On the evening of the 8th the Brigade moved forward to take up its prearranged position of assembly in support to the Jullundur Brigade.

The position taken up by the 1/4th Londons and the 9th Bhopals was in shallow assembly trenches in the orchards about the junction of Sign Post Lane with Rue Tilleloy. These trenches were hastily dug and very shallow, without either traverses or any sort of shelter; and it was therefore fortunate that the weather was unusually warm and fine for the time of year. The Connaughts and the 57th Rifles occupied the old British front line (as it had been before the battle of Neuve Chapelle) astride Sign Post Lane.

During the whole of the 9th, 10th and 11th May the 1/4th London remained in these trenches under continual heavy shell fire: though owing to the lack of success with which the main operation had met it was not called upon to advance.

On the evening of the 11th it was withdrawn with the rest of the Brigade to billets at Riez Bailleul. On return to billets great discomfort was caused to all ranks by the discovery that the billet in which the packs had been deposited during the three days spent in trenches had been burnt to the ground, involving the total destruction of its contents together with a mail from home. The following day the Indian Corps Commander (Sir James Willcocks) visited the Battalion and expressed his deep appreciation of its conduct at Ypres.

The 12th May dawned dull and misty and artillery observation was exceedingly difficult; and for this and other causes the renewal of the attack was again postponed until the 15th. The Meerut Division was again responsible for the Indian Corps attack. The Lahore Division adopted a role similar to that which it had played on the 9th, and the Ferozepore Brigade moved forward once more on the evening of the 15th May to its former assembly positions about Sign Post Lane.

In order to endeavour to secure the surprise effect which had been lacking on the 9th it was decided this time to deliver the attack at night, and after a preliminary bombardment the assaulting columns dashed forward at 11.30 p.m. on the 15th. On the right of the attack in the region of Festubert and La Quinque Rue considerable success was achieved by the 7th Division, and some advance was also made by the 2nd Division which was operating on the immediate right of the Indians.

The Meerut Division, however, was again faced with a hail of lead from the enemy lines under which it was impossible to live, and though the troops did all that men could do, by 4 a.m. on the 16th, after two gallant efforts, the attempts of the Indians to advance were definitely checked and the remains of the assaulting columns were once more back in their original trenches.

From this date onwards operations were confined to the southern area in the neighbourhood of Festubert, and though the battle continued to rage until the 25th May, the Indian Corps was no longer concerned in it beyond the preparations necessary to enable it to conform to the advance on its right flank.

During the early part of the month the 1/4th Londons received further officer reinforcements as follows:
