On the other hand battles such as the second phase of August 8th, the battle for Mont St. Quentin, and the later battles of Bony and Beaurevoir were not set-piece operations. Therefore the developments from hour to hour, and even from moment to moment, are full of intense human interest, and replete with tales of individual courage and initiative. Some day, when all the material has been gathered, an abler pen than mine will write their story.

If the reader will bear in mind all these considerations, with special reference to the battle of Hargicourt on September 18th he will realize that, in describing the dispositions, the objectives, the time-table and the preparations for the battle, I have told practically all that there is to tell of the course it took, except only as regards the results actually achieved, in ground won and prisoners taken.

It has been difficult, nevertheless, to refrain from dwelling in detail upon the performances and experiences in battle of the individual fighting men. Any attempt to do so would, however, prove hopelessly inadequate. The numbers engaged were always so large, their activities so varied, the conditions of each battle so different in detail, that to do adequate justice and avoid unfair discrimination would make impossible demands upon the space available to me.

Popular interest naturally centres upon the Infantry, not only because they are the most numerous, but also because they are invariably in the forefront of the battle and often in immediate contact with the enemy. Without the slightest disparagement to the important rôle of the Infantryman and to the valour which its performance demands, it must never be forgotten that the work of the Artillery, Engineers, Pioneers, Machine Gunners, Trench Mortars, Air Service and Tanks is in every way equally important and essential to the success of any battle operation. Yet it is equally true that no battle can be won without the Infantry.

In a deliberately prepared battle it is not too much to say that the rôle of the Infantry is not, as a rule, the paramount one, provided that all goes well and that there is no breakdown in any part of the battle plan. That does not, however, imply that the Infantry task makes no high demand upon courage and resolution. On the contrary, these are the essentials upon which the success of the Infantry rôle and therefore of the whole battle depends.

The primary duty of the Infantry, in an assault covered by an Artillery barrage, is to follow up the barrage closely. The barrage is nothing more nor less than a steady shower of shells, bursting over the very heads of the leading lines of Infantry, and striking the ground some 80 to 120 yards in front of them. This shower is usually so dense that three to four shells per minute fall on every twenty yards of frontage. It is so intense a fire that no enemy, however courageous, could remain exposed to it. It falls on one line for three or four minutes, while the Infantry lie down flat. Suddenly, the barrage "lifts" or advances 100 yards. At a signal from the platoon or company commander the whole line rises and rushes at top speed to catch up to the barrage, again to throw itself flat upon the ground.

So long as no enemy are encountered, these successive rushes may go on without check for hundreds of yards. If during the course of any rush, trenches or strong points are met with and they contain enemy who do not immediately surrender, prompt use must be made of rifle and bayonet. But it is the primary business of the leading line of Infantry to push on and not to delay by engaging in close combat. The second and third lines of Infantry are there to "mop up," that is, to dispose, by destruction or capture, of any enemy overrun or ignored by the leading line. Where Tanks co-operate that is also their special business, and when it has been attended to they go forward at top speed to rejoin the leading line.

In such a methodical way the advance continues until the final objective is reached. This event can be recognized by the Infantry in any of three ways, firstly by reference to the clock time; for the arrival of the barrage at any line on the map or ground occurs in pursuance of a definite time-table; secondly by the topographical features, and thirdly by the expedient of maintaining the barrage stationary at the final objective for fifteen to thirty minutes. In some battles, I also adopted the device of firing from every gun in the barrage, three rounds of smoke shell in rapid succession, as a signal to the Commanders of the leading line of Infantry to call the final halt, to select a good line for trenches, and to dig-in rapidly, a process technically called "consolidation."

It would be too much to hope that in an attack covering a front of four or five miles, every part of the line should be able to advance without any check whatever up to the final halting place. But the expectation always is that by far the greater part of the whole line will be able to do so. If, here and there along the front, platoons or even whole companies were to be held up or delayed by special difficulties or obstacles such as thickets, or copses strongly manned by the enemy, or by belts of wire, or village ruins, such breaks in the general line of advance would matter but little to the success of the operations as a whole. The gaps discovered in the leading line of Infantry, when it had come to a halt at the final objective, would be speedily filled by supporting troops from both flanks of the gap, and thereby the enemy holding out further back, would be completely enveloped. His surrender would follow as soon as he realized his position, and that he had been cut off from any contact with his friends in his rear.

Such is the normal course of the Infantry action in a pitched battle. It makes great demands upon the iron resolution of the Infantryman to push on vigorously against all obstacles, and to put forth his utmost physical powers to keep up with the barrage, especially when the ground is wet and sticky, or when uncut wire has to be crawled through. All this he must do, utterly regardless of the enemy fire which may be directed against him, whether from Artillery or machine guns. His best hope of immunity is always to make his rush rapidly and determinedly, and to get to ground immediately that he reaches the halting place, close up to the barrage, when signalled by his officer.
