Hello,
In addition this NARA POW page (
http://aad.archives.gov/aad/display-...&mtch=328&pg=1 ) will show the POWs of 19th July 1944, some 33 pages ten on a page.
several died as POWs and at least three perhaps executed.
BUT your man may not even have been a POW he may well pre being killed, have been an evader .
Alex
