The four tanks detailed to attack the Quadrilateral again had bad luck, one being turned absolutely turtle by a mine field.

The three battalions of the 18th Infantry Brigade met at first with little success, the 11th Essex on the left establishing a rather precarious footing in one face of the Quadrilateral, and the 1st West Yorkshire Regiment getting in at one point in Douai Trench, running south from the Strong Point.

The D.L.I., attacking south of them through Holnon Village, could make no headway.

The French had during the morning captured Round Hill and part of Manchester Hill, and came up in line with us.
The 16th Infantry Brigade fared much better, and working down from the north was able in the course of the day to secure the northern face of the Quadrilateral.

Their four tanks were of great assistance to them this day.
