Operation Batu was an unauthorized invasion of the planet Alshain, held by Clan Ghost Bear in 3062. The strike was mostly planned by the Black Dragon Society. Three of the four Alshain Avengers regiments attempted to retake the world for the Draconis Combine, and were obliterated by the Ghost Bears. The 11th Alshain Avengers were prevented from joining the assault by Clan Nova Cat forces. Theodore Kurita denounced the invasion and labeled the participating Combine units as traitors, but this failed to appease the Ghost Bears, who assaulted the Combine along its border with their Dominion, later called the Combine-Ghost Bear War.
