You send your gas officer up to test. You go up yourself and generally know as much as the gas officer. Our general experience was that the first gas casualties we had were the gas officers. You decide that, as nothing has developed up to this time, it is probable that if any attack is planned by the Huns it is not intended to take place this morning. You get your men out of the heavily gassed areas and try to determine where is the best place for them to be well protected, to cover practically the same territory, and not to be too much exposed to the gas. By this time they have been sweating in their gas masks for three hours or more with the usual number of fools and accidents contributing to the casualties. You carefully redispose them while a desultory bombardment by the Germans adds to the general joy of life. You get them redisposed. The wind changes, the gas is carried to the position where they are. You have to change them again. To add to the general complications, the chow which was brought up last night is spoiled. It has been in the gassed area and the men must go hungry until the next evening. You come back to your dugout and find that in some mysterious way the gas has gone down into the dugout, so you prop yourself in the corner of the trench and carry on from there. Altogether it is a happy and joyful occasion. Your one consolation rests in the fact that your artillery is now earnestly engaged in retaliating on their infantry. Speaking of artillery, there is one thing that always used to fill us, the infantry, with woe and grief. A paper would come up, reading, "Nothing to report on the (blank) sector except severe artillery duels." "Severe artillery duels" to the uninitiated means that the opposing artillery fights one with the other. This, however, is not the custom. Your artillery shells their infantry hard and then their artillery shells your infantry hard. This is an artillery duel. The infantry is on the receiving end in both cases. Our artillery was particularly good. General Summerall, who commanded, I have been told, preached to his men that the primary duty of that arm was to help the infantry, and that to do this properly in all war of movement they should follow the advancing troops as closely as possible. Once I saw a battery of the Seventh F. A. wheel up and go into action not more than two hundred yards from the front line. We, on our part, endeavored to call uselessly on the artillery as little as possible. At times our own artillery would drop a few "shorts" into us but this is unavoidable and the infantry felt too strongly what had been done for them to pay much attention. In one of the German dugouts we captured, a lieutenant told me he found a sign reading, "We fear no one but God and our own artillery."
