On the morning of the battle the general disposition of the Fifth Corps had been that the Seventeenth Division (Robertson) was in the line on the left, the Sixty-third Naval Division (Lawrie) in the centre, and the Forty-seventh Division (Gorringe) on the right, being the southern unit of the Third Army, in close liaison with the Ninth Division, the northern unit of the Fifth Army. Two divisions were in close reserve, the Second (Pereira) on the right, and the Nineteenth (Jeffreys) on the left.

Fourth and Fifth Corps. March 21.

The Forty-seventh Division was in a particularly important position, since it was the flank unit and the liaison between the two armies depended upon it. It had only come into line the day before the battle, taking the place of the Second Division, which was now in immediate support. On March 21 the 140th Brigade covered the right of the divisional front, and the 141st the left, the sector being that of La Vacquerie. In view of the menacing attitude of the enemy both the 142nd Brigade and the 4th Welsh Fusiliers Pioneer Battalion were brought nearer to the front line. So heavy was the gas bombardment in the morning that the front battalion of the 140th Brigade, the 17th London, had to evacuate some advanced trenches and to wear their gas masks for hours on end. The front line trenches were blown to fragments, and so also were many of their garrison. The following infantry advance, however, though vigorously conducted, had no great weight, and seems to have been the work of two battalions carrying out a subsidiary attack. By a counter-attack of the 19th London they were driven out once more.

Whilst this partial attack had been made upon the Forty-seventh Division, similar assaults had been made upon the Sixty-third in the centre, and upon the Seventeenth in the northern sector of the Fifth Corps. None of them made more than petty gains, but in each case the bombardment was formidable, chiefly with trench-mortar bombs and with gas. In the case of the Forty-seventh Division there was a considerable interval between the front brigades, because a number both of the 18th and 17th London had been absolutely destroyed, together with their trench. There were several other partial attacks during the day, but the pressure was never extreme, and the withdrawal to Highland Ridge after dusk was carried out on account of the general tactical position. All wounded men were carried back, and no booty left to the enemy.

Meanwhile the left flank of the Fifth Corps had been covered by the 58th Brigade of the Nineteenth Division, the 9th Welsh Fusiliers being heavily engaged. During March 22, Havrincourt, Herrmies, and the Beaumetz-Hermies line were held by the Seventeenth, Nineteenth, and Fifty-first divisions against repeated German attacks, and in the evening the Nineteenth was in touch with the Forty-first on its left and with the Second on its right.

Fourth and Fifth Corps. March 22.

On this night of March 22 the principal change was this movement backwards of the whole Fifth Corps. The retirement of the Fifth Corps continued during the day of March 23, and was caused by the necessity of conforming with the Seventh Corps to the south of it which, after valiant exertions, soon to be described, had lost Nurlu, so placing the enemy upon the right rear of the divisions in the north. Fins had also been taken in the same neighbourhood, The Fifth Corps was now heavily pressed in its retreat, all five divisions enduring considerable losses and having the menace of the enemy constantly upon their right flank. At noon the general line was east of Equancourt, and this line was held for a time, but the enemy was still thundering on in the north, his fresh divisions rolling in like waves from some inexhaustible sea. At 1.30 they were pushing their attack most desperately upon the weary fringes of riflemen and groups of tired machine-gunners, who formed the front of the Forty-first Division between Beugny and Lebucquière. In all, this division, with the Nineteenth and Fifty-first upon their right, sustained five strong attacks in the afternoon of this day, most of them from Vaulx-Vraumont. Eventually Lebucquière was taken, the enemy breaking their way at this point through the line of the exhausted Fifty-first Division, who had fought with splendid resolution. This German success placed the Nineteenth Division south of Beaumetz and at Beugny in a very serious position, as the enemy infantry got behind the 9th Welsh Fusiliers and 6th Wiltshires, who were only saved from total destruction by the staunch support of the 9th Welsh at Beugny, who held on desperately until the remains of the 58th Brigade could get back to them. These remains when the three battalions were reunited were only a few hundred men. The case of the 57th Brigade, which was fighting a hard rearguard action all afternoon, was little better, and both the 8th Gloucesters and 10th Worcesters were almost overwhelmed by the swarms of Germans who poured up against their front and flank. A splendid stand was made by this brigade north-east of Velu, in which the men of Gloucester especially distinguished themselves, Captain Jones of A Company receiving the V.C. for his heroic resistance. Colonel Hoath of the 10th Warwicks conducted this arduous retreat, and his own battalion shares in the honours of a fight which was tragic in its losses, but essential for its effect upon the fortunes of the army. Captain Gribble of this battalion also received the V.C., his D Company falling to the last man after the best traditions of the British army. The 5th Brigade of the Second Division, upon the right of the Nineteenth Division, shared in the honours of this desperate business, the 2nd Oxford and Bucks being very heavily engaged. After the prolonged action the final line of the Nineteenth Division ran west of Bertincourt, the movement of retreat being to the south-west. So confused had been the fighting of the last two days that the Nineteenth Division which had been on the right of the Fifty-first was now upon their left. Still keeping a closely-knit line and their faces to the foe, the Third Army stretched that night from Sailly in the south to the west of Henin and Monchy. The Fourth Corps, which had been so badly mauled, was strengthened that evening by the inclusion of the Forty-second Division. The towers of Bapaume in the rear showed how far across the ravaged and reconquered land the British line had retreated.

The pressure here described had been upon the left of the Fifth Corps, but the situation upon its right flank had also been very awkward. The terrific weight thrown upon the Ninth Division had, as will be described, driven them farther westward than their left-hand companions of the Forty-seventh Division. The result was a most dangerous gap which exposed the whole rear of the Third Army. The 99th Brigade in the Equancourt district endeavoured after the fall of Fins to fill this front, but they were not nearly numerous enough for the purpose. The result was that the Forty-seventh Division, which moved back on the night of March 22 from Highland Ridge to the Metz-Dessart Wood line, had to reach out more and more upon the right in order to save the situation. In this operation two battalions, the 4th Welsh Fusiliers Pioneers and the 23rd London, sustained most of the attack and suffered very heavily upon March 23, while in the preliminary fighting upon March 22 the 18th London had many losses. By the morning of March 24, the Forty-seventh, beating off all attacks and keeping their position in the unbroken line, had fallen back to a new position, the 142nd Brigade, which formed the rearguard, fighting hard in its retreat, and having to brush aside those groups of Germans who had slipped in at the rear.

Fourth and Fifth Corps. March 24.

The morning of March 24 found the German torrent still roaring forward in full spate, though less formidable than before, since the heavier guns were far to the rear. Their light artillery, trench-mortars, and machine-guns were always up with the storming columns, and the latter were relieved in a manner which showed the competence of their higher command. It was a day of doubt and difficulty for the British, for the pressure was everywhere severe, and the line had frayed until it was very thin, while officers and men had reached the last limits of human endurance. At 8.30 in the morning the enemy was pressing hard upon the Seventeenth and Forty-seventh Divisions in the region of Bus and Le Mesnil, where they were endeavouring to keep in touch with the worn remains of the heroic Ninth Division on the left of the Seventh Corps. Sailly Saillisel was still clear of the enemy, but the tide was flowing strongly towards it. The 51st Brigade of the Seventeenth Division occupied this village and threw out its left to the Londoners on the north of them. Bertincourt, which had become a dangerous salient, was evacuated, and the line now ran east of Haplincourt and Rocquigny, the three brigades of the Seventeenth Division occupying this latter village, Barastre, and Villers-au-Flos. On their north were two brigades of the Forty-seventh, the remaining brigade being south of Le Transloy. North of the Forty-seventh Division the Sixty-third Naval Division and the Second Division carried the line on to the junction with the Fourth Corps, where the exhausted Nineteenth Division lay across the Cambrai Road, with the even more shattered Fifty-first Division at Riencourt to the north of them. There was some very furious fighting in front of Rocquigny about mid-day, in which the 12th Manchesters of the Seventeenth Division, and the three battalions (18th, 19th, 20th London) of the 141st Brigade made a very desperate resistance. The fighting was continued until the defenders found themselves in danger of being surrounded, when they were withdrawn. The 140th Brigade, under Colonel Dawes, also did great service that day in holding the Germans from getting behind the line. The enemy was so far round that there was the greatest difficulty in clearing the transport, which was only accomplished by the fine rearguard work of the 4th Welsh Fusiliers, aided by the 11th Motor Machine-gun Battery, and 34th Brigade R.F.A.
