Interesting book, perhaps? Masters and Commanders: How Roosevelt, Churchill, Marshall and Alanbrooke Won the War in the West by Andrew Roberts - The Sunday Times review - Times Online Who were the most important American and British military commanders during the second world war? Well, my guess is that most people would say General Dwight Eisenhower on the American side, and Field Marshal Bernard Montgomery on the British side. They are certainly the most famous. But, as Andrew Roberts shows us in Masters and Commanders, they were not the most important. It was Field Marshal Sir Alan Brooke (later Lord Alanbrooke) in London, and General George Marshall in Washington, who, along with their political masters, Winston Churchill and Franklin D Roosevelt, determined the strategy that the West needed in order to fight the war.
