1. Naval Staff War Diary, June 18, 1940. Quoted in Ronald Wheatley, Operation Sea Lion, p. 16. The author, a member of the British team compiling an official history of the war, had unrestricted access to the captured German military, naval, air and diplomatic archives, a privilege not accorded up to the time of writing to any unofficial American authors by either the British or the American authorities, who hold joint custody of the documents. Wheatley, as a guide to restricted German sources on Sea Lion, is therefore very helpful.
