Back in USSR time in school history they never mentioned lend lease at all... According to them the great ppl of USSR won the war, everything else was so insignificant scale that not worth mentioning. So maybe many Canadians lost their lives in vain delivering this aid? I don't think so. Facts tell the help was important and significant. Not to mention economic war and blockade that cut Nazi Germany from supply. Whose military and merchant navy did this? USSR?
Quote from another forum:
40% of the aviation gasoline USSR used
37% of the rails for the Soviet reilroads
64% of all vehicles
55% of all aluminum
45% of all copper
30% of all automobile tires
30% of all sugar
24% of all machining equipment
and so on
As for so on - I can tell that even leather, wool, boot, buttons were supplied too.
And also don't forget that quality of these cars, tanks, planes and machinery was way above what USSR was able to produce.
Here is this diagram. Percentage of lend lease to the same products made in USSR. From left to right: Tanks, SPGs, planes, cannons and mortars, ships, cars and trucks, small arms, car gasoline, airplane gasoline, railways, trains, explosives, aluminum, copper, car tires, sugar, cotton, machinery.
