Fighter: The True Story of the Battle of Britain (ISBN 1845951069) is a Second World War military history book by English author Len Deighton. First published in 1977, it was Deighton's first history book although he had made his name as a writer of spy fiction. Deighton was encouraged to write the book by his friend, the British historian AJP Taylor, who wrote its introduction. The book covers the traditional period of the Battle of Britain and the buildup to it and describes the war in the air as much from the German point of view as the British one.
