Upon October 16th and 17th the division had advanced from Ypres and occupied the line already mentioned, the right centre of which rested about the ninth kilometre on the Ypres-Menin road, the order of the brigades from the north being 22nd, 21st, and 20th. On October 18 the division wheeled its left forward. As the infantry advanced, the covering cavalry soon became aware of grave menace from Roulers and Courtrai in the north. A large German force was evidently striking down on to the left flank of the advance. The division was engaged all along the line, for the 20th Brigade upon the right had a brisk skirmish, while the 21st Brigade in the centre was also under fire, which came especially heavily upon the 2nd Bedfords, who had numerous casualties. About ten o'clock on the morning of the 19th the pressure from the north increased, and the 7th Cavalry Brigade was driven in, though it held its own with great resolution for some time, helped by the fine work of K Battery, R.H.A. The 6th Cavalry Brigade was held up in front, while the danger on the {237} flank grew more apparent as the hours passed. In these circumstances General Rawlinson, fortified in his opinion by the precise reports of his airmen as to the strength of the enemy upon his left, came to the conclusion that a further advance would place him in a difficult position. He therefore dropped back to his original line. There can be little doubt that, if he had persevered in the original plan, his force would have been in extreme danger. As it was, before he could get it back the 1st Welsh Fusiliers were hard hit, this famous regiment losing a major, 5 captains, 3 lieutenants, and about 200 men. The order to retire had failed to reach it, and but for the able handling of Colonel Cadogan it might well have been destroyed. On October 20, the situation being still obscure, the 20th Brigade carried out a reconnaissance towards Menin. The 2nd Wilts and 2nd Scots Fusiliers, of the 21st Brigade, covered their left flank. The enemy, however, made a vigorous attack upon the 22nd Brigade to the north, especially upon the Welsh Fusiliers, so the reconnaissance had to fall back again, the 1st Grenadier Guards sustaining some losses. The two covering regiments were also hard pressed, especially the Wiltshires, who were again attacked during the night, but repulsed their assailants. [Sidenote: A deadly ordeal.]
