Mysteries of P.C. Cadix and its evacuation in 1942/43

Abstract

From 1940 to 1942 a group of Polish codebreakers, authors of the initial Enigma breakthrough, had been working at the P.C. Cadix, a secret codebreaking center situated in the unoccupied France. Their work in this period, and in particular the circumstances of their evacuation after the German/Italian occupation of Vichy France, are shrouded in mystery. This paper represents an attempt to put information known so far into a broader context, revealing in the process possible distortions and omissions in the accounts of the participants of the events.
