Battle of Tabaruzaka

The Battle of Tabaruzaka was a major battle of the Satsuma Rebellion. It took place in March 1877, on the island of Kyushu, Japan, concurrently to the Siege of Kumamoto Castle.

Summary
The Battle of Tabaruzaka began on March 3, 1877 when troops loyal to the Imperial Meiji government seeking to break the Siege of Kumamoto Castle met rebel Satsuma samurai forces seeking to capture the main road out of Kumamoto. The battle eventually spread across a 6.5 mile line from Tabaruzaka to the Ariake Sea.

Skirmishes occurred for the first several days of the battle, as both sides continued to bring additional support troops to the area. In the end, Saigō's forces would number 15,000, and the Imperial Japanese Army, led by Arisugawa Taruhito and Yamagata Aritomo, numbered 90,000. The first days of the battle were marked by heavy rain, which hampered the rebel's ability to resupply. As a result of low ammunition supplies, and water damage to their antiquated muzzle-loading rifles, the rebel forces were forced to fight with swords. On March 15, the government forces launched a major assault on the rebel lines. On March 20, the rebels were forced to retreat, initially regrouping at Ueki, and then were driven from that position as well.

Final losses at Tabaruzaka were at least 4,000 dead and wounded on both sides.

Aftermath
Although the Siege of Kumamoto Castle did not end for several weeks after the Battle of Tabaruzaka, and the war lasted until September, this battle showed that eventually the government's superiority in men and material would ultimately overwhelm the rebel forces.
