Shortcomings in the earliest reports coming from the wartime work at Bletchley Park resulted in a slightly distorted picture of the early inter-Allied cooperation in cryptology. The ultimate evidence of the Polish contribution to the success over Enigma, a report passed on to the British and French participants of the meeting in Pyry in July 1939, remains unavailable to historians. Some files declassified in 2015 by the French intelligence service contain a document representing most probably an abridged and rewritten version of the Pyry report. This paper offers a preliminary analysis of this document.
