We turned as soon as were able, and waited for the enemy to recommence the attack. He was all out now, and putting on top speed bore down upon us with the speed of an express train. Nearer and yet nearer he drew. Thankfully I noticed that we were both at the same altitude. When yet about a quarter of a mile distant, his observer opened fire, the bullets flying all around us in a leaden stream, and still we did not reply. I looked at my observer. He was bending over his gun, fumbling about with some portion of the mechanism. There was no need to ask what was the matter. Alas! I knew too well. The gun had jammed. Now followed a ticklish time for both of us, for without the gun we were completely unarmed, and Fritz was drawing nearer every second. Already I could hear and feel his bullets singing past my head, occasionally chipping portions of the machine. Now he was right level with us. What were we to do? To remain in that same position would mean certain death. If we climbed, he would climb faster, and would almost immediately be up with us again. There was only one thing to be done--the unexpected! So putting her nose-down, we dived towards the earth like a stone, and had gone over a thousand feet before I could get her level again. This maneuver so upset the calculations of the enemy, that he was now about three-quarters of a mile distant. This gave us precious time to prepare again for the attack. The observer was still working feverishly away, when we commenced to climb. Fritz had already turned and was coming down to meet us; but we had the advantage this time of having the wind behind our backs. If only that infernal gun were ready! Up we climbed, and down came Fritz; all the faster because he knew we were comparatively unarmed. Now we were under half a mile distant, now only a quarter, and now he had commenced to fire. Would we never reply? At last! Brrr! Brrr! Brrr! yapped the gun in our bows.
