The U.S. Navy was at war in the Atlantic long before 7 December 1941, but little is known about that conflict. "Mr. Roosevelt s Navy" is a vivid, thoroughly researched account of this undeclared war upon which Franklin Roosevelt embarked in order to sway the desperate Battle of the Atlantic in favor of Britain s hard-pressed Royal Navy. Not only is this book a history of the U.S. Navy s Atlantic Fleet and its impact on German-American strategy and diplomacy prior to and immediately following American entry into World War II, but it is also a lively account of the muted battles and endless patrols that were the pattern of life for American sailors in the cold, gray Atlantic. First published in 1975, the book is now available in paperback."
