in carrying out our first ambitious plan under our own command.

After cutting the redoubtable salient, which had been a wedge in the Allied line for four years, we were to go through to Mars-la-Tour and Etain, threatening the fortress of Metz itself. This was to be the end of our 1918 campaign. Instead of wasting our energy in operations in mud and snow, we should spend the winter months in applying the lessons which we had learned in our first great battle as an army. Officers who had been proved unfit would be eliminated, and officers who had been proved fit would be promoted. All the freshly arrived divisions from home camps and all the personnel for handling the artillery, tanks, and other material of war which our home factories would then be producing in quantity, would be incorporated in a homogeneous organization.

AMERICAN OFFENSIVES AND OTHER OFFENSIVES IN WHICH AMERICAN TROOPS PARTICIPATED, MAY-NOVEMBER, 1918.

The spring would find us ready to play the part which had been chosen for us in the final campaign. On the left of the long line from Switzerland to the North Sea would be the British Army, striking out from the Channel bases; in the center the French Army, striking from the heart of France; and on the right the American Army, its munitions arriving in full tide to support its ceaseless blows, was to keep on striking toward the Rhine until a decision was won.

In the early days of September, with our troops going into position before the threatening heights of the salient, and with the pressure of the effort of forming in time an integral army increasing with the suspense as the 12th, the day set for the attack, drew near, some important officers, at the moment when their assistance seemed invaluable, were detached from the Saint-Mihiel operations. Their orders let them into a portentous secret. They were to begin work in making ready for the Meuse-Argonne attack. While all the rest of the army was thinking of our second offensive as coming in the spring of 1919, they knew that it was coming two weeks after the Saint-Mihiel offensive.

This change of plan was the result of a conference between Marshal Foch and General Pershing which planned swift use of opportunity. The German Macedonian front was crumbling, the Turks were falling back before Allenby, and the Italians had turned the tables on the Austrians along the Piave. Equally, if not more to the point for us, the Anglo-French offensive begun on August 8th had gained ground with a facility that quickened the pulse-beat of the Allied soldiers and invited the broadening of the front of attack until, between Soissons and the North Sea, the Germans were swept off Kemmel and out of Armentières and away from Arras and across the old Somme battlefield.

The communiqués were telling the truth about the Allies' light losses; at every point the initiative was ours. The Germans were paying a heavier price in rearguard action than we in the attack. It was a surprising reaction from the pace they had shown in their spring offensives. All information that came through the secret channels from behind the enemy lines supported the conviction of the Allied soldiers at the front that German morale was weakening.

Ludendorff, the master tactician, was facing a new problem. That once dependable German machine was not responding with the alacrity, the team-play, and the bravery which had been his dependence in all his plans. He had to consider, in view of the situation that was now developing, whether or not the Saint-Mihiel salient was worth holding at a sacrifice of men. He knew that we were to attack in force; he knew that in an offensive a new army is bound to suffer from dispersion and from confusion in its transport arrangements. If he allowed us to strike into the air, he could depend upon the mires of the plain of the Woëvre to impede us while the defenses of Metz would further stay our advance, with the result that his reserves, released from Saint-Mihiel, might safely be sent to resist the pressure on the Anglo-French front, either in holding the Hindenburg line or in the arduous and necessarily deliberate business of covering his withdrawal to a new and shorter line of defense based on the Meuse River. The German war machine, which had been tied for four years to its depots and other semi-permanent arrangements for trench warfare, could not move at short notice.

A generalization might consider the war on the Western Front as two great battles and one prolonged siege. For the first six weeks there had been the "war of movement," as the French called it, until the Germans, beaten back from the Marne, had formed the old trench line. Throughout the four years of siege warfare that had ensued, the object of every important offensive, Allied and German, had been a return to the "war of movement." After a breach had been made in the fortifications, the attacking army would make the most of the momentum of success in rapid advances and maneuvers, throw the enemy's units into confusion, and, through the disruption of the delicate web of communications by which he controlled their movements for cohesive effort, precipitate a disaster. The long preparations which had preceded the offensives of 1915, 1916, and 1917 had always given the enemy ample warning of what to expect. He had met concentrations for attack with concentrations for defense. The sector where the issue was joined became a settled area of violent siege operations into which either side poured its fresh divisions as into a funnel. Succeeding offensives, in realization of the limitations of a narrower sector,—which only left the advance in a V with flanks exposed,—had broadened their fronts of attack; but none had been broad enough to permit of vital tactical surprises after the initial onset. The attrition of the man-power of the offensive force had so kept pace with that of the defensive that the offensive had never had sufficient reserves to force a decision when the reserves of the defensive were approaching exhaustion. Moreover, the Allies had never had sufficient preponderance of men, ordnance, and munitions to warrant undertaking the enterprise, which was the dream of every tactician, of several offensives at different points of the front at the same time or in steady alternation.

Now from Soissons to the sea the French and British were developing a comprehensive movement of attacks, now here and now there, in rapid succession. This drive was not a great impulse that died down as had previous Allied offensives, but a weaving, sweeping, methodical advance. Not only was German morale weakening and ours strengthening, but attrition was now definitely in our favor. Ludendorff's reserves were all in sight. His cards were on the table; we could feel assured that we knew fairly well how he would play them. Our own hand was being reinforced by three hundred thousand men a month from the immense reserves in the American training camps. We could press our initiative without fear of being embarrassed by serious counter-attacks taking advantage of our having overextended ourselves.

Thus far, however, the Germans were still in possession of their old trench system, except at a few points; our counter-offensive had only been recovering the ground which the Germans had won in their spring and summer offensives. Now that the tide had turned against him, Ludendorff, if his situation were as bad as we hoped, had two alternatives, and a third which was a combination of the
