A British corps does not allow itself to be driven without hitting back, however great the odds may seem. A series of brisk skirmishes was going on all along the line. In one of these, just south of Ham, Colonel Watson with the 17th King's Liverpools came back on his pursuers and held them up for a time. More serious was the counter-attack organised by the main body north of Esmery-Hallon. This attack struck southwards from Canizy and hit upon the right flank of the Germans, staggering them for the instant. It was carried out by the 60th Brigade and the 182nd Brigade, all under General Duncan of the former unit. This spirited advance was led upon the field by Colonel Bilton of the Sixty-first Division, and was delivered with such force that this small British detachment drove back for some distance the great army which was rolling westwards. It was impossible, of course, to recover ground permanently, but it gained invaluable time and eased the pressure upon the south end of the line for the whole of a critical evening. It was clear, however, that the capture of Ham and the crossing of the stream had turned the flank of the Twentieth and Sixty-first Divisions, who were defending the higher reaches of the same river. They were not to be frightened prematurely out of their positions, however, and at Bethencourt the 11th Rifle Brigade drove back a German attempt at crossing, while at Offoy the 12th Rifles also inflicted a sharp repulse upon the pursuers. That evening, March 23, the Sixty-first Division was practically amalgamated with the Twentieth, and both were concentrated near Nesle. They received at this time a most useful reinforcement in the shape of two batteries (16 guns) of Canadian motor machine-guns under Captain Meerling. There is not an officer or man of these much-tried battalions who would not admit a deep debt of gratitude to these splendidly efficient and energetic guns, which had such mobility that they were always where they were most wanted.

March 24.

The troops had on the morning of March 24 got behind the Somme Canal, which runs beside the river, all bridges had been broken, and patrols were pushed across where practicable so as to keep in touch with the enemy. It was not in this southern area, however, but at Bethencourt that the Germans did actually get across in force, by which they turned the flank of the 25th Brigade of the Eighth Division in the north and of the 59th Brigade in the south. An attack was instantly organised by the 11th Rifle Brigade, who had lost their Colonel, Cotton, the day before, and were now led by Major Bertie. They succeeded by a fine effort in driving the Germans for the time across the canal and gaining touch with the Eighth Division. The Germans pushed across once more at Pargny, upon the other flank of the Eighth Division, and also renewed their attempt in greater force at Bethencourt, getting possession of the higher ground there. This time it was the Highlanders and Royal Scots of the 183rd Brigade who counter-attacked, acting as part of the Twentieth Division, and by half-past two in the afternoon the position had once more been re-established. The Canadian motor-guns were invaluable in this operation.

Upon the morning of March 24 the Sixty-first Division was barring the road from Ham to Nesle. The German progress had been checked in this direction by a spirited counter-attack carried out by the 5th Cornwalls, the pioneer battalion of that division, together with a mixed array of police, bandsmen, and other details, who advanced from Offoy to a depth of five miles, under Major Bennett. This little improvised force held on all night, and seems eventually to have joined up with the French in the neighbourhood of Esmery-Hallon.

The British were still holding the crossings at Voyennes and Offoy, but very hard fighting had broken out to the south, and the Germans, who had poured over in the neighbourhood of Ham, were now thrusting hard for Canizy. The road bridges had all been destroyed, but there was a railway bridge at Ham which had been taken out of the hands of the army authorities and left in charge of the railway department. This was either uninjured or at any rate inadequately destroyed, and was of immediate use to the enemy, enabling him to keep uninterrupted pressure upon the retiring troops. Canizy was now taken, but the 12th Rifles made an immediate counter-attack and forced the Germans back from the village. In this spirited operation they lost their gallant Colonel, Moore, who had led them with the utmost fearlessness.

Whilst the Germans were pushing forward at Canizy they had also maintained strong and continuous pressure upon the Thirtieth Division near Moyencourt, and upon the Thirty-sixth Division at Golancourt, causing the Ulster men, whose left wing was entirely in the air, to fall back westwards. The next line of defence, after the Somme had been forced, lies along what is called the Libermont Canal between Nesle and Libermont. It was necessary to fall back, fighting as best they could, and to place this obstacle, narrow as it was, between the weary soldiers and their pursuers. It was the third day since the men had had a decent meal or an uninterrupted rest, and they were very disorganised and broken. "Hundreds of men were streaming back," says one observer. "They had been without food for days and were done in completely. They were stopped and reformed at the bridges, where as many as 2000 were collected." It is such plain sobering sentences which help one to realise that war is not, as large scale descriptions might seem to imply, a question of the moving of pieces upon a board, but that underneath the strategy lie the countless human tragedies, the tortured frames, the broken nerves, the prayers of brave men that they may still be brave, the torturing anxiety of officers, the ever-pressing burden which sometimes breaks the weary back which tries to hold it. Strategy reckons nothing of these things, but their accumulation makes up the terrible human tragedy of war, which brings humility to the most proud and fear to the most valiant. All equally feel the weakness of nature, but he is blessed who has the strength of spirit to cover and to combat it.

By mid-day on March 24 the Thirtieth Division was over the Libermont Canal, holding from Buverchy to Libermont, with the village and bridge of Raincourt as a joining point between the 90th Brigade to the north and the 89th to the south. It may be recorded, to descend suddenly from divisions to individuals, that the first sign of the new German advance was a single scout who appeared in the open in front of the canal, and was engaged in a prolonged and deliberate rifle duel by Lieutenant Harrop, with the result that he was finally brought in as a wounded prisoner. The Twentieth Division had also fallen back, the orders of brigades from the south being the 60th with its flank on Buverchy, the 59th resting on Quiquery, and the 183rd to link up with the Eighth Division near Mesnil St. Nicaise. The Thirty-sixth Division prolonged the line to the south of Libermont. The French reinforcements from the south were beginning by the afternoon of this day to get as far north as this section, and if not very weighty at the moment they were of great moral use as a promise for the future.

From the new positions of the British line the German infantry could now be seen advancing in platoon columns in three lines on each side of the Voyenne Road and heading for the Libermont Canal. Several parties of horsemen could be seen also, who were conjectured to be battery staffs, keeping up with the fight. The weak point was still near Bethencourt, between the Twentieth and the Eighth Divisions, where the gap tended to be wider as the enemy got more troops across and endeavoured to push the 25th Brigade north as has been described in dealing with the experiences of the Nineteenth Corps. They were reported before evening as having got as far as Morchain. The flank brigade of the Eighteenth Corps, the 183rd, was ordered to extend as far to the north-west as Potte in the hope of regaining touch, but though they reached that village they were still unable to bridge the gap. During the night there were heavy attacks upon Mesnil St. Nicaise in this region, which fell chiefly upon the Rifle battalions of the 59th Brigade, which had been reinforced by the 20th Entrenching Battalion and the 11th Durhams, the divisional pioneer battalion. The general result was to force the British line some little distance to the westward. At Buverchy in the evening the German infantry also advanced in great numbers, but came under the very efficient guns of the Thirtieth Division, and lost very heavily. The enemy artillery was also very active so that both the Thirtieth near Buverchy and the Thirty-sixth farther south had many casualties. The French relief was making itself more felt, however, in this southern section, where they were already outnumbering the British. The latter were greatly worn—so much so that the 21st Brigade of the Thirtieth Division could hardly be said to exist, only about 100 of the Yorkshires being left in the line. By evening the centre of the position was near Moyencourt, some little distance to the west.

March 25.

In spite of the French reinforcements, which were not accompanied with artillery, the attack was still markedly stronger than the defence, so that March 25 was a most dangerous and critical day in this quarter of the field. To trace the developments from the north the enemy continued to press through the gap between the two corps, the Nineteenth and the Eighteenth, making a series of heavy attacks towards Mesnil-le-Petit and Nesle from the direction of Potte. This movement, powerfully followed up, pushed back the left flank from Quiquery to a point on the high ground 1000 yards west of Nesle. The 183rd Brigade, which was now a mere handful of Scottish infantry, superb in quality but reduced to the last stage of exhaustion, together with the thin ranks of the 59th Brigade of Rifles, could not, even with the aid of the Canadian motor-guns, hold the heavy masses who pressed down upon them. The French One hundred and thirty-third Division moving up in support had dug a line between Billancourt and Herly, but Nesle was abandoned to the enemy, the Twenty-second French Division retiring from this sector and falling back towards Roye. The 60th Brigade of the Twentieth Division, much helped by the 23rd Entrenching Battalion—these valiant diggers made their presence felt all along the line—still held stoutly to their positions from Quiquery to Buverchy, but their left and left rear were so compromised that it was clear they could not hold out longer. To the south the French, who had relieved the Thirty-sixth Division at Libermont, had been pushed back, and the British position was turned in their direction also. By the afternoon the French had taken over the line as far north as Buverchy, and the Thirtieth Division was ordered to fall back, but the Germans had advanced so rapidly from Libermont and got so far to their right rear that it was no easy matter either for the British or the French to get past them. Many had to swim the canals which striate this part of the country, and the 2nd Bedfords were especially hard-pressed before they were able to get away. The Twenty-second French Division was doing all it could to cover the approaches to Nesle upon the south, and the 184th Brigade cheered them loudly as they passed through their ranks. "They looked very fine men and seemed very much for it." General Wetherall of this brigade was badly wounded by a shell splinter in this period of the battle. And we have a vivid pen-picture drawn by a spectator of Brigade-Major Hewitt, some of whose adventures have already been recorded, holding Wetherall's wounded artery with one hand, while he wrote brigade orders with the other, for more than two hours on end. The 184th lost five commanders during the retreat.
