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.
