Sunken Lane, Beaumont Hamel, Somme.
In the photo, men of the 1st Lancashire Fusiliers are about to go over the top.
Accurate German rifle and machine gun fire cut them down fire soon after.
Within a few minutes, the battalion lost more than half their strength with 163 killed, 312 wounded and 11 missing.
People called it the "war to end all wars" but it wasn't. Lest we forget.
