There was no denying this. A balloon bonfire was the only possible conclusion to the adventure, and we both failed at lighting it. I, too, redressed when very close to the bag, and made a steep bank in order to escape the burst of flame from the ignited gas. The rockets leaped out, with a fine, blood-stirring roar. The mere sound ought to have been enough to make any balloon collapse. But when I turned, there it was, intact, a super-Brobdingnagian pumpkin, seen at close view, and still ripe, still ready for plucking. If I live to one hundred years, I shall never have a greater surprise or a more bitter disappointment.
There was no leisure for brooding over it then. My altimeter registered only two hundred and fifty metres, and the French lines were far distant. If the motor failed I should have to land in German territory. Any fate but that. Nevertheless, I felt in the pocket of my combination, to be sure that my box of matches was safely in place. We were cautioned always to carry them where they could be quickly got at in case of a forced landing in enemy country. An airman must destroy his machine in such an event. But my Spad did not mean to end its career so ingloriously. The motor ran beautifully, hitting on every cylinder. We climbed from two hundred and fifty metres to three hundred and fifty, four hundred and fifty, and on steadily upward. In the vicinity of the balloon, machine-gun fire from the ground had been fairly heavy; but I was soon out of range, and saw the tracer bullets, like swarms of blue bubbles, curving downward again at the end of their trajectory.
No machines, either French or German, were in sight. Irving had disappeared some time before we reached the balloon. I had not seen Drew from the moment when he fired his rockets. He waited until he made sure that I was following, then started for the west side of the salient. I did not see him, because of my interest in those clouds of blue bubbles which were rising with anything but bubble-like tranquillity. When I was clear of them, I set my course westward and parallel with the enemy lines to the south.
I had never flown so low, so far in German territory. The temptation to forget precaution and to make a leisurely survey of the ground beneath was hard to resist. It was not wholly resisted, in fact. Anti-aircraft fire was again feeble and badly ranged. The shells burst far behind and above, for I was much too low to offer an easy target. This gave me a dangerous sense of safety, and so I tipped up on one side, then on the other, examining the roads, searching the ruins of villages, the trenches, the shell-marked ground. I saw no living thing; brute or human; nothing but endless, inconceivable desolation.
