The Winter War

The Winter War between the Soviet Union and Finland endured for 105 freezing cold days beginning in the year 1939 and ending in 1940.

Many saw the war as already been won by the Soviets before it even began, but what came as a surprise to many was that Finland was actually able to put up a respectable fight. There were several points of successful military strategy throughout the war that led to the signing of the Moscow Treaty. However, the Winter War resulted in more than just a treaty. The Finnish army was able to perpetrate an extremely large number of losses onto the Red Army; more than anyone would have ever imagined possible for a country as small in numbers as Finland. Thus, proving to Germany alongside other countries around the world that it was indeed possible to defeat the “undefeatable” Russian Bear. ;xNLx;;xNLx;[Click here to watch actual footage from the Winter War](
