A friend of mine bought a group of documents of a German tanker of WW1. Believe it or not ... he now owns an award certificate of the German "Erinnerungsabzeichen fuer Kampfwagenbesatzungen" (Badge for tankers WW1).
He now is looking for further information regarding Lt. Geyer. It seems that he was a tank crew member in tank detachment no. 11.
My name is Victor Kushmaniuk and I'm producing a television documentary about Great War tank battles. Unfortunately I cannot help you with your search, but your interest in this subject has motivated me to ask you for help!
I'm looking for first hand accounts from men who served in tanks (memoirs, diaries, interviews) on both sides. In particular, I'm having some challenges finding German accounts (either by infantry or by tankers) of what it was like seeing tanks for the first time, what it was like fighting tanks and ultimately - what it was like fighting in tanks (again, especially from the German perspective). If you can offer any suggestions, I would greatly appreciate it.
