On June 19, the 138th Brigade, moving in conjunction with the Canadians, took and consolidated some of the trenches opposite them. Unhappily, their position did not seem to be clearly appreciated, as some of our own gas projectors fell in their new trench, almost exterminating a company of the 5th Leicesters. The sad tragedy is only alleviated by so convincing if painful a proof of the powerful nature of these weapons, and their probable effect upon the Germans.
The combined pressure of the Forty-sixth Division and of the Fourth Canadians began now to close in upon Lens. Upon June 25 the 6th South Staffords, with the brave men of the Dominion operating to the south of them, pushed the Germans off Hill 65. Upon June 28 there was a further advance of the 137th and 138th Brigades, which was much facilitated by the fact that the Canadians upon the day before had got up to the village of Leuvette upon the south. A number of casualties were caused by the German snipers after the advance, and among the killed was M. Serge Basset, the eminent French journalist, who had followed the troops up Hill 65.
A successful advance was made by the Forty-sixth Division and by the Canadians upon the evening of June 28, which carried them into the village of Avion and ended in the capture of some hundred prisoners. This operation was undertaken in conjunction with the Fifth Division near Oppy, upon the right of the Canadians. Their advance was also attended with complete success, the 95th and 15th Brigades clearing by a sudden rush more than a mile of German line and killing or taking the occupants. To the north of them both the 4th Canadians and the 46th Midlanders carried the success up the line. The advance was an extraordinary spectacle to the many who looked down upon it from the Vimy heights, for a violent thunderstorm roared with the guns, and a lashing downpour of rain beat into the faces of the Germans. They were tired troops, men of the Eleventh Reserve division, who had already been overlong in the line, and they could be seen rushing wildly to the rear before the stormers were clear of their own trenches. An unfired and brand-new machine-gun was found which had been abandoned by its demoralised crew. The flooded fields impeded the advance of the Canadians, but the resistance of the enemy had little to do with the limits of the movement.
Upon June 30 the 6th North Staffords and 7th Sherwood Foresters made a fresh advance and gained their objectives, though with some loss, especially in the case of the latter battalion. This operation was preparatory to a considerable attack upon July 1. This was carried out upon a three-brigade front, the order being 139th, 137th, 138th from the north. The 139th were in close touch with the Sixth Division, who had lent two battalions of the 71st Brigade to strengthen the assailants. The objective was from the Souchez River in the south, through Aconite and Aloof Trenches, to the junction point of the Sixth Division, north-west of Lens. The day's fighting was a long and varied one, some ground and prisoners being gained, though the full objective was not attained. The dice are still badly loaded against the attack save when the guns throw their full weight into the game. The Lincoln and Leicester Brigade in the south had the suburb of Cité du Moulin as their objective, and the 4th Lincolns next to the Canadians got well up; but the 5th Lincolns on their left were held up by wire and machine-guns. Through the gallantry of Sergeant Leadbeater one party penetrated into the suburb and made a lodgment in outlying houses, although their flank was entirely in the air. As the day wore on, the line of the 138th Brigade was driven in several times by the heavy and accurate shell-fire, but was each time reoccupied by the enduring troops, who were relieved in the morning by the 4th and 5th Leicesters, who spread their posts over a considerable area. One of these small posts, commanded by Lieutenant Bowell, was forgotten, and held on without relief, food, or water until July 5, when finding himself in danger of being surrounded this young officer effected a clever withdrawal—a performance for which he received the D.S.O.
Whilst the 138th Brigade had established itself in the fringes of Cité du Moulin, the Stafford men upon their left (137th Brigade) had captured Aconite Trench and also got among the houses. A number of the enemy were taken in the cellars, or shot down as they escaped from them, the Lewis guns doing admirable work. About one o'clock, however, a strong attack drove the Stafford men back as far as Ague Trench. The support companies at once advanced, led by Major Graham of the 5th North Staffords, who was either killed or taken during the attack, which made no progress in face of the strong masses of German infantry. The result of this failure was that the remnants of two companies of the 5th North Staffords, who had been left behind in Aconite Trench, were cut off and surrounded, all who were not killed being taken. In spite of this untoward result, the fighting on the part of the battalions engaged had been most spirited, and the conflict, after the fall of most of the officers and sergeants, had been carried on with great ardour and intelligence by the junior non-commissioned officers.
On the left, the Sherwood Forest Brigade (strengthened by the 2nd Regular battalion of their own regiment) advanced upon the Lens-Lievin Road and the network of trenches in front of them. It was all ideal ground for defence, with houses, slag-heaps, railway embankments, and everything which the Germans could desire or the British abhor. The brigade had advanced upon a three-battalion front, but as the zero hour was before dawn, and the ground was unknown to the Regular battalion upon the right, the result was loss of direction and confusion. Separated parties engaged Germans in isolated houses, and some very desperate fighting ensued. In the course of one of these minor sieges, Captain Chidlow-Roberts is said to have shot fifteen of the defenders, but occasionally it was the attackers who were overpowered by the number and valour of the enemy. The Germans tried to drive back the British line by a series of counter-attacks from the Lens-Bethune Road, but these were brought to a halt during the morning, though later in the afternoon parties of German bombers broke through the scattered line, which presented numerous gaps. The losses of the Sherwood Forester Brigade were considerable, and included 5 officers and 186 men, whose fate was never cleared up. Most of these were casualties, but some remained in the hands of the enemy. The total casualties of the division in this action came to 50 officers and about 1000 men.
This hard-fought action concluded the services of the North Midland Division in this portion of the front. It had been in the line for ten weeks, and under constant fire for the greater part of that time. The strength of the battalions had been so reduced by constant losses, that none of them could muster more than 300 men. Upon July 2 the Forty-sixth Division handed over their line to the Second Canadians and retired for a well-earned rest. Save for two very fruitful raids in the Hulluch district in the late autumn, this Division was not engaged again in 1917.
The Germans had strengthened the defence of Lens by flooding the flats to the south of the town, submerging the Cité St. Augustin, so that the Fourth Canadians on the right of the Forty-sixth Division could not push northwards, but they had advanced with steady perseverance along the south bank of the Souchez, and got forward, first to La Coulotte and then as far as the village of Avion, which was occupied by them upon June 28—a date which marked a general move forward on a front of 2000 yards from the river to Oppy. Meanwhile, the Sixth Division had also pushed in upon the north and north-west of Lens, which was closely invested. The First Canadian Division relieved the Sixth Division early in July, so that now the pressure upon Lens was carried out by three Canadian Divisions, one to the north, one to the west, and one to the south of the town. No actual attack was made until the middle of August, but for the sake of continuity of narrative we may reach forward and give some short account of the operations upon that occasion. After constant pressure, and the drifting of a good deal of gas over the huge house-covered area which faced them, the Canadians made an attack upon August 15, which brought them into the very suburbs of the town, while advancing their line both to the north and to the south of it. Two Canadian divisions, the First upon the left and the Second upon the right, made the main attack, while the Fourth Division guaranteed their southern flank. The First Division found itself in what was practically the old British line, as it was defined at the end of the Battle of Loos in September 1915, nearly two years before. This veteran division had not far to go to find its enemy, for the German trenches were not more than 120 yards away. Flooding over them after a heavy discharge of flaming oil drums, the Canadians swept with little loss up that deadly slope of Hill 70, sacred to the memory of the Scots of the Fifteenth Division and of many other brave men who found their last rest upon it. The 3rd Brigade upon the left and the 2nd upon the right topped the low hill and charged roaring down into the Cité St. Auguste beyond. There was a fierce fight at Cinnebar Trench and the other points which made up the German second line. The enemy infantry stood up stoutly to the push of bayonet, and there was some bloody work before the line was finally taken and consolidated by the Canadians. The Second Division in the meanwhile, advancing with the 5th Brigade upon the left and the 4th upon the right, had carried their charge right up to the edge of the city itself, and had established themselves among the shattered houses. As the 5th Brigade rushed forward, they encountered a body of German infantry advancing as if to an attack, so that for a few glorious minutes there was close bludgeon work in No-Man's-Land before the German formation was shattered and the stormers rushed on. A counter-attack developed about mid-day in front of the First Division, and the grey-clad troops could be clearly seen marching up in fours, breaking into artillery formation and finally deploying in line, all after the most approved British fashion—a fact which was explained later by the discovery in the dug-outs of official copies of a translation of the latest Aldershot regulations—surely a most unexpected result of the clash of the two nations, and one which is a compliment to our military instructors. The British methods of defence, however, proved upon this occasion to be more efficient than those for attack, and the Germans were shot back into the rubble-heaps behind them. The losses of the Canadians in this advance were not heavy, save in the 5th Brigade, which had in front of it a network of trenches in front of Cité St. Emile, and carried a hard task through with great valour and perseverance. From this time forward the advanced line was held, and it was only the deflection of the Canadian Corps to the north which prevented them from increasing their gains at Lens.
The seven weeks of comparative peace between the conclusion of the Battle of Messines and the beginning of those long-drawn operations which may be called the Battle of the Ridges, was broken by one tragic incident, which ended in the practical annihilation of two veteran battalions which held a record second to none in the Army. As misfortunes of this sort have been exceedingly rare in the progress of the war, it may be well to narrate this affair in greater detail than the general scale of this chronicle would justify.
