Four million Finns fight 168 million Soviets, and Hitler draws the wrong lesson
What happened
On 30 November 1939, Soviet guns opened fire and the Red Army invaded Finland, a war historian Robert Citino sums up as one of 168 million versus 4 million. It did not go as Stalin planned. Finnish ski troops, gliding out of the forests in white parkas, surrounded road-bound Soviet columns and left them to starve and freeze in pockets the Finns called motti, bundles of firewood to be collected later. At Suomussalmi, a reinforced brigade of Finnish Home Guardsmen ambushed and largely destroyed two entire Soviet divisions, the 44th and 163rd. One sniper, Simo Häyhä, was credited with 505 kills; the Russians nicknamed him White Death. Only on 1 February 1940 did a mass Soviet artillery assault begin cracking the Mannerheim Line, and after roughly 30,000 casualties of their own the Finns had no choice but to ask for terms.
Why it matters
Finland lost the Karelian Isthmus and about 11 percent of its territory, but the ferocity of its resistance likely made the difference between losing border provinces and being annexed outright. The larger consequence landed in Berlin: the Red Army had needed over three months and several hundred thousand casualties to defeat a neighbor a fraction of its size, largely because Stalin's own purges had removed 80 percent of its corps and divisional commanders, and Hitler's General Staff studied that performance and pictured a pushover, a misreading that became one of the planning assumptions behind the invasion of the Soviet Union eighteen months later.
How we know
Military historian Robert Citino, PhD, of the National WWII Museum, names the destroyed Soviet formations at Suomussalmi, the specific date the Mannerheim Line finally cracked, and the purge figures behind the Red Army's early failures; Finland's territorial losses are recorded in the terms of the Treaty of Moscow that ended the war.
