In retaliation for Qing China's refusal to pay compensation on the grounds that the Taiwanese aboriginals were out of their jurisdiction, Japan sent a military force to Taiwan, the Taiwan Expedition of 1874. The first overseas deployment of the Imperial Japanese Army and Imperial Japanese Navy saw 3,600 soldiers win at the Battle of Stone Gate on May 22. Thirty Taiwan tribesmen were either killed or mortally wounded in the battle. Japanese casualties counted 6 killed and 30 wounded.
