Toyotomi Hideyoshi (20,000) vs. Akechi Mitsuhide (10,000)
Learning of the death of Oda Nobunaga at the hands of Akechi Mitsuhide, Hideyoshi quickly signed an armistice with the Mori and raced back to the Kyoto region. Akechi, who had failed to gather any support beyond those familes already loyal to the Akechi, was confronted at Yamazaki on 2 July. His troops failed to take the locally important Tennôzan and were routed when flanked after Hideyoshi's army forced a crossing of the Enmyôji River. Mitsuhide himself was killed attempting to flee to Sakamoto Castle, which fell soon afterwards to Hori Hidemasa. Yet, as fate would have it, Oda Nobunaga himself was killed by Akechi Mitsuhide just days later, and the Uesugi would be granted a reprieve.
