General Heinrici is not a well-know German commander of WWII, at least in terms of others such as Rommel, but he was a very able officer. He was a professional soldier who commanded a Corps during the first two years of the War on the Eastern Front. He therefore provides a very valuable insight into the German invasion of the Soviet Union, the initial lightning successes, the first shock of a Russian winter and the blunting of the German thrusts in a vast territory. The author/editor has made a selection of the General’s papers and diary records that provide a very candid insight into the war on that front, together with Hurter’s perceptive introduction. A fascinating view and rewarding for the reader.
