From a military point of view of course, this aspect being generally known, the preparations, the early hours of 22 June 1941, devastating for the Red Army, the brilliance of the German advance, the great battles of encirclement, the pushed Ukraine, Typhon, the attack against the Soviet Rzhev, Fall Blau, Kursk, Bagration, Cherkassy-Korsun, the Calvary of Warsaw to the Berlin suburbs reduced to a heap of ruins ...
But also from a diplomatic point of view, human, through personalities Vojd and his alter-ego Hitler, policy (including differences between the two "systems"), economic (the importance of using Channel American is described very precisely for example), naturally the criminal and barbaric aspect is also mentioned with the logic of ruthless extermination proven by the Nazi occupiers and sinister Einsatzgruppen.
Many figures, a ventilated text with a book that reads very well, we almost start from the end of the First World War finally at the threshold of the Cold War, with the innumerable footnotes page that characterize the author, even a bibliography extremely provided in a word-reference in a book for me, a key period, the consequences of this confrontation being felt long after the fall of Berlin in May 1945.
At most, we can regret the (relative) lack of a map provided slightly more generally I recommend (highly) this manuscript to anyone interested from near and far to this troubled but exciting period of our History.
