An amazing story of heroics. 50% of the aid ships going to Murmansk were sunk with 100% loss of the crews.
Still, with that knowledge, those crews volunteered to make that trip.
Soviet troops cried when they were given Spam because it was the first meat they'd eaten in two years. I've read that during the last two years of the war that Soviet troops 'marched' on Spam from the USA.
The Ruskskis may have gotten some Spam, but according to my WW2 vet pappy (may God rest his soul), it was mainly canned pork stew that was about half lard flavored with a single bay leaf. He received a can of this stuff after the war and opened it. He purchased it from a surplus store. The can had both English and Russian writing on it.
