* 13th Black Crusade (999.M41) - The Extinction Angels joined the [[Black Legion]] for a major assault on [[Adeptus Mechanicus|Deimos Primary]], where traitors and saboteurs deactivated the world's orbital defenses immediately prior to the assault. While the Black Legion went about destroying the [[Skitarii]] Legions, the Extinction Angels went about crippling the world's manufactorums and production facilities. While the Adeptus Mechanicus did manage to force the bulk of the Chaos forces off-world by deploying [[Titan (Warhammer 40,000)|the Legion Astorum]], the loss of the Forge World's production capabilities crippled the Imperial war effort. The real threat of the attack would not become known for almost a solar month later: Extinction Angel units had remained hidden within the depths of the facilities, and when the Adeptus Mechanicus attempted to get them back online, their forces were slaughtered. Eventually an entire [[Black Templars]] Crusade Fleet was mobilized to hunt down the surviving Extinction Angels on the planet.
