大山巌
On 19 February 1877, the Kumamoto Castle was attacked by around 20,000 samurai from the Satsuma Domain. True to his principles of the police working together with the military, Kawaji in his capacity as a major general led the Third Brigade, accompanying Major General Ōyama Iwao of the Imperial Japanese Army, who led the Fifth Brigade. Similar to Kawaji, Ōyama had also visited France to study. By 23 June, Kawaji, this time promoted as lieutenant general, and his division, had already entered Kagoshima, Saigō's headquarters (around 170 kilometers south of Kumamoto), reinforcing the beleaguered Admiral Kawamura Sumiyoshi and breaking the rebel strength. Saigō and his remaining forces, numbering around 500, were ultimately vanquished at the Battle of Shiroyama on 24 September 1877.
