Doom Eagles - Notable Campaigns: Battle of Thessala (121.M31) - The Doom Eagles were present at the Battle of Thessala, where their Primarch Roboute Guilliman was mortally wounded by the Emperor's Children's Daemon Primarch Fulgrim during the Great Scouring.The Torment (075.M41) - On the Hive World of Pirody, 60 Doom Eagles joined 60,000 Imperial Guardsmen of the Lammark Lancers and the Fancho Armoured Regiments on the orders of the Warmaster Getus to cleanse the world of the forces of Chaos who had conquered the eastern continent and razed its hive cities. In the course of the campaign, the Imperial forces were affected with a supernatural disease that mirrored a hemorrhagic fever, causing explosive loss of blood and hyper-aggression in those afflicted. Even the Astartes were not immune and six of their number contracted the contagion despite their Power Armour's purity seals and their transhuman immune systems. The research for a cure was led by the Apothecary of the Doom Eagles on the planet, Subjunctus Valis. Valis explained to the man who assisted him, Colonel Ferge Ebhoe of the 23rd Lammark Lancers, how the disease was spreading despite environmental conditions that should have slowed or halted it in its tracks. Later it was Ebhoe who discovered that Valis himself had been afflicted by the Nurgle-spawned plague, which had corrupted his mind and led him to produce not vaccines, but ever more virulent versions of the disease. Every attempt to innoculate the Imperial forces and civilians of Pirody had actually spread the Torment further. At the moment of his realisation, Ebhoe turned his Flamer upon the deranged Apothecary in his laboratory, causing the nearby chemicals to explode, killing the corrupted Astartes and crippling Ebhoe for the rest of his life. But Valis' death brought an end to the Torment and allowed the Imperium to reclaim Pirody. That victory cost the lives of 59,000 Guardsmen and an unknown number of civilians lost to the Torment.The Awakening of Faugris (991.M41) - The Doom Eagles attacked en masse upon the theoretically Dead World of Faugris, which turned out to be a Necron Tomb World. After 16 solar weeks of invasion and bombardment the Necron legions were still boiling forth from their stasis tombs in terrifying numbers. The Doom Eagles were ultimately forced to withdraw before Imperial reinforcements could arrive to bolster their deployed strength.13th Black Crusade (999.M41) - At least 5 companies of the Doom Eagles are known to have participated in the defence of the Cadian Sector of the Segmentum Obscurus during the 13th Black Crusade of Abaddon the Despoiler.Defence of Belis Corona (999.M41) - Upon arriving at the Cadian Gate, the Doom Eagles Chapter dispatched forces to a number of warzones, notably areas that had already suffered terribly at the hands of Chaos. The largest of these detachments, under the command of Captain Luctus of the 3rd Company, was involved in operations within the Belis Corona Sub-sector, where the notoriously pious Chapter battled those who had fallen to the Curse of Unbelief. Only those without the strength of faith to resist were afflicted by the plague, and it has been noted that not a single Doom Eagles Battle-Brother was touched by its blight. The Doom Eagles had proven effective in combating the Plague Zombies infesting many worlds of the sub-sector, though, typically for the Astartes of this aloof Chapter, they had refused all offers of support in consolidating these successes.Defence of Yayor (999.M41) - On the Agri-World of Yayor, contingents of the Doom Eagles also defeated the undead horrors unleashed by the Curse of Unbelief (Zombie Plague).Defence of the Deliverance (Imperial Navy starship) (999.M41) - Several squads of the Doom Eagles' Terminator armoured veterans of the elite 1st Company, fought a horrific battle in the close quarters of the corridors of the Imperial Navy carrier Deliverance, whose crew had become infected by the ravaging Zombie Plague and been transformed into undead monsters.Indomitus Crusade (ca. 999.M41 - 111.M42) - The Doom Eagles were among the Chapters who contributed their forces to their resurrected primarch's Indomitus Crusade after the birth of the Great Rift.
