Finland's relationship was not really an alliance w/ Germany. Since Great britain and Sweden did nto come to the aid fo Finland in 1939 or 1944, Finland turned to germany out of necessity, and only because Germany was an obvious enemy of the Soviet Union.
My grandfather blew up 5 Russian tanks with molotov cocktails in the Winter War and my grandmother was a nurse in a Finnish field hospital. They had to move their MASH outposts repeatedly as the Russians would shell their tents.
Just like in The Cuckoo?
Great movie.
Though I question the real-life efficacy of blowing into a patient's ear while howling like a wolf.
