Winter War

description Winter War Overview

The Winter War began on 30 November 1939 when the Soviet Union invaded Finland following Finland's refusal to cede territory demanded by Stalin. Finnish forces, though vastly outnumbered, used guerrilla tactics, superior winter mobility, and the Mannerheim Line to resist the Red Army for over three months. The war ended with the Moscow Peace Treaty on 12 March 1940, under which Finland ceded approximately 11% of its territory to the Soviet Union. The conflict exposed serious weaknesses in the Soviet military.

help Winter War FAQ

Why did the Soviet Union invade Finland in the Winter War?

The Soviet government demanded territory and security concessions intended to move the border farther from Leningrad. After negotiations failed, Soviet forces invaded Finland on November 30, 1939.

How did Finland resist a much larger Red Army?

Finnish forces used skis, camouflage, dispersed units, and intimate knowledge of forests and frozen terrain. Motti tactics isolated sections of Soviet columns, particularly along narrow roads where armored strength was difficult to exploit.

What was the Mannerheim Line?

It was Finland's defensive system across the Karelian Isthmus, named after commander Carl Gustaf Emil Mannerheim. It was less elaborate than France's Maginot Line, but terrain, field fortifications, and determined defenders delayed Soviet advances.

How did the Winter War end?

The Moscow Peace Treaty ended the fighting in March 1940. Finland remained independent but ceded substantial territory, including parts of Karelia, and later fought the Soviet Union again in the Continuation War.
