Two battalions of tanks, each of thirty-six tanks, were allotted to the Division. "B" Battalion (Lt.-Col. E. D. Bryce, D.S.O.) operated with the 16th Infantry Brigade, and "H" Battalion (Lt.-Col. Hon. C. Willoughby) with the 71st Infantry Brigade. The 18th Infantry Brigade advanced without tanks. The only points which caused anxiety, provided that the tanks functioned satisfactorily, were Couillet Wood on the right of the 16th Infantry Brigade front, in which tanks could not operate, and Ribecourt Village on the left of the 71st Infantry Brigade front. The former was successfully cleared by the Buffs, and the latter gallantly captured by the 9th Norfolk Regiment; the 11th Essex clearing and securing it for the advance of the 18th Infantry Brigade, while the 71st Infantry Brigade attacked the second objective. The 18th Infantry Brigade pushed through the 71st Infantry Brigade and secured Premy Chapel Ridge in good time, and rendered great assistance to the 51st Division on our left, who were held up at Flesquieres by guns in the valley picking off the tanks one by one as they breasted the ridge. The West Yorks and the 2nd D.L.I. each charged over the Premy Ridge spur and captured a battery at the point of the bayonet. At 3.15 p.m. the cavalry, who would have been of the greatest assistance in capturing the enemy guns holding up the 51st Division, reported that they could not advance owing to snipers in Ribecourt. The village had been in our possession since 10 a.m., and the 18th Infantry Brigade had passed through it at 11.30, and were now two miles beyond it. However, the cavalry pushed through patrols before nightfall to Nine Wood. A company of the 9th Suffolk Regiment successfully carried out its mission of advancing without artillery or tank support, and capturing the bridge at Marcoing. The Division had a most successful day, with very light casualties (about 650), capturing 28 officers and 1,227 other ranks prisoners, 23 guns, and between 40 and 50 machine-guns and many trench-mortars, and receiving the congratulations of the Corps Commander. Everything had gone like clockwork: the artillery had pushed forward to advanced positions to cover the new front before darkness came on; the machine-guns, under Major Muller, D.M.G.O., were likewise established in their new forward positions, thanks to careful arrangements and the use of pack animals; and the 11th Leicesters, under Major Radford, were repairing and clearing the roads before the third objective had been secured. The tanks, which had made surprise possible, were most gallantly handled, and all arrangements most carefully thought out by Col. A. Courage, D.S.O. The next morning the 51st Division captured Flesquieres from the north, and three companies of the 14th D.L.I., moving forward slightly in advance of them and operating with a squadron of the Queen's Bays, entered Cantaing ahead of the 51st Division, handing over subsequently to the 4th Gordons.
