Re: Code-Breakers:Bletchley Park's Lost Heroes
The Lorenz SZ42? Bill Tutte's heroic solo effort with two messages to work out the logical function of the machine, then Flowers at the GPO Dollis Hill championing Collossus?
It was only when Kesselring's comms convoy was intercepted and an SZ42 was brought to BP that Tutte, Flowers etc saw a machine in the flesh, as it were.
