I am looking for photos of General Maj. Nikolaus von Schemmel and Oberst Freiherr Paul von Troschke, who were commanders of Oflag VII A. Schemmel later became commander of POW in WK XIII, von Troschke ended his career and, by his own choices, his life in 1944. There is little Information on them available, as their main "careers" happened during WW1.

Any help would be very much appreciated.
