I would recommend to you that you pay a visit to iTunes and download episode 27 of Dan Carlin's Hardcore History, which is the first episode of his "Ghosts of the Ostfront" series. The opening monologue is insanely captivating as he talks about the human remains still to be found today on the Russian steppe and how, in a very real sense it's a "good" thing so many ordinary Germans, who weren't different from anyone else, died and were stopped at Stalingrad, and that the bone fields serve as a monument to the misery that just one person is capable of realizing if he attains power. It's free and was mesmerising when I heard it some weeks ago.
