After an hour's sleep the Battalion started off again at midnight, and marched ankle-deep in mud and slush to the Headquarters of the 1st Brigade, where it received its orders for the attack in which it was to operate with the 1st Battalion Irish Guards, Royal Munster Fusiliers, and Gloucester Regiment.
The following move at 2.15 A.M., to position of readiness at S.W. corner of Polygon Wood--2nd Battalion Grenadiers, 1st Battalion Irish Guards, Royal Munster Fusiliers. Left of Grenadier Guards and right of Irish Guards at S.W. corner of Polygon Wood, both in column of route heading south. Royal Munster Fusiliers on edge of wood just in rear of centre. When ordered to move from position of readiness to attack, Grenadiers will lead in file, passing along western side of trench and shooting any enemy met with either in or out of it. Irish Guards to follow Grenadiers in same formation, Royal Munster Fusiliers to follow Irish Guards. When trench has been cleared, Battalions will occupy and hold it till further orders. Attack will be ready to start any hour after 4 A.M. All movements to be made quickly and silently. Reports to H.Q. 1st Guards Brigade. Captain Fortune, Black Watch, will act as guide to Grenadiers. Battalions in rear will keep touch with Battalions in front of them. Gloucesters will fill gap as at present.
At 3 A.M. these battalions started. It had been arranged that the Irish Guards should lead as far as Polygon Wood, and General FitzClarence and his Staff walked at their head. In spite of the darkness the battalions kept well together. They were marching down a muddy lane when suddenly some shots were heard in front, and General FitzClarence halted his force and went to see what was going on. The advance began again slowly, they reached the west edge of the wood, and the Grenadiers got into the ditch at the edge. Then came the news that General FitzClarence had been mortally wounded. Colonel Davies arrived next with the Oxfordshire Light Infantry, having reconnoitred the positions; he had found that the Germans were in great strength, with wire entanglements in front and several machine-guns.
The question now arose: What should be done? Was it wise to carry on the attack with no General in command? Eventually the matter was referred to Brigadier-General Westmacott, commanding the 5th Brigade. He decided that it would be best to abandon the attack, as after this delay there would not be enough time for it to develop before daybreak. He therefore ordered the battalions back behind the wood, west of Nonne-Bosschen Wood, and determined to hold a new line. Colonel M'Ewen of the Camerons was sent for, to take command of the Brigade.
