In the trenches the mud and the artillery fire were the most serious foes. The German infantry could easily be held. There was one counter-attack on the 8th, on the extreme left. Our bombing squads moved up and drove the enemy out. On the 10th the II. Corps on the right attacked to establish itself upon the Black Line, the artillery covering the 36th Division co-operating. The attack was in the main successful, and the way was prepared for a further advance. On the night of the 14th the troops of the 107th Brigade, then in front line, were relieved, and those which were to carry out the attack moved up, picking up their bombs and special equipment at battle stores previously established as far forward as possible, past which the platoons moved slowly in single file.

The final objective of the 36th Division was from a point on the Zonnebeke-Langemarck Road near Gallipoli Copse, on the right, to Aviatik Farm on the left. This was represented by a series of strong concrete forts, and known as the Red Line. The 16th Division was attacking on the right and the 48th Division on the left of the 36th. The attack of the 36th Division was to be made by the 108th Brigade on the right and the 109th Brigade on the left, with the 107th Brigade in reserve. Each Brigade was to attack with two battalions in front line, one in support, about a thousand yards in rear, and one in reserve, in the old British front and support lines. Each battalion was to attack on a two-company front, in four waves. The second and fourth waves were to be only half the strength of the first and third, owing to companies having been reduced for the time being to three platoons. The objective of the leading companies was the line Gallipoli-Schuler Farm, the old Green Line of the first offensive, still so-called. On this line the rear companies were to pass through to the final objective, the original leading companies following in close support. The supporting battalions were then to move up and take over the Green Line. A company from each of the supporting battalions was allotted to the leading two battalions on each brigade front as "moppers up." Special platoons were given as their objectives such concrete strongholds as Somme, Pond Farm, Hindu Cott, Green House, Schuler Farm. Four guns of each of the Machine-Gun Companies of the attacking brigades were to go forward with the infantry, the remainder being used for the barrage. No Stokes mortars could be taken forward owing to the state of the ground. The task of the R.E. was the consolidation of the Dotted Green Line. This was to be a defensive system on our side of the wire running from Gallipoli Copse through Green House, using that obstacle for our own purposes. That of the Pioneers was the clearance of the Wieltje-Gravenstafel Road.

The field artillery, under the orders of General Brock, the C.R.A., consisted of the 36th and 61st Divisional Artilleries and the 108th and 150th Army Field Artillery Brigades. For the creeping barrage there were fourteen 18-pounder batteries, giving, as at Messines, about one gun to twenty yards. There were four 18-pounder batteries for distant barrage, to search hidden ground, and deal with strong points beyond the creeping barrage, while the six 4.5 howitzer batteries fired a hundred yards ahead of the latter, resting on all known strong points and machine-gun emplacements. The pace of the barrage was a hundred yards in five minutes, with a pause of thirty-five minutes in front of the Green Line. This seems as slow as could well be, but events were to prove that it was too fast in the conditions. There were three gas-shell bombardments prior to the attack, the last being on the night of the 15th, "Y/Z" night. For these there was allotted a hundred rounds per 18-pounder and fifty rounds per howitzer. One section of tanks was to take part in the attack, but there was at no time a probability of tanks reaching our front line. Zero was at 4-45 a.m.

There was very heavy shelling of the assembly trenches and the roads in rear during the night of the 15th. A small dug-out occupied by the headquarters of the 14th Rifles near Spree Farm was hit repeatedly, and it was impossible to keep alight a candle inside it. So excellent, however, was the German concrete, that it held out. Between midnight and 2-30 a.m. the four leading battalions must have suffered on an average fifty casualties apiece.

The story of the attack, alas! is not a long one. The German barrage came down swiftly, but, as it was for the most part on the assembly trenches and behind them, it had small effect upon the leading waves. But enemy machine-guns all along the front opened fire almost simultaneously with our barrage. Gallipoli, Somme, Aisne House, Hindu Cott, Schuler Farm, Border House, and Jew's Hill, were held in strength by the enemy. The concrete "pill-boxes," containing in some cases half a dozen separate compartments, seemed to be entirely unaffected by the pounding of many weeks. Moreover, strong wire entanglements running down obliquely from Gallipoli were encountered. The lanes cut by artillery fire were covered by machine-guns. The ground was a veritable quagmire. The "mopping-up" system was found to be impossible. The concrete works had to be fought for; they could not be passed by and left to "moppers up" in rear. The inevitable result was that the men quickly lost the barrage. The strength of the attacking force had become inadequate to its frontage of one thousand five hundred yards. So heavily had the battalions lost since the Division took over the line, and particularly during the last twenty-four hours in the trenches, that seventy men was about the average strength of the company. There were assuredly not two thousand infantrymen in the force which went "over the top." The foremost wave must have consisted of less than three hundred men, probably reduced to a third within half a minute. Not unfitting was the description of a sergeant who took part in the attack: "It looked more like a big raiding party than anything else."

In the circumstances, after what they had endured, with ranks so thinned, against such opposition, it may be said, without calling upon superlatives or high-flown words, that none but troops of excellent quality would have gone forward at all. The troops of the 36th Division did much more than this. On the extreme right the 9th Irish Fusiliers, attacking from the Pommern Redoubt, pressed up across Hill 35, driving the Germans before them from the gun-pits on its forward slope. The 13th Rifles on their left advanced equally well. Somme, one of the strongest forts on the front, was passed by the leading wave, but the platoon detailed to take and hold it was unable to do so, though the rifle-grenade section strove gallantly to work round and take it in flank. The adjutant, Captain Belt, made an attempt to dig in in front of the place with a handful of men, but was severely wounded and fortunate in being able to crawl back to our lines. On the right of the 36th Division, the 16th had at first made good progress, but a counter-attack drove its troops back to their original line. From six o'clock onwards men began to fall back. Colonel R. P. Maxwell, commanding the 13th, seeing what was happening, led forward his battalion headquarters to a desperate attack upon Somme. He was unsuccessful, being himself severely wounded. It will be remembered that Colonel Maxwell, who had two sons on active service, had been wounded in Martinsart on the eve of the Somme attack. He was to reappear, none the less, in France in 1918. Colonel Somerville, commanding the 9th Irish Fusiliers, had already been mortally wounded. With the failure of Colonel Maxwell's forlorn hope, it may be said that the attack on the front of the 108th Brigade collapsed, though the 9th Irish Fusiliers made an effort to cling to the top of Hill 35.

On the right of the 109th Brigade, the 14th Rifles had to cross ground far worse even than the ordinary, completely under water, in fact. In their passage they came under withering machine-gun fire from Pond Farm. Lieutenant Ledlie made a fine attempt to capture this place, surrounding it on three sides with the few men remaining to him when he reached it, and killing any Germans who showed themselves. With his numbers so greatly depleted, he waited for support before making an attempt to rush it, sending back two messages. But no supports came; the men could not face the machine-gun fire. They had already suffered greatly from the artillery barrage, which the leading waves had avoided. At eight o'clock, seeing that his position was hopeless, he withdrew his men a hundred and fifty yards, covering his retirement by Lewis-gun fire. The best work of the day was accomplished by the men of the 11th Inniskillings. They also had heaviest casualties on the right, where a mere fragment was left glued to the ground in front of the Green Line, the men crawling in to our line after dark. On the left the usual blast of fire came from Border House and Fort Hill. One officer and seven men, by doubling when they fell behind the barrage, reached the Green Line, but none could move up to their support, and they were compelled to withdraw. The men of the supporting companies rushed Fort Hill with bomb and bayonet, killing a number of Germans and taking some prisoners. This was the one appreciable gain, an advance on the extreme left of some four hundred yards. The 48th Division had not been able to accomplish even as much on the flank. From Fort Hill a rough line to the original position in Capricorn Keep was consolidated. The reserve battalions of each Brigade, the 12th Rifles on the right and the 10th Inniskillings on the left, had moved up to the Black Line, where officers busied themselves in reorganizing the men and making preparations for a possible counter-attack by the enemy. The latter may have had such intention. He was at least observed to reinforce his position strongly behind Pond Farm. On an S.O.S. rocket being sent up, our barrage fell upon his platoons moving up at this point, and scattered them with heavy loss.

General Nugent for a time contemplated a second attack with a new barrage, to take at least the Green Line. The reports of Brigadiers and Staff Officers visiting the line in the afternoon made it clear that the troops were in no fit state for any such attempt. Disorganization was still considerable; a high proportion of officers and N.C.O.'s had fallen, and the men were utterly exhausted. Moreover, neither the 108th nor the 109th Brigade could have mustered five hundred men for a new attack. General Nugent accordingly decided against this course, and instead ordered the relief of the two attacking Brigades by the 107th that night. This was carried out in circumstances of great difficulty, some platoons not quitting the front line till after five o'clock next morning. The weary remnants were moved straight back by 'bus to Winnizeele, and that night a Brigade of the 61st Division relieved the 107th Brigade in the line.

It is impossible to arrive at the exact casualties during the hours of the actual assault. Between 6 a.m. on the 16th and 9 a.m. on the 18th, however, there passed through the Divisional Dressing Stations 58 officers and 1,278 other ranks, wounded or gassed. These casualties do not include those of the attached artillery. They are very high if the depleted state of the infantry prior to the attack be taken into consideration. But they are almost insignificant if compared with the total casualties suffered in the holding of the line in the Salient, from August the 2nd to the 18th. In that period the 36th Division lost 144 officers and 3,441 other ranks killed, wounded, or missing. That is to say, it had more than two thousand casualties ere launched to the attack. Two other commanding officers, besides Colonels Somerville and Maxwell, were among the casualties. Colonel A. C. Pratt, 11th Inniskillings, had been killed at the entrance to Wieltje dug-outs early on the morning of the 16th, while Colonel Macrory, 10th Inniskillings, had been severely wounded a few days earlier. The difficulties of evacuating wounded during the action were extraordinary. Stretcher cases had to be brought by hand at least two thousand yards, and it took eight men to each stretcher. There were 433 stretcher-bearers, of whom rather more than half were R.A.M.C., the remainder being men of a Tunnelling Company and the Divisional Salvage section. Among many who displayed great bravery in the work of evacuating wounded under heavy shell-fire was the Assistant Chaplain-General of the Division, the Rev. F. J. Halahan, M.C., who by precept and personal example encouraged the stretcher-bearers to new efforts. Search parties, sent out after dark, brought in about a hundred wounded men from in front of our line. The conduct of the medical officers with the battalions, tending their wounded under the very heavy shell-fire that was maintained throughout upon the Black Line, was beyond praise. Captain Gavin, R.A.M.C., attached to the 14th Rifles, did splendid work at Rat Farm, where two other medical officers were killed. This gallant officer, who earned a bar to his Military Cross on that occasion, and had escapes little short of miraculous, was to be killed a few months later by no more serious an accident than a fall from his horse.

Among those good dumb soldiers, the transport animals, the casualties were the highest ever suffered by the Division. The pack mules, the use of which was even more necessary than at Messines, but infinitely less favoured by the terrain, were pushed forward too soon, and came under heavy machine-gun fire. Many were killed, and a far greater number had to be destroyed, though a few survived their wounds, and, like gallant veterans, bore their scars till the war was over. The loss among artillery horses was also very great.
