On September 18 the Fifth Corps attacked once more in conjunction with Rawlinson's Army on its right, the final objective being the trench lines south of Villers-Guislain-Gauche Wood. The advance was made by the Welsh Division opposite to Gouzeaucourt, the Seventeenth in front of Gauche Wood, and the Twenty-first to the immediate south. It was preceded by field barrage, heavy barrage, machine barrage, trench mortar bombardment, and every refinement of artillery practice as elaborated in this long war. The results of a hard day's fighting were rather mixed. The Welsh Division was held near Gouzeaucourt and finished up in its own original line, leaving the left flank of the 52nd Brigade exposed. The two other divisions were able, after hard fighting, to reach their objectives, including Gauche Wood. {97} The Twenty-first Division had a particularly trying and yet successful day, all three brigades being heavily engaged and enduring considerable losses in capturing the very ground which they had held on March 21. Their advance was complicated by a mine-field, laid down by themselves and so well laid that it was still in a very sensitive condition, while the dug-outs had been so undisturbed that the 1st Lincolns actually found their own orderly papers upon the table. In the fighting the 62nd Brigade led the way with complete success, and it was not until the 64th and the 110th Brigades passed through it and began to debouch over the old No Man's Land that the losses became serious, Epéhy and Peizières being thorns in their flesh. Colonel Holroyd Smith of the 15th Durhams was killed, but the 64th Brigade made good its full objective, the 1st East Yorks capturing a German howitzer battery, together with the horses which had just been hooked in. At one time the Germans got round the left flank of the Division and the situation was awkward, but Colonel Walsh of the 9th Yorks Light Infantry, with his H.Q. Staff, made a dashing little attack on his own, and drove the enemy back, receiving a wound in the exploit. The Twenty-first Division, save on the right, had all its objectives. The left of the Third Corps had not prospered equally well, so that a defensive line had to be built up by Campbell in the south, while Robertson did the same in the north, the whole new position forming a marked salient. Two efforts of the enemy to regain the ground were beaten back. The southern divisions had been much troubled by flanking fire from Gouzeaucourt, so an effort was made that night to get possession of this place, the {98} 6th Dorsets and 10th West Yorkshires of the 50th Brigade suffering in the attempt. This attack was led by General Sanders, who had succeeded Gwyn, Thomas as Brigadier of the 50th, but he was himself killed by a shell on September 20. Some 2000 prisoners and 15 field-guns were the trophies taken in this operation by the Fifth Corps. Gouzeaucourt was shortly afterwards evacuated, but there was
