After three weeks out of the line the division returned to the front on 5 September north-east of Langemarck. However, having had no reinforcement, it was under strength after the Langemarck battles with an average battalion strength of only 350 rifles. Relieving the 38th (Welsh) Division, an attack on the trench line opposite Poelkapelle was scheduled for 20 September. Preceded by a "hurricane" bombardment, the 59th brigade on the left and the 60th brigade on the right attacked that morning with the left flank reaching its objective, the right flank was held up by fire from strong points and the centre (the inner flanks of both brigades) making no progress due to fire from Eagle Trench, which was later discovered to be well sited between two embankments, and had an excellent field of fire. The attack was repeated that evening, with the artillery using smoke which was only partly successful, the 11th R.B. gaining a foothold in the trench but at a cost of two thirds of its men and 11 out of 16 officers. The 60th brigade gained further ground on the right. A follow-on attack was planned for 22 September with the aid of two tanks, but these became stuck in Langemarck, and the attack was re-planned for the next day without them. A German counterattack on the 60th brigade, 35 minutes before the planned attack was beaten off, and the attack began at 07:00. With trench mortars bombarding the trench, and both brigades working their way to the centre of the trench from the ends they held using bombing parties (grenade throwers), the 12th K.R.R.C. from the south, 10th R.B. from the north and frontally from the west. A total of 158 prisoners were taken and a number of machine guns captured. The attack earned praise from the Army Commander, General Sir Hubert Gough. Until the division was relieved at the end of the month the pioneers and engineers laboured to establish and strengthen communications to the front line through Langemarck.
