This study of war skillfully clarifies the complexities of four major World War II military campaigns: El Alamein, Monte Cassino (Italy), Operation Market Garden (of which Arnhem formed a crucial part), and the Battle of Britain (the RAF's bomber offensive against Germany). The book originates in Holmes's conviction that the sacrifices made by British service personnel are not properly understood. It uses eye-witness accounts to illuminate the horror, confusion and sheer enormity of war, and puts this in the wider context of the conflict's broader strategy. As the 20th century, so deeply marked by war, slips away, this is the time to recognize the price that so many of its men and women paid for freedom.
