Seventh Corps. March 24.
In the morning of March 24 the Scots could see the German infantry streaming forward over the open ground which had been evacuated upon the evening before. It was clear that a great attack was imminent, and at 9 o'clock, after a very heavy cannonade, it developed along the whole line. For three hours the Germans made repeated efforts to force their way through the Ninth Division, but on each occasion they were repulsed, and their losses at this point were exceedingly heavy. About mid-day, however, they had gained so much ground upon the flanks that the South Africans were almost surrounded, and shot into from north and south. The general British line had fallen back to the ridge east of Combles, 1000 yards behind, but General Dawson found it impossible to withdraw in daylight, so that his brigade was compelled to defend itself in its isolated position at Marrières Wood as best it could. The result was a disaster, but one of a most glorious kind, for the men fought until their last cartridges had been expended, and a large proportion of the survivors were wounded men. General Dawson was among the prisoners. It was reported afterwards from German sources that he was taken while working a machine-gun with his brigade-major lying dead beside him. The whole defence was said by the Germans to have been one of the finest things in the war. From that time forward the South African Brigade had practically ceased to exist until it was reorganised in Flanders. The supporting parties alone were left, and these were formed at once into a composite battalion under Colonel Young, for no rifle could be spared from the fighting line at such a time. Whilst the South Africans had been engaged in this death struggle the 27th Lowland Brigade had been in a similar plight. All these battalions, the 6th Scots Borderers and the 11th and 12th Royal Scots, were very hard pressed, particularly the former. The Lowlanders extricated themselves from an almost desperate situation and fell back from St. Pierre Vaast to the position covering Combles. So great was the general dislocation of troops that one portion of the 5th Camerons found themselves that evening fighting with the Forty-seventh Division, while another was with the Seventeenth.
The main effort of the enemy upon March 24 was directed against the Fifth and Seventh Corps in the centre of the British line, though his energy at other points was sufficient to engage the full attention of all the other units. Heavy and fresh masses were poured in at the centre and the pressure was great. For the Seventh Corps it was the fourth day of incessant and desperate fighting. There were few men left, and these were very exhausted. Towards evening the left of the Seventh had been turned, and had been compromised by the occupation of Sailly Saillisel. All attempts at counter-attack, however gallant, were destined to failure, or at the best evanescent success, for there was not the weight to carry them through. At 4.15 the report was: "The enemy is through on the right flank and has occupied Combles, Morval, and Lesbœufs." The Seventh Corps then fell back to the line Hem-Maurepas and threw out every stray unit it could get together—troops of cavalry, Canadian motor-guns, crews and machine-guns of tanks, and all the powdered débris of broken formations, in the direction of Bernafoy Wood to cover the exposed flank. It was still out of touch with the Fifth Corps. This movement gave the line an awkward angle from Peronne and made it almost impossible to hold the stretch of river. For the time the right of the Third Army was a good five miles behind the left of the Fifth Army—the result, as Sir Douglas Haig has stated, of an unauthorised local withdrawal due to misunderstanding of orders. The line near Peronne was still held by the Thirty-ninth Division. Throughout the morning of the 24th strong enemy forces were seen by them pushing forwards between Clery and Rancourt, where they were harassed by the British fire in enfilade, particularly on the roads, where the artillery of the Sixteenth and Thirty-ninth Divisions caused much havoc and confusion, doing great work at short range over open sights. Many excellent targets were missed, however, owing to that difficulty in liaison between the infantry and the guns, which was one of the greatest problems of the operations. During the day the average number of rounds fired per battery was 3000, most of which were observed fire.
As March 24 wore on the position of the Thirty-ninth Division became untenable, as they heard upon one side of the loss of Saillisel, and on the other of the forcing of the Somme at Brie, Pagny, and Bethencourt. They moved back, therefore, at night with orders to hold the line from Buscourt to Feuilleres. The average strength of brigades at this time was not more than 20 officers and 600 men. From the morning of March 25 the Thirty-ninth Division passed to the command of the Nineteenth Corps, and its further arduous work will be found under that heading. During all this day Campbell's Twenty-first Division, still fighting hard in a succession of defensive positions, had its right upon the Somme, while its left was in intermittent touch with the Ninth Division.
The Ninth Division had fallen back, the two Scottish brigades being continually in action until they reached the Maricourt-Montauban line, where they supported the First Cavalry Division who were in front of Bernafoy Wood. The general line at this period from Montauban southwards was held by the Ninth Division, the First Cavalry, the newly-arrived and most welcome Thirty-fifth Division (Franks), the Twenty-first Division, now reduced to a single composite brigade under General Headlam, and then some oddments under Colonel Hunt. This brought the line to the Somme, on the south side of which were the remains of the Sixteenth and Thirty-ninth Divisions. This might sound an imposing force upon so short a front, but save for the Thirty-fifth each division was nominis magni umbra, none of them stronger than brigades. The Forty-seventh Division was retiring at this time upon Contalmaison, and a gap of several miles was appearing between the Fifth and Seventh Corps. During the movements upon March 24 the guns of the 65th and 150th R.F.A. did great work and earned the warm gratitude of the weary infantry. The enemy targets round Combles were all that a gunner could wish.
All troops north of the Somme were upon March 25 transferred to the Fifth Corps, and became part of the Third Army. The 27th Brigade was drawn out of the line, and the 26th was under the orders of the Thirty-fifth Division which took over the defence of this sector, relieving the exhausted Twenty-first Division. March 25 saw heavy attacks on Bernafoy which was lost once, but regained by the 106th Brigade. There was still a gap to the north, and no touch had been made with the Seventeenth Division, though the cavalry had built up a defensive flank in that direction. At 2 P.M. the Germans attacked from Ginchy towards Trones Wood, names which we hoped had passed for ever from our war maps. In the first onset they pressed back the 12th and 18th Highland Light Infantry of the 106th Brigade, but there was a strong counter-attack headed by the 9th Durhams which retook Favière Wood and restored the situation. A second attack about 3 P.M. upon the Thirty-fifth Division was also repulsed. The German pressure was so great, however, that the line of defence was taken back during the night to the Bray-Albert position. The enemy followed closely at the heels of the rearguards, though the guns were active to the last so as to conceal the retreat as long as possible. Early in the morning of March 26 the Lowland Brigade was again attacked with great violence, but the 12th Royal Scots, upon whom the main assault fell, drove it back with loss. Changes in other parts of the line, however, necessitated a withdrawal across the Ancre, so as to keep in touch with the Twelfth Division which had now come up on the left. The Ninth Division upon this date numbered 1540 rifles with 20 machine-guns. It was shortly afterwards drawn from the line after as severe a spell of service as troops could possibly endure. The story of the retreat of the Seventh Corps has been indicated mainly from the point of view of this northern unit, but it will be understood that the Twenty-first, as tried and as worn as its Scottish neighbour, was keeping its relative position to the south, while the Sixteenth was conforming in the same way until the time when it passed into the Nineteenth Corps.
The Thirty-fifth Division, newly arrived from Flanders, did great and indeed vital work in upholding the weakening line at the moment of its greatest strain. A consecutive account of its work may make this clear. Pushing through the remains of the Twenty-first Division on March 24, Franks threw his men instantly into the thick of the fight, attacking the Germans in front of Clery. Marindin's 105th Brigade did great work that day, the 15th Cheshires on the right and 15th Sherwood Foresters on the left, attacking and, for a time, carrying the ridge of Clery, though it was impossible in view of the general retreat to hold it for long. The Germans were staggered by the sudden, unexpected blow, and they poured troops against their new antagonist, losing very heavily in their reconquest of the ridge. Finally the front line of the Sherwoods was practically annihilated, and the Cheshires were in almost as bad a way, but with the help of some Sussex men who were formed into an emergency unit, together with some signallers, they were able to draw off, and a line of defence was organised under General Marindin, but general orders arrived for a withdrawal to the front Curlu-Maurepas, which was safely carried out, the 17th Royal Scots covering the rear. It was a most ticklish business, as touch had been lost with the Ninth Division, but the wounded were safely evacuated, and all withdrew in good order, the 12th Highland Light Infantry finally bridging the gap upon the left. This battalion had lost in these operations its splendid Colonel, Anderson, whose work has earned a posthumous V.C. The enemy followed closely, and attacked again before dusk, but was driven off. The attack was renewed on the morning of March 25, but still without success, the 4th North Staffords bearing the brunt. The weary troops of the Scottish division, who had been engaged for four long days, were rallied here and formed into provisional fighting units, which did good service by relieving the 106th Brigade at Maricourt, when it was forced back. The pressure upon the division was desperately severe, but was slightly eased by the arrival of a Northumberland Fusilier battalion from the Twenty-first Division. That night the order was to withdraw to the line Bray-Albert.
Seventh Corps. March 25. March 30.
The general command of the retiring line in this section, including the Ninth, Twenty-first, and Thirty-fifth Divisions had for the time fallen to General Franks, who handed his own division over to General Pollard. The position was exceedingly critical, as not only were the units weak, but ammunition had run low. The line was still falling back, and the enemy was pressing on behind it with mounted scouts in the van. In this retreat tanks were found of the greatest service in holding the German advance. The route was through Morlancourt and Ville-sur-Ancre to a defensive position upon the right bank of the Ancre in the Dernancourt area, the orders being to hold the line between that village and Buire. Both villages were attacked that evening, but the Thirty-fifth Division on the right and the 26th Brigade on the left, drove back the enemy. By the morning of March 28 the line seemed to have reached equilibrium in this part, and the welcome sight was seen of large bodies of troops moving up from the rear. This was the head of the Australian reinforcements. During the day the enemy got into Dernancourt, but was thrown out again by the 19th Northumberland Fusiliers Pioneer Battalion. The 104th Brigade also drove back an attack in front of Treux Wood. It was clear that the moving hordes were losing impetus and momentum. That same evening the Australians were engaged upon the right and inflicting heavy losses on the enemy. On the night of March 30 the Thirty-fifth Division, which had lost nearly half its numbers, was relieved by the Third Australians.
