On the 15th June the Battalion returned to hold the line which it had helped to gain in April. Leaving Souastre, it marched to support at a camp near Henin-sur-Cojeul. There was practically no accommodation here and ground sheets had to be used as shelters. The following day it relieved the 10th Battalion Essex Regiment in the front line, just south of the Cojeul River Valley, opposite Cherisy. After four days in this sector it went out to Divisional reserve near Boisleux-au-Mont, where, on the 27th June, it was visited by Col. the Hon. W.L. Vane, the Honorary Colonel of the Battalion. A regular system of reliefs, which lasted for three months, now commenced. Under this system the Battalion had two periods of four days in the front line and one in support at Henin or Neuville Vitasse, followed by eight days in reserve in camp near Mercatel. The weather was good on the whole, and the trenches in excellent condition. The enemy was only moderately active and there were very few casualties. One of the Battalion areas in this sector was the bank from which the attack started on the 14th April, and whilst there a cross was erected to the memory of those who fell on that day. As a result of their long stay here, the men became very familiar with the whole area, and their experiences in the communication trenches, Foster Avenue, Shikar Lane, Kestrel Avenue, Avenue Trench and others were talked of for long after. Neither did they forget Lone Sap, from which the enemy captured two of their comrades, Cable Trench, which was raided by a party under 2nd Lieut. B.R. Leatherbarrow, Concrete Trench, the Hindenburg Line, the caves in Marliere Village, which on one occasion produced some interesting souvenirs left by the Boches, and many other localities. Apart from minor raids and counter-raids, the only outstanding incident was the double raid of the 15th September. This operation was carried out by the 9th Durham Light Infantry in the afternoon and repeated by the 8th Durham Light Infantry in the evening. The Battalion was holding the sector immediately on the right of the raiders, and its function was to draw the enemy's attention and fire by the exhibition of dummy figures and a dummy tank, which were later on view at the United Services Museum in Whitehall. 2nd Lieut. Leatherbarrow was in charge of these dummies, assisted by Sergeant P. Finn, who was awarded the Military Medal for his work. Other decorations earned during this period were Military Medals awarded to Corporal Nesbitt and Private Allison of X Company for digging out a man buried by shell fire, under very dangerous conditions.
