Misty day. Worked hard on trenches. 5 men of āCā Coy when searching in front of our Trenches found an unexploded aerial torpedo & carried it back to a dugout but someone interfered with it & it exploded killing 5 men who were there. Relieved at 8 pm by 2nd Monmouthshire Regt & Battalion marched to VARENNES. Fine. Quiet relief.
