Battle of Shumshu
Although Japan officially surrendered to the Allies on August 15, 1945, the Soviet Union hoped to occupy the Kuries Islands to extend their borders and before American occupation forces arrived in Japan. In accordance with the surrender, the Japanese garrison in the Kurlie islands had begun prepairing for disarmament.

On August 18, 1945 a Soviet force of 8,360 troops supported by naval and air forces made an amphibious landing on Shumshu. Forty Japanese tanks from the Japanese Army 11th Tank Regiment commanded by Col Zueo Ikeda attacked the Soviet landing force in "self-defense". During a vicious close-quarters battle in the fog that lasted more than two hours, the tanks claimed to have killed over 100 Soviets until their anti-tank guns were deployed and disabled twenty-one of their tanks. Two days later on August 20, a cease fire was signed and the Battle of Shumshu officially ended on August 23, 1945 with the surrender of the island's garrison, ending the last battle of World War II in the Pacific.

After the war, the Soviets removed the Japanese garrison who were now prisoners of war to labor camps, along with able bodied civilian men from the islands. Other civilians were deported back to Japan. In 1946, the island was officially annexed by the Soviet Union. Japan formally gave up sovereignty under the terms of the San Francisco Peace Treaty of 1951.

Since the war, the island was considered part of the Soviet Union (Russia). The wrecks of several transport ships still remain. There are many bomb craters in the area. Several dozen tanks from the August 18, 1945 battle remain in situ, including a Type 97 Chi-Ha Medium Tank.
