Khalkhin Gol

11 May–16 September 1939

Two riverbanks in July, isolated pockets in August

Military history

How did the central fixing attack and outflanking wings isolate Japanese positions despite tenacious resistance?

In May 1939, a clash in a disputed border strip escalated into conflict between Japan and Soviet-Mongolian forces. In early July, Japanese infantry crossed the Khalkhin Gol at Bain-Tsagan while Yasuoka attacked on the east bank. Both efforts failed. Zhukov then prepared an offensive supported by supply arrangements organized with Shtern. On 20 August, the center fixed the defenders while armor outflanked them mainly in the south; the northern wing struggled at Hill 721. The encirclement broke up the Japanese force, though some survivors escaped.

Two claimed borders

Japan and Manchukuo placed the border on the river; the Soviet Union and Mongolia placed it near Nomonhan, about twenty kilometers to the east. The May incidents occurred in this interval. The Japanese telegram of 12–13 May describes an incursion according to Japan’s own claim, not a border recognized by both sides.

The July failure

Japanese infantry crossed to the west bank on the night of 2 July. The Soviet counterattack committed armor, at times without infantry support, and incurred heavy losses; the Japanese had a single pontoon bridge that could not sustain the necessary supply flow. The return east was complete by the 5th. Yasuoka also failed to drive the Soviets from the east bank.

Trucks behind the pincer

After Japanese attacks on 23–25 July, the battle stalled. The Soviets accumulated men, tanks, ammunition and fuel along a road hundreds of kilometers from the railhead. Zhukov commanded the maneuver; Shtern helped organize support. Japan’s underestimation of this logistical capacity contributed to the surprise in August.
