The battalion after being held in support all day on Saturday 25th Sept 1915 advanced at 5pm from amma front trench at point L in line of half companies with the 10th A & S Hlrs [Argyle & Sutherland Highlanders] immediately to our front. We advanced until arriving at Foss trench about 6pm which we occupied.
At 7pm two companies were forward to support the 11th and 12th Royal Scots in Pekin Trench on their left. Between 9 and 10 German bombers forced us to withdraw from Pekin Trench to Fosse Trench. Shortly afterwards the battalion withdrew from this trench and 3 companies returned to our old support line the remaining company taking up position in Hohenzollern Redoubt.
Early on the morning of the 26th the Middlesex relieved this company who rejoined the remainder of the Battalion. The battalion then reformed in the Quarry and remained there until the afternoon of the 26th when two coys were sent forward to Hohenzollern and at 5.30pm the remaining 2 Coys and machine gunners were also sent to Hohenzollern where the Battalion took up position and held until midnight when it was ordered forward to Fosse Trench reaching this position about 7.30am [27th] with the A & S Hlrs on our left but no touch could be obtained with our own troops on the right.
We remained in these trenches until the afternoon of the 27th inst.
