248 pages, with a foreword by Rear-Admiral B.W Taylor, and 23 plates in half-tone and 12 diagrams by the author. Blue boards with faded gilt print on spine. A clean, unmarked and solid copy." Includes 'the first escape ever'; Thetis, Squalus; rescue bells, escape apparatus. A very interesting book. The first half of the book describes successful escapes from sunken submarines from early periods, one as early as the 1850's. The second half is the author's personal experiences of pioneering many methods of submarine escape from 1941 when he was appointed to command the Royal Navy's Submarine Escape Training Unit. All types of submarine escape apparatus known up to that date are also described with detailed drawings." (Classic Dive Books)
