Britain's bestselling historian's account of the classic WW2 folly. Antony Beevor using many overlooked and new sources from Dutch, British, American, Polish and German archives, has reconstructed the terrible reality of this epic clash. Yet this book, written in Beevor's inimitable and gripping narrative style, is about much more than a single dramatic battle. It looks into the very heart of war. The Sunday Times No 1 Bestseller.
