May 10th, 1915.
We got here to refit and rest this morning at 4, having marched last night at 10. The general impression in my mind is of a nightmare. We have been in the most bitter of fights. For seventeen days and seventeen nights none of us have had our clothes off, nor our boots even, except occasionally. In all that time while I was awake, gunfire and rifle fire never ceased for sixty seconds, and it was sticking to our utmost by a weak line all but ready to break, knowing nothing of what was going on, and depressed by reports of anxious infantry. The men and the divisions are worthy of all praise that can be given. It did not end in four days when many of our infantry were taken out. It kept on at fever heat till yesterday.
This, of course, is the second battle of Ypres, or the battle of the Yser, I do not know which. At one time we were down to seven guns, but those guns were smoking at every joint, the gunners using cloth to handle the breech levers because of the heat. We had three batteries in action with four guns added from the other units. Our casualties were half the number of men in the firing line. The horse lines and the wagon lines farther back suffered less, but the Brigade list has gone far higher than any artillery normal. I know one brigade R.A. that was in the Mons retreat and had about the same. I have done what fell to hand. My clothes, boots, kit, and dugout at various times were sadly bloody. Two of our batteries are reduced to two officers each. We have had constant accurate shell-fire, but we have given back no less. And behind it all was the constant background of the sights of the dead, the wounded, the maimed, and a terrible anxiety lest the line should give way.
During all this time, we have been behind French troops,and only helping our own people by oblique fire when necessary. Our horses have suffered heavily too. Bonfire had a light wound from a piece of shell; it is healing and the dear old fellow is very fit. Had my first ride for seventeen days last night. We never saw horses but with the wagons bringing up the ammunition. When fire was hottest they had to come two miles on a road terribly swept, and they did it magnificently. But how tired we are! Weary in body and wearier in mind. None of our men went off their heads but men in units nearby did -- and no wonder.
