Ron Brelsford sent a note to Dave D'Auria, the NCMF's Acquisitons Chairman, that noted: "As an appendix to my volunteer work in the Military Intelligence Service technical collection, I got hold of 50 unsolved German Enigma-messages, recovered a number of years ago from a German U-boat, sunk in Danish waters in the last days of WW2. At a conference in Germany in June for crypto historians I met a young German engineer who had tried in vain to solve old Enigma messages. He succeeded in solving almost all of mine, with a little help from me and an American Enigma-fan. That was a lot of fun, a lot of work, and a bit of a sensation. Anyone interested can find more on his website, Breaking German Navy Ciphers."
