In 1939, Stalin’s Soviet Union invaded Finland expecting a quick and easy victory. Instead, the Red Army found itself trapped in a frozen nightmare of forests, snow, ambushes, and fierce national resistance. This episode explores how Finland, vastly outnumbered and outgunned, used terrain, morale, ski troops, defensive strategy, and the brutal northern winter to humiliate one of the largest armies in the world. From the Mannerheim Line to the famous motti tactics, from Stalin’s military purges to Finland’s fight for survival, this is the story of how a small nation forced an empire to pay a shocking price.
