The Honru Massacre was an event during the Butlerian Jihad. In 195 BG the Army of the Jihad attempted to free the population of the Synchronized World of Honru. An armada of League warships was sent and started the attack. However Omnius used aggressive tactics for defense; 10000 robotic ships had lain in ambush and then engulfed the armada. The human fighters had responded with desperate combat measures, but suicide robot ships wiped out the Jihad battleships. Over five hundred thousand free humans are killed. Waves of combat robots on the surface exterminated villages of humans.
