A detailed and very technical look at the attempt by Germany to relieve the trapped 6th Army at Stalingrad in December 1942. Contains translated orders, radio messages, and the author’s (a tank commander) explanations of the operations. Also includes sixteen detailed maps covering each phase of the attempt. The author believes the plan, called Operation Thunderstorm, ultimately failed because General Paulus’ refused to disobey Hitler and order his trapped army to fight its way backwards to meet the relievers. But this is not a strategic book; rather it is useful to understand the challenges faced by an already under-strength and out-gunned army in a mission with almost no chance of success from the beginning.
