The Winter War
The Winter War was a military conflict between the Soviet Union and Finland.
The Winter War was a military conflict between the Soviet Union (USSR) and Finland. It began with a Soviet invasion of Finland on 30 November 1939, three months after the outbreak of World War II, and ended three and a half months later with the Moscow Peace Treaty on 13 March 1940. The League of Nations deemed the attack illegal and expelled the Soviet Union from the organisation.
The conflict began after the Soviets sought to obtain parts of Finnish territory, demanding among other concessions that Finland cede substantial border territories in exchange for land elsewhere, claiming security reasons—primarily the protection of Leningrad, 32 km (20 mi) from the Finnish border. Finland refused, and the USSR invaded the country. Many sources conclude that the Soviet Union had intended to conquer all Finland, and use the establishment of the puppet Finnish Communist government and the Molotov–Ribbentrop Pact’s secret protocols as evidence of this,[F 8] while other sources argue against the idea of the full Soviet conquest.Finland repelled Soviet attacks for more than two months and inflicted substantial losses on the invaders while temperatures ranged as low as −43 °C (−45 °F). After the Soviet military reorganised and adopted different tactics, they renewed their offensive in February and overcame Finnish defenses.
Hostilities ceased in March 1940 with the signing of the Moscow Peace Treaty. Finland ceded territory representing 11 percent of its land area and 30 percent of its economy to the Soviet Union. Soviet losses were heavy, and the country’s international reputation suffered. Soviet gains exceeded their pre-war demands and the USSR received substantial territory along Lake Ladoga and in Northern Finland. Finland retained its sovereignty and enhanced its international reputation. The poor performance of the Red Army encouraged Adolf Hitler to think that an attack on the Soviet Union would be successful and confirmed negative Western opinions of the Soviet military. After 15 months of Interim Peace, in June 1941, Nazi Germany commenced Operation Barbarossa and the Continuation War between Finland and the USSR began.
