Balance of power in 1560
In 1560, Oda Nobunaga was a minor lord, the son of a deputy shugo, with a small holding near modern-day Nagoya. Hideyoshi was a foot-soldier. Tokugawa Ieyasu was a hostage of the powerful Imagawa family.
In 1560/5 Imagawa Yoshimoto attempted to march on Kyoto, passing through the territory of a minor lord, Oda Nobunaga. The Imagawa forces outnumbered the Oda 40,000 to 2000, but Nobuanaga set an ambush. Using muskets and superior strategy, Nobunaga drove back the invaders. Imagawa Yoshimoto himself died on the scene.
