Summary

Working for the Cypher Bureau of the Polish General Staff, and using only encrypted messages, mathematician Marian Rejewski and two colleagues reverse-engineered an Enigma machine and built a `cryptologic bomb' to translate messages written by it. Just before the German and Russian invasions of September 1939, the Poles passed this information to Britain and France, and it became the unacknowledged basis of code-breaking operations at Bletchley Park.
