 It is sometimes referred to archaically in Western sources as the "Battle of Ping-yang".Between 13,000 and 15,000 Chinese troops of the Beiyang Army under overall command of General Ye Zhichao had arrived in Pyongyang on 4 August 1894, and had made extensive repairs to its ancient city walls, feeling itself secure in its superior numbers and in the strength of the defenses.Prince Yamagata Aritomo's First Army of the Imperial Japanese Army converged on Pyongyang from several directions on 15 September 1894, and in the morning made a direct attack on the north and southeast corners of the walled city under very little cover.
