Battle of Komaki and Nagakute
In 1584, Nobunaga's other son, Oda Nobukatsu, remained hostile to Hideyoshi. Nobukatsu allied himself with Tokugawa Ieyasu, and the two sides fought at the inconclusive Battle of Komaki and Nagakute. It ultimately resulted in a stalemate, although Hideyoshi's forces were delivered a heavy blow. Ieyasu and Hideyoshi never actually fought against each other themselves but the former managed to check the advance of the latter's allies. Finally, Hideyoshi made peace with Nobukatsu, ending the pretext for war between the Tokugawa and Hashiba clans. Hideyoshi sent Tokugawa Ieyasu his younger sister Asahi no kata and mother Ōmandokoro as hostages.
