The 7th Argyll and Sutherland Highlanders had moved off at 11.40 A.M. on the 9th, and after various vicissitudes and alterations of plans, due to rapidly changing circumstances, were finally disposed with the 7th Argyll and Sutherland Highlanders along the west bank of the Lawe from Pont Tournant inclusive to Boundary Bridge. The 4th Gordon Highlanders remained in reserve about Les Caudrons. At 7 P.M. the Divisional artillery came into action between the villages of Paradis and La Croix Marmuse. Thus at nightfall the Division was in position in the same order of battle as in the operations about Bapaume: 154th Brigade on the right, 152nd Brigade in the centre, and 153rd Brigade on the left. On the flanks touch was maintained on the right with the 55th Division, who were still in their original front line, but had been compelled to form a defensive flank to connect up with the river Lawe; on the left with the 50th Division, who were being heavily engaged about Estaires. The 51st Division was entirely west of the Lawe, except for the 6th Gordon Highlanders at Vieille Chapelle, the 5th Seaforth Highlanders at Fosse, and the one platoon of the 7th Gordon Highlanders south of the Lestrem Loop. By dawn on 10th April the whole Division, less the 4th Seaforth Highlanders, had reverted to the command of General Carter-Campbell. No changes had been made in dispositions during the night except that half the reserve company of the Divisional machine-gun battalion had been sent forward to reinforce the 153rd Brigade front, while two companies of the 39th Machine Gun Battalion, due to arrive at Calonne during the day, were placed at the disposal of the Division. Throughout the day the 152nd Brigade experienced the most sanguinary fighting. The enemy during the night had, in a brilliant enterprise, managed to dribble across Boundary Bridge and push machine-guns and riflemen into the farms just west of it. These he covered by other machine-guns on the eastern bank of the Lawe. From the farms and out-buildings he inflicted numerous casualties to the 6th Seaforth Highlanders by close-range machine-gun fire. When daylight came, he attempted to reinforce them by pushing parties across the bridge, over which only one man could advance at a time. The Seaforths put a stop to this manœuvre by rifle and Lewis-gun fire, and many Germans shot on the bridge were drowned in the river. A counter-attack was launched against the farms by two platoons of the 6th Seaforth Highlanders, supported by covering fire from the 8th Argyll and Sutherland Highlanders, but it broke down under the intense volume of machine-gun fire directed against it.
