I sent some documents of his to be translated and received amongst the translated documents, the following information:
Partisan Document Identity Card (Post War)
Certificate No. 130961
Vishnevskii Pavel Filipovitch indeed took part in the Partisan movement in Belarus during the Great Patriotic War from 12. September 1943 to 22. July 1944 in the capacity of the Chief of Staff of the Minsk Communication Centre.
[Signed by] Representative of the Executive Committee of the Minsk region, 30 August 1972
This confirms his name and for me at least confirms my thoughts that he is the man mentioned who as a member of a plane crew was shot down, injured and joined the Partisans in Minsk.
My sincerest thanks to Giles and Eloise Penman, whose help has been greatly appreciated.
