The attack on the 25th, with the subsequent capture of Lesboeufs, formed one of the most successful operations in which the Guards Division was engaged in the war. The preparation seems to have been complete, and every possible contingency foreseen. In the first attack on the 15th the 4th Grenadiers had been in reserve, and so had not seen so much of the fighting as the Chapter other battahons in the Division, but it was now to take a leading part, and to go through some of 4^th Batt. the toughest fighting of the whole battle of the Somme. Orders were given for the attack to be carried out by Pereira's Brigade on the right and Corkran's on the left, while Ponsonby's Brigade remained in reserve. In Corkran's Brigade, the 2nd Battalion Scots Guards were to take the right and the 4th Battalion Grenadiers the left.

When the 4th Grenadiers moved up on the night of the 24th, No. 4 Company under Second Lieutenant Constable on the right and No. 2 Company under Captain Britten were sent to the support trenches in front of Ginchy, while No. 1 Company under Captain Goschen and No. 3 under Captain Stewart remained in Trones Wood. On the left of the Grenadiers was a battalion of the King's Own Yorkshire Light Infantry, but it was to start from a line quite 100 yards in front of the assembly trench occupied by No. 2 Company, which made communication difficult. Captain Britten, realising that it was essential to keep touch with the battalion on the left, made his men deepen a shallow communication trench which ran in that direction.

For the last five nights the 4th Grenadiers had been constantly employed in digging and had been obliged to get what sleep they could during the day — not at all the same thing as a good night's rest.

From 10 to 12 noon the artillery bombardment continued and was supplemented by the Stokes mortars in the support trenches. During these preliminaries Second Lieutenant Maine was wounded in the foot, and sent down to the dressing station.  As zero time approached the men fixed bayonets

4th Batt. and remained motionless, waiting for the whistle which was to be the signal to advance. The officers in each company had carefully explained to the platoon and section commanders exactly what was expected of them, and each non-commissioned officer therefore knew as much as the captain.

At 12.35 P.M. the line advanced, preceded by a creeping barrage, which moved 150 yards ahead at the rate of 50 yards per minute. In perfect order, with not a man out of his place, the line swept on until it came to the two intermediate lines, which the officers had been warned to expect somewhere in front of the first objective. These had only recently been discovered, and no one quite knew how strongly they were held. Although the leading companies closed up as near as they could to the creeping barrage, they were met by a terrific machine-gun and rifle fire from the intermediate lines, and terrible gaps were made in the ranks. But the companies pressed on and made short work of the Germans in these lines. Over 150 were killed there with the bayonet. Re-forming again, the Grenadiers rushed the first objective, which, to their surprise, offered comparatively little resistance. Our guns, however, had dealt effectively with the first objective, and forced the occupants into dug-outs, whereas the intermediate lines had only been passed over by the creeping barrage. On the right the Scots Guards met with little opposition and easily secured their first objective with no serious loss.

An hour later, at 1.35 p.m., the attack on the Chapter second objective started, and the 4th Battalion Grenadiers moved forward, preceded as before 4thBatt. by a creeping barrage. Although there was some stiff fighting at the end, the second objective was secured up to time. The brigade on the left had been held up, and the usual difficulty arose of one brigade pressing on while another was kept back. The right of the 4th Battalion under Sergeant Pitt had managed without difficulty to keep touch with the Scots Guards and had reached the second objective, but on the left, which was in the air. Second Lieutenant Keith was unable to advance while he had the Germans on the left in the same trench as his Company. In fact, the situation on the left had resolved itself into a bombing fight, and while the right got forward the left had always to form a defensive flank.

At 2.35 P.M. the 1st Battalion Grenadiers passed through the leading battalions and attacked the third objective ; but, as the left flank was still exposed, the result was the same — the right got well forward while the left echeloned back and dug in. To fill the gaps the Welsh Guards were sent up, and thus a continuous line, nearly 1400 yards long, was made, protecting the left flank of the Division.

That night the position was as follows: the 1st Grenadiers on the right in the third objective, facing east; the 2nd Battalion Scots Guards in the centre, facing east and north-east; the 1st Battalion Welsh Guards and 4th Battalion Grenadiers on the left, facing north. The 1st Battalion Grenadiers were in touch with the 1st Guards Brigade on the northern outskirts of Lesboeufs, and although the enemy made counter-attacks in several places, the situation remained unchanged during the night.

In spite of their heavy fighting, the men were in very good spirits and made a hearty meal off the German rations which they found, ending up with German cigars. Water was the difficulty at first,. but parties soon came up with this, as well as food and ammunition. The only company officers now left with the Battalion were Lieutenant Farquhar, Second Lieutenant Keith, and Second Lieutenant J. W. F. Selby-Lowndes, and the untiring energy they displayed elicited the highest praise from the Commanding Officer.

A tank made its appearance at 6am and slowly crawled along on the left of the Division towards the Gird trench, where the brigade on the left had been checked. This trench was very strongly held by the enemy, but when the tank arrived and fired into it 300 Germans surrendered, and the Durham Light Infantry moved up and took possession of it. The Leicester Regiment continued the line to the left towards Gueudecourt. At noon a large number of Germans were seen to leave their trenches between Gueudecourt and Le Transloy and retire across the open in great disorder, dropping their rifles and equipment as they went. Frantic messages were sent back by telephone to our artillery, which opened fire on them and inflicted heavy losses.

A squadron of our cavalry rode up towards Gueudecourt, and a cavalry patrol from the 5th Lancers went towards Lesboeufs, but Lord Chapter Cavan decided that the situation did not permit of cavalry going through, and they retired. Between 8 a.m. and noon the enemy ceased shelling, but between 12 noon and 2 p.m. a barrage was sent over by the enemy's artillery on our two front support lines. Subsequently this died down, and the evening was comparatively quiet. Throughout the day the companies in the front line suffered a good deal from small parties of snipers concealed in shell-holes, but the patrols eventually cleared the ground. At 10 p.m. the 4th Battalion was relieved by the 2nd Guards Brigade and went into bivouacs at Carnoy.

From the 18th to the 26th the casualties in the 4th Battalion were 445, exclusive of officers. Among the officers Captain C. G. Goschen, Captain W. A. L. Stewart, Lieutenant the Hon. E. W. Tennant, Lieutenant J. F. J. Joicej^-Cecil, Second Lieutenant D. O. Constable, Second Lieutenant M. H. F. Payne-Gallwey, and Second Lieutenant A. C. Flower were killed, and Captain E. G. Spencer-Churchill, Captain C. R. Britten, Second Lieutenant A. R. Ellice, and Lieutenant H. C. S. Maine were wounded. Second Lieutenant A. R. Ellice died of wounds three days later.
