Map of the battle
and an air view
This is where Chaser and Blitz were knocked out with no. 22 Cherry.
Note the location is Franqueville and reading John Gilbert's 'Bloddy Buron' I see he mentions there was some confusion as to where the engagement took place and he says it was more likely Franqueville than the commonly accepted Authie. He is correct.
Note that the POWs seen in my first post were located somewhere at the centre bottom of the above air view and thus must be survivors from the tanks being taken away.
