Winston Churchill was the greatest war leader Britain ever had. In 1940, the nation rallied behind him in an extraordinary fashion. But thereafter, argues Max Hastings, there was a deep divide between what Churchill wanted from the British people and their army, and what they were capable of delivering. Himself a hero, he expected others to show themselves heroes also, and was often disappointed. It is little understood how low his popularity fell in 1942, amid an unbroken succession of battlefield defeats. Some of his closest colleagues joined a clamour for him to abandon his role directing the war machine. Hastings paints a wonderfully vivid image of the Prime Minister in triumph and tragedy. He describes the ‘second Dunkirk’ in 1940, when Churchill’s impulsiveness threatened to lose Britain almost as many troops in north-west France as had been saved from the beaches; his wooing of the Americans, and struggles with the Russians. British wartime unity was increasingly tarnished by workers’ unrest, with many strikes in mines and key industries.
