Talvisksi
Talvisksi, also known as the Winter War, was a military conflict fought between the Soviet Union and Finland from November 30, 1939, to March 13, 1940. The war was a result of the Molotov-Ribbentrop Pact, a non-aggression pact between Nazi Germany and the Soviet Union, which divided Eastern Europe into spheres of influence. Finland, which had remained neutral during the early stages of World War II, was invaded by the Soviet Union on November 30, 1939. The Soviet Union's primary objective was to gain access to Finland's ports on the Baltic Sea, which would have allowed it to bypass the Finnish-controlled Gulf of Finland and gain a direct route to the Atlantic Ocean.
The Finnish military, despite being outnumbered and outgunned, managed to hold out against the Soviet forces
The war ended on March 13, 1940, when the Soviet Union and Finland signed the Moscow Peace
