When we seek an example of great leaders with unalloyed courage, the person who comes to mind is Winston Churchill: the iconic, visionary war leader immune from the consensus of the day, who stood firmly for his beliefs when everyone doubted him. But how did young Winston become Churchill? What gave him the strength to take on the superior force of Nazi Germany when bombs rained on London and so many others had caved? In Andrew Roberts gives readers the full and definitive Winston Churchill, from birth to lasting legacy, as personally revealing as it is compulsively readable. Roberts gained exclusive access to extensive new material: transcripts of War Cabinet meetings, diaries, letters and unpublished memoirs from Churchill's contemporaries. The Royal Family permitted Roberts—in a first for a Churchill biographer—to read the detailed notes taken by King George VI in his diary after his weekly meetings with Churchill during World War II. This treasure trove of access allows Roberts to understand the man in revelatory new ways, and to identify the hidden forces fueling Churchill's legendary drive. We think of Churchill as a hero who saved civilization from the evils of Nazism and warned of the grave crimes of Soviet communism, but Roberts's masterwork reveals that he has as much to teach us about the challenges leaders face today—and the fundamental values of courage, tenacity, leadership and moral conviction.
