Our line was also advanced north of Courcelette, while on the Fourth Army front a further portion of the enemy's fourth-system of defense northwest of Gueudecourt was carried on a front of a mile. Between these two points the enemy fell back upon his defenses running in front of Eaucourt l'Abbaye and Le Sars, and on the afternoon and evening of September 27, 1916, our troops were able to make a very considerable advance in this area without encountering serious opposition until within a few hundred yards of this line. The ground thus occupied extended to a depth of from 500 to 600 yards on a front of nearly two miles between the Bazentin-le-Petit, Lingy, Thilloy, and Albert-Bapaume roads. [Sidenote: Destremont Farm carried.] Destremont Farm, southwest of Le Sars, was carried by a single company on September 29, 1916, and on the afternoon of October 1, 1916, a successful attack was launched against Eaucourt l'Abbaye and the enemy defenses to the east and west of it, comprising a total front of about 3,000 yards. Our artillery barrage was extremely accurate, and contributed greatly to the success of the attack. Bomb fighting continued among the buildings during the next two days, but by the evening of October 3 the whole of Eaucourt l'Abbaye was in our hands. [Sidenote: Fourth Army attacks.] At the end of September, 1916, I had handed over Morval to the French, in order to facilitate their attacks on Sailly-Saillisel, and on October 7, 1916, after a postponement rendered necessary by three days' continuous rain, our allies made a considerable advance in the direction of the latter village. On the same day the Fourth Army attacked along the whole front from Les Boeufs to Destremont Farm in support of the operations of our allies. [Sidenote: Enemy's trenches east of Gueudecourt taken.] The village of Le Sars was captured, together with the quarry to the northwest, while considerable progress was made at other points along the front attacked. In particular, to the east of Gueudecourt, the enemy's trenches were carried on a breadth of some 2,000 yards, and a footing gained on the crest of the long spur which screens the defenses of Le Transloy from the southwest. Nearly 1,000 prisoners were secured by the Fourth Army in the course of these operations. With the exception of his positions in the neighborhood of Sailly-Saillisel, and his scanty foothold on the northern crest of the high ground above Thiepval, the enemy had now been driven from the whole of the ridge lying between the Tortille and the Ancre. [Sidenote: Germans make repeated counterattacks.] [Sidenote: British situation satisfactory.]
