Later, Nobunaga retainer Toyotomi Hideyoshi, subsequently abandoned his campaign against the Mōri clan to pursue Mitsuhide to avenge his beloved lord. Hideyoshi's intercepted one of Mitsuhide's messengers trying to deliver a letter to the Mōri requesting to form an alliance against the Oda after informing them of Nobunaga's death. Hideyoshi managed to pacify the Mōri by demanding the suicide of Shimizu Muneharu in exchange for ending his siege of Takamatsu Castle, which the Mōri accepted. Mitsuhide failed to establish his position after Nobunaga's death and Oda forces under Hideyoshi defeated his army at the Battle of Yamazaki in July 1582, but Mitsuhide was murdered by bandits while fleeing after the battle. Hideyoshi continued and completed Nobunaga's conquest of Japan within the following decade.
