Into this congestion the boche let off his gas on the eighth of August about ten o’clock P. M. It says worlds for the steadiness of our fellows that the total casualties from the three waves he sent over remained at the same low ebb that they had reached in the June attack. Of course but for the adverse circumstances they would undoubtedly have been still lower. It is interesting to note that the position on which the attack was made--namely, the line between Bellewarde Lake and the Yser Canal--included much of the line over which the first attack of all had been made a year and a half previously. The intensity of the cloud can be realised from the fact that helmets had to be worn at a division headquarters nine miles from the point of discharge, and the gas was perceptible, though not so dangerous, many miles beyond this point. The most distinctive feature of the whole affair was the number of men who suffered from the delayed action of the phosgene and collapsed several hours after the attack, especially if they had taken any exercise or eaten a heavy meal in between. The latter is not very likely, though it does occur, for a man even slightly gassed with phosgene feels very depressed--“fed up” and not particularly inclined for a hearty meal. But the getting of the exercise is only too easy, what with the necessary work in the trenches and the possible walk back to the aid post or the march back to rest billets in the event of a relief. It was men who had done this kind of thing who suffered most. After the attack we received official orders that no man suffering from the effects of the gas should be allowed to walk to the dressing station, and that if possible after a gas attack troops in the front trenches should be relieved of all fatigue and carrying work for twenty-four hours. It was also ordered that during the passage of the gas all movement should be reduced to a minimum and there should be as little talking as possible. These were very wise orders, for there had been too many officers and noncommissioned officers gassed through moving up and down to control the positions of their men and from shouting orders through their helmets. A certain amount of talking is necessary, of course, but too much of it makes a man breathe more deeply and may be just the added strain sufficient to affect his heart and cause his collapse. Of course after a gas attack there are always a certain number of malingerers--“Skrimshankers,” as we call them--who affect to be gassed in order to get away from the line for a bit. These are generally spotted easily enough by the doctor men. One medical officer I knew, harassed by the number of slightly “gassed” cases who would have to be evacuated, and suspicious about the genuine character of some of them, handed round cigarettes. All those who accepted and smoked their cigarettes were kept back. Later examination showed that he was right in every case.
