His foot touched something hard which brought him to the realization that he must lessen the force of his advance or perhaps have his life dashed out upon a rocky shore; and presently he was staggering forward, brushing his hair away from his eyes, wondering where he was, and scarcely sensible of anything--his head throbbing, his whole body on the verge of exhaustion. "It's my fault--anyway--I got to admit it----" he thought, "and--it serves--me--right." One firm resolution came to him. Now that Providence had seen fit to cast him ashore, if he was to be permitted to continue his flight alone, he would go straight for his goal, the Swiss border, and not be led astray (that is what he called it, _led astray_) by any other enterprise. His duty as a soldier, and he thought of himself as a soldier now, was clear. His business was to help Uncle Sam win the war and he must leave it to Uncle Sam to put an end to the stealing of young girls and to restore them to their homes. He saw himself now, as Archer had depicted him, in the silly role of a "story book hero" and he felt ashamed. He knew that General Pershing would not have sent him rescuing girls, and that the best way he could help France, and even the Leteurs, was to hurry up and get into the trenches where he belonged. Yes, Archer was right. And with a pang of remorse Tom remembered how Archer had said it, "rescuing a girrl!" He would never hear Archer talk like that any more.... He had more than once been close enough to death to learn to keep his nerve in the presence of it, but the loss of his companion quite unnerved him. It had not occurred to him that anything _could_ happen to Archer, who claimed himself that he always landed right side up because he was lucky. Tom could not realize that he was gone. Still, comrades were lost to each other every day in that far-flung trench line and in that bloody sea of northern France friends were parted and many went down. "_Down_----" How that awful word had sounded--long drawn out and faint in the storm and darkness! He stumbled over a rocky space and ran plunk into something solid. As he looked up he could distinguish the top of it; uneven and ragged it seemed against the blackness of the night. Whatever it was, it seemed to be slender and rather high, and the odd thought came to him that he was on the deck of some mammoth submarine, looking up at the huge conning tower. Perhaps it was because he _had_ once been rescued by a submarine, or perhaps just because his wits were uncertain and his nerves unstrung, but it was fully a minute before he realized that he was on solid earth--or rock. It afforded him a measure of relief.
