At the appointed hour the mines were exploded with deadly effect, and in the pitch darkness of a cloudy rainy morning the two battalions sprang resolutely forward upon their dangerous venture. The trenches on each flank were carried, and 5 officers with 193 men of the 18th Reserve Jaeger fell into our hands. As usual, however, it was the retention of the captured position which was the more difficult and costly part of the operation. The Northumberlands had won their way round on the right, but the Fusiliers had been partially held up on the left, so that the position was in some ways difficult and irregular. The guns of the Third Division threw forward so fine a barrage that no German counter-attack could get forward, but all day their fire was very heavy and deadly upon the captured trenches, and also upon the two battalions in support. On the night of the 27th the 9th Brigade was drawn out and the 8th took over the new line, all access to it being impossible save in the darkness, as no communication trenches existed. The situation was complicated by the fact that although the British troops had on the right won their way to the rear of the craters, one of these still contained a German detachment, who held on in a most heroic fashion and could not be dislodged. On March 30 the situation was still unchanged, and the 76th Brigade was put in to relieve the 8th. The 1st Gordons were now in the line, very wet and weary, but declaring that they would hold the ground at all costs. It was clear that the British line must be extended and that the gallant Germans in the crater must be overwhelmed. For this purpose, upon the night of April 2, the 8th Royal Lancasters swept across the whole debatable ground, with the result that 4 officers and 80 men surrendered at daylight to the Brigade-Major and a few men who summoned them from the lip of the crater. The Divisional General had himself gone forward to see that the captured ground was made good. “We saw our Divisional General mid-thigh in water and splashing down the trenches,” says an observer. “I can tell you it put heart into our weary men.” So ended the arduous labours of the Third Division, who upon April 4 handed over the ground to the 2nd Canadians. The episode of the St. Eloi craters was, however, far from being at an end. The position was looked upon as of great importance by the Germans, apart from the artillery observation, for their whole aim was the contraction, as that of the British was the expansion, of the space contained in the Ypres salient. “Elbow room! More elbow room!” was the hearts’ cry of Plumer’s Second Army. But the enemy grudged every yard, and with great tenacity began a series of counter-attacks which lasted with varying fortunes for several weeks.
Hardly had the Third Division filed out of the trenches when the German bombers were buzzing and stinging all down the new line, and there were evident signs of an impending counter-attack. Upon April 6 it broke with great violence, beginning with a blasting storm of shells followed by a rush of infantry in that darkest hour which precedes the dawn. It was a very terrible ordeal for troops which had up to then seen no severe service, and for the moment they were overborne. The attack chanced to come at the very moment when the 27th Winnipeg Regiment was being relieved by the 29th Vancouvers, which increased the losses and the confusion. The craters were taken by the German stormers with 180 prisoners, but the trench line was still held. The 31st Alberta Battalion upon the left of the position was involved in the fight and drove back several assaults, while a small French Canadian machine-gun detachment from the 22nd Regiment distinguished itself by an heroic resistance in which it was almost destroyed. About noon the bombardment was so terrific that the front trench was temporarily abandoned, the handful of survivors falling back upon the supports. The 31st upon the left were still able to maintain themselves, however, and after dusk they were able to reoccupy three out of the five craters in front of the line. From this time onwards the battle resolved itself into a desperate struggle between the opposing craters. During the whole of April 7 it was carried on with heavy losses to both parties. On one occasion a platoon of 40 Germans in close formation were shot down to a man as they rushed forward in a gallant forlorn hope. For three days the struggle went on, at the end of which time four of the craters were still held by the Canadians. Two medical men particularly distinguished themselves by their constant passage across the open space which divided the craters from the trench. The consolidation of the difficult position was admirably carried out by the C.R.E. of the Second Canadian Division.
The Canadians were left in comparative peace for ten days, but on April 19 there was a renewed burst of activity. Upon this day the Germans bombarded heavily, and then attacked with their infantry at four different points of the Ypres salient. At two they were entirely repulsed. On the Ypres-Langemarck road on the extreme north of the British position they remained in possession of about a hundred yards of trench. Finally, in the crater region they won back two, including the more important one which was on the Mound. Night after night there were bombing attacks in this region, by which the Germans endeavoured to enlarge their gains. New Brunswick and Nova Scotia were now opposed to them and showed the same determination as the men of the West. The sector held by the veteran First Canadian Division was also attacked, the 13th Battalion having 100 casualties and the Canadian Scots 50. Altogether this fighting had been so incessant and severe, although as a rule confined to a very small front, that on an average 1000 casualties a week were recorded in the corps. The fighting was carried on frequently in’ heavy rain, and the disputed craters became deep pools of mud in which men fought waist deep, and where it was impossible to keep rifle or machine-gun from being fouled and clogged. Several of the smaller craters were found to be untenable by either side, and were abandoned to the corpses which lay in the mire.
The Germans did not long remain in possession of the trench which they had captured upon the 19th in the Langemarck direction. Though it was almost unapproachable on account of the deep mud, a storming column of the 1st Shropshires waded out to it in the dark up to their waists in slush, and turned the enemy out with the point of the bayonet. Upon April the 21st the line was completely re-established, though a sapper is reported to have declared that it was impossible to consolidate porridge. In this brilliant affair the Shropshires lost a number of officers and men, including their gallant Colonel, Luard, and Lieutenant Johnstone, who was shot by a sniper while boldly directing the consolidation from outside the parapet without cover of any kind. The whole incident was an extraordinarily fine feat of arms which could only have been carried out by a highly disciplined and determined body of men. The mud was so deep that men were engulfed and suffocated, and the main body had to throw themselves down and distribute their weight to prevent being sucked down into the quagmire. The rifles were so covered and clogged that all shooting was out of the question, and only bombs and bayonets were available for the assault. The old 53rd never did a better day’s work.
During the whole winter the Loos salient had been simmering, as it had never ceased to do since the first tremendous convulsion which had established it. In the early part of the year it was held by cavalry brigades, taking turns in succession, and during this time there was a deceptive quiet, which was due to the fact that the Germans were busy in running a number of mines under the position. At the end of February the Twelfth Division took over the north of the section, and for ten weeks they found themselves engaged in a struggle which can only be described as hellish. How constant and severe it was may be gauged from the fact that without any real action they lost 4000 men during that period. As soon as they understood the state of affairs, which was only conveyed to them by several devastating explosions, they began to run their own mines and to raid those of their enemy. It was a nightmare conflict, half above ground, half below, and sometimes both simultaneously, so that men may be said to have fought in layers. The upshot of the matter, after ten weeks of fighting, was that the British positions were held at all points, though reduced to an extraordinary medley of craters and fissures, which some observer has compared to a landscape in the moon. The First Division shared with the Twelfth the winter honours of the dangerous Loos salient.

br /> On April 27 a considerable surface attack developed on this part of the line, now held by the Sixteenth Irish Division. Early upon that day the Germans, taking advantage of the wind, which was now becoming almost as important in a land as it had once been in a sea battle, loosed a cloud of poison upon the trenches just south of Hulluch and followed it up by a rush of infantry which got possession of part of the front and support Hues in the old region of the chalk-pit wood. The 49th Brigade was in the trenches. This Brigade consisted of the 7th and 8th Inniskillings, with the 7th and 8th Royal Irish. It was upon the first two battalions that the cloud of gas descended, which seems to have been of a particularly deadly brew, since it poisoned horses upon the roads far to the rear. Many of the men were stupefied and few were in a condition for resistance when the enemy rushed to the trenches. Two battalions of Dublin Fusiliers, however, from the 48th Brigade were in the adjoining trenches and were not affected by the poison. These, together with the 8th Inniskillings, who were in the rear of the 7th, attacked the captured trench and speedily won it back. This was the more easy as there had been a sudden shift of wind which had blown the vile stuff back into the faces of the German infantry. A Bavarian letter taken some days later complained bitterly of their losses, which were stated to have reached 1300 from poison alone. The casualties of the Irish Division were about 1500, nearly all from gas, or shell-fire. Coming as it did at the moment when the tragic and futile rebellion in Dublin had seemed to place the imagined interests of Ireland in front of those of European civilisation, this success was most happily timed. The brunt of the fighting was borne equally by troops from the north and from the south of Ireland — a happy omen, we will hope, for the future.
Amongst the other local engagements which broke the monotony of trench life may be mentioned one upon May 11 near the Hohenzollern Redoubt where the Germans held for a short time a British trench, taking 127 of the occupants prisoners. More serious was the fighting upon the Vimy Ridge south of Souchez on May 15. About 7:30 on the evening of that day the British exploded a series of mines which, either by accident or design, were short of the German trenches. The sector was occupied by the Twenty-fifth Division, and the infantry attack was entrusted to the 11th Lancashire Fusiliers and the 9th North Lancashires, both of the 74th Brigade. They rushed forward with great dash and occupied the newly-formed craters, where they established themselves firmly, joining them up with each other and cutting communications backwards so as to make a new observation trench.
The Twenty-fifth Division lay at this time with the Forty-seventh London Division as its northern neighbour, the one forming the left-hand unit of the Third Army, and the other the extreme right of the First. Upon the 19th the Londoners took over the new position from the 74th, and found it to be an evil inheritance, for upon May 21, when they were in the very act of relieving the 7th and 75th Brigades, which formed the front of the Twenty-fifth Division, they were driven in by a terrific bombardment and assault from the German lines. On the front of a brigade the Germans captured not only the new ground won but our own front line and part of our supporting line. Old soldiers declared that the fire upon this occasion was among the most concentrated and deadly of the whole War. With the new weapons artillery is not needed at such short range, for with aerial torpedoes the same effect can be produced as with guns of a great calibre.
In the early morning of April 30, there was a strong attack by the Germans at Wulverghem, which was the village to the west of Messines, to which our line had been shifted after the attack of November 2, 1914. There is no doubt that all this bustling upon the part of the Germans was partly for the purpose of holding us to our ground while they dealt with the French at Verdun, and partly to provoke a premature offensive, since they well knew that some great movement was in contemplation. As a matter of fact, all the attacks, including the final severe one upon the Canadian lines, were dealt with by local defenders and had no strategic effect at all. In the case of the Wulverghem attack it was preceded by an emission of gas of such intensity that it produced much sickness as far off as Bailleul, at least six miles to the west. Horses in the distant horse lines fell senseless under the noxious vapour. It came on with such rapidity that about a hundred men of the Twenty-fourth Division were overcome before they could get on their helmets. The rest were armed against it, and repelled the subsequent infantry attacks carried out by numerous small bodies of exploring infantry, without any difficulty. The whole casualties of the Fifth Corps, whose front was attacked, amounted to 400, half by gas and half by the shells.
In May, General Alderson, who had commanded the Canadians with such success from the beginning, took over new duties and gave place to General Sir Julian Byng, the gallant commander of the Third Cavalry Division.
Upon June 2 there began an action upon the Canadian front at Ypres which led to severe fighting extending over several weeks, and put a very heavy strain upon a corps the First Division of which had done magnificent work during more than a year, whilst the other two divisions had only just eased up after the fighting of the craters. Knowing well that the Allies were about to attack, the Germans were exceedingly anxious to gain some success which would compel them to disarrange their plans and to suspend that concentration of troops and guns which must precede any great effort. In searching for such a success it was natural that they should revert to the Ypres salient, which had always been the weakest portion of the line — so weak, indeed, that when it is seen outlined by the star shells at night, it seems to the spectator to be almost untenable, since the curve of the German line was such that it could command the rear of all the British trenches. It was a region of ruined cottages, shallow trenches commanded by the enemy’s guns, and shell-swept woods so shattered and scarred that they no longer furnished any cover. These woods, Zouave Wood, Sanctuary Wood, and others lie some hundred yards behind the front trenches and form a rallying-point for those who retire, and a place of assembly for those who advance.
The Canadian front was from four to five miles long, following the line of the trenches. The extreme left lay upon the ruined village of Hooge. This part of the line was held by the Royal Canadian Regiment. For a mile to their right, in front of Zouave and Sanctuary Woods, the Princess Patricia’s held the line over low-lying ground. In immediate support was the 49th Regiment. These all belonged to the 7th Canadian Brigade. This formed the left or northern sector of the position.
In the centre was a low hill called Mount Sorel, in which the front trenches were located. Immediately in its rear is another elevation, somewhat higher, and used as an observing station. This was Observatory Hill. A wood, Armagh Wood, covered the slope of this hill. There is about two hundred yards of valley between Mount Sorel and Observatory Hill, with a small stream running down it. This section of the line was essential for the British, since in the hands of the enemy it would command all the rest. It was garrisoned by the 8th Brigade, consisting of Canadian Mounted Rifles.
The right of the Canadian line, including St. Eloi upon the extreme limit of their sector, was held by troops of the Second Canadian Division. This part of the line was not involved in the coming attack. It broke upon the centre and the left, the Mount Sorel and the Hooge positions.
The whole operation was very much more important than was appreciated by the British public at the time, and formed a notable example of anticipatory tactics upon the part of the German General Staff. Just as they had delayed the advance upon the west by their furious assault upon Verdun on the east, so they now calculated that by a fierce attack upon the north of the British line they might disperse the gathering storm which was visibly banking up in the Somme Valley. It was a bold move, boldly carried out, and within appreciable distance of success.
Their first care was to collect and concentrate a great number of guns and mine-throwers on the sector to be attacked. This concentration occurred at the very moment when our own heavy artillery was in a transition stage, some of it going south to the Somme. Hardly a gun had sounded all mor
ning. Then in an instant with a crash and a roar several mines were sprung under the trenches, and a terrific avalanche of shells came smashing down among the astounded men. It is doubtful if a more hellish storm of projectiles of every sort had ever up to that time been concentrated upon so limited a front. There was death from the mines below, death from the shells above, chaos and destruction all around. The men were dazed and the trenches both in front and those of communication were torn to pieces and left as heaps of rubble.
One great mine destroyed the loop of line held by the Princess Patricia’s and buried a company in the ruins. A second exploded at Mount Sorel and did great damage. At the first outburst Generals Mercer and Williams had been hurried into a small tunnel out of the front line, but the mine explosion obliterated the mouth of the tunnel and they were only extricated with difficulty. General Mercer was last seen encouraging the men, but he had disappeared after the action and his fate was unknown to friend or foe until ten days later his body was found with both legs broken in one of the side trenches. He died as he had lived, a very gallant soldier. For four hours the men cowered down in what was left of the trenches, awaiting the inevitable infantry attack which would come from the German lines fifty yards away. When at last it came it met with little resistance, for there were few to resist. Those few were beaten down by the rush of the Würtembergers who formed the attacking division. They carried the British line for a length of nearly a mile, from Mount Sorel to the south of Hooge, and they captured about 500 men, a large proportion of whom were wounded. General Williams, Colonel Usher, and twelve other officers were taken.
