1939 Soviet-Finnish War

The 1939 Soviet-Finnish War, known as the Winter War, occurred when the Soviet Union invaded Finland in November 1939, shortly after World War II began. The USSR aimed to secure territory and strategic positions, but Finland fiercely resisted with well-trained troops and effective tactics, despite being outnumbered. The harsh winter conditions and Finnish defenses made progress difficult for the Soviets. The conflict resulted in Finland ceding some territory but maintaining its independence, with the war highlighting the resilience of Finnish forces and exposing weaknesses in Soviet military planning. The war ended in March 1940 with the Moscow Peace Treaty.
