Out in the open—The enemy limited to passive defense—And relying on machine-gunners—Their elusiveness—Problems of the offense—Slowing down—Up with the infantry—Why dispersion—Liaison up, down, and across—How keep the staff informed?—The spent wave before Montfaucon.

What of the infantry lost to view in the folds of the landscape? They were confronting the originals of the hills, woods, and ravines, whose contours on paper had been the definite factor in making plans, while the character and resistance of the enemy had been the indefinite and ungovernable quantity. As the day advanced, irregular pencilings, reflecting the reports of the progress of the fighters, moved forward on the maps of the different headquarters toward the heavy regular lines of the objectives which were the goals of our high ambition.

The loss of the first-line fortifications to the Germans could not be considered as serious as in an offensive in the first years of the war. Even as early as the Verdun battle, proponents of the mobile school of warfare, who had never been altogether silenced by the engineering school, had advocated a yielding elastic defense, which, after drawing the Crown Prince's Armies away from their depots, would counter by a sudden attack of the gathered French forces; but such a maneuver was too daring and contrary to the thought of the time, with its dependence upon rigid defense. Infantry had fallen into the habit of feeling "undressed" and helpless unless in trenches. When the soldier was forced into the open, he had hastened to hide his "nakedness" in a shell-crater, or instantly, in the very rodent instinct that he had developed, set to digging himself a pit. Since the German offensive of March, 1918, all the practice had been to wean the infantry away from settled defenses to the supple use of light artillery, trench mortars, and machine-gun units. Happily, as we know, the basic training of our infantry had been in keeping with this idea.

In the palmy days of German numbers and vigor, the German High Command might have met our Meuse-Argonne offensive by the prompt marshaling of reserves for a decisive counter-attack against our extended forces with inadequate roads at their backs; but if Ludendorff realized the errors which our fresh troops might commit from inexperience, we realized, on our part, that he was too occupied elsewhere by Allied attacks to consider any considerable aggressive action on our new front, where his tactics must have in mind, obviously, the protection with a minimum cost of men and material of his lines of communication, in order to assure a successful withdrawal from northern France and Belgium. With our attack developed, his subordinate in the Meuse-Argonne sector, in carrying out this policy, would choose the points where he could gain the best results by concentrating the fire of the artillery at his command, and then depend upon the expert German machine-gunners for defensive warfare in the open, supported by such fragmentary defense lines as might be hastily constructed.

According to the German intelligence report of our operation at Saint-Mihiel, our staff work had been immature, while our line officers did not know how to make the most of our gains. Without considering that at Saint-Mihiel we were under orders to stop on our limited objectives, and granting the Germans their view, no one will deny them the credit of knowing how to make the most of their tactical opportunities. The bellows of our accordeon was being drawn out as theirs was drawn in. With every hundred yards of advance our men were farther from their communications. Reports were accordingly the longer in reaching headquarters, and orders for future moves the longer in reaching the line, while those of the Germans, as they fell back on their communications, were prompt.

It was not the first time that they had lost first-line fortifications. They knew by experience as well as observation what had happened to their first line under the powerful initial assault; and they knew what they had to do, in full dependence upon a staff system trained in practice to meet this as well as the other vicissitudes of war. The failure of their men in the front line to stand to the death was an irritating exhibition of deteriorating morale, which must be taken into consideration not only by the subordinate but the higher commands. Scattered and demoralized individuals and groups, filtering back in retreat, might be re-formed, or passed through advancing reserves to the rear for reorganization. Fresh machine-gun units, which had almost the mobility of infantry, could be readily placed at points already foreseen as most suitable. One machine-gun might hold up the advance of a company of infantry. The enemy was fully familiar with the details of a landscape studded with ideal machine-gun positions, the choicest being the edge of a woods on a hillside overlooking an open space.

Some of our officers and men had met German machine-gun practice in open warfare in the ChÂteau-Thierry campaign and at the British front. As others knew it only under the limitations of trench warfare, the resistance which they now must face was familiar to them only through instruction. The German machine-gunner, having learned as the survivor of many battles the art of self-preservation at his adversary's expense, would wait all day and all night and even longer without a shot, until his target appeared in the field of fire assigned to him; wait as a Kentucky feudsman waits behind a rock for his enemy to appear on a road. Each gun was only one in a well-plotted array covering all the avenues of approach which any attacking force must follow. The guns disposed in front might precede or wait on the guns in flank in opening fire.

There was nothing new or wonderful in this arrangement. Any soldier with a sense of ground and of natural combative strategy could work out a plan of interlocking fire; but the discipline and the training requisite to its proper execution, and the stubborn phlegmatic bravery which sticks to a machine-gun to the death, are not to be found at random on any page of a city directory or social register. The fact that a gun had begun firing did not mean that it could be immediately located. Sometimes when light conditions were right the flash was visible, unless the gunner had hung a piece of bagging, through which he could aim, to conceal the flash. The direction of the fire might be judged somewhat by sound, and also by observing the spits of dust in the earth or on the wall of a building. Judgment on this score was affected by the proximity of the passing bullets to the observer's person.

The more machine-guns were firing from different angles, the more difficult it was to locate any one of them by either method; and the more influential the human element. In the midst of their fire imagination easily multiplied the number of guns, which is one of the moral effects of their use. When a gun was located, the gunner might slip back behind the crest of a ridge, or he might have moved as a precaution, before he was located, to another position which had been chosen as his next berth, with pit and camouflage in readiness.

An experienced aviator—always there is that word "experience" which has no substitute—might detect a machine-gun nest if he flew low; but not as a rule in woods or in bushes, or even in the open when covered with green branches. There were many machine-gunners and relatively few aviators. If a gunner thought that an aviator who flew low had seen him, he might have taken up a new position before the aviator's information had brought down artillery fire. The machine-gunner was a will-of-the-wisp with a hornet's sting, which could be thrown a mile and a half. Usually the price of locating him was casualties to the infantry, and still more casualties before he was taken, if he stood his ground. If the Germans had not enough machine-guns back of their first line for a complete interlocking defense on the first day of the battle—and they certainly had later—they aimed to place them where they could do the most good.

Naturally the American Army, studying its chessboard, had taken into consideration the counter-moves of the enemy which would result from its attack. Of course the passage through the entanglements would lead to the first dislocations of liaison; the storming of the trenches to more; and the passage over the shell-craters to still more. After every offensive against the trench system, officers had studied how to avoid the slowing down of the attack after the first line was taken. This had led to passing the first wave promptly through the trenches and leaving a second wave to "mop up" by "breaching" dugouts and cleaning up points of resistance; and then to the system of "leap-frogging," in which, when the men in front had been weakened in numbers by casualties and lost their aggressive cohesion, fresh troops went through them to carry forward the attack. Reserves in passing through the lanes of the barbed wire and over the trenches and on to catch up with an advancing line also suffered from disorganization, which might be increased by strong concentrations of enemy shell and machine-gun fire.

A division commander had discretion as to how he would gain his objectives, which brings us into the field of tactical direction, as technical as it is vital to success. His dispositions were a test of his knowledge of his profession, and his handling of the division after it was engaged of his qualities of generalship. In some instances villages and strong points were passed by the main line of advance, and left to be conquered by special attacking forces. Instructions had not only to be elaborate but practical.

Those captains and lieutenants, the company and platoon commanders, who were carrying out the instructions, must each be a general in his own limited field. The less experience his seniors had in preparing practical instructions, the more he might suffer for his want of experience in leading men in battle. With the conquered trenches behind him, he had to make sure that his men were in hand, and if he had been allowed no time for reorganization behind his shield, that was an error; for barrages might move too fast, in expressing the desire of commanders for speed. At the same time, the line officer had to identify by the map the ground on his front which he was to traverse and the positions he was to take as his part in that twenty miles of pulsing, weaving, and thrusting line.

When you are seated before a table in calm surroundings, trying to follow the course of one company in an advance, you realize the limitations of your 1 to 20,000 map. It ought to be 1 to 10. More elements than any layman could imagine entered into the problem of the location of the command post from which a battalion commander was to direct the movements of one thousand men, or a regimental commander of three thousand, in action. All this, of course, represents sheer fundamentals in thoroughgoing military science; but we must have the fundamentals if we are to appreciate the accomplishment of our young army in the Meuse-Argonne battle.

A prominent hill was easily recognized. If a village were in the line of your attack, that was a simple guide; but in a region where, unlike our country of scattered farmhouses, the farmers all live in villages, there was a paucity of buildings which might serve as landmarks. One of our men expressed the character of the terrain by saying that with every advance it all looked alike—hills, ridges, woods, and ravines; yet when you came close to the part which you were to attack it seemed "different from any other and a lot worse." We had to cross brooks and swamps as an incident to conquering the other features of the landscape. If we missed any kind of fighting on the first day of the battle, it was in store for us in the later stages.

Oh, that word liaison! That linking up of the units of the attack in proper coÖrdination! Is there any man of the combat divisions who does not know its meaning or who wants to hear it again? It never came into slang at home in the same way as camouflage; but it is a thousand times more suggestive of the actualities of war. Liaison between the French and the American armies, between corps, divisions, brigades, regiments, battalions, companies, platoons, squads, and individual soldiers. Liaison between infantry and artillery and trench mortars and planes and tanks! If you did not have it, why, the adjoining commander might be as much to blame as you, at least, and you could say that he was altogether to blame. It may be said that the history of the war will be written in terms of positions taken, and of positions which were not taken because coÖperating units failed to keep their liaison. They were not up. When I mention that there were difficulties of liaison in writing of any division, I am not saying who was at fault, as no one person was, perhaps, more than another.

Other generals might be promoted and demoted, but General Liaison remained the supreme tactician. "Establishing liaison" was fraught with more heartaches and brain-aches than any other military detail. Men prowled through the night in gas-masks under sniping rifle and machine-gun fire and artillery fire, to ascertain if the unit supposed to be on their flank was there: perhaps to receive a greeting from an officer hugging a fox-hole, "Why aren't you fellows keeping up with us?"

Liaison was most difficult in woods, though the fighting was not necessarily always the severest there. Men naturally took to the paths instantly they advanced into woods, and these, if they were not stopped by machine-gun fire, advanced ahead of those in the deep underbrush. A stretch of unseen wire might arrest a part of the line, without the men in liaison on the right and left, as they plunged through the thickets, knowing that it had been stopped. The sheer business of keeping any kind of formation was distracting enough, without the sudden bursts of machine-gun fire, which might be so powerful that there was nothing to do except to take cover and consider a plan for silencing or capturing the gun. Unless the casualties were so serious that it was suicidal not to halt and mark out a plan for capturing the nest, and as advancing was a sure way of locating machine-guns and a prompt way of overwhelming them, we swept on in the spirit of our instructions and impatience. Captured machine-guns littered the paths of our battalions, in tribute to the effect of our impetuous rush upon gunners who continued to forget their orders to stand to the death when they saw the tidal wave of our soldiers about to swamp them.

As the day wore on and the enemy began to recover from the shock of the surprise of our initial onset, we encountered an increasing volume and fury of machine-gun fire from hill to hill across valleys, sweeping down ravines, plunging from crests and by indirect aim over crests, from village houses and from both directions where village streets crossed. At critical points it was supported by concentrations of shell-fire. Along that road, at the edge of this patch of woods, along that stretch of river bottom, the German's artillery laid down barrages over a space already swept by bullets, to hold positions by which he set as much store in his plans as we in ours.

"Why aren't you getting on?" division commanders asked, or tried to ask—as communication did not always permit the message to arrive promptly—when the pencilings on the map were not keeping up to the schedule of progress toward the objectives. It was an easy question; the answer might be in the lack of resolution of a regimental or battalion commander, in the character of the resistance to his troops, or in their disorganization under new and severe trials. After further ineffectual efforts the battalion and regimental commanders might say that progress was impossible without reserves.

Should the division commander send them? Expending his reserves on the first day of a long battle might place him in a dangerous position in face of a later and graver emergency; but he had the word of a subordinate that they were necessary. Had that subordinate in his first serious engagement become too readily discouraged? What was the extent of his losses? They were a criterion for judging his balance of assets for continuing the attacks, though they did not include the exhaustion of the men, their mood of the moment, or the disruption of liaison of their units.

The division commander might sit rigid with the front of Jove, which he thought was the chief item of the military formula, and say: "I want no excuses. Take the position!" Or he might keep on pressing in his reserves, in the determination that his division would be up on time; for Corps Headquarters were depending on him. The pencilings moving toward the corps objective were his record in the battle. If the pencilings were in a V-shape, that was bad. It meant that some of his elements were in a salient, in danger of being "squeezed."

Sometimes the pencilings were farther advanced than the troops. The wish being father to the thought, observers who saw a charge entering a woods took it for granted that it would go through the woods. Aviators sometimes mistook German soldiers in movement for our own; again they misread the maps, and placed our troops on a ridge ahead of their actual position. Company leaders might make the same mistake. The incentive to "get there" involved eagerness to send back word that you were arriving. A little group of gallant men who pushed through a wood or gained a crest might have been swept back by machine-gun fire by the time their proud report had reached division headquarters. Instead of having commanding ground as a "jumping-off place" for the next stage of advance, they might be hugging the reverse slope, exposed to fire from three sides immediately they showed themselves.

Regular as well as reserve officers who had never before been in action were to prove again that no amount of study of the theory of war, invaluable as it is, may teach a man how to keep his head in handling a thousand or three thousand men under fire. West Point cadet drill, Philippine jungle and "paddy" dikes, Leavenworth staff school, army post routine, and border service had no precedent of experience for the problems of maneuver which they now had to solve. It was all very well to say that the men were all right; but another thing was keeping your men together. I saw a regular colonel violating, in a singular reaction to amateurishness, the simplest principle of organization—the same that keeps subordinates informed of the location of a business superior—by having no post of command where he or an adjutant could be found with orders or reports. Some colonels remained steadily at their headquarters, without absenting themselves for personal inspection in any emergency; others moved restlessly about the field, trying to apply to three thousand men the personal direction of a platoon commander. Every subordinate who witnessed such an exhibition by a superior was bound to lose confidence in the command. I am not thinking of a lack of physical bravery when I say that there were instances of colonels and brigadiers voicing pessimism in the presence of subordinates. They might have become good judges or good philosophers, but they were not meant by nature, at least in their lack of battle experience, to drive home an ambitious offensive movement. Others had too much blind initiative; they were the kind that would drive head downward at a stone wall. Others were amazingly cool, determined, and efficient. These the men would follow against any odds.

Being human, our men who symbolized the pencilings on the map had muscles and nerves which were subject to fatigue. They had no visualization of their goals. If they could have been shown a flag on a mountainside, which they must reach before they "knocked off" for the day, the incentive for keeping on would have been more directly applied. All they saw was the slope or woods ahead of them. Their knowledge of the battle plan was limited to their orders to keep on going. After nights when suspense and suppressed excitement had allowed them little sleep, they had been going all day from 5.30 in the morning—going through barbed wire and trenches, over uneven ground, as they fought their way not only under fire but under the strain of that wearing mental concentration of trying to remember and apply all they had learned in their training and in previous actions.

Physically, the task set for our troops had seemed almost superhuman. Many had taken enough steps to cover in a straight line twice the distance they had traveled. To the eye of a hurrying observer, these myriad figures, whether dashing toward a machine-gun nest, or ducking to avoid an outburst of fire, or coming wounded across the fields, had the attraction of the ardor and fearlessness of youth in battle, while they brought many thoughts which were as far from the battlefield as the homes that had sent them forth.

We might say "check!" to the Germans if we had taken Montfaucon at the end of the first day. Montfaucon was the highest point on our way to the Lille-Metz railway except the Buzancy heights. It was visible from the old first-line trench system at Malancourt and from the Mort Homme on the banks of the Meuse, and it looked forward over the ground of the projected second day's advance.

It happened that I knew by travel that day how far it was from Headquarters to the front line. I might feel as well as appreciate the reasons of the officer and the soldier for disappointing Headquarters when I came to the end of my journey, where the tidal wave, expending itself, had left a platoon of infantry, without touch with the units on their right and left, washed up in a sunken road on the reverse slope of a hill in front of Montfaucon. On the bare crest of the hill lay the bodies of comrades who had fallen when the watchful German machine-gunners aimed at the human targets appearing in bold silhouette on the sky-line. It would have been madness for a handful of men without support to continue on against such blasts of cross-fire. They had fallen back, bringing their wounded, to await orders. Apart from the opposition they had met, the irregular landscape over which they had advanced was sufficient explanation of their inability to keep their liaison. It made islands of the hills as it diverted the tidal wave into the channels of the ravines. Scattered American soldiers were moving about the neighborhood like hunters, beating up Germans who had taken cover among bushes and in holes.

There was a recess in the battle in the vicinity, with stretches of several seconds when the countryside seemed quite peaceful. Then for another quarter of a minute, only a single machine-gun might be firing with deliberately precise intervals between shots. Suddenly the whole pack broke into full cry at the sight of quarry on the ridge which forms the southwestern approach to the town from the Montfaucon woods. We must have this ridge before we took the town. As I looked in this direction, I saw a line of our men appearing above the crest, each figure sharp against the light blue sky. Their intervals seemed at first as exact as the teeth of a comb; then the teeth began to drop out as figures fell. For a few seconds longer the survivors strove against the blasts before they drew back and faced right and moved along under cover of the slope, apparently seeking a less exposed portion of the crest for another attempt.

The machine-gun fire died down into spiteful irregularity until the line wheeled again toward the crest. Their heads were hardly above it when, with the unity of an orchestra answering the conductor's baton, the diabolical whirring rattle began again with all its previous volume. Evidently quite as many guns had this portion of the ridge under their fire as the other. This time the men did not persist. In proper tactical wisdom they disappeared from the sky-line as quickly as a woodchuck dodges into his hole.

We had now definitely developed the strength of the enemy at this point. Possibly we had located some of his machine-guns. At least, a battalion commander had learned enough to realize that he must undertake a deliberate method adapted to the situation for silencing them, which of course meant delay in pushing forward toward the day's objective the pencilings in one small section of the Headquarters map. Yet it was such details as this, revealed to me in a pantomime of vivid and stark simplicity and brevity, which taken together made the whole for that abstraction to the soldier which is called the High Command.

"Is Montfaucon taken?" was the question of Headquarters when I arrived there in the evening. Some reports indicated that it was. This part of the line was the most extended, and its communications accordingly the most uncertain. There were other pencilings on the map which also had to be erased. If we had not gained all our objectives, this was not saying that we had not been astonishingly successful. Having, as it were, set out ambitiously to take the whole solar system between dawn and darkness, one of the planets still held out, with the fixed star of Buzancy heights in the distance.

There might be many small salients, but none of threatening importance in our new line. Despite the uneven battle experience of our divisions, all had done their part magnificently. Our gains were more than a mile on our flank to four miles in the center, where we had made the bulge toward the summit of the whale-back. How far had we expended our momentum in our initial onset? What was the traffic situation? What of the morrow?
