The battle of Dan-no-ura (壇ノ浦の戦い Dan-no-ura no tatakai?) was a major sea battle of the Genpei War, occurring at Dan-no-ura, in the Shimonoseki Strait off the southern tip of Honshū. On April 25, 1185, the Genji (Minamoto) clan fleet, led by Minamoto no Yoshitsune, defeated the Heike (Taira) clan fleet. The morning rip tide was an advantage to the Taira in the morning but turned to their disadvantage in the afternoon. The young Emperor Antoku was one of those who perished amongst the Taira nobles.
The Taira were outnumbered, but some sources say that they had the advantage over the Minamoto in understanding the tides of that particular area, as well as naval combat tactics in general. The Taira split their fleet into three squadrons, while their enemy arrived en masse, their ships abreast, and archers ready. The beginning of the battle consisted mainly of a long-range archery exchange, before the Taira took the initiative, using the tides to help them try to surround the enemy ships. They engaged the Minamoto, and the archery from a distance eventually gave way to hand-to-hand combat with swords and daggers after the crews of the ships boarded each other. However, the tide changed, and the advantage was given back to the Minamoto.
One of the crucial factors that allowed the Minamoto to win the battle was that a Taira general, Taguchi Shigeyoshi, defected and attacked the Taira from the rear. He also revealed to the Minamoto which ship the six-year-old Emperor Antoku was on. Their archers turned their attention to the helmsmen and rowers of the Emperor's ship, as well as the rest of their enemy's fleet, sending their ships out of control. Many of the Taira saw the battle turn against them and committed suicide.
