At half-past nine, Lieut. Niven established contact with the King's Own Yorkshire Light Infantry on the left, and with the 4th Rifle Brigade on the right. Both were suffering heavy casualties from enfilade fire; and neither, of course, could afford any assistance. At this time the bombardment recommenced with great intensity. The range of our machine-guns was taken with extreme precision. All, without exception, were buried. Those who served them behaved with the most admirable coolness and gallantry. Two were dug out, mounted and used again. One was actually disinterred three times and kept in action till a shell annihilated the whole section. Corporal Dover stuck to his gun throughout and, although wounded, continued to discharge his duties with as much coolness as if on parade. In the explosion that ended his ill-fated gun, he lost a leg and an arm, and was completely buried in the débris. Conscious or unconscious, he lay there in that condition until dusk, when he crawled out of all that was left of the obliterated trench, and moaned for help. Two of his comrades sprang from the support trench—by this time the fire trench—and succeeded in carrying in his mangled and bleeding body. But as all that remained of this brave soldier was being lowered into the trench a bullet put an end to his sufferings. No bullet could put an end to his glory.
At half-past ten the left half of the right fire trench was completely destroyed; and Lieut. Denison ordered Lieut. Clarke to withdraw the remnant of his command into the right communicating trench. He himself, with Lieut. Lane, was still holding all that was tenable of the right fire trench with a few men still available for that purpose. Lieut. Edwards had been killed. The right half of the left fire trench suffered cruelly. The trench was blown in and the machine-gun put out of action. Sergeant Scott, and the few survivors who still answered the call, made their way to the communication trench, and clung tenaciously to it, until that, too, was blown in. Lieut. Crawford, whose spirits never failed him throughout this terrible day, was severely wounded. Captain Adamson, who was handing out small arms ammunition, was hit in the shoulder, but continued to work with a single arm. Sergeant-Major Fraser, who was similarly engaged feeding the support trenches with ammunition, was killed instantly by a bullet in the head. At this time only four officers were left, Lieuts. Papineau, Vandenberg, Niven, and Clark, of whom the last two began the war in the ranks.
By 12 a.m. the supply of small arms ammunition badly needed replenishment. In this necessity the snipers of the Battalion were most assiduous in the dangerous task of carrying requests to the Brigade Headquarters and to the Reserve Battalion, which was in the rear at Belle-Waarde Lake. The work was most dangerous, for the ground which had to be covered was continually and most heavily shelled. From 12 a.m. to 1.30 p.m. the Battalion held on under the most desperate difficulties until a detachment of the 4th Rifle Brigade was sent up in reinforcement The battered defenders of the support trench recognised old friends coming to their aid in their moment of extreme trial, and gave them a loud cheer as they advanced in support. Lieut. Niven placed them on the extreme right, in order to protect the Battalion's flanks. They remained in line with the Canadian support trenches, protected by trees and hedges. They also sent a machine-gun and section, which rendered invaluable service.
At 2 p.m. Lieut. Niven went with an orderly to the Headquarters, in obedience to Brigade orders, to telephone to the General Officer Commanding the Brigade, complete details of the situation. He returned at 2.30 p.m. The orderlies who accompanied him both coming and going were hit by high explosive shells.
At 3 p.m. a detachment of the 2nd King's Shropshire Light Infantry, who were also old comrades in arms of the Princess Patricias, reached the support line with twenty boxes of small arms ammunition. These were distributed, and the party bringing them came into line as a reinforcement, occupying the left end of the support trench. At four o'clock the support trenches were inspected, and it was found that contact was no longer maintained with the regiment on the left, the gap extending for fifty yards. A few men (as many as could be spared) were placed in the gap to do the best they could. Shortly afterwards news was brought that the battalions on the left had been compelled to withdraw, after a stubborn resistance, to a line of trenches a short distance in the rear.
At this moment the Germans made their third and last attack. It was arrested by rifle fire, although some individuals penetrated into the fire trench on the right. At this point all the Princess Patricias had been killed, so that this part of the trench was actually tenantless. Those who established a footing were few in number, and they were gradually dislodged; and so the third and last attack was routed as successfully as those which had preceded it.
The afternoon dragged on, the tale of casualties constantly growing; and at ten o'clock at night, the company commanders being all dead or wounded, Lieuts. Niven and Papineau took a roll call. It disclosed a strength of 150 rifles and some stretcher-bearers.
At 11.30 at night the Battalion was relieved by the 3rd King's Royal Rifle Corps. The relieving unit helped those whom they replaced, in the last sorrowful duty of burying those of their dead who lay in the support and communicating trenches. Those who had fallen in the fire trenches needed no grave, for the obliteration of their shelter had afforded a decent burial to their bodies. Behind the damaged trenches, by the light of the German flares and amid the unceasing rattle of musketry, relievers and relieved combined in the last service which one soldier can render another. Beside the open graves, with heads uncovered, all that was left of the Regiment stood, while Lieut. Niven, holding the Colours of Princess Patricia, battered, bloody, but still intact, tightly in his hand, recalled all he could remember of the Church of England service for the dead. Long after the service was over the remnant of the Battalion stood in solemn reverie, unable it seemed to leave their comrades, until the Colonel of the 3rd King's Royal Rifle Corps gave them positive orders to retire, when, led by Lieut. Papineau, they marched back, 150 strong, to reserve trenches. On arrival they were instructed to proceed to another part of the position, where during the day they were shelled, and lost five killed and three wounded.
In the evening of the 10th the Battalion furnished a carrying party of fifty men and one officer for small arms ammunition, and delivered twenty-five boxes at Belle-Waarde Lake. One man was killed and two wounded. It furnished also a digging party of 100 men, under Lieut. Clarke, who constructed part of an additional support trench.
On May 13th the Regiment was in bivouac at the rear. The news arrived that the 4th Rifle Brigade, their old and trusty comrades in arms, was being desperately pressed. Asked to go to the relief, the Princess Patricias formed a composite Battalion with the 4th King's Royal Rifle Corps, and successfully made the last exertion which was asked of them at this period of the war.
