1. The 101st Infantry Brigade was holding a line south of the Bac St. Maur-Armentiéres Railway, with the 16th Battalion Royal Scots on the right and the 11th Battalion Suffolk Regt. on the left. This line the enemy had penetrated near the Rue Delpierre, between the two battalions. 2. The Battalion was ordered to send up two companies to close this gap in the line, and to place its remaining companies in positions north of the railway, in support of the Royal Scots and Suffolks respectively. Company commanders were immediately summoned and the situation was explained to them. C Company, with D Company in support, was ordered to move up by the Rue Delpierre and close the gap. B Company, with A Company in support, was to assemble near the Rue du Moulin and advance to the assistance of the Royal Scots. About 10-0 a.m. all companies moved off and Battalion H.Q. went forward to Wigan Post, some 500 yards north of the river. Enemy shells were already bursting around, and several direct hits were made on the road. The numbers of wounded who were streaming back showed only too clearly how severe the fighting was. Yet, quietly and in perfect order, the companies marched down to the River Lys by platoons. The main bridge was destroyed, but B Company, which was leading, succeeded in crossing by a wooden bridge near by, though this was also badly broken and only possible for men in single file. All the other companies crossed by a wooden bridge near the church. From this time, except A and B Companies which were in close touch throughout the day, companies were separated and their doings must be told individually.
