On 1 August 1886 (
Meiji 19), the
Qing dynasty's
Beiyang Fleet, consisting of four warships, the
Dingyuan, the
Zhenyuan, the
Jiyuan, and
Weiyuan, entered the Nagasaki harbor port during a visit to various major Asian harbours. At that time, Qing China was militarily superior to
Meiji Japan. The
Dingyuan had more tonnage than the heaviest Japanese cruisers in service, due to Japan's policy of following the
Jeune École naval strategy, which emphasized small rapid assault craft. In addition, Japan had recently suffered setbacks in the
Kapsin Coup in which around 400 Japanese troops stationed in
Joseon Korea were defeated by nearly 2,000 Qing-Joseon soldiers. On August 13, around 500 Chinese troops went on shore leave, with many visiting the
red-light district, leading to altercations with locals. The resulting property damages was blamed on the soldiers. Locals also claimed that drunken Chinese soldiers went around the city pursuing women and children much to public outrage. The Nagasaki Prefecture Police Department attempted to restore order with the help of a large number of local civilians. The policemen engaged in several hand-to-hand battles with the Chinese sailors who used swords purchased from stores; the melees resulted in at least 80 deaths. A sense of unrest subsequently pervaded across the city. On August 14, at a conference between the governor of Nagasaki prefecture Kusaka Yoshio and the Qing consulate Xuan Cai, the Qing navy prohibited its soldiers from going ashore as a group for one day and agreed to have their troops supervised by officers when on shore leave. On August 15, at around 1:00 PM, following the cessation of the agreement, about 300 Qing troops went ashore; some were armed with clubs. A group of Qing sailors attacked three police officers, resulting in one death. A driver of a
rickshaw (
jinrikisha) witnessed the scuffle and, in indignation, tried to punch one of the Qing troops. In response, the Qing sailors rioted. The Nagasaki police responded and again fought with the Qing sailors, resulting in more casualties. On the Qing side, 4 were killed (1 officer and 3 soldiers) and 53 were injured (3 officers and 50 soldiers). On the Japanese side, 2 constables were killed with 3 police officers injured along with 16 more. Several tens of Japanese civilians were also injured. ==Aftermath==
