1584: The Battle of Komaki-Nagakute
Oda Nobukatsu, whose relations with Hideyoshi had deteriorated, allied with Tokugawa Ieyasu and raised arms, and the two sides faced off in Owari. In localized fighting at Nagakute, Ieyasu's forces gained the upper hand, killing prominent Hideyoshi commanders Mori Nagayoshi and Ikeda Tsuneoki, but when Nobukatsu made a separate peace with Hideyoshi in November, Ieyasu withdrew as well, leaving the conflict without a clear resolution.
