The part which the 56th Division was called on to play in the offensive was that of a combined operation on a comparatively small front in conjunction with the 46th Division, which was in line opposite the northern flank of the Gommecourt Salient and adjoining the 56th. These Divisions which, with the 37th (not engaged), formed the VII Corps and were the right flank of Allenby's Third Army, were the two most northern divisions operating in the Somme offensive.
Adjoining the 56th on the right lay Hunter-Weston's VIII Corps, comprising from left to right the 31st, 4th and 29th Divisions in line, with the 48th in support. One Brigade of this last-named Division—the 143rd—was in line between the 56th and the 31st, and its sector formed a gap on which no forward move was attempted. The Gommecourt operation was therefore entirely isolated, though forming an inherent part of the one great offensive plan.
South of the VIII Corps the British battle front was taken up by the X Corps (Morland), III Corps (Pulteney), XV Corps (Horne) and XIII Corps (Congreve), these forming with the VIII, Rawlinson's Fourth Army.
The 56th Division's objectives, which will be easily followed from the map, were to capture and consolidate a line running almost due north from a strong point at the south end of Farm-Farmyard, through Fame, Felon, Fell, Fellow, and the Quadrilateral to the junction of Fillet and Indus. From this point the line was to be continued to the "little Z" (a point about 2000 yards north of the apex of the Gommecourt Salient) by the 46th Division, who were to clear Gommecourt village and park.
The 168th Brigade on the right of the Divisional sector attacked on a two-battalion front from the strong point on the right to the junction of Felon and Epte on the left. Strong points were to be consolidated on the extreme right and also at the junctions of Felon with Elbe and Epte. From this point the 169th Brigade was to continue the line to the junction of Fir and Firm and also to the point of union with the 46th Division.
The 167th Brigade was in Divisional reserve, and one battalion, the 1st Londons, was detailed to supply 600 men to dig communication trenches across No Man's Land after the attack.
The 168th Brigade group was disposed as follows:
Headquarters in Mardi Trench Assaulting Battalions— Right—London Scottish. Left—Rangers. Supporting Battalions— Right—Kensingtons, with a special task of digging a fire trench to form a defensive flank across No Man's Land from the head of Welcome Street. Left—1/4th Londons. 168th M.G. Company—In tunnelled emplacements in the WR line for overhead covering fire. 3-inch L.T.M. Battery (Stokes), (with half the 167th Brigade Battery)—In emplacements in the front line control trench.
In addition the following troops were at the disposal of the Brigadier for the operation:
