CHAPTER XV.
THE LAST BATTLE.
By the 25th of September the German armies were back on the great line devised by Hindenburg in the autumn of 1916. The one chance left to them was to hold out there during the winter, in the hope that they might be able to bargain with the Allies. If the Allies attacked, there were two sections which Ludendorff viewed with anxiety. One was his left wing on the Meuse, where, if the Allies broke through, the Hindenburg Line would be turned on its flank. The other was the German centre from Douai to St. Quentin, the main Hindenburg Line, which was not only the fortress where he hoped to pass the winter, but the one protection of the great railway from Lille by Valenciennes to Mezières, on which his whole position depended. He therefore laboured to keep his left and centre as strong as possible; for, in spite of his experience in August and September, he could not conceive the possibility of an assault on every section.
For Foch this was to be the crowning battle of the war. If he could break through the German centre, and at the same time turn the German left, defeat would stare the enemy in the face, and there would be victory long before Christmas. If the Americans on the Meuse succeeded, they would make retreat imperative; but if Haig in the centre succeeded, he would make retreat impossible, and disaster must follow. The British were assigned the most difficult part. They had to attack in the area where the enemy defences were most highly organized and his forces strongest. If the Hindenburg Line held, the German courage might yet recover, and a new era of resistance begin. Haig's armies had already borne the heaviest share of the summer fighting, and every division had been sorely tried. Yet the attempt must be made, for it was the essential part of the whole strategy, and the measure of difficulty was the measure of the honour in which Foch held the fighting qualities of his British allies.
In deciding to make the attack, and to break the Hindenburg Line at one blow, Sir Douglas Haig stood alone. So difficult seemed the operation that the British Government were in the gravest doubts, and left the burden of responsibility upon the Commander-in-Chief. Even the French generals hesitated. The movement was undertaken on Sir Douglas Haig's initiative; he bore the whole burden of it; and therefore to him belongs the main credit of what was destined to be one of the decisive actions of the war.
Foch began on his right flank, and on 26th September the American army attacked on the Meuse. Next day, the 27th, Haig struck towards Cambrai. The two main defences of the Hindenburg Line were the Canal du Nord, and, behind it, the Scheldt Canal, the latter forming the outwork of the system. The principal German trenches were on the east bank; but on the west bank lay advanced posts, skilfully placed. In one section the canal passed through a tunnel 6,000 yards long, connected by shafts with the trenches above. In another part it lay in a deep cutting, the sides of which were honeycombed with dug-outs. The fortified zone was from 5 to 7 miles wide, and culminated on the east in what was known as the Beaurevoir Line, strongly wired double-trench lines of the same type as those on the western side.
On the 27th the Third Army under Byng, and the First Army under Horne, attacked on the left, crossed the Canal du Nord, and by the evening had reached the edge of the Scheldt Canal. Next day that canal had been partially crossed, and Cambrai was menaced from two sides. These events roused acute apprehension in the mind of the German Staff. The crossing of the Canal du Nord by Tanks on the backs of Tanks, and the passing of the Scheldt Canal at its northern end, had shaken their confidence in the outer Hindenburg defences. Next day, the 29th, came Haig's crowning blow. He struck at the strongest part, and it crumbled before him.
The attack was made by Rawlinson's Fourth Army. For two days his guns had not been silent; the enemy's garrisons were forced into tunnels and deep dug-outs, and the transport of food and ammunition was made all but impossible. The Germans were, therefore, in a state of confusion and fatigue when Haig attacked at 10 minutes to 6 on the morning of Sunday, the 29th.
This action was one of the greatest of the campaign, whether we regard the difficulties to be faced or the strategic value of the gains. Ludendorff was fighting for his last hope, and he had warned his men accordingly. One captured order reminded his troops that "Our present position is our winter position." Another ran: "There can be no question of going back a single step further. We must show the British, French, and Americans that any further attacks on the Hindenburg Line will be utterly broken, and that that Line is an impregnable rampart, with the result that the Entente Powers will condescend to consider the terms of peace which it is absolutely necessary for us to have before we can end the war." Germany was already busy with peace proposals, and she had nothing to bargain with except these defences in the West.
The key of the position was the angle of the Scheldt Canal where it bent east, with the village of Bellenglise in its bend, for if the canal were forced there the defences on either side would be turned. The work was entrusted to the 46th Division of North Midland Territorials, which had a long and brilliant record in the war. Theirs was an amazing performance. The canal before them was some 50 to 60 feet wide, the water in some parts being as much as 10 feet deep. and in others a mere trickle. It was a morning of thick fog when behind the tornado of the barrage the Midlanders, carrying life-belts and mats and rafts, advanced to the attack. Since parts of the canal were impassable, the crossing had to be made on a narrow front. Swimming or wading, and in some cases using foot-bridges which the enemy had left undestroyed, they passed the canal west and north of Bellenglise, swarmed up the farther bank, and took the German trenches beyond. Then, fanning out, they attacked in rear the positions to the south, capturing many batteries still in action. That day this one Division took over 4,000 prisoners and 70 guns.
It was the same everywhere else on the British front. The main Hindenburg defences had been breached, and all next day the Fourth Army pressed through the gap. The greatest battle of the war was now approaching its climax, and the whole 250 miles of front, from the Meuse to the sea, were ablaze. Ludendorff could not have withdrawn even if he had wished it. By 7th October Haig had broken through all the front Hindenburg Line, and was pressing upon the last defences. The time was therefore ripe for a great movement on the broadest possible front, which would destroy the whole zone. For, in the words of the official dispatch, "Nothing but the natural obstacles of a wooded and well-watered country lay between our armies and Maubeuge."
The great movement was begun by Haig early on Tuesday, 8th October. It was a wild, wet, autumn morning when Byng at 4.30 and Rawlinson at 5.10 attacked on a 17-mile front, while a French army extended the battle 4 miles farther south. The enemy resisted desperately, but nothing could stay the rush of the Allied infantry and the deadly penetration of their Tanks. By the evening Haig had advanced between 3 and 4 miles, and the Hindenburg zone was no more. The enemy was falling back to the Oise and the Selle, and for the moment his organization had been broken. Every road converging on Le Cateau was blocked with transport and troops, and our cavalry were galloping eastward to confuse the retreat.
Sir Douglas Haig's battle, which ended on the 10th October, may be considered the determining action in the campaign, and it has been described by Foch as "a classic example of military art." It had no defect either of plan or of execution. The enemy was fairly and clearly defeated in a field action. Foch had played on the whole front a crescendo of deadly music, and the enemy's strategic position was now so desperate that no local stand could save him. There was talk at the time of a German retreat to the Meuse. but it was an idle dream. Long before her broken divisions could reach that river Germany would be upon her knees.
