In 1180, Kiyomori commands his followers to defeat Yoritomo under the name of the former Emperor Takakura. Although Yoritomo loses the battle against the Taira forces at Mt. Ishibashi, he vows to realize Yoshitomo's long-cherished wish to build a true samurai-oriented country with the backing of powerful anti-Taira samurais. On October 20, the Taira forces led by Koremori (Shigemori's son) and the Minamoto forces led by Takeda Nobuyoshi stand face to face near Fuji River--the Battle of Fujikawa. The Taira forces, however, flee in fear from the battlefield, mistaking the sound of water birds for a surprise night attack by the Minamoto forces.
