On the 22nd orders were issued for a farther advance the next day. Brigadier-General Sergison-Brooke, in command of the 2nd Guards Brigade, was instructed to advance. On his left the Third and Fifty-sixth Divisions would operate, and on his right the Second Division would capture Gomiecourt. The enemy was to be pressed continuously in order to conform to the attack by British and French troops elsewhere. On the 23rd the enemy shelled Boiry with gas and high-explosive shells, but did not offer any serious resistance. Sergison-Brooke's 2nd Guards Brigade met with little opposition, and gained all their objectives along Hamelincourt Trench, capturing Hamel Mound. Orders were then sent to Brigadier-General Sergison-Brooke to advance on the line Judas Farm--St. Leger Mill, while Brigadier-General Follett was told to move up the 3rd Guards Brigade, and be prepared to relieve the 2nd Guards Brigade in the evening. Meanwhile the Second Division had captured Ervillers. The great feature of the day's fighting was the advance of the 1st Battalion Grenadier Guards, which had been placed at the disposal of General Sergison-Brooke. After a long approach march, this Battalion, advancing with both flanks exposed, passed through Sergison-Brooke's Brigade, and seized the key-position south-west of St. Leger. The capture of this position enabled the divisions on both flanks to advance the following day with little loss. [Sidenote: Aug. 23.] That night when the 3rd Guards Brigade relieved the 2nd, the Guards Division had reached the line running through Mory Switch as far as Judas Trench, thence to Judas Farm, and on to Boyelles Reserve, where it was in touch with the Fifty-sixth Division. The next morning--the 24th--the 3rd Guards Brigade continued the pursuit of the Germans, and was ordered to advance on St. Leger, which was not to be entered by the battalions engaged in the attack, as the battalion in reserve would be responsible for the "mopping up" of the town. This advance was successfully accomplished, but after St. Leger had been secured, it was found impossible to make any further progress until Mory Copse was cleared. The Second Division was accordingly ordered to take and hold Mory Copse, while the 3rd Guards Brigade was to push forward at once, and conform to the general advance. As soon as Mory and Mory Copse had been secured, the Second Division advanced on Behagnies and Sapignies. [Sidenote: Aug. 25.]
