The Luxor Uprising was a recent campaign conducted by the Novamarines Space Marine Chapter on the industrial Hive World of Luxor in 812.M41. The cruel ruling Oligarchs of this world were overthrown by a workers' uprising backed by the insidious Chaos Space Marines of the Alpha Legion, with several of that Traitor Legion's warbands making planetfall in surprise attacks to support the revolt. The planet itself was a lynch-pin of the Departmento Munitorum-dominated Helioret Sector which was vital to the wider supply of war materiel to the northern Segmentum Ultima.
The Novamarines rightly feared that should Luxor fall, it could start a chain reaction that might leave a hundred other worlds vulnerable. Without the time to wait for reinforcements, or for the slow grinding wheels of the Segmentum authorities to act, the Novamarines gathered what forces they could and attacked immediately before the rebels could crush all local resistance and become entrenched.
In the swift, savage war that followed, the Novamarines excelled in the urban fighting over Luxor's war-torn hive-citadels, bringing their superior combat abilities to bear in the tangled warrens of shattered rubble, cancelling out the rebels' massive advantage in numbers. The Chapter's Land Raiders and Predators likewise proved their supremacy over the Traitors' tanks, which were crewed by inexperienced conscripts. The Astartes armour destroyed them in huge numbers. The war tipped in the Chapter's favour when the Novamarines assault reserves cornered and overran the Alpha Legion forces guiding the failing rebellion in an anarchic battle at the planet's principal star port.
A Terminator-led attack struck the deathblow and finished the encircled Alpha Legion Astartes, putting the few survivors to flight. With the remaining Traitors driven back in disarray from their initial gains and cut off from the Alpha Legion's command and direction, the Novamarines led the rallying Imperial Loyalists in a brutal offensive which left over 400,000 recidivists dead and restored Luxor to Imperial rule within a standard year.
