HMS Seraph

The HMS Seraph, upon which Rear Admiral Sir David Scott (from the Ferdinand the Submariner Bull post) served was a storied British naval vessel not only as an attack submarine but also for its various secret missions. Among these was the famous Operation Mincemeat by which the British successfully misdirected the Germans regarding their war aims. Ewen Montagu wrote a popular account of the mission in 1954, The Man Who Never Was, which is usually still available in libraries and is a good WWII action read for seventh grade readers and above, akin to Thirty Seconds Over Tokyo and God Is My Co-Pilot.
