Would anyone have a photo or reference that showed the capture of a Mk.V tank by the German forces during the 1918 war on the Western Front? I have yet to find evidence of that.
I remember I read, probably in one of excellent Rainer Strasheim’s books, that the Germans never captured a Mark V. They had one chance but they didn’t realise that it was a new type thinking it’s just Mark IV and left it on a battlefield.
Hundleby & Strasheim „The German A7V Tank and the Captured British Mark IV Tanks of World War I”, page 163:
On July 23rd, 1918, a British Mark V tank was lost behind the German lines at Mailly-Raineval. But the German front-line commanders do not seem to have realised that this vehicle represented an entirely new breed, and no attempts were made to secure the tank. Thus, the only chance the Germans ever got to evaluate and test the new British tank was lost.
