From Warhammer 40k - Lexicanum
The Blackfang Crusade was an Imperial Crusade by the Blood Angels in 994.M41. Judging that the Ork strongholds in the Blackfang System have defied the Imperium for too long, Dante mobilises his entire Chapter. They fight a year-long campaign that not only drives the Orks from the the twelve worlds of Blackfang, but also from two neighbouring systems.
