Thramas Crusade


 * Thramas Crusade (ca. 005-008.M31) - During the opening days of the Horus Heresy, the Warmaster Horus sent Night Haunter and his Night Lords Legion and their allies, including the Legio Ulricon, on a campaign of genocide against the Imperial strongholds of Heroldar and Thramas in the Aegis Sub-sector of the Eastern Fringes, thus protecting Horus' flank and delaying the Dark Angels Legion from reinforcing the Loyalists on Terra. This bitterly contested campaign dragged on for nearly three standard years, until the Dark Angels successfully broke the back of the Night Lords Legion and their allies in a meticulously executed ambush in space while the Traitors were in transit. During this engagement, the Legio Ulricon suffered the loss of their flagship along with dozens of Titan war engines, which tumbled out into the void after the Legio Ulricon 's flagship was badly damaged.
