Operation Milepost

'Milepost' was a US unrealised plan to increase its stocks of matériel, fuel and other supplies in the Far East (summer 1945).

The object was to support the Soviet forces when they entered the war against Japan on 8 August 1945 with the 'Avgust Buri' (more formally the 'Manchurian Strategic Offensive Operation') concentric offensive against the Japanese forces in Inner Mongolia and Manchukuo (Japanese-occupied Manchuria) by Marshal Sovetskogo Soyuza Aleksandr M. Vasilevsky’s Far East Direction, comprising Marshal Sovetskogo Soyuza Rodion Ya. Malinovsky’s Trans-Baikal Front (five armies), General Maksim A. Purkayev’s 2nd Far Eastern Front (two armies) and Marshal Sovetskogo Soyuza Kirill A. Meretskov’s 1st Far Eastern Front (four armies). The armies of these three fronts overran Inner Mongolia, Manchukuo and Korea as far south as the 38th parallel by 22 August, and also took the southern half of Sakhalin island and the Japanese end of the Kurile islands group.

In the event the Soviet forces had little need to call on the Americans for any type of support.
