Forged ''Cichociemni'' claims by others
, wrote in his 1971 autobiography For Those I Loved that he had participated in the raid on Pińsk prison. Doubt had been cast on a number of claims in the book, including whether he was a survivor of Treblinka, and when Kopisto was shown a wartime photograph of Gray in 1990, he said he had never met Gray during the war, nor had a man resembling the photograph of him ever belonged to their unit:
For the first time in my life I saw Martin Gray in a 1945 photo, which was published in March 1990 in Przekrój magazine... There were only sixteen of us participating in the 1943 Pińsk raid, and he was not among us.
