It may be conjectured that, up to the period of the definite entrenchment of the two armies, the losses of the enemy were not greater than our own. It is in the attack that losses are incurred, and the attack had, for the most part, been with us. The heavier guns of the Germans had also been a factor in their favour. From the 18th onwards, however, the weekly losses of the enemy must have been very much greater than ours, since continually, night and day, they made onslaughts, which attained some partial and temporary success upon the 20th, but which on every other occasion were blown back by the rifle-fire with which they were met. So mechanical and half-hearted did they at last become that they gave the impression that those who made them had no hope of {186} success, and that they were only done at the bidding of some imperious or imperial voice from the distance. In these attacks, though any one of them may have only furnished a few hundred casualties, the total effect spread over several weeks must have equalled that of a very great battle, and amounted, since no progress was ever made, to a considerable defeat. Thus on September 19 there was a succession of attacks, made with considerable vivacity and proportional loss. About 4 P.M. one developed in front of the 4th and 6th Brigades of the First Corps, but was speedily stopped. An hour later another one burst forth upon the 7th and 9th Brigades of the Second Corps, with the same result. The artillery fire was very severe all day and the broad valley was arched from dawn to dusk by the flying shell. The weather was still detestable, and a good many were reported ill from the effects of constant wet and cold. The 20th was the date of two separate attacks, one of which involved some hard fighting and considerable loss. The first, at eight in the morning, was upon Shaw's 9th Brigade and was driven off without great difficulty. The second was the more serious and demands some fuller detail.
