This is probably the best account of the German side of Operation Market Garden in English. The author, a British Parachute regiment officer, used German sources while he was based in Germany to find out what happened from the other side of the hill. It is a fascinating account and dispels some of the myths about the battle, especially the controversy over whether there were really two full panzer divisions in the area when the Operation took place. He uses German ration returns and maintenance reports to show what was there for definite and uses his military knowledge to fill in the few gaps with reasonable guesses. In all he paints a different picture to the popular histories. If you are seriously interested in Market Garden then you must buy this book, it is an invaluable resource.
