The 139th Infantry Brigade of the 46th Division remained in position at Sequehart, together with two companies Life Guards Machine-gun Battalion, to secure the right flank against counter-attack.

The machine-gun nests on the Sequehart-Mericourt road enfiladed the start line of the 6th Division, and the G.O.C., 139th Infantry Brigade (Brig-Gen.

J.
Harington), was asked to capture these just before the general attack.
The 46th Divisional Pioneer Battalion (1/1st Monmouthshire Regiment) undertook this task, and twice attacked the position but without success, in spite of the greatest gallantry.

The Commanding Officer (Col.

Jenkins) and his Adjutant were both unfortunately killed.
