An excellent compilation of various battlegroups (Kampfgruppe) during various phases and fronts during WWII. This is a must for the military enthusiast and would be very useful for wargamers. My only critisism is that I wish there were more chapters!! A very good read. The book relates the operations of 17 different specific battlegroups, including operations in Poland, France, many in Russia and later again on the eastern front as the war was brought right through the Ukraine, Hungary, Poland and Prussia. There is a chapter devoted to a Hitler Youth unit operating in France in 1944. One of the most interesting chapters relates the creation of a Kampfgruppe that was to operate in England during operation "Sealion". Highly recommended.
