Up to this time poison gas had been unknown in the Dardanelles campaign, although all ranks were supplied with a small respirator which covered the nose and mouth and was secured with tapes that tied behind the head. It was understood that the British had, in reserve, effective means of retaliation should the Turk resort to it. However, on the 28th September, the enemy, who had been rather aggressive all day with shrapnel, bomb, and rifle fire, in the afternoon loosed a broomstick bomb, which burst in the air above the Apex and emitted a whitish vapour. This vapour drifted down into the trenches and had a decided lachrymatory effect on those with whom it came into contact. It passed off in a few minutes, and no further bombs of that nature arrived. The incident was important enough to warrant a report being made to Divisional Headquarters. As a similar occurrence at Hill 60 was noted within a few days, some attention was given to anti-gas measures. The result was the issue of certain instructions and a new respirator (P.H.) which, made of cloth and provided with goggles, was worn over the head and gave the wearer the appearance of either a partly equipped diver or member of the Spanish Inquisition. This article was to be carried on the person at all times. The 29th September saw more activity on the part of the enemy, whose shrapnel fire seemed to increase in accuracy daily. Our own artillery, through lack of commanding positions for observation purposes, and also through scarcity of ammunition, was not able to reply effectively. At times a message would come from Brigade or Division to say that such and such a battery intended, at a given hour, to fire on such and such a target. The necessary preparations were made but the infantryman was inclined to be derisive when, at the appointed hour, the gunners would loose a few rounds only and then remain silent until the next day. Occasionally the infantry selected targets for the artillery--such as enemy working parties, enemy troops on the move, or occupied gun pits. One afternoon a platoon of the enemy was reported near the road leading into Anafarta Sagir. The gunners were telephoned, but their longer stay on the Peninsula had given them a better local knowledge, and they were able to point out that the target was the tombstones and shadows of a small cemetery.
