What was the Soviet 1945 invasion of Japanese-held Manchuria commonly called?

The Soviet 1945 invasion of Japanese-held Manchuria was commonly called Operation August Storm.

The operation began on 9 August 1945, when Soviet forces attacked the Japanese puppet state of Manchukuo from several directions. The offensive involved the Transbaikal Front, the 1st Far Eastern Front, and the 2nd Far Eastern Front, supported by the Mongolian People’s Republic. Soviet troops advanced rapidly through difficult terrain and defeated much of Japan’s Kwantung Army.

“Operation August Storm” is a later name popularized by American military historian David Glantz. Soviet sources more often used the term Manchurian Strategic Offensive Operation. The two labels refer to the same central campaign, although the wider Soviet–Japanese War also included operations in southern Sakhalin and the Kuril Islands.

The offensive intensified the crisis facing Japan’s leaders. Along with the atomic bombings and the growing prospect of invasion, Soviet entry eliminated Tokyo’s hope that Moscow might mediate a more favorable peace.
