Caught by the Turks

Half an hour before dawn on November the thirteenth, 1915. . . .
We were on an aerodrome by the River Tigris, below Baghdad, about to start out to cut the telegraph lines behind the Turkish position.
My pilot ran his engine to free the cylinders from the cold of night, while I stowed away in the body of the machine some necklaces of gun-cotton, some wire cutters, a rifle, Verey lights, provisions, and the specially prepared map—prepared for the eventuality of its falling into the hands of the Turks—on which nothing was traced except our intended route to the telegraph lines west and north of Baghdad. Some primers, which are the explosive charges designed to detonate the gun-cotton, I carefully stowed away in another part of the machine, and with even more care—trepidation, indeed—I put into my pockets the highly explosive pencils of fulminate of mercury, which detonate the primers which detonate the gun-cotton.
Then I climbed gingerly aboard, feeling rather highly charged with explosives and excitement.
For some time the pilot continued to run his engine and watch the revolution meter. The warmer the engine became, the colder I got, for the prelude to adventure is always a chilly business. Unlike the engine, I did not warm to my work during those waiting moments. At last, however, the pilot waved his hand to give the signal to stand clear, and we slid away on the flight that was to be our last for many a day. The exhaust gases of our engine lit the darkness behind me with a ring of fire. I looked back as we taxied down the aerodrome, and saw the mechanics melting away to their morning tea. Only one figure remained, a young pilot in a black and yellow fur coat, who had left his warm bed to wish us luck. For a moment I saw him standing there, framed in flame, looking after us regretfully. Then I saw him no more, and later they told me (but it was not true) that he had died at Ctesiphon.
We rose over the tents of our camp at Aziziah, all silver and still in the half-light, and headed for the Turkish outposts at El Kutunieh. Their bivouac fires mounted straight to heaven. It was a calm and cloudless dawn, ideal weather for the business we had been sent out to do.
