It was not, however, at this point that the severest fighting of the battle occurred. Across the great tunnel to the north of Bellicourt, where the Canal passes for nearly two miles underground, ran the main Hindenburg system, carrying it eastwards over the Canal itself, and it was here that the fiercest resistance was put up. The two American divisions had the post of honour and led the advance. It was a heavy task, largely owing to the fact that it had not been possible to master the German outpost line completely before the advance started, and numerous small bodies of the enemy, left behind in machine-gun posts, tunnels, and dug-outs, were able to harass it seriously for a time. But the "Americans fought like lions"—how often I heard that phrase from our own men in France! The American losses were no doubt higher than would have been the case with more experienced troops, seasoned by long fighting,—so I have understood from officers present at the battle. It was perhaps partly because of "their eagerness to push on" without sufficiently clearing up the ground behind them that they lost so heavily, and that advanced elements of the two divisions were for a time cut off. But nothing daunted these fresh and gallant men. Their sacrifices, as Marshal Haig has recently said, addressing General O'Ryan, who commanded the 27th Division in this fight, were "made with a courage and devotion unsurpassed in all the dread story of this war. The memory of our great attack on the Hindenburg line on September 29th, 1918, in which the 27th American division, with troops from all parts of the British Empire, took so gallant and glorious a part, will never die, and the service then rendered by American troops will be remembered with gratitude and admiration throughout the British Empire."

That misty September day marks indeed a culminating moment in the history of the Empire and the war. It took six more days of sharp fighting to capture the last remnants of the Hindenburg line, and six more weeks before Germany, beaten and demoralised by sea and land, accepted the Armistice terms imposed by the Allies. But on September 29th, the war was for all practical purposes won. General Gouraud at the time was making his brilliant advance in Champagne. The Americans were pushing forward in the Argonne. Both movements were indispensable; but it was the capture of this great fortified system which really decided the war. "No attack in the history of the world, was ever better carried out," said Marshal Foch to Mr. Ward Price, in Paris, on April 16th last—"than the one made on the Hindenburg line near St. Quentin and Cambrai, by the Fourth, Third and First British Armies, on September 27th-29th. The enemy positions were most formidable. Nothing could stop the British. They swept right over them. It was a glorious day for British arms." It was also the climax of two months' fighting in which French, British, and Americans had all played to the full the part laid down for them by the history of the preceding years, and in which it fell to the British Army to give the final and victorious blow.

Non nobis, Domine!—non nobis!

It will, I think, be of use to the non-military reader if I append to the sketch I have just given of the last phase of the British effort, the following paragraphs written last January by an officer of the General Staff, in response to the question indicated in the opening sentence.

"I have been asked to say what in my opinion were the most critical and anxious stages of the series of great successful battles opened on the 8th August, 1918. The question is not easy, for the whole period was one of high tension, calling for continuous and unsparing effort.

"From one point of view, the opening battle east of Amiens was decisive, for it marked the turning point of the campaign on the British front. Its moral effects, both on our own troops and on the enemy, were far-reaching and give the key to the whole of the succeeding struggle. Nothing less than a sweeping success, such as that actually achieved, could have produced this result. The days preceding the attack, therefore, constituted a most anxious period. On the other hand, from the purely military point of view, our chances of success were exceedingly good. The attack was to be delivered by fresh troops, second to none in the world in fighting qualities, assisted by an unprecedented concentration of mechanical aids to victory. Preparations had been long and careful, every contingency had been thought out, and there was every reason to expect that our attack would be a complete surprise.

"Militarily, the more critical period was that which immediately followed the battle when, having reached the line of the old Somme defences of 1916, it was decided to switch the point of attack to the area north of the Somme. On the success of this manoeuvre depended whether the attack of the 8th August was to be a single isolated victory comparable to the battle of Messines in June, 1917, or whether it was to develop into something very much greater. The decision was a grave one, and was in some sense a departure from previous practice. The enemy was now on the alert, the troops to be employed had already been severely tried in the earlier fighting of the year, and failure would have called down severe criticism upon the wisdom of abandoning so quickly the scene of our first great success.

"It was only after the first days of heavy fighting (in the battle of Bapaume), during which progress was comparatively slow and the situation full of anxiety, that the event proved that the step had been wisely taken.

"Then, when the success of this bold manoeuvre had declared itself, and the enemy had begun the first stages of his great retreat, the next critical period arrived on the 2nd September, when the powerful defences of the Drocourt-Quéant line were attacked and broken. The effect of this success was to render the whole of the enemy's positions to the south untenable and to throw him back definitely upon the Hindenburg line.

"Undoubtedly the most critical and anxious period of the whole advance arrived at the end of September. The culminating attacks of the 27th and 29th of that month on the Canal du Nord and Hindenburg line defences shattered the most formidable series of field defences that military science has yet devised and drove the enemy into open country. These attacks, indeed, accomplished far more than this. They definitely broke the power of resistance of the German Armies in the field. In the battles which followed, our troops were able to take greater and greater risks, and on every occasion with complete success.
