Hi,
So what are good books about this historic clash?
Here are two examples:
Hitler Move East (1941-1943) by Paul Carell
This book cover the war on the Eastern front from 1941 (Barbarossa) to 1943 (end of the Stalingrad battle)
Scorched Earth (1943-1944) by Paul Carell
From the start of 1943 up to the East Prussian frontier in 1944.
Those 2 books, totalling over 1300 pages, are one of the best account of this front. From the big plans on paper to the execution in the field. From the German and the Russian side. The mistakes, the fate of fortune, the bad luck. A lot of soldiers stories.
Absolute blast to read. If you can find them, buy them
