Though the Archies were now quite out of range, night was so near at hand that this seemed good policy. Blaine now added: "I'm goin' to give that Fokker another round. Be back with you in a minute." Then on he went after the German. What ensued was rather puzzling to both Bangs and Erwin. Blaine was now evidently faster than the German, whose machine had apparently sustained some internal injury. They saw the biplane close in on the Hun amid a rapid fire of bullets from each at the other. All at once the Hun began sidling irregularly towards the earth. By this time both the others, having risen somewhat, caught glimpses through their field glasses of a number of nearing planes winging from the west. Below, as far as could be seen, stretched No-Man's-Land. Behind was a growing blackness that denoted approaching night. To both Bangs' and Erwin's astonishment, the biplane, instead of returning, was pointing downward after the crippled Fokker. Then from the north whirled a sea-fog that presently enveloped all, obliterating what remained of light, hiding even Blaine and the adversary he had pursued. It was strange, mysterious. Erwin, who was lower than the others, here saw the crumbling walls and towers of what had once been an old baronial chateau. Near this the biplane had landed. No sign just then of the Fokker, though that must have descended also, for the machine or the man in it was undoubtedly injured. Erwin grabbed his megaphone, shouting up at Buck hovering near, "I'm going down. Blaine's already landed. Come on!" But for some reason Bangs declined. Being higher up, he had detected signs of those other planes invisible to those below. "Go on down," he shouted. "I want to do a little scouting." And off he flew, determined all at once to find out who and what might be approaching. But his purpose was defeated by the onrush of the fog, that thickened still more, while those landed below were equally invisible to Buck. However having a general idea as to the direction best for him to take, he turned that way after recklessly feeling out in vain for further sight of the approaching squadron. Here we will leave him for the present. When Erwin at last brought his plane down beside the half ruined chateau, he found both Stanley and Blaine stooping over a prostrate form soon identified as that of the German aviator. Near by was the Fokker, somewhat disabled, but not in such bad condition. The man himself had just expired.
