But they could never have conveyed to you the overwhelming, unimaginable truth—that this little sketch of a few yards of trench must be repeated over miles and miles of front, with the same dusty figures at the parapet, the same headless and armless dead, the same suffering wounded, the same rain of shells, if one would bring home an impression of the second battle of Ypres.

One reads that the endurance of the men was wonderful. But one does not understand. I saw the men who came alive out of that hell in the salient, and they were as men transfigured. Not that they were shaken, depressed, or, on the other hand, exultant. They were just uncannily quiet, sitting about in the sunshine, rather limp, like men recovering from supreme fatigue. Talking to them, one felt somehow that their characters had changed; that they would never look on life again as they had done in the past; that they had acquired a new seriousness of mind, as though their glimpse into the dark valley had sobered them. And they all had a puckered, strained look about the eyes, the look one sometimes sees in men who have spent their lives in the open under a tropical sun. At first these symptoms used to puzzle me. They did after the battle of Ypres. Afterwards I found out that they were the badge of the modern battle, and that, with a week of rest and change of scene, they pass away.

The ruthless bombardment with which the Germans occupied the last days of April were the preliminary to a fresh onslaught on the troops holding the northern part of the salient. In the meantime, the French counter-attacks having made no progress, Sir John French, in accordance with his arrangement with General Foch, decided that he could not afford to hold on any longer to our present exposed position. He therefore gave orders to Sir Herbert Plumer, who was directing the operations of the army engaged in defending the salient, to fall back upon a new line which had already been prepared in anticipation of this emergency. The effect of the withdrawal was to diminish considerably the arc of the salient, the whole of the centre falling back to a line starting east of Wieltje on the Ypres-Fortuin Road, running across the Ypres-Frezemberg Road south of Frezemberg, cutting through the Ypres-Thourout railway-line, and then the Ypres-Menin Road east of Hooge.

Before the withdrawal could be begun, however—the day was May 2—the Germans, having obtained fresh supplies of chlorine gas in tank waggons from Belgium, launched a gas attack from St. Julien against the 12th and 10th Brigades, which, with the 11th Brigade, were holding the line round this village and down to Fortuin. By this time our men were provided with respirators of a sort, as the result of the appeal made by the army, and magnificently responded to by the women of Britain. Unfortunately the respirators were of rather a rudimentary pattern—they have since been replaced by an entirely efficacious model—and they did not serve wholly to protect our men from the poisonous fumes. Notably the 2nd Lancashire Fusiliers and the Essex Regiment got the full blast of the noxious vapours. Despite many acts of individual gallantry shown by officers and men of the Lancashire Fusiliers, they could not hold the trench, and the line was forced back.

It was here that Jack Lynn won the Victoria Cross, conferred posthumously, for this brave fellow did not survive his gallant action. He was in the machine-gun pit when the deadly cloud approached, but without waiting to adjust his respirator he kept his machine-gun playing on the dense billows of greenish-yellow smoke. The cloud caught him and eddied about him, but his fingers never left the button of the gun, which barked on incessantly as the dimly descried forms of the Germans appeared creeping over the open. Choking and gasping as he was, Lynn hoisted his machine-gun on the parapet, and there, amid a storm of bullets, a lonely figure in a trench full of dead and dying, he kept his gun going on the enemy till he collapsed. The German infantry could not face the storm of fire, and returned to their trenches.

Lynn had collapsed by his gun when his comrades found him. They took him to a dug-out, half-conscious, but even then, when a machine-gun started barking near by, that gallant spirit struggled to regain his feet to get back to “his gun.” He died there in the sunset, with the din of battle ringing in his ears, only a Liverpool van-boy, “jes’ a little bet of a chaap,” one of his mates told me afterwards, but a man with a mighty soul.

The 2nd Seaforths were also badly gassed, but with true Scottish tenacity they stuck to their trenches until relief came. It was not long delayed. The Cavalry Division in support sent up the 4th Hussars, who executed a splendid charge side by side with the 7th Argyll and Sutherland Highlanders (Territorials), who had already done so well at St. Julien. Hussars and Highlanders went forward, head down, through the gas fumes straight into the Germans, ambling to what they imagined was an easy triumph. There was some swift and silent slaying, and the Germans went back the way they had come with sorely diminished numbers. Said General Hull to me afterwards with a chuckle: “We got the Boches on the hop that time.”

Fighting went on all that day and the next. It was essential to conceal from the enemy our withdrawal, which was timed to begin after dark. The continual counter-attacks delivered by these brigades effectually contrived to mask our intentions from him. As a result we were able to withdraw the whole centre of our line and take up the new position we had prepared almost without a casualty, and without the Germans being a penny the wiser. In fact, they continued to pour a devastating fire into our empty trenches until 3.30 on the afternoon following the withdrawal.

The retirement began at 10 p.m. on the night of May 3. The arrangement was that, first, part of the infantry should withdraw, followed after an interval by a portion of the remainder, each battalion leaving behind twenty picked shots to man the parapet and pick off any German that showed himself. It was a most delicate undertaking. The least mistake would have betrayed our move to the Germans. At some places—for instance, at Broodseinde—the trenches were only ten yards apart. Talking and smoking were forbidden. Our men just slipped away in silence through the darkness, the officers hoping in their hearts that they might get away undiscovered.

With a muttered “Good-night and good luck” to the lonely figures left at the parapet, looking out over the dreary expanse between the trenches, where spasmodic flares vouchsafed a glimpse from time to time of gaping shell-holes, a wild tangle of barbed wire and dead in uniforms brown and green, the first batch of troops silently filed out of the trenches. What a crew they were, with an eight-days’ beard, unwashed and unkempt, their faces and uniforms smeared with clay! With that peculiar hitch that Tommy gives to his pack behind when he starts off, they trudged out into the black night, their backs turned to the enemy.
