The Germans did not lose 500,000 men at stalingrad. Check your sources. But the Russians did lose a million out of incomeptence and their own Brutality towards their own men. Official Soviet records show that 15000 men were executed for "cowardice" at Stalingrad. Given that Soviet stats are almost always lies I would multiply that by ten. The number of those encicled was about 250,000. By the time of Surrender 90'000 or so Germans and Rumanians went into captivity. 3 to 6 thousand returned decades later alive. Lovely.

Yeah, that's why by Paulus' own records there were 300,000 men in the encirclement and no one got out...and that's after Uranus and Naptune kicked off, not counting battle losses up to it. Do some research...read Enemy at the Gates or Stalingrad by Ballentine press. Get informed.
