It looks like the Somme, but I'm not too sure. Does anybody know who took it? and where and when it was taken? Thank you in advance for any help.

Tineye gives conflicting results, but the top result from getty images says it's from the Somme - credit Paul Popper (which seems to be the name of the agency rather than the actual photographer.)
