But first he had another job to do, and he lifted his gaze and peered at the smoke and flame filled sky ahead. Besides smoke and flame there were countless numbers of planes streaking and darting around in all directions. The air was practically filled with them. There was layer after layer of planes reaching from low down over the battle grounds right up to the sun. And insofar as he could tell at the distance not a single one of them was of Allied design. They were all German.
At that moment Freddy pounded on his shoulder for the third time. And the voice that screamed in his ear rang with fright and alarm.
"More speed, Dave! Look behind us. There's a plane, a Messerschmitt. I think it's chasing us. They might even try to shoot us down. What'll we do, Dave?"
"What'll we do?" Dave echoed and glanced back at the sleek needle shaped plane with its low monoplane wing. "We'll keep on going. They may not try to shoot at us. Once we get on the other side of the Canal, we'll be safe. We'll go down and land."
But even as Dave spoke the words to give good cheer to Freddy his own heart was pounding with fear. The other plane was drawing up on them as an express train overtakes a slow freight. He could see now that it was a Messerschmitt One-Ten. A moment later he saw the gunner-observer in the rear pit shove back his bullet proof glass cockpit hatch and stand up and wave signals with both his arms. Those signals plainly said for them to go down and land at once, but Dave pretended that he hadn't seen. He rammed the palm of his free hand hard against the already wide open throttle, as though if in so doing he might get increased speed out of the plane.
It was no more than a futile gesture, however. In the matter of seconds the Messerschmitt had pulled right up along side them. Dave turned and looked across the air space that separated the two planes. His heart zoomed up his throat so fast it almost bumped up against his back teeth. The German observer was still sending signals to land, but not with his arms and hands, now. He was doing it with the aerial machine gun fixed to the swivel mounting that circled the rim of his cockpit. He was pointing the gun at them and then tilting it down toward the ground as he nodded his helmeted head vigorously.
Dave stared at the gun as though hypnotized. The blood pounded in his temples, and his whole body was on fire one instant and icy cold the next. There was death staring straight at him, and he could hardly force his brain to think. He knew he couldn't just keep on flying. He had to do something or the German would open fire and turn their plane into a blazing inferno. On the other hand, his fighting heart refused to surrender and go back and face the ugly wrath of that Colonel Stohl. For this Messerschmitt had unquestionably been sent out after them at the Colonel's orders. Who knew? Perhaps Colonel Stohl had been the German he had seen climb out of the observer's pit of this very Arado he was now trying to fly to safety behind the Belgian lines. It would have been very easy for the German to phone the nearest air field and have a plane sent out after them.
Tac-a-tac-a-tac-a-tac!
Jetting tongues of flame leaped out from the muzzle of the machine gun in the other plane. The savage yammer sound smashed against Dave's ears even as he saw the wavy trails of tracer smoke cut across in front of the nose of his plane. The yammer of the gun snapped him into action and sent his eyes darting to the cowled nose of the Arado. His heart seemed to cry out when he saw that the plane carried no guns. On impulse he twisted his head around to Freddy's pit, but there, too, disappointment mocked him. The plane was not armed! It was probably just a courier plane used far behind the lines on safe missions only.
As he looked into Freddy's eyes he saw reflected there his own bitter thoughts. They were completely at the mercy of that Messerschmitt flying along wing to wing with them. Unskilled and untrained though they were in aerial combat, it was heartrending not to be able to put up some kind of a battle for their lives.
