, 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.

At dawn, Takakage and his 1,500 troops landed before the small fortress, and the sound of shell trumpets signaled that all units were in position and the attack commenced. As Takakage's force rushed the front gate of Miyao Castle, Mōri and his troops hit the Ōuchi position from behind. Caught completely by surprise, many of the Ōuchi troops scattered in disarray. Hundreds tried to swim to the mainland and drowned in the attempt. Many more saw that defeat was inevitable and committed '']seppuku

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
