Stories of this kind, however, combined with the effects which we ourselves were experiencing, made us realise that protection against tear gas was essential, and for this purpose arrangements were made to supply every officer and man in the front line with a pair of anti-gas goggles. The earliest types of these goggles were very simple in construction, and we are told were copied from a French pattern. They consisted of a waterproof fabric lined with flannel containing a wire spring for the nose and fitted with celluloid eyepieces. By bending the wire to the shape of the nose it was possible to close the nostrils and at the same time give a reasonably good fit to the flannel on the face. In some cases the flannel was anointed with some kind of grease so as to make a still closer fit, in order to keep out small traces of gas which are quite sufficient to produce lachrymation. Later on we had a much better type of goggle backed with rubber sponge to make a tight fit to the face. With the small numbers of gas shell used against us we had no experience of any effect on the lungs, and it was found also that the helmet form of respirator was enough to keep out, at any rate, low concentrations of the lachrymator; but we got a rude awakening when the boche began to use his tear shells in larger numbers. Such a case happened to us in the beginning of 1916, at the celebrated village of Vermelles, a little ruined town just behind the lines near Loos. The enemy tried out an attack on us over about a mile front for the purpose of bagging some of our trenches, and he attempted to keep reinforcements from coming up to counter attack him by putting down a tear-shell barrage through Vermelles and north and south of it over the roads on which our fellows would have to advance. He used thousands of his tear shells and the neighbourhood absolutely stank of them. Fortunately, it was almost impossible to put down an effective standing barrage with gas, and our reserves got through on two roads that had not been blocked effectively. The boche attack was a fizzle, but Vermelles was a little private hell of its own for that day and most of the next forty-eight hours as well. During and immediately after the bombardment, troops passing through the village wore both goggles and gas helmets, but the concentration of lachrymator was so great that many of our fellows were sick and actually vomited inside their helmets. If you can imagine men going up to a battle with these flannelette bags over their heads and then being sick inside them, you can realise that the boche was not particularly popular with us at the time.
