But in the first firing that ensued Erwin's Lewis gun suddenly jammed. This was probably one result of his having to use the German-made ammunition tossed to him earlier by Blaine, when his own had been exhausted. He signaled to his partner:

"Gun jammed! Must cut for home — understand?"

"All right! Go up - up -"

A burst of flame from Blaine's machine, and the toppling down of the
nearest adversary was the first result of this new encounter.
Evidently that flag waving from Blaine's captured plane had fooled the
Boches again.

Down, down went the hostile machine, its pilot frantically but ineffectually trying to right himself.

Passing Erwin, the latter saw the Boche, evidently a mere lad, working at the controls as the plane dropped down like a dead leaf in the air.

"Poor fellow," sighed Orris, beginning to spiral upward. "What a deadly cruel thing war now is!"

Up, up he climbed, two of the enemy following, while Blaine was engaging another, the last. The final view Erwin had of his bunkie the two were engaged in a close duel, dipping, darting, flashing about each other. Now came interchanging machine gun fire, with both gradually following Erwin higher, higher, until the latter began to feel that the thin air of these upper regions was getting on his nerves. A glance at his own register showed eighteen thousand feet or thereabouts.

Still his adversaries climbed after him. Now and then a spurt of flame and a spatter of bullets indicated that his own plane was being more or less perforated. The lad became doubtful as to the wisdom of waiting longer for his comrade. Evidently Blaine would fight on as long as his ammunition lasted or until disabled himself. After all, two hostile planes dropped and the third one brought home with its occupant was not a bad conclusion for a night's bombing raid on the enemy trenches.

Here a sudden, fierce gust of wind from the north catching him unawares half tilted his machine and then as he righted it sent him scurrying at terrific speed southward. At the same time a black cloud, belching and flaming thunder and lightning, swept down on him with almost the force of a hurricane.
