If you read Enemy At The Gates: The Battle for Stalingrad by W. Craig, the closing chapters discuss what happened to the Germans at the tail end of their Eastward Campaigns, and also discussed the Russian side of the battle. Also just a really good book for showing the horrors of war. The number of lives lost was absolutely crazy, and plenty of POWs were taken that were executed, starved, or died of many other causes after their capture due to brutal mistreatment. More senior officers were kept alive and turned into propaganda pieces by the Russians.
