Battle of Komaki and Nagakute

The Battle of Komaki and Nagakute was a series of battles in 1584 between the forces of Hashiba Hideyoshi and the forces of Oda Nobukatsu and Tokugawa Ieyasu. Hideyoshi and Ieyasu had both served Oda Nobunaga and had not previously come into conflict; this would in fact be their only period of enmity.
