The requests for assistance from guns and men from the Brigade could not be very adequately met. The Higher Command were under a double difficulty. In the first place, so heavy was the German fire on the communication trenches that it was impossible to move supports up to them in the daylight hours of that morning. In the second place, the continual breakdown in the telephone service made all information as to the precise state of affairs in the front line impossible to obtain from minute to minute. In so far, however, as messages came through they continued to confirm the original evidence which had given the Brigade a radically false view of the whole situation. The view of the Brigade was that the Germans were simply a small raiding party who had broken through a weakly-held part of the line and seized on Crater 2, and possibly Crater 3. There they were, surrounded on every side except that by which they had come in, by parties of our troops in the closest proximity to them. Capts. Gwynn and Meredith were close behind their line on the right; and it was quite wrongly believed that Major Daly and the 31st were cheek by jowl with them in Craters 4 and 5 on the left; in the centre, of course, was our main force. To start a heavy bombardment was therefore impossible, for it would have killed more Canadians than Germans; it would have been using a steam-hammer to crack a nut and cracking one's own finger instead. A bombing and rifle attack was the only way to deal with such intruders. That was the obvious argument, and it would have been correct had the premises on which it was based borne any relation to the facts. The difficulties with which General Ketchen was confronted can best be appreciated in the light of the fact that he was not definitely informed till 5 o'clock on the morning of the 6th that the two Craters—2 and 3—were lost, and that all communication with the front then ceased for two and a half hours! As it was, under the urgent pressure of Col. Snider, of the 27th, and Capt. Gwynn, artillery fire was finally opened on Crater 2.

The trench mortars in our original right-hand trenches, whose gunners were near enough to see what they were doing, were out of action. Eventually, however, some 18-pounders were turned on the enemy. Capt. Gwynn, who observed the bombardment by Fredericton Fort, was doubtful of its efficacy, but the testimony of prisoners taken during the ensuing night proves that the garrison of Crater 2 lost heavily, though not heavily enough to induce them to retire. But the main reliance was placed on a bombing and infantry attack from the north and north-east, and the 28th Battalion, which had not yet been in action, was ordered to come up from its trenches behind the centre of the position and assist in the assault.

In the meantime, the isolated parties of the 27th and the 29th were making their way back as best they could from the east to the rallying point in front of Crater 1. The stories of these successive retirements will, in the main, never be told—for too often they were cut short by death. The machine-gun teams of the 5th Brigade were also involved in the retreat. Lieut. Browne commanded the 22nd, Sergt. Naylor the 24th, Lieut. White the 25th, Lieut. Lockhart the 26th. Of all these, only one gun was brought out of action—that of Sergt. Naylor, of the 24th Battalion, who showed great presence of mind in mitigating the confusion of the mixed units in the retreat, and saved the majority of his team. The character of the force is well illustrated by the private occupations of his team. The sergeant was a storekeeper, Lance-Cpl. Rose a patternmaker, Lance-Cpl. Duley a bank teller, Private Arundel a ledger-keeper, Private Clarke a salesman, Private Burchell a private secretary.

The parties of the 25th and 26th were never seen again. They must presumably have perished, and their stories with them. One tale, however, survives—and that is the march of Lieut. Browne of the 22nd (French Canadians) and his detachment across the front and through the lines of the enemy. As has been already related, Lieut. Browne found himself on our extreme left with a Lewis gun when Capt. Gwynn went back for instructions. He fired on the Germans and saw them pass behind him to the crater. "The enemy," he says, "marched in absolute silence until I opened fire, and they extended and began to shout as they ran forward. In my opinion the enemy did not think that the front line was occupied, which would account for their advancing in close order until struck by our fire." As the enemy swung round his left, there was no outbreak of fire from the Lewis gun of the 25th Battalion—it had been buried and its crew presumably killed. Every gun and rifle save one having jammed, and the enemy being well behind the line, Lieut. Browne took his decision. "Not being able to do any effective work and believing the other crews to be out of action; also seeing the enemy closing on the left towards the craters, I decided to retire to the second line, there to unite with the garrison to make a stand." The party, which consisted of five men of the 22nd and a few others, accordingly started back north, following in the wake of the advancing Germans. There was, however, no garrison in our newly-dug second line south of the craters, for the working party had gone. Instead they encountered the barbed wire the working parties had put in front of the trench. The Germans, by now on the edge of the craters, fired on them as they were struggling through. Lance-Cpl. Lambert, Private Rattè, Private Brisebois, and a man of the 25th fell, but as they gained the other side they came across a digging party which had lost its way, and had not gone back with the others. Hastily gathering these men, Lieut. Browne charged for the spot where they had been fired on. Not a man had a rifle which would work, but they rushed in like the paladins of romance on the armed Germans who were in the trench. These they killed in hand-to-hand conflict with the butts of their rifles. Alter this notable feat of arms the party got into the new second line trench and proceeded along it towards Fredericton Fort. As they came running down the trench, the Germans came out of the crater against them, but Lieut. Browne's detachment managed to elude the enemy. Picking up some of the 29th, and the gun crew of the 24th on the way, Lieut. Browne succeeded in reaching Fredericton Fort, where he found Capts. Gwynn and Meredith. Of his original section only two remained alive. None the less, each new group had rallied round this officer, and were "ready for a fight at any time." Such a story of valour and discretion exceeds all that fiction has ever imagined. April 6th, 7 A.M. At 7 a.m. on the morning of the 6th, all telephone communication with the officers at Fredericton Fort ceased. The last message which came through to Capt. Gwynn (as appeared subsequently) from the Canadian communication trench was a simple and tragic one: "We are retiring." Isolated by now on both right and left, and with the enemy in front and rear, Capt. Gwynn still held firm until he was reasonably certain that the last party from the abandoned line had come in. Finally, some two hours afterwards, no orders having been received, as indeed they could not be, he decided to retire. His men were falling fast in an impossible position and no alternative was open to him.

Fortunately, a message asking for the support of the machine-guns in our original trenches on the right had got through, and under cover of their fire and the shelling of the Crater 2 by our 18-pounders, Capt. Gwynn conducted a successful retirement to the old lines. In this emergency the 27th and the 29th were ably led, and seconded their officers' efforts to the last. The news of this final movement on the right did not reach the Brigade until some time later in the day.

With this retirement the first phase of the battle comes to an end. The new line has been indubitably lost with the exception of a few outpost positions like the minor craters, and the remainder of the prolonged struggle is devoted to the attempt to reoccupy by a series of counter-attacks ground which has been abandoned, and to oust the enemy from the craters. It will be well to defer to a later stage a full consideration of all the circumstances which prevented a successful issue, but something may be said with advantage on the fighting from the night of April 3rd, when the Canadian 2nd Division took over, to the morning of the 6th, when the German advance succeeded. It is inevitable that the mere event should leave behind it a certain trace of bitterness. To lose trenches, however indefensible, can never be pleasant. Failure must differ from success whatever the real merits of the case may be. And it is part of the tragedy of modern warfare that the real conditions which make such a retirement unavoidable can never be understood to the full by those who have not gone through the experience of a general action in trench warfare. No word painting, however vivid, can make the picture actual to minds which have mercifully been preserved from the experience and to eyes which have never seen a modern battlefield. The shock of squadrons, the bayonet charge, or the exchange of point-blank volleys between opposing battalions has become familiar to us in history-books, and the artist can draw them to the life. It is easy to grasp the recoil of a column down the hill-side under the furious impetus of an overwhelming assault. But to be killed in sections by high explosives and machine-guns in a trench which is rapidly ceasing to exist, so that the agony is prolonged for hours, is an ordeal more difficult to grasp. The mere reiteration of its horrors dulls the sense of the reader as the actuality strains the nerves of the soldier. Every sentence would have to end with the word "shell." The knowledge that to stay is useless because no attack will be made while anyone remains alive; that to bring up supports is impossible under the barrage, and that anyone who came would merely share your fate; the impossibility of keeping pace with the destruction of your only cover; the biting fire from rear, front and flank; the impotence of gripping a useless rifle—these things are indeed worse than the bitterness of death! The men of the 6th Brigade were right in retiring as soon as the line was broken and had become indefensible, and when no supports could be brought up to their assistance. But, apart from the unavoidable necessities of the case, the 2nd Division suffered from ill-luck. In all military operations luck is of primary importance, because even the best planned and most carefully executed schemes are met by such unexpected changes and conditions that they go to ruin through the Unforeseen. Every commander must expect a reasonable share of the favours of fortune. That share was in this action conspicuously lacking. The mistake about the identity of the Craters 4 and 5 was the beginning of all the trouble. Had the 31st Battalion occupied these instead of Craters 6 and 7, when they were blown out of Campbelltown Corner, they might have checked the whole enemy advance and made the Germans in Craters 2 and 3 what they were for long believed to be by the Higher Command, an isolated group partly surrounded by the Canadians. The initial mistake was the precipitate action and belief of the 31st Battalion, due to the fact that no one knew the ground as it had been transformed by mine and shell fire. But the results of the blunder were cumulative.

The counter-attack on the night of the 6th-7th—dealt with in the next chapter—by the 27th and 31st Battalions confirmed and exaggerated the error by failing to get to the real craters, although the men of these battalions were firmly convinced that they had done so. They found men holding what they thought to be Crater 5, and naturally believed them. The result was to immobilise our artillery during the crucial phase of the action and for days afterwards. Had we known that the whole crater line in the centre was held by the Germans, we could almost certainly have blown them out of it. As it was our gunners were crippled by the fear of destroying the positions of their own infantry. Such a mistake is no doubt "the luck of war," and in the ordinary course of events it would soon have been rectified by the photographic pictures taken by our aeroplanes. But here came the crowning blow of a malignant fortune. All through the first fortnight of the action a great gale blew. It not only hindered our actions on the surface of the earth, but it absolutely stopped them in the air. No aeroplane could go up in it, and the vital facts of the position were hidden from the commanders until the morning of April 16th.

Confronted by all these adverse circumstances, the companies of the 27th, 29th and the 31st did all that mortal men could do. In the face of heavy casualties, and holding positions under intolerable artillery fire, they stood their ground firmly so long as defence was possible, and retired, in rallying groups when to hold on was merely suicide they did not command success; they deserved it.

[[1]] The whole of this line from the Canadian communication trench to Campbelltown Corner consisted of German communication, or second and third line, trenches, which had been battered in turn by the guns of both sides.

[[2]] A traverse is the projection of earth back into the firing trench which divides it into sections or firing bays. Its object is to give cover against flank fire, so that if an enemy enfilades you he cannot sweep right down the length of the trench. A trench without traverses is therefore very dangerous.
