The information he let slip was not very illuminating—a few truthful statements about machines, pilots, and aerodromes, and a great many obvious lies. But his opinions on our aviators and machines were interesting. Our pilots were splendid, but too reckless, he thought. As for the machines, the Bristol Fighter was the work of the devil, and to be avoided at all costs; the R.E.8 might safely be attacked unless it were well protected; the British single-seaters were good; but the German Flying Corps regarded the B.E. types as sehr komisch.

As Willi was well-behaved and occasionally informative, and as he had been a flying contemporary of mine on the Western front in 1916 and 1917, I took him for a sea-bathe before he went back to his cage, while taking the precaution to swim closely behind him.

Next day the heat was intense, so that I was glad indeed when the arrival of an A.E.G. from the north gave me the chance to climb to the cool levels of 8,000 to 10,000 feet, flying hatless and in shirt-sleeves. The trespassing two-seater spotted us, and retired before we could reach its height.

But the next turn of my flying partner and me, in the late afternoon, brought us the good fortune of sending a Hun bus to earth—from sheer fright and not out of control, unfortunately—in open country. I was well content on landing, for the atmosphere was cooler and almost pleasant, and my day's work should have been done.

But a pony, a monkey, and mischance conspired to send me beyond the lines for the third time that day, and the last time for many months. Instead of leaving the aerodrome at once I remained to play with Bohita, the marmoset mascot. Ten minutes later the bell clanged a warning. One of the waiting pilots raced to his machine, and was away; but the other, mounted on an energetic little pony, was chasing a polo ball. The pony, being jerked backward suddenly, reared up and threw its rider. Seeing that he must be hurt, or at any rate shaken, I climbed into his machine and sent word that I would replace him, so that no time should be wasted. It was then about one hour before sunset.

The first Nieuport had a good start, but the pilot was new to the game, and failed to see the white puffs from directional shots fired by the nearest A.A. battery. The last I saw of his bus was as it climbed due east, with the apparent intention of sniffing at a harmless R.E.8 to see if it were a Hun, and without noticing when I continually switch-backed my machine fore and aft, as a signal that a real Hun was near. I therefore left what should have been my companion craft to its own amusement, and climbed toward the British anti-aircraft bursts.

At about 9,000 feet I reached their level, and picked up the intruder—a gray-planed two-seater of the latest Rumpler type. When I was still some 800 yards distant its pilot swerved round, and, holding down his machine's nose for extra speed, raced back northward rather than be forced to fight. I streaked after it, beyond the trenches.

Now the Rumpler was faster than my Nieuport, but was slower on the climb. My only chance of catching up, therefore, was first to gain height and then to lose it again in a slanting dive, with engine on, in the direction of the Boche; and to repeat the tactics. Although each dive brought me a little closer, this method was a slow business. I remember passing Kilkilieh and seeing Shechem, and still being outside machine-gun range of the black-crossed bus ahead.

It was at a spot west of Shechem, and about twenty miles from the lines, that I got my chance. By then we had nosed down to 6,000 feet. Being able to manœuvre twice as quickly as the big two-seater, the little Nieuport was soon in a "blind-spot" position, and I could attack from a sideways direction, opening fire at 80 yards. The Rumpler dived almost vertically out of the way, and I overshot.

I was turning again, when from above came a succession of raps—tatatatatat, tatatat, tatatatatat—the unmistakable tap-tapping of aërial machine-gun fire. I looked up, and saw three scouts dropping toward me from a cloud-bank.
