He sighted, before and below, a road where German guns were being rushed forward; dove down upon them, leading his flight again and bombed the guns, machine-gunned the artillerymen; he bombed a supply train of motor lorries; he flew over and machine-gunned two motor cars with German officers and saw one of the cars overturn. But German combat pilots were appearing in force all about; Gerry gazed up and saw a big, black-crossed two-seater accompanied by two single-seaters maneuvering to dive down upon him. He swerved off, therefore, and fled. For a moment he longed for his swift-darting little Spad instead of this heavier ship which bore bombs in addition to machine guns. But the Spads of his comrades and English combat machines appeared; and the German pilots above did not dare to dive. They circled, awaiting reinforcement which swiftly came--triplane Fokkers mostly, Gerry thought. As he watched them, he forgot all about the ground; for the French and the English pilots, ten thousand feet above him, were starting an attack. He circled and climbed a few thousand feet; he knew that with his heavy raiding machine, he could not join that battle. But heavy German airplanes--for observation, for photographic work, or to guide the advancing German guns--were appearing in the lower levels and slipping forward under the protection of the Fokkers and the Albatrosses. Gerry went for one of these and turned it back; he went for another--a two-seater--and he saw the German machine gunner fall forward; he saw the pilot’s hooded head drop; he saw flame flash from the gasoline tank; the two-seater tumbled and went down. He dared not follow it with his eyes even for the short seconds of its fall; machines from the battle above were coming down where he was. A Fokker dropped, turning over and over to escape a Spad which came down on its tail and got it anyway; now a Spad streaked past in flame. A two-seater--a German machine marked by the big black crosses under its wings--glided slowly down in a volplane. Gerry circled up to it, approaching from the side with the lanyard of his machine guns ready; but the German pilot raised an arm to signal helplessness. His gunner was dead across his guns; his engine was gone; he had kept control enough only to glide; and he was gliding, Gerry saw, with the sun on his right. That meant he was making for German-held ground. He came beside the gliding two-seater, therefore, and signaled to the west. The German obeyed and, while Gerry followed, he glided to the field in the west and landed. Gerry came down beside him and took the pilot prisoner; together they lifted the body of the German observer from his seat and laid him on the ground. Gerry possessed himself of the German’s maps and papers.
