WWII pigeon message stumps GCHQ decoders

The remains of the bird were found in a chimney in Surrey with a message from World War II attached.

Experts at the intelligence agency GCHQ have been struggling to decipher the message since they were provided with it a few weeks ago.

They say it may be impossible to decode it without more information – some of which could come from the public.

The message was discovered by David Martin when he was renovating the chimney of his house in Surrey.

Other than classes learning how to do it, I don’t think I ever cracked open the SOI* and actually composed a message.

Maybe Craig has an old one laying around and can crack this…

*SOI-Signal Operating Instructions- a combined “directory” or call signs, assigned frequencies, and code instructions for a given unit. Normally good for 30 days. Training SOIs are used over and over, but operational SOIs are replaced monthly.

  1. If the message was encoded using a one-time pad, the probability of decoding it approaches zero. Not a thing that the boys at Bletchley can do.
