About 200 prisoners were captured on May 16. Fighting was resumed at daybreak; and by eleven o'clock the 7th Division had made a considerable advance, capturing several more of the enemy's trenches. The task allotted to this Division was to push on in the direction of Rue D'Ouvert, Chateau St. Roch and Canteleux. The 2d Division was directed to push on when the situation permitted toward the Rue de Marais and Violaines. The Indian Division was ordered to extend its front far enough to enable it to keep touch with the left of the 2d Division when they advanced. On this day I gave orders for the 51st (Highland) Division to move into the neighborhood of Estaires to be ready to support the operations of the First Army. At about noon the enemy was driven out of the trenches and posts which he occupied between the two Divisions, the inner flanks of which were thus enabled to join hands. By nightfall the 2d and 7th Divisions had made good progress, the area of captured ground being considerably extended to the right by the successful operations of the latter. The state of the weather on the morning of May 18 much hindered an effective artillery bombardment, and further attacks had, consequently, to be postponed. Infantry attacks were made throughout the line in the course of the afternoon and evening, but, although not very much progress was made, the line was advanced to the La Quinque Rue-Bethune Road before nightfall. On May 19 the 7th and 2d Divisions were drawn out of the line to rest. The 7th Division was relieved by the Canadian Division and the 2d Division by the 51st (Highland) Division. Sir Douglas Haig placed the Canadian and 51st Divisions, together with the artillery of the 2d and 7th Divisions, under the command of Lieutenant-General Alderson, whom he directed to conduct the operations which had hitherto been carried on by the General Officer Commanding First Corps; and he directed the 7th Division to remain in Army Reserve. During the night of May 19-20 a small post of the enemy in front of La Quinque Rue was captured. During the night of May 20-21 the Canadian Division brilliantly carried on the excellent progress made by the 7th Division by seizing several of the enemy's trenches and pushing forward their whole line several hundred yards. A number of prisoners and some machine guns were captured. On May 22 the 51st (Highland) Division was attached to the Indian Corps, and the General Officer Commanding the Indian Corps took charge of the operations at La Quinque Rue, Lieutenant-General Alderson with the Canadians conducting the operations to the north of that place. On this day the Canadian Division extended their line slightly to the right and repulsed three very severe hostile counter-attacks. On May 24 and 25 the 47th Division (2d London Territorial) succeeded in taking some more of the enemy's trenches and making good the ground gained to the east and north.
