Index 156 Preface. I first met the 7th Manchesters early in May, 1917, when they were gaining new experiences of warfare on the Western front, not far from Epehy in the north of France. They, with the rest of the 127th Infantry Brigade, and in fact the whole of the 42nd Division had already had a long war experience in Gallipoli and Egypt, but they had only recently been transferred to France. I was taking up the command of an Infantry Brigade for the first time. I did not know then what a lucky man I was, but it did not take me long to find out, and we worked together without a break from that time until the armistice. The writer of this book passes over with considerable sang froid a certain operation which took place on a June night in 1917. If the 7th Manchesters, and not only the 7th, but the 5th, 6th and 8th as well will allow me to say so, I did not enjoy the same complete confidence as to the result before and during the night in question. The operation consisted of digging a complete new front line trench, a mile long, on the whole Brigade Sector, five hundred yards in advance of the existing front line, and half way across No Man's Land. June nights are short and it needed practically the whole brigade to get the job done in time. We had to find not only the diggers, but the covering troops and strong parties for carrying and wiring. Now four battalions digging on a bare hillside within point blank range of the enemy's rifles and machine guns are not well placed to meet attack or even to avoid fire if they are caught. So everything possible had to be done to avoid raising any suspicion of what was on foot in the minds of the watchful Germans. The troops had to work at high pressure and in absolute silence. The R.E. who were to lay the tapes were the first to go forward after the covering troops; then came the wire carriers, and, as soon as the R.E. had had time to get the tapes into position, out went the diggers, who, after reaching the line, had to be spaced out at working distances along the whole front. We who stayed behind spent some anxious hours. However complete the arrangements and however perfectly executed there was yet a chance that some enterprising and inquisitive German patrol might find out what was happening in time to give one of their local commanders an opportunity of hindering our work. We had to make such arrangements as would give the appearance that we were doing nothing unusual, that we were in fact excruciatingly normal. There must be neither more noise nor less than on an ordinary night, and so the artillery and machine guns must fire their accustomed bursts into the likely places in the German lines.
