After defeating the Taira and driving them into the western provinces, Yoshinaka took Kyoto and desired to be the leader of the Minamoto clan. His cousin Yoritomo was prompted to crush Yoshinaka, and sent his brothers Yoshitsune and Noriyori to kill him. Yoshinaka fought Yoritomo's forces at the Battle of Awazu on February 21, 1184, where Tomoe Gozen purportedly took at least one head of the enemy.
