13th Black Crusade, the Realm of Ultramar comes under renewed assault from the Forces of Chaos. The Daemon Prince M'kar the Reborn, clad in mortal flesh once again in the body fo a former Ultramarines Dreadnought, leads the onslaught against the world of Talassar. Other Chaotic warlords under the command of the Iron Warriors Warsmith Honsou attack Calth, Espandor and Tarentus. Marneus Calgar recalls all Ultramarines forces to defend Ultramar, dispatching a reinforced Battle Company to each threatened planet. Calgar himself accompanies the 2nd Company to defend Talassar, determined to slay M'kar a hundred times over if need be.
  • 999.M41 The Darkest Hour - The Blood Angels are tested as they have not been since the days of the Horus Heresy. As the launch of the 13th Black Crusade consumes the resources of the Imperium, a tendril of Hive Fleet Leviathan is determined to be on a direct course for Baal. To make matters worse, the dread Bloodthirster Ka'Bandha, the Bane of Sanguinius, returns from the Warp leading an army of daemons. His first blow is struck against Ammonai, the outermost world of the Baal System. Faced with a possible war of extermination for the Chapter on 2 fronts, Lord Commander Dante makes swift preparations, and unites many Imperial and even non-human worlds under the command of the Blood Angels simply for the sake of survival against Tyranid and Daemon alike. Even some former foes of the Chapter and the Imperium are counted in Dante's alliance, though whether or not they can be truly trusted when the time comes remains an open question. Well aware that even these forces will not be enough to repel both foes, Dante recalls the 3rd Company from its operations on Armageddon and sends requests for aid to all of the Blood Angels' known Successor Chapters. The Flesh Tearers are the first to respond and despatch their entire fighting strength to the Blood Angels' aid without question. Ultimately, all of the Successor Chapters save for the Lamenters lend some form of aid to their primogenitor. Even the Knights of Blood, declared Renegade by the Imperium many centuries earlier, heed Dante's call -- though they are very careful to never take the field alongside the other Chapters. The stage is thus set for the defence of Baal, and perhaps the final battle of the Scions of Sanguinius, the Sons of the Angel.
  • 999.M41 - The Adeptus Mechanicus discovers that the Golden Throne has irreparable flaws that could ultimately endanger the Emperor's life.
