On August 14 the enemy counter-attacked with some vigour, and momentarily regained a trench near the windmill. On the 15th the line had been restored. On the 17th there was a strong attack in six successive lines upon the Forty-eighth British and the First Australian Divisions, but it had no result. On the 18th, however, the 5th and 6th Warwicks paid a return visit with great success, carrying three lines of trenches and capturing 600 prisoners. This was a very fine exploit, carried out at 5 P.M. of a summer evening.

It was about this date that a new movement began upon the British left, which extended their line of battle. Since the capture of Ovillers, a month before, the flank of the army to the left of the attack upon Pozières had been guarded by the Forty-ninth Division of Yorks Territorials, but no attack had been attempted in this quarter. On August 18 the Twenty-fifth Division relieved the Forty-ninth, and an advance upon a small scale which gradually assumed more importance was started in the direction of Thiepval, the German village fortress of sinister reputation, which lay upon the left flank on the hither side of the River Ancre. Upon this General Gough had now fixed a menacing gaze, and though his advance was gradual, it was none the less inexorable until his aim had been attained; and not only Thiepval itself but the important heights to the north and east of it which dominate the valley of the Ancre were in the hands of his persevering troops. The first obstacles in his path were a stronghold named the Leipzig Redoubt, and to the east of it a widespread farm, now spread even wider by British shells. This nest of snipers and machine-guns was known as Mouquet Farm. Upon the 19th, as part of the general attack along the line, which will be more fully dealt with elsewhere, not only was our Pozières front pushed forward past the windmill for 300 yards, but the 1st Wiltshires of the Twenty-fifth Division, operating upon the left of the Forty-eighth, which in turn was on the left of the Australians, made an important lodgment on the high ground to the south of Thiepval. The Forty-eighth Division also made some advance, the 4th Gloucesters upon the night of the 19th capturing 400 yards of trench with 200 prisoners. Their comrades of the 6th Battalion had less fortune, however, in an attack upon the German trenches on August 22, when they had two companies partially destroyed by machine-gun fire, while every officer engaged was hit, including Major Coates, who was killed. On this same day there was again an Australian advance near Pozières, whilst at the other end of the line, which was biting like acid into the German defences, the Twenty-fifth Division began to encroach upon the Leipzig salient, and were within 1000 yards of Thiepval. In this entirely successful attack a new invention, the push pipe-line, was used for the first time with some success, having the double effect of blowing up the enemy's strong point, and of forming a rudimentary communication trench in the track of its explosion. In this connection it may be stated generally that while the Germans, with their objects clear in front of them, had used before the War far greater ingenuity than the British in warlike invention, as witness the poison gas, minenwerfer and flame-throwers, their methods became stereotyped after War broke out; while the more individual Britons showed greater ingenuity and constructive ability, so that by the end of 1916 they had attained a superiority upon nearly every point. Their heavy artillery, light machine-guns, aeroplanes, bombs, trench-mortars, and gas apparatus were all of the very best; and in their tanks they were soon to take an entirely new departure in warfare. It is as difficult in our British system to fix the responsibility for good as for evil, but there is ample evidence of a great discriminating intelligence in the heart of our affairs.

The Hindenburg Trench was the immediate object of these attacks, and on August 24 a stretch of it, containing 150 occupants, was carried. A pocket of Germans was left at one end of it, who held on manfully and made a successful resistance against a company of the 8th North Lancashires, who tried to rush them. Ultimately, however, these brave men were all taken or killed.

Day by day the line crept on, and before the end of the month the 1000 yards had become 500, whilst every advance yielded some new trench with a crop of prisoners. The enemy was fully alive, however, to the great importance of the Thiepval position, which would give the British guns an opportunity of raking Beaumont Hamel and their other strongholds upon the north of the Ancre. A very strong counter-attack was made, therefore, by some battalions of the Prussian Guard on the evening of August 25, preceded by a shattering bombardment. The attack—the edge of which was blunted by the British barrage—fell mainly upon the 7th Brigade of the Twenty-fifth Division. The result was a German defeat, and the menacing line drew ever nearer to Thiepval, though an attack by the North Lancs upon the Prussian Fusilier Guards upon August 28 was not successful. On the day before, however, the Forty-eighth Division upon the right of the Twenty-fifth made a successful advance, taking a good line of trench with 100 of the redoubtable Guards. Between Thiepval and Pozières the ruins of Mouquet Farm had been taken by the West Australians and the Tasmanians, and was found to be a perfect warren of snipers, so that it was some time before it was absolutely clear. On the Pozières Ridge ground and prisoners were continually being gained, and the trenches between the Ridge and Mouquet Farm were cleared by Queensland on the right and by Tasmania on the left. It was a most spirited fight, where Australian and Prussian stood up to each other within short bomb-throw. But nothing could stand against the fire of the attack. The whole line of trench upon the right was captured. There was a dangerous gap, however, upon the Tasmanian left, and this the Tasmanians were compelled to endure for two days and nights, during which they were hard pressed by never-ending shelling and incessant German attacks. It is on record that their constant reports of their parlous state sent on to headquarters concluded always with the words: "But we will hold on." If Tasmania needs a motto, she could find no better one, for her sons lived and died up to it during those terrible hours. When at last they were relieved, their numbers were sorely reduced, but their ground was still intact. At the other side of the gap, however, the West Australians, hard pressed by an overpowering bombardment, had been pushed out from Mouquet Farm, which came back into German hands, whence it was destined soon to pass.

It was during this severe fighting that a little scene occurred which, as described by Mr. Bean, the very able Australian chronicler, must stir the blood of every Imperialist. A single officer "of middle age, erect, tough as wire, with lines on his face such as hard fighting and responsibility leave on every soldier," appeared in the Australian communication trenches, asking to see the officer-in-charge. He spoke the same tongue but with a different intonation as he explained his mission. He was the forerunner of the relieving force, and the First Division of Canada was taking over the line from Australia—a line which was destined to bring glory to each of them. Surely a great historical picture might be made in more peaceful times of this first contact of the two great nations of the future, separated by half the world from each other, and yet coming together amid blood and fire at the call of the race. An hour later, Canadian Highlanders in a long buoyant line were pushing swiftly forward to occupy the trenches which Australia had won and held. "Australians and Canadians," says Mr. Bean, "fought for thirty-six hours in those trenches inexorably mixed, working under each other's officers. Their wounded helped each other from the front. Their dead lie, and will lie, through all the centuries, hastily buried, beside the tumbled trenches and shell-holes where, fighting as mates, they died." So ended the Australian epic upon the Somme. It is to be remembered that the New Zealanders formed an entirely separate division, whose doings will presently be considered.

Whilst the Overseas troops had been fighting hard before Pozières, there had been a considerable movement upon their left to attack northwards along the Thiepval Spur. This was carried out by the Thirty-ninth Division north of the Ancre, the Forty-ninth and the Twenty-fifth upon September 3. Some ground was gained, but the losses were heavy, especially in the 75th Brigade, where the 2nd South Lancashires suffered considerably. This battalion had been in shallow trenches exposed to fire and weather for six days previous to the attack, and was greatly worn. This attack was part of the general battle of September 3, but from Mouquet Farm northwards it cannot be said to have given any adequate return for our losses.

Our narrative of the events upon the left wing of the army has now got in front of the general account, but as the operations of General Gough's force have definite objectives of their own, the story may now be continued up to September 15, after which we can leave this flank altogether for a time and concentrate upon the happenings in the centre, and especially upon the right flank where Delville Wood, Ginchy and Guillemont had presented such impediments to the advance. At or about the time, September 4, when the Canadians took over the lines of the Australians at Pozières and Mouquet Farm, the Eleventh British Division, the First English Division of the New Army, which had come back from hard service in the East, relieved the Twenty-fifth Division upon the Canadian left. For a week there was quiet upon this part of the line, for a great forward move along the whole eleven-mile front had been planned for September 15, and this was the lull before the storm. On the evening before this great assault, the Eleventh Division crept up to and carried the main German stronghold, called the Wonderwork, which lay between them and Thiepval. There was some sharp bayonet work, and the defeated garrison flying towards Thiepval ran into the barrage so that the enemy losses were heavy, while the British line crept up to within 350 yards of the village. This advance stopped for ever the flank fire by which the Germans were able to make Mouquet Farm almost untenable, and the Canadians were able to occupy it. The capture of the Wonderwork was carried out by Price's 32nd Infantry Brigade of Yorkshire troops. The most of the work and the heaviest losses fell upon the 9th West Yorks, but the 8th West Ridings and the 6th Yorks were both engaged, the latter losing their colonel, Forsyth. The total casualties came to 26 officers and 742 men.

On September 15 the Eleventh Division held the flank in front of Thiepval, but the Second and Third Canadian Divisions shared in the general advance, and pushed forward their line over the Pozières Ridge and down for 1000 yards of the slope in front, joining hands with the Fifteenth Scottish Division in Martinpuich upon the right. This fine advance crossed several German trenches, took the fortified position of the Sugar Refinery, and eventually included in its scope the village of Courcelette, which had not been included in the original scheme. All Canada, from Halifax in the east to Vancouver in the west, was represented in this victory; and it was particularly pleasing that the crowning achievement—the capture of Courcelette—was carried out largely by the 22nd Battalion of the 5th Brigade French Canadians of the Second Division. French Canada, like Ireland, has been diverted somewhat by petty internal influences from taking a wide and worthy view of the great struggle against German conquest, but it can truly be said in both cases that the fine quality of those who came did much to atone for the apathy of those who stayed. Thirteen hundred German prisoners were brought back by the Canadians. During the Courcelette operations, the Third Canadian Division was working upon the left flank of the Second as it attacked the village, protecting it from enfilade attack. The work and the losses in this useful movement fell chiefly upon the 8th Brigade.

This considerable victory was, as will afterwards be shown, typical of what had occurred along the whole line upon that great day of battle and victory. It was followed, so far as the Canadians were concerned, by a day of heavy sacrifice and imperfect success. The Third Division, still operating upon the left of the Second, endeavoured to carry the formidable Zollern Trench and Zollern Redoubt to the north of Courcelette. The 7th and 9th Brigades were in the attacking line, but the former was held up from the beginning. The latter got forward, but found itself confronted by the inevitable barbed wire, which stayed its progress. No good was done, and two gallant battalions, the 60th (Montreal) and the 52nd (New Ontario), lost 800 men between them. The operation was suspended until it could be renewed upon a larger scale and a broader front.

At this point we may suspend our account of the operations of Gough's Fifth Army, while we return to the Fourth Army upon the south, and bring the record of its work up to this same date. Afterwards, we shall return to the Fifth Army and describe the successful operations by which it cleared the Thiepval Ridge, gained command of the Ancre Valley, and finally created a situation which was directly responsible for the great German retreat in the early spring of 1917.
