This is THE definitive history of I SS Panzer Corps. Reynolds has written two books leading up to this (The Devil's Adjutant and Steel Inferno) which covered small areas of the I SS Panzer Corps history.
This current book covers it's inception, rise to full power and potency in June 1944 and it's subsequent crushing in Normandy. The rebuilding of it ready for the Ardennes offensive and it's role in that offensive. The third and final rebuilding ready for fighting the Russians in Hungary, and finally the death by a thousand cuts until the end of the war.
Covering the story of a Corps is a difficult task as the composition of the Corps varies as units are attached or taken away. Reynolds skill is to include all the comings and goings, and yet to pull it all together into one coherent thread, and to make it very readable. Reynolds also weaves in teresting asides into the story, such as the flow of supplies, and how the rebuilding took place. The only real criticism of the book is the maps, which are plentiful in places and non-existent in others, and can be misleading.
This is a fascinating and well written account of I SS Panzer Corps. It is a "must" for all Panzer freaks. I cannot wait for Reynolds next book.
