One of the most important bases of the Taira was Yashima, a small island off the coast of Shikoku. In November of 1183, Minamoto no Yoshinaka sent an army to cross the Inland Sea to Yashima, but they were caught by the Taira just offshore of Mizushima (水島), a small island of Bitchu Province, just off Honshu.

The Taira tied their ships together, and placed planks across them to form a flat fighting surface. The battle began with archers loosing a rain of arrows upon the Minamoto boats; when the boats were close enough, daggers and swords were drawn, and the two sides engaged in hand-to-hand combat. Finally, the Taira, who had brought fully-equipped horses on their ships, swam to the shore with their steeds, and routed the remaining Minamoto warriors.
