The Port Arthur massacre (Chinese: 旅順大屠殺) took place during the First Sino-Japanese War from 21 November 1894 for three days, when advance elements of the First Division of the Japanese Second Army under the command of General Yamaji Motoharu (1841–1897) killed somewhere between 2,600 civilians and 20,000 including Chinese soldiers in the Chinese coastal city of Port Arthur (now Lüshunkou District of Dalian, Liaoning).
