On the night of October 5th the 30th Division, which had suffered far less than the 27th, relieved the Australians. The job was finished; on this part as on the rest of the British front, the once glorious Hindenburg line was left behind, suddenly become a somewhat frowsy irrelevance of deserted trenches, dugouts, shell-craters, and tangles of barbed wire. With its passing one knew that, for the northern half of the front, there was no question of stopping; careful, methodical planning, mindful of the necessary vigorous thrusts at the key positions of railway centers and canal and river defenses, would irresistibly sweep the enemy back to the Meuse line, while the slower movement "down below"--as the French and American fronts seemed from the north--would question his ability to stand even there. Not that there was to be any spectacular rush about the movement, though one looked expectantly at the fitness of the British cavalry, which was always kept ready; the German staff could be expected to handle itself in this its most serious emergency. The spectacular and amazing thing was the steady, unruffled forward movement of millions of men, glacier-like in its assuredness. The temper of victory revealed itself in the eyes and bearing of the men who had waited four years, and who now saw Ypres disengaged, Lille on the point of recovery, Lens, Cambrai, Saint-Quentin restored to France. Americans might feel out of place in the midst of rejoicings, the depth of which they could not measure because they had not known the suffering which had gone before. The Second Corps was now to take part in the advance of one French and three British armies which, by November 1st, was to expand until the whole line from the sea to the Argonne was in motion. From north of Cambrai to south of Saint-Quentin the line was to reach its apex before Le Cateau in the attack of October 8th-10th; on the 14th the Franco-Belgian and British attack north of Lille was to start bringing the line up to this level; from the 17th to the 25th the southern British and French armies would again take up the offensive to the gates of Valenciennes, while the French armies "around the corner" on the right would have passed over the Saint-Gobain bastion and straightened out the corner.
