The day was hot, and the work was heavy, and mein herr captain paused for a moment to curse his uncongenial task, and take a long draught from his water bottle, of some liquor that certainly was not water. In the midst thereof he let it fall with a curse of rage and surprise, for there overhead, as if it had suddenly appeared from the clouds, was the form of a British aeroplane. “Himmel,” he exclaimed, “all our trouble wasted, they have our hiding spot discovered, and to-morrow morning they bomb us—ach!”

The worthy gentleman was not far out in his deduction, for the lynx-eye of the observer in the aeroplane had carefully noted the exact geographical position of that new ammunition park, before the machine sped off homewards. But he was wrong to a certain extent; our Flying Corps are no fools, and they realized that Mr. Bosche would soon expect a return visit, and would be fully prepared therefor. This course was, therefore, useless to them; it was essential that that ammunition park must be destroyed, but in a manner and at a time the Germans least expected, and this is how it was accomplished.

Towards evening a light scouting machine sped swiftly away from a certain British aerodrome, only a few miles behind the firing lines. No untoward incident that, but it was particularly conspicuous from the fact that the entire aerodrome had turned out to wish the trip God-speed, to wish the pilot, a young second Lieutenant of the Canadian Infantry, the best of luck, and to cram the fuselage of the machine with spare ammunition, until she could barely “stagger” off the ground. The objective was the ammunition park already mentioned. With long, sweeping circles the scout soon cleared the area of the firing lines, and arrived over the wood.

Still nothing happened, the whole countryside was remarkably quiet for a battle area. No anti-aircraft guns fired, no enemy aircraft came humming round. Lower came the pilot to investigate. Still nothing happened; he, on his part, now began to feel genuinely alarmed, unless of course that confounded observer had been “seeing” things, a not unknown failing with aeroplane observers.

Meanwhile in the midst of the wood, the corpulent captain watched the small speck carefully with his glasses, then rubbed his fat hands with glee and expectation. The fool Englishman was falling beautifully into his little trap. Involuntarily he glanced over his shoulder, and there in a large clearing behind the wood, were ten great German battle-planes, all ready to go up at a moment’s notice and with pilots and observers standing by.

By this time the British machine had come considerably lower, and was well behind the wood, and into the German country. The captain gave a sharp, guttural order. Immediately the noise of ten great propellers smote the still air, and the squadron rose swiftly from the wood like a covey of wild ducks. The hated Englishman was hopelessly trapped.

And what of our man? Turning leisurely to make a last reconnaissance of the wood, he found ten great German battle-planes between himself and the lines. He cursed profusely at his own crass stupidity. He had been warned, and he had thought fit to ignore the warning, and this was the result. Anyway he would make a good fight for it. He fingered his machine-gun cautiously. Yes, everything was ready to hand. He set his teeth, opened his engine “full out” and began to climb rapidly.

The Germans also climbed, and within a very short space of time he found himself hemmed in on all sides, with lead flying at him from all points, and at all angles. Anyhow, he determined to have a good run for his life, and singling out two Germans immediately beneath him, he dived rapidly. As he did so, he was hit by shrapnel; for a short space of time he was unconscious, then again regaining control of his machine, began to use his machine-gun to good effect.
