The book is Blood Red Snow: The Memoirs of a German Soldier on the Eastern Front by Gunter K. Koschorrek.
Saw this title while checking another in recent months. The book is very anti-war in tone.
The brief synopis from Amazon reads:
“This memoir is the first-person account of a German soldier who served on the eastern front during World War II. The author is not concerned with examining the reasons for the war or the tactics used to fight it. Rather, he sets out to present the day-to-day realities of the German soldiers by naming them and then relating their fates, which too often was violent death. Many of Koschorrek’s compatriots were run over by Soviet tanks or blown to pieces by Soviet shells.”
Koschorrek’s book is very much like Tigers In The Mud, one man’s personal diary of events during the war. The diary is quite detailed, and you can quickly see how overwhelming the Soviet army was, and how the Germans had bitten-off more than they could chew.
