 Rejewski maintained a lively correspondence with his wartime French host, General Gustave Bertrand, and at the General's bidding he began translating Bertrand's Enigma into Polish. In 1976, at the request of the Józef Piłsudski Institute of America, Rejewski broke enciphered correspondence of Józef Piłsudski and his fellow Polish Socialist conspirators from 1904. On 12 August 1978 he received from a grateful Polish people the Officer's Cross of the Order of Polonia Restituta.
