Soviets launch attack on Japan’s home islands
11 August 1945. In line with the Yalta Agreement but also as part of Soviet plans to invade Hokkaido, Soviet forces attack the Japanese colony of Karafuto (southern Sakhalin). Although outnumbered three to one, Japanese troops resist fiercely, disrupting Moscow’s overall strategy. The Soviet conquest of Karafuto is finally completed on the 25th.
