Midget submarine commander: the life of Rear Admiral Godfrey Place ... 19 July 1921-27 December 1994 /Paul Watkins.

Of all the acts of gallantry in World War II few were as audacious as the attack by midget submarines on the pride of the German fleet, the battleship Tirpitz. Lieutenant Place was in command of submarine X7 in September 1943 and travelled over 1000 miles, negotiating minefields and antisubmarine nets to accurately place four tons of high explosive under the hull of the Tirpitz. Using many first-hand accounts, the book details his life.
