Prelude

Akechi Mitsuhide controlled two castles ( Shōryūji and Yodo) in the Yamazaki region. Learning of the size of Hideyoshi's army and not wanting to be caught inside a castle with his force divided, Mitsuhide resolved to prepare for battle somewhere to the south. Due to its position between a river and a mountain, Yamazaki provided Mitsuhide with choke points that could ease the number of enemies his forces would have to face at any one time. Meanwhile, Hideyoshi decided that a wooded area called Mount Tennōzan, just outside the town of Yamazaki, was key to strategic control of the road to Kyoto. He sent a detachment under Nakagawa Kiyohide to secure this area, while he led the majority of the army to Yamazaki himself. His forces took over the mountain and gained a significant advantage. Mitsuhide arranged his army behind a small river (the Enmyōji-gawa), which provided an excellent defensive position. On the night of 1 July, Hideyoshi's generals Nakamura Kazuuji and Horio Yoshiharu sent a number of ''

'' into the Mitsuhide camp, setting fire to buildings and generally causing fear and confusion, and therefore robbing the enemy of their sleep for most of the night.

Battle

On the following morning, 2 July, the main fighting began as Hideyoshi's men began to form up along the opposite shore of the Enmyōji-gawa from the enemy, and a portion of Mitsuhide's samurai, led by Matsuda Masachika and Nabika Kamon, crossed the river, seeking to make their way up the wooded Tennōzan hill. They were driven back by

, across the river, and into Mitsuhide's front lines. They made some progress, and were soon joined by the left wing, with support from atop Mount Tennōzan. The majority of Mitsuhide's men fled, with the exception of the 200 men under Mimaki Kaneaki, who charged and were destroyed by Hideyoshi's larger force. Soon, panic set in among the Akechi army, and Hideyoshi's army chased them back to Shōryūji, where the garrison collapsed. Mitsuhide himself fled much further, to the town of Ogurusu, where he was killed by a gang of bandits. Mitsuhide is thought to have been killed by a bandit known as Nakamura about two weeks after the battle.
