Overview
The took place on 24 September 1877, in Kagoshima, Japan. It was the final battle of the Satsuma Rebellion, where the heavily outnumbered samurai under Saigō Takamori made their last stand against Imperial Japanese Army troops under the command of General Yamagata Aritomo and Admiral Kawamura Sumiyoshi. The battle culminated in the annihilation of Saigō and his army, marking the end of the Satsuma Rebellion. The Imperial Army's victory consolidated their power, and the Satsuma Rebellion was the last instance of internal mutiny seen in the Empire of Japan.
Battle
Following their defeat at the Siege of Kumamoto Castle and in other battles in central Kyūshū, the surviving remnants of the samurai forces loyal to Saigō Takamori fled back to Satsuma, seizing the hill of Shiroyama overlooking Kagoshima on 1 September 1877.
Imperial army troops under the command of General Yamagata Aritomo and marines under the command of Admiral Kawamura Sumiyoshi began arriving soon after, and the rebels were promptly surrounded. In the mere six months since Saigō's failed Siege of Kumamoto Castle, a combination of defections and combat losses had shrunk the size of his army from 20,000 to 500, compared to the Imperial Army's 30,000.
Yamagata, although greatly outnumbering Saigō, bided his time constructing a series of fortifications to encircle Saigō and prevent any chance of a breakout, additionally requisitioning five warships to bombard the rebels and reduce their defenses. He was planning an attack from all sides, and in an effort to prevent another escape, ordered that any position engaged by the enemy was to be fired upon, regardless of friendly casualties.
