This article looked at the Unggi and Rajin Amphibious operations of the Soviet Navy's Pacific Fleet in August 1945. As the Allied Forces won World War II, Korea was liberated. The Soviet Army declared war on Japan on August 8, 1945 and participated in the second world war. The Soviet ground forces attacked Manchuria and defeated the Japanese Kwandong Army. And as a subsequent operation, they advanced to the northern part of the Korean Peninsula. The Pacific Fleet occupied ports in the North Korean region, with the aim of preventing the retreat and reinforcement of Japanese Kwandong forces.
Air units belonging to the Pacific Fleet bombed the Japanese naval bases in Unggi, Rajin and Chongjin on August 9 and 10, 1945. The Pacific Fleet attacked Unggi on August 11, 1945. Operation Unggi was carried out by the Fleet Command's reconnaissance units and marines. And on the 12th, the landing force occupied Unggi Port and Unggi City without much resistance.
The operation to Rajin began on August 12. Also, the Fleet Command's reconnaissance unit and marines were in charge of the operation.

Subsequently, while occupying Ungisi and the outlying hills, they attacked the Japanese forces and cleared out the Japanese forces in Daechodo and Sochodo.
