The technique was later used by the United States on the Western front ~ friend of mine who'd been in the Germany Army as a 15 year old said you had to see it to believe it. From his vantage point in the bottom of a ditch he said the Americans had as many artillery pieces as the Germans had rifles.
The Finns also had the advantage of playing on the home ground, properly dressed, equipped with skis, and later on there were as many as 180,000 German troops on hand (doing lord only knows what).
As part of the "terms" for the cease fire Stalin demanded half of Finland ~ which he got ~ and he wanted the Germans kicked out of Finland ~ which he also got. They were booted North to enter Norway in the Winter .
Still, after defeating both Russia and Germany, Finland survived.
It took the Allies another 50 years to accomplish both tasks!
Thanks for pointing this out.
The major reason to Finland’s defeat of the Soviets in that war was them being a well prepared, patriotic, well organized nation.
Swedish support played a role, but their victory truly belongs to them and no one else.
