From mid-day on the 22nd the 7th D.C.L.I. (less one company) held the south bank of the Somme Canal from the left of the Somersets at the canal junction to half a mile west of the Dury--Ollezy road. They were in touch on their left with a brigade of the 36th Division. By 11 P.M. this division had another brigade at Cugny and another at Brouchy. One company of the D.C.L.I. had been sent shortly before mid-day to fill the gap between the right of the 7th Somerset L.I. and the 14th Division. This company got into touch with the 6th Somerset L.I. (14th Division) and helped to stem the heavy attacks on Jussy before rejoining the battalion on the morning of the 23rd. “C” Company, 20th Machine Gun Battalion, was distributed so as to cover the front of the 7th Somerset L.I. and the 7th D.C.L.I., and “D” Company 11th D.L.I., under the 12th King’s, dug trenches near Dury and Tugny. The 61st T.M.B. and Brigade Headquarters were at Ollezy. The retirement on the 21st necessitated a reorganisation of the artillery covering the 36th Division. Three groups were formed. The Right Group under Lieut.-Colonel Erskine, consisting of A/91 and C/91 Batteries and the 232nd Heavy Battery, was detailed to cover the 61st Brigade. B/91 was attached to the Centre Group, under Lieut.-Colonel Potter, and D/91 to the Left Group, under Lieut.-Colonel Eley, both covering the 36th Division. On the night 21st/22nd Lieut.-Colonel Erskine established his headquarters at Ollezy, and placed his batteries west and north-west of the village to cover the crossings near St Simon. During the 22nd the 61st Brigade maintained its position along the canal. Enemy patrols crossed near Artemps in the morning and entered St Simon at 1.40 P.M., when the Somersets came under gun and trench mortar fire. During the evening the 91st Field Artillery Brigade, now reinforced by D/173 (Howitzer) Battery, was withdrawn to positions near Eaucourt, where the crossings of the canal could be as easily covered while the guns were less exposed. That night a company of the 12th King’s was driven out of Tugny, and soon afterwards, owing to the retirement of the 36th Division, the battalion, with “D” Company 11th D.L.I., fell back through the 7th D.C.L.I. to the railway, leaving one company to reinforce the D.C.L.I. at the Ollezy--Dury crossing.
