Farther still to the north, the Sixth Division had moved towards the Dynamite Magazine and Nash Alley, but here also the attack was held by the defence. On the whole, in spite of the prisoners and in spite of Guémappe and {71} Gavrelle, it was doubtful if the gains made up for the losses upon the day's balance. [Sidenote: April 24] A second day of hard fighting was destined to follow that of April 23, though the advance began later in the day. In the area of the Seventh Corps some advance was made in the centre and two field-guns were captured. The Sixth Corps also went forward again. The front attacked was strong, the fire heavy, and the attacking troops had again and again been through the furnace, which had only tempered their courage, but had woefully consumed their numbers. The Fifteenth Division in the south got forward some distance and dug themselves in on the new line. The Twenty-ninth also made some gains, but were unable to retain them, and fell back upon their old line. In the movement some of the parties to flank and rear were overwhelmed, and 250 men, including 3 officers, were taken. In the north, the Seventeenth Division held its old line, and did not join in the advance. After nightfall the Twelfth Division came into line again, relieving the weary Twenty-ninth. Farther north the Seventeenth Corps and the First Army were driving back counter-attacks. The next day (April 25) saw the long struggle still renewed. In the early morning the 50th and 52nd Brigades of the Seventeenth Division went forward and made some progress, as did the indomitable Fifteenth Division in the south. It was clear, however, that the forces available for attack were not strong enough to attain any considerable result in this portion of the line. The Fifteenth, however, were not to be denied, and with extraordinary tenacity they made a sudden night attack upon April 26, and {72} for a time got possession of a strong German post, called Cavalry Farm, which barred the way. The [Sidenote: April 27] enemy counter-attacked in the early morning of April 27 and re-occupied the Farm, but the Scotsmen held firmly to the trenches immediately south of it. At this date the Seventeenth drew out of the line and the Third came in again in the centre of the Corps front, while the Twelfth moved to the left. They were just in time to meet a strong German night attack upon April 27, which broke before the rifle and machine-gun fire of the infantry at the point of contact between the two divisions. The German losses were heavy, and they left a few prisoners behind them. [Sidenote: April 28]
