Mingled with the many black bursts were a few green ones, probably gas shells, for Archie had begun to experiment with the gas habit. Very suddenly a line of fiery rectangles shot up and curved towards us when they had reached three-quarters of their maximum height. They rose and fell within thirty yards of our tail. These were "onions," the flaming rockets which the Boche keeps for any hostile aircraft that can be lured to a height between 4000 and 6000 feet. I yelled to V., my pilot, that we should have to dodge. We side-slipped and swerved to the left. A minute later the stream of onions had disappeared, greatly to my relief, for the prospect of a fire in the air inspires in me a mortal funk. Soon we were to pass from the unpleasant possibility to the far more unpleasant reality. Once outside the unhealthy region, we climbed to a less dangerous height. Again we became the target for a few dozen H.E. shells. We broke away and swooped downward. Some little distance ahead, and not far below, was a group of five Albatross two-seaters. V. pointed our machine at them, in the wake of the flight-commander's bus. Next instant the fuselage shivered. I looked along the inside of it and found that a burning shell fragment was lodged on a longeron, half-way between my cockpit and the tail-plane. A little flame zigzagged over the fabric, all but died away, but, being fanned by the wind as we lost height, recovered and licked its way toward the tail. I was too far away to reach the flame with my hands, and the fire extinguisher was by the pilot's seat. I called for it into the speaking-tube. The pilot made no move. Once more I shouted. Again no answer. V.'s earpiece had slipped from under his cap. A thrill of acute fear passed through me as I stood up, forced my arm through the rush of wind, and grabbed V.'s shoulder. "Fuselage burning! Pass the fire extinguisher!" I yelled. My words were drowned in the engine's roar; and the pilot, intent on getting near the Boches, thought I had asked which one we were to attack. "Look out for those two Huns on the left," he called over his shoulder. "Pass the fire extinguisher!" "Get ready to shoot, blast you!" "Fire extinguisher, you ruddy fool!"
