The Germans recovered and repaired a significant number of tanks from Cambrai in 1917 but I've read various references to British crews in 1918 destroying, blowing up or otherwise disabling their tanks when forced to abandon them. This suggests that British tanks were now carrying some form of scutlling charge. Does anyone have any info on this?
The description for photo number E04927 at the AWM suggests that this Mk IV female tank may have been deliberately destroyed. If they used a scuttling charge, it was good one.
