An order came to Brigadier-General Butler to secure the line from the College to Vieux Moulin with his brigade, and to prevent any movements along the Merville—Neuf Berquin road. He accordingly went up to Battalion Headquarters, and ordered an advance at 11 A.M. At the same time he sent up two companies of the Irish Guards to advance in échelon behind the right flank, in the hope of getting in touch with the Fiftieth Division. In the 4th Battalion Captain H. Sloane-Stanley was told to push forward two platoons to seize Vierhoek, and Captain Pryce to occupy Pont Rondin with a similar force.
The following were the officers who took part in the operations from April 12 to 14:

The attack started at 11 a.m., but the Coldstream encountered such strenuous opposition that they were unable to advance more than 100 yards. Nor could No. 1 Company of the 4th Battalion Grenadiers make much headway towards Vierhoek, owing to the intense and accurate machine-gun and artillery fire, which swept the only road over the stream; and it suffered severely in its attempts to carry out the orders. Second Lieutenant Osborne, however, had managed to push on about 200 yards with his platoon when he was wounded. But No. 2 Company made a most skilful advance towards Pont Rondin, led by Captain Pryce himself.
In the houses down the road, by which the Grenadiers had to come, the Germans were posted with light machine-guns, and before any progress could be made these houses had to be cleared. Slowly and systematically, No. 2 Company worked from house to house, and silenced the machine-guns. Thirty Germans were killed in this way—Captain Pryce alone accounted for seven—and were found afterwards in the houses or near by. Two machine-guns were taken, as well as a couple of prisoners.
During the whole operation, this company was under heavy fire, not only from machine-guns but also from a battery of field-guns, which was firing with open sights from a position some 300 yards down the road. It was a remarkably fine performance, and was watched with intense interest from Battalion Headquarters, which were some 200 yards in rear of the centre of the line, in a position from which the commanding officer could see most of the trenches occupied by his battalion. Lieutenant Nash, who had brought up one platoon to support No. 2 Company, was on his way back when his hand was carried away by a shell, and the command of No. 3 Company devolved on Lieutenant M. D. Thomas.
About 3 P.M. the situation of the 4th Guards Brigade became very critical. On the right the Coldstream reported that there was no sign of the Fiftieth Division, which should have been on their right flank, and at the same time Captain Pryce sent back word that his left flank was in the air, and that Germans could be seen 1000 yards in rear of his company. He added that he was being engaged by trench mortars and field-guns, which were firing at him with open sights from the exposed flank.
Affairs on the right were improved by the arrival of a company of the Irish Guards, which, without orders, undertook a counter-attack in conjunction with a company of the Coldstream. But, having no troops to send up on the left flank, Brigadier-General Butler decided that that portion of the line must be withdrawn. Accordingly, Lieut.-Colonel Pilcher ordered Captain Pryce to fall back, but even then there was a large gap between his company and the troops on the left flank, of which the Germans took advantage. Having reached the position indicated, Captain Pryce held on to it in spite of several determined attacks by the enemy. Colonel Pilcher, accompanied by the Adjutant, Captain Gerard, visited the left of the line about 4.30 P.M. He found No. 2 Company rather scattered, as it had been compelled to form a defensive flank. Meanwhile, after an intense artillery preparation, the enemy attacked No. 1 and No. 4 Companies, and was driven back with severe losses.
All day the Battalion Headquarters were severely shelled by two German field-guns and also by trench mortars. The farm they occupied was set on fire, and both Captain M. Chapman, who had distinguished himself on many occasions as intelligence officer, and Lieutenant N. R. Abbey, who was attached to Battalion Headquarters, were killed by shells. A good many valuable men, who had served on Battalion Headquarters for a long time, were killed or wounded during the day. The farm was full of cows and horses, which had to be turned loose when the farm caught fire, and several casualties took place on this account. The Headquarters were afterwards moved to the garden of the farm. To some extent the fire was kept down by the skilful and gallant conduct of Lieutenant Lewis of the 152nd Brigade R.F.A., who exposed himself continually to get direct observation, while his guns undoubtedly inflicted heavy casualties on the advancing Germans.
