Having received orders the night before to be ready at a moment's notice, the Battalion was under arms soon after dawn next day. But it was not until much later that it got instructions to move to the other side of the Racecourse Wood, and entrench a position almost at right angles to the line of trenches in front. It turned out that the Seventh Division on the right had been driven back, and though most of the ground had been regained there was still a risk of the Germans pushing through. Meanwhile, Captain Ridley was ordered to take No. 4 Company, and support the Cameron Highlanders near the Château. He sent up two platoons into the trenches on their right, and kept the rest in support. They came in for a good deal of shell-fire, but were not seriously attacked. [Sidenote: Oct. 30.] Except for No. 4 Company the Battalion was in Corps Reserve next day with the Irish Guards, while the 2nd and 3rd Battalions Coldstream were in the trenches. But about 3 P.M. the Brigadier, Lord Cavan, got news that there had been a serious break in the line about two miles to the right, _i.e._ the south, and was instructed to send up the battalions, which he had in reserve, to report to General Bulfin, commanding the 2nd Brigade. Lord Cavan went himself to see General Bulfin at his Headquarters, and was directed to despatch these battalions southwards to protect the right flank of the 2nd Brigade. Accordingly the 2nd Battalion Grenadiers, Irish Guards, and Oxfordshire Light Infantry marched off from Polygon Wood towards Klein Zillebeke, and Captain Ridley was ordered to withdraw No. 4 Company and join the remainder of the Battalion as it moved off. The orders given to Lieut.-Colonel Smith were to reinforce the cavalry, which was holding a line very lightly north of the Château de Hollebeke. By dusk these battalions were astride of the Klein Zillebeke--Zandvoorde road, the Grenadiers on the right and the Irish Guards on the left, with their left thrown forward a little, to keep touch with the right of the 2nd Brigade. Lord Cavan went on ahead with his Staff, to see that the whole line was made continuous. On going forward to inspect the position which the cavalry was holding, Lieut.-Colonel Smith found that it was on a forward slope, which seemed to him untenable, and he thought this a good opportunity for making a fresh disposition. So he arranged with the cavalry that it should continue to hold its line, while the Battalion dug in, in its rear. A new line, which consisted as usual of a series of deep narrow holes with no parapet, was accordingly made, with the right on the railway, and the left on the Klein Zillebeke road.
