It was the first great effort ever made by the British to pierce the German line since it had been established after the open field battles of the Marne and the Aisne. The British troops had faced the German lines for months, and while the fundamental principles of the German defences were fairly well understood, their real strength was very much underrated.

Things went badly from the beginning of the action. The artillery "preparation" represented quite the most formidable bombardment the British had so far made, but even so, it was ineffective along certain sections of the line. After the way had been paved by shrapnel and high explosive, the British infantry moved forward in a splendid offensive to secure what everyone believed would be a decisive victory; and trained observers of the battle were under the impression that the gallant British infantry had won their end. This is an impression, too, which was shared by some of the men for a time.

For many months the British had been almost entirely on the defensive, and over and over again been called on to repulse heavy, massed German attacks. The casualties sustained in repulsing these attacks first revealed our shortage of machine-guns. What they lacked in machine-guns, however, the British troops made up for in a deadly accuracy of rifle fire, which was at once the terror and the admiration of the Germans. The British had thus come to an exaggerated idea of the efficacy of rifle fire, and a consequent over-estimate of the importance of the German first line trenches. Over these they swarmed, and the word went forth that the day was won.

It was only when the British troops had occupied the enemy's first and second line trenches, they discovered that, in actual fact, they had not done more than drive in the outposts of an army. Close at hand, the Germans' third line loomed up like a succession of closely interlocked citadels. Nay, more, those citadels were so constructed that the trenches from which our men had ousted the enemy with so much heroism and loss were deathtraps for the new tenants. The circumstances were such that to retire meant acknowledgment of failure, and to hang on, a grisly slaughter.

Even so, there were features of the situation which made for hope. There were positions to be won which would very seriously jeopardise the whole German scheme of defence; but, at the critical moment of the battle, the advanced troops seem to have passed beyond the control of the various commanders in the rear on account of the misty weather.

The real tragedy, however, was the non-arrival of the supports at a point and at a time when the appearance of reserves might have made all the difference to the fortunes of the day. The enemy was still bewildered and demoralised, and, but for the delay, might have been completely routed. Unfortunately, the British front was in great need of straightening out. The 23rd Brigade continued to hang up the 8th Division, while the 25th Brigade was fighting along a portion of the front where it was not supposed to be at all. Units had to be disentangled and the whole line straightened before further advance could be made.

The fatal result was a delay which, Sir John French says, would never have occurred had the "clearly expressed orders of the General Officer commanding the 1st Army been more carefully observed."

Sir Douglas Haig himself hurried up to set things right, but it was then too late to retrieve the failure which had been occasioned by delay. The attack was thoroughly exhausted, its sting was gone, and the enemy had pulled himself together. Night was falling, and there was nothing to be done but "dig in" beneath the ridge above Lille, the capture of which would have altered the whole story of the campaign on the Western front.

As I have said, the Canadian infantry took no part in the battle, though the troops waited impatiently and expectantly for the order to advance, but the activity of the Canadian artillery was considerable and important. The Canadian guns took their full share in the "preparation" for the subsequent British infantry attack, and the observation work of our gunners was good and continuous.

After Neuve Chapelle, quiet reigned along the Canadian trenches, though the battle raged to the north of us at St. Eloi, and the Princess Patricia's Battalion was involved. Early in the last days of March our troops were withdrawn and retired to rest camps.
