Soviet forces enter Korea
11 August 1945. An amphibious force of naval infantry storms ashore at Yuki (Korean: Unggi) near the Soviet–Korean border. The port falls on the next day after Soviet land forces arrive. Two days later, an amphibious assault on the major port of Seisin (Ch’ŏngjin) meets fierce Japanese resistance. The eventual fall of Seisin on the 16th totally disrupts Japanese sea and ground communications with the Kwantung army in Manchuria.
