Battle of Miyajima

In 1551, Sue Harukata revolted against his lord Ōuchi Yoshitaka in the Tainei-ji incident, forcing him to commit seppuku. Sue installed the next lord of the clan, Ōuchi Yoshinaga (younger brother of Ōtomo Sōrin), but effectively led the Ōuchi family and its armies, intent on military expansion. In 1554, Mōri Motonari, as a vassal of the Ōuchi clan, wanted to avenge the betrayed Yoshitaka, and so he rebelled against Sue, whose territorial ambitions were depleting clan resources. The heavily outnumbered force under Mōri attacked and defeated Sue at the Battle of Oshikibata. Mōri then departed from the mainland to build a fort, known as Miyao Castle, on Miyajima while proclaiming publicly his woe that it would not hold out long against an attack. ==Battle==

Miyao Castle was built on a hill near Itsukushima Shrine and facing the mainland, making it a visible and tempting target. Sue commandeered a fleet of merchant vessels and prepared the troops of the Ōuchi clan to cross the channel. In the early hours of 15 October, Sue attacked Miyao Castle in an amphibious frontal assault. With an embarkation point secured, Mōri Motonari continued with his elaborate plan. He had enlisted the aid of the Noshima Murakami, a gang of local pirates led by Murakami Takeyoshi, who agreed to transport the Mōri troops to Miyajima. Sue Harukata escaped from the confines of Miyao Castle, but when he saw that escape from the island was not possible, he also committed suicide by seppuku. The Ōuchi clan's senior vassal Hironaka Takakane fought, together with his son, to the end, and he was also killed. ==Aftermath==

The Sue forces at Miyajima are estimated to have been about 20,000 to 30,000 men, and though estimates of the combined forces under Mōri Motonari range widely from 4,000 to 10,000 troops, it is clear that Mōri was heavily outnumbered. This victory brought the Mōri clan into a preeminent position in western Japan, and established their reputation for strategy and naval tactics. Immediately after the battle, Mōri Motonari ordered that the bodies of the fallen troops be removed to the mainland, and then ordered that the entire battlefield be cleansed of the blood that was spilled, to the point that buildings were scrubbed, and blood-soaked soil was removed from the island. The Mōri clan later funded several construction or renovation projects on the island. The remains of Sue Harukata were transported back to the mainland and positively identified at Sakurao Castle before being accorded a funeral and burial in the cemetery of a nearby Buddhist temple in present-day Hatsukaichi city, Hiroshima Prefecture. ==See also==
