Robert Kershaw’s excellent War Without Garlands

Kershaw has a masterpiece here, and this book will explain in graphic detail the difficulty faced by the Landser in a 6 month period, from the start of the invasion until the end of December of 1941 and early 1942.

Tired and exhausted from continual movement to support the Panzers as they encircled yet another number of Red Army Divisions, and without the infantry the pockets could not be collapsed. The trapped Soviets inside the circle would often charge forward in mass attacks in attempts to break out of this pocket, and their bodies piled up all around German machine gunners. Some would fight it out to the end and the result were companies depleted of both seasoned officers and NCO's from the brutal amount of resulting carnage.
It is a compelling tale of how the Wehrmacht far out ran its logistical reach & in the face of an enemy that just wouldn’t give up, victoried itself to death. Should you have any interest in learning more about Operation Barbarossa, can I heartily recommend this superb book to you
