[Milsurplus] HFDF Atlantic

[Hubert Miller]

Going thru my paper and moving out as much as i can part with. One of the Battle of Atlantic books listed TBS as something like #4 or #5 in this battle winnig weapons. First time i'd seen the TBS pointed out this way. BTW, Enigma decrypts, this book sez  HFDF as important, because decrypts sometimes  took hours, even sometimes days, whereas HFDF was realtime.
