Query: One of the greatest biographies ever written

A great biography of a great man! I couldn't put this book down and was sad to have it end. What a life Churchhill led. What would the West have done without his leadership. I am so sad that William Manchester could not finish this trilogy as he is one of the finest biographers I have ever read. His biography on MacArthur was fabulous also
