The exact identity of the "man who never was" has been the centre of controversy since the end of the war. On the one hand, certain accounts claim the true identity of "Major William Martin" was a homeless, alcoholic rat-catcher from Aberbargoed, Wales, Glyndwr Michael, who had died by self-administering a small dose of rat poison. However, in 2002, authors John and Noreen Steele published the non-fictional account of "The Secrets of HMS Dasher", about an ill-fated escort carrier that exploded and sank in the Firth of Clyde around the time Operation Mincemeat had commenced. The Steeles argued that "Major Martin's" body was actually that of seaman John Melville, one of the "Dasher's" casualties. Further, it has been reported that the accuracy of this claim was verified by the Royal Navy in late October 2004, and a memorial service was held for Melville, in which he was celebrated as one whose "memory lives on in the film "The Man Who Never Was"...we are gathered here today to remember John Melville as a man who most certainly was." But in fact, Professor Denis Smyth, a researcher at the University of Toronto, has counter-argued that Glyndwr Michael was indeed the real "Major Martin." To support his claims, Smyth published the contents of a secret memo and an official report, both authored by Ewen Montagu himself, confirming the Glyndwr Michael story.
