Battle of Komaki and Nagakute
Hidemasa led portions of Hideyoshi's forces once again, in the 1584 Battle of Komaki and Nagakute, in which they suffered a crushing defeat at the hands of the Tokugawa army. Ambushed by Ōsuga Yasutaka and Sakakibara Yasumasa, they successfully held off their attackers for a time, but upon meeting the main Tokugawa force of 9,000, were forced to retreat.
