and theoretically we can engage any target in our arc of fire. It is then essential to learn the country in hostile territory, and one looks out for likely targets and for points at which one can inconvenience the enemy by keeping him under constant harassing fire. This work must necessarily be done from a point of vantage where a good wide view can be obtained, and, in most cases, a house, tree, or high piece of ground well behind the lines, is selected for a Rear O.P.

In an incredibly short space of time every officer learns the country off by heart, and can bring any gun to bear on a particular target at short notice. At first Junior Officers are allowed practice shoots on targets well behind the enemy lines, and as they gain confidence and experience, are entrusted with "close shoots," i.e., firing on hostile emplacements, etc., in the front line, a job which requires extreme caution and accuracy, as "No Man's Land" averages not more than 200 yards in width in most places. Batteries can always communicate with Battalion Headquarters in the line, a wire, usually buried, leading from there to our Brigade Headquarters, and each Battery has its own private wire to the latter place. In the same way one can be linked up with nearly every unit in a Division by means of an Exchange run by the Royal Engineers.

A few days sufficed us to make ourselves quite at home, and officers went freely about "seeking whom they might devour," visited old established O.P.'s, and searched for new or better ones. It is a curious fact that the average subaltern is never fully satisfied with an O.P., and is always bent on discovering "something better," although in few cases is his ambition realised! One officer favours this O.P., another that, and on this occasion the one which our worthy Battery Commander had a preference for was a most unpleasant place, commonly known as "The Doll's House," though why so called no one could tell. At any rate, it was an abode to be avoided on all possible occasions, and the subalterns were quite convinced it was the registering place of all the hostile batteries within range and vision. At any rate, we daily found less and less of the building, until one day the staircase was blown away as well as the perch on top which afforded us our view. Great was the relief when the B.C. at last declared the O.P. "out of action" until further notice.

Nearly every O.P. has an appropriate name given to it, and so we repaired to "Stink Farm" after abandoning our old love! We put in most useful days of practice there, and the knowledge and experience gained was invaluable. Our thanks were due to the enemy for his consideration in allowing us to conduct our daily tasks almost unmolested: he showed himself to be most lethargic and sleepy, and did not waken up unless we were unusually energetic. Perhaps his chief reason for remaining so inactive was the absence of any heavy guns on our side. Our largest piece was a 60 pdr., and he may have thought mere Field Artillery beneath his consideration. Nor was he more active in the air; his planes rarely passed over our lines, and when they did, it was at so great a height that it was quite impossible for them to gather information. However, one day, we were extremely fortunate in seeing a hostile plane, that had ventured to cross over our lines at a lower altitude, brought down in flames by a direct hit from an "Archie" battery lying in wait close behind our own position. It is a rare sight, for, to tell the truth, anti-aircraft batteries are not held in particularly high respect by anyone except by those of their own ilk, and on only two other occasions did we ever see the like again.

Our fortnight soon sped by, and we were quite reluctant when the time came to go "out." We left our neighbours, who had befriended us so well, with the sincere hope that we would have the good fortune to meet and lie alongside of them again in the future. This hope, however, was not destined to be fulfilled. We retraced our steps through Merville and Aire to the same area from whence we came, to a village called Nielles, in order to concentrate as a Division, which, when formed, was designated the Guards Division.

The inhabitants, as usual, extended a warm welcome to us and showed us every consideration, and we settled down to enjoy the peaceful surroundings bathed in the warm and pleasant September sunshine, while the Senior Subaltern availed himself of the opportunity of again laying siege to the hearts of his former conquests at Seningham close by. Our own C.R.A. came to visit us here, and the officers were severally introduced to him. He expressed satisfaction at the report which came to him from the line, concerning our conduct in action, and added that the high opinion formed of us at home had in no wise been diminished, and that our reputation merited the distinction conferred on us of being selected as the Artillery of the Guards from among the many units of the new Army.

Thus we waited, confident in the belief that, whatever we were in the future called upon to do, we would at least put up a good show, and determined to be a credit to the Division of which we now formed a part. We had not long to wait, whispers passed round that we would be up and doing at no distant date, and these rumours proved to be well founded.

CHAPTER II.

Our First Battle.

Our marching orders came within the next few days. Each unit was provided with portable bridges, which were carried under the wagon bodies, and this, and several other preparations, gave us a good indication that we were out for business. A couple of days trekking brought us to the village of Nedonchel, which proved to be another place of happy memory to our Senior Subaltern. Here we were given a rough idea of the part we were to play in the coming proceedings. Two army corps were to attack, on a six mile front, in the neighbourhood of Loos and, if the assault was successful, the corps in reserve, which included our Division, was to go through and exploit the victory to its fullest advantage. We were to take no part in the initial attack.

Large masses of troops were being moved up behind the battle area, and, in order to screen our movements from hostile aircraft, the latter stages of the journey were to be made under cover of darkness, so the whole of the next day was spent in resting. At nightfall a diversion was caused by a Cavalry Division passing through the village on its way up, and a splendid sight it presented, as one famous regiment followed swiftly on another. It was now almost time for us to make a start, and the good lady of the house had remained out of bed to brew us hot coffee and see us off the premises. As we were about to depart she told us that her old mother, aged 88, who was in the next room, had expressed the desire to see us for a moment, and so we were conducted to the old lady's bedside. She was lying telling her beads, but sat up as we approached and beckoned to each officer in turn, who advanced, knelt, and received a blessing. The inhabitants knew well that a big battle was to be fought quite soon, as the little village had been the scene of great activity during the past few days and, although it was a considerable distance from the line, the preliminary bombardment could be distinctly heard. The low muffled rumble was incessant, and, to-night, seemed, if anything, more intense. Shortly after midnight we set off and disappeared into the darkness, followed by words of good cheer from the villagers and shouts of "Bon chance, messieurs, bon chance."

Passing through Bruay we arrived a few miles behind the battle front on the morning of the assault, which was delivered at an early hour, and soon the news came back that, so far, everything was going well; the village of
