As already shown the Givenchy bastion was held firm, which meant that the Fifty-first Division was also to some extent helped to resist attack, since an enfilade fire from the Fifty-fifth would beat upon any advance against them. Such advances were repeatedly made upon April 11 and were splendidly countered. North of this point the Fiftieth, Twenty-ninth, and Thirty-first Divisions had all suffered heavily, while the line had been bent back in a curve from the La Bassée Canal to a maximum depth of ten miles, ending on the night of April 12 in a position from west of Merville through the two Berquins to Merris. The Twenty-ninth Division, which is a particularly good comrade in a tight place, had been very hard pressed, with its brigades sent hither and thither wherever a leak was to be stopped. It was in this action that Colonel Forbes Robertson, one of the heroes of Cambrai, earned the coveted Cross by fighting on horseback at the head of his men like some knight of old, and repeatedly restoring the line when it was broken. In spite of all valour, however, the general movement was westwards. Whilst these misfortunes had occurred in the southern sector, others not less serious had occurred in the north, owing to the great extension of the German attack. It is to these that we must now turn.
The enemy had achieved a considerable success upon April 9 when they succeeded in establishing themselves across the Lys at Sailly and Bac St. Maur, because by doing so they had got to the south-west of Armentières. They had prepared another attack in the north, and it was evident that if it had any success the Armentières position would be impossible. Early in the morning of April 10 the usual shattering and pulverising bombardment which preceded a full-dress German attack broke out upon the right of the Second Army, involving the front from the Ypres-Comines Canal in the north down to the Lys River at Armentières, thus joining up with the battle of yesterday, and turning the ten-mile front into one of twenty. The chief points in this line are Hollebeke in the north, Wytschaete in the centre, and Messines in the south, with Ploegsteert Wood and village and Nieppe as the final connecting links with Armentières. It was all classic and sacred ground drenched with the blood of our bravest. There can be few regiments in the British Army which have not at one time or another left their dead upon this shell-pitted slope, or upon the levels which face it.
The order of the Second Army from the north at this time was Twenty-second, Eighth, Second, and Ninth Corps. It was the Ninth Corps (Hamilton-Gordon) which was now attacked. The order of divisions upon this front was Campbell's Twenty-first Division astride the Ypres-Menin Road, the Ninth (Tudor) in the Hollebeke district, the Nineteenth (Jeffreys) covering 6000 yards east of Messines and Wytschaete from Ravine Wood in the north to the Douve in the south, and finally the Twenty-fifth Division (Bainbridge) on the right, which was already in a most unfavourable position, as its right flank was menaced by the driving in of the Fortieth and threat to the Thirty-fourth on the preceding day, while one of its brigades, the 74th, had been taken away to cover Steenwerck from the German advance at Bac St. Maur. It was upon these divisions, and, in the first instance, upon the two southern ones that the new German attack from the Fourth Army of our old enemy General von Armin broke on April 10. It should be remembered that, like so many of their fellow-units, both of these divisions had been very heavily engaged in the south, and that their losses within the last two weeks had been very great. Verily we have travelled far from the day when it was laid down as an axiom that a corps which had lost a quarter of its numbers would not stand to its work until time had effaced the shock.
Since the main assault on April 10 fell upon the Nineteenth Division the story can be most plainly told from their central point of view. The left of their line was held by the 58th Brigade (Glasgow), consisting of the 6th Welsh and 9th Welsh Fusiliers. The right was held by the 57th Brigade (Cubitt) which contained the 10th Warwick, 8th Gloucester, and 10th Worcesters. The 56th (Heath) was in reserve. It was upon these troops that there fell the strain of an attack which can seldom have been exceeded in severity. The total German force on the corps front was eleven divisions, and of these no less than five were directed on the morning of April 10 upon the depleted ranks of General Jeffreys' unit.
A very thick mist prevailed, and through this protective screen the German infantry advanced about 6 o'clock, driving swiftly through all the forward posts, and putting them out of action in exactly the same fashion as on March 21. The enemy were in great numbers, and their advance was swift and resolute. Within half an hour of the first alarm they had made a lodgment in the main position of the 57th Brigade, and had also broken in the face of the left wing of the Twenty-fifth Division to the south. The garrisons of the outlying posts were never seen again, and it was observed that they were greatly hampered by their camouflage screens which they had no time to tear away in the face of so rapid and overwhelming an attack. At 6.40 the enemy were deep in the position of the 57th Brigade, especially near Gapard Spur, which marked the centre of that unit. At 7.30 the whole brigade was in difficulties, which was more marked in the centre than on either flank, but was serious at every point of the line. The 8th North Staffords of the Reserve Brigade were brought up at this hour to help in the defence of this weakening sector. Before they could arrive upon the scene the enemy had made such progress that he had reached the crest of the ridge and had occupied the village of Messines. The 68th Brigade in the north had not yet been attacked, but General Glasgow seeing his right flank entirely exposed had thrown back a defensive line. Close to this line was a post named Pick House, and upon this the mixed elements of the left of the 57th Brigade, chiefly men of the 10th Warwicks, now rallied and formed a strong centre of resistance. The Twenty-fifth Division to the south had been also very hard pressed, and was in immediate danger of losing the important knoll, Hill 63, so that the reserve brigade of the Nineteenth Division had to send the two remaining battalions, the 4th Shropshires and 9th Cheshires, to strengthen their defence. There was thus no longer any support for the Nineteenth Divisional fighting line in their great need, save for the 5th South Wales Borderers, their pioneer battalion, and the 81st Field Company R.E., both of whom were thrown into the battle, the pioneers pushing bravely forward and connecting up with the 10th Warwicks at Pick House. Meanwhile the 8th North Staffords had made a fine attempt to retake Messines, and had actually reached the western edge of the village, but were unable to gain a permanent footing. Their right was in touch with the 8th Gloucesters, and some sort of stable line began to build itself up before the Germans. They had been unable to occupy Messines in force, owing to the rifle-fire which became more deadly with the rising of the mist. The scattered groups of infantry lying upon the ridge on either side of Messines were greatly heartened by the splendid work of A Battery, 88th R.F.A., under Captain Dougall, which remained among them, firing over open sights at the advancing Germans. "So long as you stick it I will keep my guns here!" he shouted, and the crouching men cheered him in return. He was as good as his word, and only withdrew what was left of his battery, man-handling it across almost impossible ground, when he had not a shell in his limbers. This brave officer received the Victoria Cross, but unhappily never lived to wear it.
The 8th North Staffords, still lying opposite Messines, extended their left down the Messines-Wytschaete Road in an endeavour to join up with the men at Pick House. Thus a frail curtain of defence was raised in this direction also. Shortly after mid-day things began to look better, for the gallant South African Brigade (Tanner) of the Ninth Division was despatched to the rescue. So severe had been its losses, however, that it numbered only 1600 bayonets, and had hardly been re-organised into battalions. Late in the afternoon it advanced, the 1st Battalion on the left, 2nd on the right, and though it had not the weight to make any definite impression upon the German front it entirely re-established the line of the road from Messines to Wytschaete, and reinforced the thin fragments of battalions who were holding this precarious front. The South Africans incurred heavy losses from machine-gun fire in this very gallant attack.
The Ninth Division had hardly relinquished its Reserve Brigade when it found that it was itself in urgent need of support, for about 2 o'clock on August 10 the attack spread suddenly to the northern end of the line, involving the 25th, 26th, and 58th Brigades, all under General Tudor, who was now responsible for the Wytschaete front. So infernal was the barrage which preceded the attack, that the right of the Ninth Division in the vicinity of Charity Farm was driven in, and the 58th Brigade, with both flanks in the air and smothered under a rain of shells, was compelled also to fall back upon its support line. About 4 P.M. the 58th Brigade was broken near Torreken Farm, and the 6th Wiltshires, who were the flank battalion on the right, were cut off and lost heavily. The enemy were driving hard at this period towards Wytschaete, but the 9th Welsh stood fast in a cutting to the south of the village, and held the Germans off with their rifle-fire. So ended a most trying and unfortunate day, where the overborne troops had done all that men could do to hold their ground, fighting often against five times their own number. The prospects for the morrow looked very black, and the only gleam of light came with the advent, about midnight, of the 108th Brigade (Griffiths) from the Ulster Division, with orders to fight alongside the exhausted 57th, whose commander, General Cubitt, was now directing the local operations to the west of Messines. The Wytschaete front was also strengthened by the inclusion in the Ninth Division of the 62nd and later of the 64th Brigade of the Twenty-first Division. Farther south the 75th Brigade north of Armentières had been driven back by the enemy's attack, and the 7th Brigade on its left, finding its flank uncovered, had hinged back upon Ploegsteert Wood, where it held its line as best it might. Thus on the left, the centre, and the right there had been the same story of unavailing resistance and loss of valuable, dearly-bought ground. Even more serious, however, than the local loss was the strategical situation which had been created by the German advance in the lower sector, by their crossing the Lys, and by the fact that on the night of April 10 they were closing in upon Steenwerck and La Crêche far to the right rear of the defenders of the Messines line. It was a situation which called for the highest qualities of generals as of soldiers.
By the morning of April 11 General Plumer, dealing out his reserves grudgingly from his fast diminishing supply, placed the 147th Brigade of the Forty-ninth Yorkshire Territorial Division (Cameron) behind the Twenty-fifth Division in the Ploegsteert region, and a brigade of the Twenty-ninth Division to the north of it. Such succours were small indeed in the face of what was evidently a very great and well-prepared attack which had already shaken the whole northern front to its foundations. The Higher Command had, however, some points of consolation. If the vital sectors could be held there was the certainty that strong reinforcements would arrive within a few days from the south. The Amiens line was now certainly stabilised, and if once again an equilibrium could be secured then the last convulsive efforts of this titanic angel of darkness would have been held. With no illusions, but with a dour determination to do or die, the British line faced to the east.
The immediate danger was that a gap had opened between Messines and Wytschaete, while another was threatened farther south between Ploegsteert and the Nieppe-Armentières Road. The pressure upon the Damstrasse was also very great in the region of the Ninth Division. The first disposition in the Messines area was to strengthen the line of resistance by pushing up the three battalions of the 108th Brigade, the 1st Irish Fusiliers on the left near Pick House, the 9th Irish Fusiliers west of Messines, and the 12th Irish Rifles in the Wulverghem line. The attack on the morning of April 11 was not heavy in this direction, but was rather directed against the Twenty-fifth Division in the Ploegsteert district, where it came ominously close to Hill 63, a commanding point from which the Messines position of the British would be taken in reverse. General Jeffreys of the Nineteenth Division determined none the less to stand his ground, but he threw out a defensive flank along the Messines-Wulverghem Road, and mounted machine-guns to hold any attack from the south. Meanwhile the 57th, South African, and 108th Brigades, in spite of this menace to their right rear continued to hold the Messines front. There was severe fighting on this sector during the afternoon in which the remains of the 2nd and 4th (Transvaal Scots) Battalions were pushed back for some distance, but counter-attacked under the lead of Captain Green, regaining most of the ground that they had lost, and connecting up with the 5th South Wales Borderers, who were still holding fast near Pick House. This line was maintained until the general withdrawal. It was further strengthened by the 146th Brigade, one of the three units of the Forty-ninth Division, which were all engaged at different points. One battalion, the 7th West Yorkshires, called on suddenly to fill a gap, made a very fine advance under heavy fire, and restored the situation. It remained in the line until, on April 16, it was almost annihilated by a terrific German attack upon it.
