From the war diaries of the 14th Bn RWF.
From date and place of burial, Pte Pocock probably died in this action:
Jun 4 1916 At 10.45pm a strong raiding party under Capt. H P Williams Lieut. A Lloyd Jones and 2nd Lieut. H L Brock went out. Raiding party discovered enemy front line trench practically deserted and was subjected to very heavy fire from a support trench only 15 yards away. Raiding party found this dugout full of Germans and bombed this and the support trench. Our casualties were:
Capt H P Williams missing
Lieut. A Lloyd Jones wounded
2nd Lieut. H L Brock slightly wounded
2 men killed
5 men missing (probably killed)
24 men wounded
Three search parties succeeded in bringing in the wounded. No trace could be found of the missing.
Jun 5/6 Our patrols could discover no trace of missing in No Mans Land.
