Meanwhile the position on the right was full of difficulties. The 17th Battalion Royal Welsh Fusiliers had been held up, and the usual problem demanded solution: how to keep pace with the advance, and at the same time to guard the exposed flank? A platoon of No. 4 Company, under Lieutenant Oliver, at once formed a defensive flank to the right; but this was an insufficient safeguard, and as No. 2 Company continued to advance, Lieutenant Mildmay, now in command, was forced to waste half his strength in protecting the right flank. Lieutenant Jacob, who commanded No. 4 Company, sent forward one platoon to assist No. 2 in their advance, and after consultation with Captain Buchanan despatched a third platoon under Second Lieutenant Drummond to prolong the left of No. 3 Company, which was now advancing in support of No. 1. This platoon had not gone far before Lieutenant Drummond was wounded by a shell, but in spite of this, and even another wound in the neck from a bullet, he insisted on remaining with his Company until the Battalion was relieved, dealing coolly with every situation which arose. During the advance Sergeant Sharpe and two men captured a block-house 150 yards west of the railway, securing no less than twenty-one prisoners. By now the Royal Welsh Fusiliers had succeeded in demolishing the block-houses which impeded their advance, and had gained ground on the right. This enabled Lieutenant Mildmay to push on with No. 2 Company to within 80 yards of the Steenbeek, but there he was held up by machine-gun fire from Langemarck village. Any endeavour to cross the river in the circumstances would be doomed to failure, nor was there any advantage to be gained by the attempt, since the men now occupied a position with a good field of fire dominating the approaches to the river. The section of the Machine-Gun Company which followed the 2nd Battalion during this advance suffered very much from shell-fire. Lieutenant Cottle, the officer in command, was killed whilst going forward to reconnoitre, and shortly afterwards one of the guns of this section with its entire team was knocked out by a shell. The remaining guns, however, were brought up into good positions in the front line.
