On learning this, Brigadier-General Corkran decided to employ some companies from the battalions in reserve to fill up the gap, and accordingly instructed Lieut.-Colonel Maitland to send one company to support the 4th Battalion Grenadiers and another company to the Welsh Guards. No. 2 Company, under Captain Graham, was despatched to Arrow Head Copse in support of the 4th Battalion Grenadiers on the right of the Brigade, and while going on ahead to find Lieut.-Colonel Lord Henry Seymour, Lieutenant E. King was hit by a rifle bullet in the leg, and Lieutenant E. B. Shelley and Lieutenant Llewellyn were wounded shortly afterwards. Captain Vaughan, with No. 3 Company, was instructed to place himself under the orders of Lieut.-Colonel W. Murray-Threipland, while the rest of the Battalion remained a little distance behind in case of emergency. Hardly had the Welsh Guards finished their relief, when they were attacked, and had to fight hard to maintain their position. Coming on in great force as early as 3 A.M., the Germans began to press back the right of their line from the sunken road. Every available man had been hurried to the front line, where the casualties were thinning out the ranks to an alarming extent, and even the 100 Grenadiers who had been sent up as ammunition carriers had to be put in as supports. The Welsh Guards had lost a good many officers and N.C.O.’s, and matters were beginning to look serious when Captain Vaughan arrived with No. 3 Company of the 1st Battalion Grenadiers, having passed through a barrage of 5·9 shells near Trônes Wood in artillery formation. He was at once sent off by Lieut.-Colonel Murray-Threipland to take over the line on the right of the Welsh Guards and relieve the Munster Fusiliers, who had had some very heavy fighting and were much shaken. Second Lieutenant Stein went on with the leading platoon, and the relief was carried out by sections and completed by noon. It was anything but a pleasant position, as both flanks were in the air, and the Company was occupying an extended front at right angles to the trench occupied by the Welsh Guards. Captain Vaughan was told that the attack would probably come from the left, and made his dispositions accordingly. He placed two sections in shell-holes in échelon on the left, and established a double block at that end of the trench with a strong bombing section, supported by a Lewis gun; the other Lewis gun he stationed on the right flank. Second Lieutenant Sharp was in charge of the left of the Company and Second Lieutenant Stein of the right.
