Even if the local pressure had not caused a rapid withdrawal at this portion of the line, it would have been enforced by the general strategic position, for the German advance in the south had been so masterful that on this night of March 25 Roye was taken, which is far to the south-west of Nesle. The 61st Brigade had been sharing the hard fortunes of the Thirty-sixth Division, but now, as the latter had been drawn out, it was restored to the Twentieth Division. So severe had been the strain upon it that it only numbered about 500 bayonets, and some battalions, such as the 2/6th Royal Warwicks, had not a single combatant officer left standing. None the less, it was at once sent to man a supporting line stretching through Gruny, Cremery, and Liancourt, and had hardly reached it before the Germans were also at Liancourt. The brigade held them, however, and so enabled the front line to fall back upon an organised position whence, on the next morning, a swift retreat became necessary.
After dark on March 25 the One hundred and thirty-third French Division had come up to relieve the Twentieth and Sixty-first, but the situation was such along the line of the Nesle Canal that no fixed line could be formed, and the three divisions were finally greatly mixed up in the darkness and there was a good deal of confusion in their councils, since the general directions of the French were to fall back to the south, while the line of retreat of the British lay rather to the west. There was little time for deliberation, for word had come in that the Germans were closing in upon Liancourt, pressing south and west, in a way which threatened to cut off the whole forward line. At midnight, the British, many of them hardly able to move for fatigue, staggered off in such formations as they could assemble, with orders to concentrate north and east of Roye. Thanks largely to the presence of the remnants of the 61st Brigade near Liancourt, this most hazardous march was successfully accomplished, but as Roye was within the grasp of the enemy the movement was continued so as to reach a line between Hangest and Le Quesnel. The Germans were close upon them in the north, so the 61st Brigade, now down to 400 men, acted as flankguard, fending off their constant attacks. The war has shown few finer instances of disciplined and tenacious valour than in the case of the three handfuls of men who represented what had once been the 12th King's, 7th Somersets, and 7th Cornwalls. The enemy were in Liancourt, and their patrols were in actual hand-to-hand fighting with a French detachment aided by some of the Somersets. Other German troops pouring down from the north and using to the utmost the gap which had opened between the corps, endeavoured to cut in and to seize Le Quesnoy (not to be confused with Le Quesnel towards which the troops were marching). It was, however, upon their line of retreat, and about halfway to their destination, so that a German occupation would have been serious. The post was most desperately defended by Captain Combe, the brigade-major of the 61st Brigade, with two Lewis guns and 100 men. Only eleven were left standing at the end of this defence, but the village was held for the necessary time, and the survivors only withdrew upon receipt of a positive order. Thus the flank march of the British from Roye to Le Quesnel upon the morning of March 26 was successfully accomplished, owing to the devotion of their covering party to the north. "It was very much of a rabble," says an officer, "and there was great difficulty in sorting out the men and arranging the units." None the less the future was to show that the force was no more beaten than were the old contemptibles after Mons.
March 26.
The Thirtieth Division had been drawn out of the line on the arrival of the French, but they were hardly started on their movement towards the rest which they had earned so well, when this great pressure arose, and every man who could still carry a rifle was needed once more in the line. On the morning of March 26 they were back then, between Bouchoir and Rouvroy. The 21st Brigade had now entirely disappeared, but the remains of the 2nd Yorks and the South Lancashire Pioneer Battalion were added to the 89th Brigade which was in the north at Rouvroy, while the 90th, under General Poyntz, filled the gap to Bouchoir. The Thirtieth Division had got considerably to the west of this line before they were recalled, and it was only by some splendid marching that they were able at last to throw themselves down upon the coveted ground before the German armies, which were streaming along the Roye-Amiens road, were able to reach it. As they faced the Germans the Twenty-fourth, now the mere shadow of a division, was on their left at Warvillers, while the Sixty-first and Twentieth were in support at Beaufort and Le Quesnel. Near Erches the Thirty-sixth Ulster men, whose relief, like that of the Thirtieth, had proved to be impossible, were still battling bravely, retaking the village of Erches after it had fallen to the enemy. The 109th Brigade also distinguished itself greatly in this area, the Irish Fusiliers Battalions of which it is composed holding on most desperately to the village of Guerbigny, at the extreme south of the corps front, and continuing a heroic defence during March 26, and long after it was isolated upon March 27. The artillery of the Ulster Division was particularly good in its covering fire during these operations, gaining the very grateful acknowledgments of the French troops and generals who were more and more concerned with this southern sector of the line. Speaking generally the troops had now reached the region of the old French trenches, which grid-ironed a considerable area of country, so that it was certain that if men could be found to man them, the pursuit would no longer continue at the pace of the last two days.
Great work was done at this period by four of the Canadian motor-guns at the cross-roads, north-west of Rouvroy, where they not only inflicted heavy losses upon the enemy but delayed his advance while the exhausted troops were settling down into this new position. Every hour was of importance as giving reinforcements time to come up from the rear, and the general orders to the divisional generals were to hold on at all costs wherever defence was possible. A small body of corps cyclists under Lieutenant Quartermain co-operated splendidly with the motor-guns and did good service at this critical period of the retreat, during which there was very little artillery support behind the thin line of infantry.
March 27.
The German pressure on March 27 fell chiefly, as already shown, upon the Twenty-fourth Division and the other units on the extreme south of the Nineteenth Corps, which were forced back for some distance, and so threatened the stability of the line in the south. The 17th King's Liverpool, which was the flank battalion, held fast, however, and flung back their left to form a defensive line to the north. A small body of German cavalry performed a brilliant piece of audacious work in the darkness of the early morning of this date, pushing through the outposts of the Thirty-sixth Division in the south near Guerbigny, and capturing the Brigade Headquarters of the 109th Brigade, and also the chief staff officer of the division.
The future was full of menace, for the Germans were pressing on in great numbers. An observer near Bouchoir that evening (March 27) says: "I have never seen so many Germans in all my life—one huge dark mass about a mile away. With glasses one could see howitzers, machine-guns, trench-mortars, and field batteries, as well as infantry. It was a most wonderful sight. They seemed to be coming down the Roye Road, then moving off to the south, and some stopping in a mass."
The main German attack upon the extreme south of the corps line on March 27 fell upon the Thirty-sixth Division in the direction of Erches, with the result that the Ulster men fell slowly back upon Arvillers, the 60th Brigade throwing back a defensive flank to correspond. By 12.30 Bouchoir, held by the 90th Brigade, was gained by the Germans, but the British formed a new line to the immediate westward of the village. An attack upon Folies was thrown back by the 59th Brigade. Towards evening some order came out of a rather tangled position, which may well be obscure both to writer and reader, since soldiers upon the spot found the greatest difficulty in separating the various confused elements. As night fell upon March 27 after much desultory and inconclusive local fighting, there was no great change in the British line which ran from Warvillers, still held by the Twenty-fourth Division, to the west of Bouchoir, where the Thirtieth held the line, and down to Arvillers held by the 60th Brigade of the Twentieth Division, which was temporarily out of touch with the Thirty-sixth Division. Hangest was held by the Sixty-first Division, and Le Quesnel by the Sixty-first and the French. That night the Twentieth Division was ordered to join the Nineteenth Corps, and their record under this new command will be found in the preceding chapter. One would have thought that they had reached the limits of human endurance, and their total numbers were not more than a thousand, and yet they were but at the beginning of a new chapter in their glorious history. The same words apply to their comrades of the Sixty-first Division, who were also ordered north. They were relieved by the French at Arvillers, and this portion of the line was on March 28 pressed back to the west of Hangest.
