The chief obstacle to a further advance was an enemy strong point called the Crescent. Accordingly a party was organised to attack it, consisting of two bombing squads, one each from the 6th and 8th Battalions under 2nd Lieut. J.F.G. Aubin, now Brigade Bombing Officer. Leaving by way of Crescent Alley at 6 p.m., they met with considerable shell fire and were disorganised. Re-forming, however, they went out again with the same result. The shelling proved to be the preliminary to an attack on the 150th Brigade, which was beaten off, Y Company being used to assist their neighbours with Lewis guns. The following day (18th) was misty, and it was thought that the Germans were evacuating Starfish trench. An attack was therefore ordered to occupy it. This attack was made by the 6th Battalion on the left and the 9th on the right, each providing 100 men. 2nd Lieut. W. Little, with 50 men of W Company, composed the Battalion's front line, and 2nd Lieut. W.F. Charlton, with 50 of Z Company, the supporting line. A few men of other Companies were also mixed with these two lines. Shortly after starting they came under heavy machine-gun fire and had a number of casualties, including 2nd Lieut. Charlton, who was killed. Some of the party returned to their line during the day and others at night. All who had been near the enemy trench reported it to be strongly held. During the morning Y Company were sent up to relieve W, X and Z Companies in the front line. Owing to the trenches being very muddy after rain, and at all places very shallow, this was a difficult operation. To add to the difficulty the 8th Battalion began to arrive to relieve the Battalion before the Company relief was complete. However, they at last got out and moved back to 6th Avenue East and the intermediate line, where two days were spent in cleaning up. Here Lieut. Ebsworth rejoined as Adjutant, and the officers and men who had been left at the transport lines also came up. On the 20th September, the Battalion moved further back to shelter in Mametz Wood, where a draft of 50 men from the 2/6th Battalion, Essex Regiment, joined. After four days' rest it again went forward to the intermediate line. The same day Major Wilkinson, of the 149th Machine Gun Company, joined as second in command. The following night the whole Battalion turned out to dig a jumping-off trench. Lieut.-Col. Jeffreys took them as far as the Battalion Headquarters of the 5th Durham Light Infantry from where Lieut. Ebsworth and a guide led them to the position. The guide lost his way, and after wandering about nearly all night, the Battalion returned without doing any work.
