It began when the Soviet Union invaded Finland soon after the invasion of Poland. The Soviet military forces expected a victory over Finland in a few weeks because the Soviet Army had many more troops, tanks and planes than the Finnish Army.

However, the Finnish forces resisted better and much longer than expected. They had good winter clothes and wore white coats, which camouflaged them in the snow. As well, the Finnish soldiers moved around on skis, which made it easy for them to sneak up on the Soviet soldiers. The Soviets did not have good winter clothes, and they wore dark green coats, which were easy to see in the snow.

The peace treaty that ended the war in March 1940 left the Finns as a free people.
