About 8.00 A.M. we heard the sharp report of our anti-aircraft guns and observed the white puffs of smoke that the shell emitted as it burst around the German aeroplanes high up in the sky. All at once we noticed aeroplanes manuvring in the air and observed a quick diving motion from one of them which had opened fire on the one underneath, as the latter plane fell to the ground in a mass of flames. Afterwards the victor flew back over our lines, so we knew that another Hun aviator had fallen a victim to one of our R.F.C. men. At midnight our field guns were brought forward and began to fire from behind the railway embankment at the Hun trenches. It was not long before the Huns started to retaliate with gas shells. The slight wind that was blowing in our direction soon brought the vile fumes towards us. Without a moment's delay every one put on his gas helmet or small box respirator. We were then safe from the deadly gas fumes, but an occasional German shrapnel shell would burst over our heads. The Huns' artillery fire was principally directed against our artillery, but they could not locate them. We were now expecting the Germans to make an attack and were all in readiness to receive them. About 5.30 A.M., after being under the gas shell bombardment for about five hours, the air gradually got clearer and each platoon officer cautiously removed his gas mask to test the air. After finding it safe, they gave orders to the men to take their gas masks off. On April 14th the Huns had found out by their aerial service the position of our trenches, so in the afternoon they started to bracket fire our trench. That is to say, as they did not know the exact range, they observed by aeroplanes or observation balloons the effect of shells which their artillery had dropped first in front of our trench and then in the rear. Gradually working inwards, they located the trench. It certainly was an unpleasant feeling as these searching shells commenced to come nearer and nearer. A private who had been sent up with a ration party the previous night to take the place of a man who had been wounded, was in the line for the first time. He got very excited when the Huns started to bracket fire our trench and kept running up and down from one end of the trench to the other until he was tired out. Finally he decided he would not run any more and sat down to smoke a pipe. By this time the Germans had succeeded in getting the correct range of our trench. They sent over a shell which blew the poor fellow to pieces. Our S.O.S. signal had been sent back and the forward observation officer was now alive to the situation. It was not long before we heard the sweet music in our ears of the swish, swish of our artillery as the shells passed over our heads on their errand to the German batteries, which they soon located and silenced.
