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, Fighter was Deighton's first history book, he having made his name as a writer of spy fiction. Deighton was encouraged to write the book by his friend, the British historian A.J.P. Taylor, who wrote the introduction to Fighter. Fighter covers the traditional period of the Battle of Britain and the build-up to it, describing the war in the air as much from the German point of view as the British.
