We shall now follow the Nineteenth Corps in its perilous retreat. It will be remembered that on the evening of the first day of the battle it had been badly outflanked to the north, where the Sixty-sixth Division had made so stout a resistance, and had also lost a great deal of the battle zone in the south, which was made more disastrous by the fall of Le Verguier at nine on the morning of March 22. The supporting line formed by the Fiftieth Division had also been pushed in at Pœuilly and other points, and it was with no little difficulty that the depleted and exhausted corps was able to get across the Somme on the morning of March 23, where they were ordered to hold the whole front of the river, including the important crossings at Brie. This, as a glance at the map will show, was a very considerable retreat, amounting to no less than ten miles in two days, but it was of the first importance to get a line of defence, and also to lessen the distance between the sorely tried army and its reserves. It was hard indeed to give up ground and to be back on the line of Peronne, but there was at least the small solace that this was the ravaged ground which the Germans had themselves turned into a waste land, and that there was no town of any consequence nor any military point of importance in its whole extent.

By the late afternoon of March 23 the bulk of the Nineteenth Corps was across the Somme. The Germans had followed closely, and there was rearguard fighting all the way in which the Fiftieth Division slowed down the pursuit of the enemy. The officers who were entrusted with the defence of the line of river soon realised that they had a difficult task, for the dry weather had shrunk it into insignificance in this section, and owing to trees and thick undergrowth the fields of fire were very limited, while the thin line of defenders scattered over some twelve miles of front offered, even after the advent of the Eighth Division, an ineffective screen against the heavy advance from the east. Heneker's Eighth Division, a particularly fine unit consisting entirely of Regular battalions, had made heroic exertions to reach the field of battle, and fitted itself at once into its correct position in that very complicated operation in a way which seemed marvellous to soldiers on the spot.

In the evening of March 23 a number of Germans, some of them cavalry, were observed upon the farther side of the Somme and were heavily punished by artillery fire. None got across before dark, but during the night numerous bodies established themselves upon the western side. Local reserves had been placed near the probable crossings, and these in several cases hunted the enemy across again; but the fact was that the river could be forded anywhere, and that a German concentration on a given point could always overpower the thin local defence. The line of resistance was further weakened by the First Cavalry Division, which had linked up the Nineteenth Corps with the Eighteenth Corps on the south, being now ordered to join the Seventh Corps in the north. The general order of the troops at this moment was, that the newly arrived Eighth Division was on the extreme right touching elements of the Eighteenth Corps at Bethencourt and extending with the aid of one brigade of the Fiftieth as far as Eterpigny, nearly eight miles. From Eterpigny to Biaches, south of Peronne, were the remains of the Sixty-sixth Division, covering about four miles, and joining the Thirty-ninth Division on the right of the Seventh Corps near that point. The Twenty-fourth was lining up between Hattencourt and Chaulnes.

Nineteenth Corps. March 24. March 25.

It was on the front of the Eighth Division, at Bethencourt, at Pargny, and at St. Christ, that the Germans made their chief lodgments upon the western banks of the river on the morning of March 24. The Bethencourt attack was particularly formidable, both for its energy and because it aimed at the junction of the two corps. By two in the afternoon the German infantry were across in considerable numbers, and had forced back the right flank of the Eighth Division, which fell back hinging upon the river farther north, so as to oppose the repeated efforts which were made to enfilade the whole line. General Watts' responsibilities were added to next morning, March 25, for the two much exhausted divisions of the Seventh Corps which were holding the northern bend of the river from Biaches to beyond Frise were handed over to him when the rest of Congreve's Corps was incorporated in the Third Army. These two divisions were the Thirty-ninth and the Sixteenth, the former holding as far as Frise and the latter the Somme crossings to the west of that point. March 25 was a day of great anxiety tor General Watts, as the enemy were pressing hard, many of his own units were utterly exhausted, and the possibilities of grave disaster were very evident. A real fracture of the line at either end might have led to a most desperate situation. The French were now at the south end of the river position, but their presence was not yet strongly felt, and with every hour the pressure was heavier upon the bent line of the Eighth Division, on which the whole weight of the central battle had fallen. By 10 o'clock on the morning of March 25, the defensive flank of the Eighth Division had been pushed back to Licourt, and had been broken there, but had been mended once more by counter-attack, and was still holding with the aid of the Fiftieth. The cyclists of the Nineteenth Corps, the armoured-car batteries, and other small units were thrust in to stiffen the yielding line, which was still rolled up, until after one o'clock it lay back roughly from Cizancourt to Marchelepot and the railway line west of that place. Later in the day came the news of fresh crossings to the north at St. Christ and Eterpigny where the Sixty-sixth Division had been pushed back to Maisonette. It was evident that the line was doomed. To stay in it was to risk destruction. At 4.15 the order was given to withdraw to a second position which had been prepared farther westward, but to retain the line of the Somme as the left flank. During these operations the Eighth Division had performed the remarkable feat of holding back and defeating fourteen separate German divisions during thirty-six hours on a nine-mile front, and finally withdrew in perfect order. Every unit was needed to cover the ground, and the general disposition of divisions was roughly as drawn:

Hattencourt. Estrees. Herbecourt.
Chantres. Assevillers. Frise.
R. 24 8 50 66 39 16 L.

It will be seen that General Watts' command had increased from two divisions to six, but it is doubtful whether the whole six had the normal strength of two. The new line had not yet been completed and was essentially unstable, but none the less it formed a rallying point for the retreating troops. It should be noted that from the morning of March 25 General Fayolle took over the command south of the Somme.

The Twenty-fourth Division, which had suffered so severely in the first two days of the action, was again heavily engaged during this arduous day. In the morning it had been directed to counter-attack in the direction of Dreslincourt in co-operation with the French Twenty-second Division. In the meantime, however, the whole situation had been changed by the right flank of the Eighth Division being turned, so that General Daly's men as they went up for the attack were themselves heavily attacked near Curchy, while the junction with the French could not be made. They fell back therefore upon their original position where hard fighting ensued all day, and a most anxious situation developed upon the southern flank, where a wide gap existed and the enemy was mustering in force. Colonel Walker, C.R.E. of this division, was killed that day.

Nineteenth Corps. March 26.

On the morning of March 26 the new line had been occupied. The Seventeenth Corps had retired in the night to the Bray-Albert line, which left a considerable gap in the north, to the west of Frise, but this was filled up by an impromptu line made up of stragglers and various odds and ends from the rear of the army. It was in the south, however, that the attack was most severe, and here it soon became evident that the line was too long and the defenders too weak, so that it could not be maintained against a determined assault. Before the sun had risen high above the horizon it had been shaken from end to end, the Twenty-fourth Division being hard put to it to hold Fonches, while the Sixty-sixth were driven out of Herbecourt. At 9.30 the order was given to withdraw, and with their brave rearguards freely sacrificing themselves to hold back the swarming enemy, the troops—some of them in the last stage of exhaustion—fell back upon a second position. It was at this period of the battle that Major Whitworth, the gallant commander of the 2/6 Manchester's, stood at bay with his battalion, which numbered exactly 34 men. He and 17 of his men were dead or wounded after this last stand, and 17 survivors were all that could be mustered that evening.
