And west they went.
It was about half an hour after this that Roger and Jimmy, driving the Bixtons before them, saw a group of American soldiers coming toward them over a shell-torn field.
"Home again!" cried Jimmy.
At the sight of Jimmy and Roger, with guns held in readiness, marching two other Americans soldiers ahead of them the party of Sammies, under the leadership of a sergeant, broke into a double quick, and soon reached the Khaki Boys.
"What's all this?" demanded the sergeant. "Who are you two with the guns, and what are these? Deserters?" he asked, pointing to the Bixtons.
"Worse than deserters! They're traitors!" said Jimmy. "And we left two German spies back in the cave. We've found out the secret of the smoke signals. We'd like to report to the officer commanding this sector, and deliver our prisoners."
"Smoke signals, eh?" exclaimed Sergeant Walton, who had charge of a party out in search of possibly forgotten wounded men. "That's queer. A squad of our boys, several squads, in fact, are out looking for two of the smoke signal machines which the signal corps reports missing since last night."
All eyes were turned toward the Bixtons. But they maintained their policy of silence.
"Come on, I'll take you to the K. O.," offered the sergeant.
This was done, and Roger and Jimmy soon turned over their prisoners and gave an account of the whole proceeding from the time they were knocked senseless until they attacked and caught the German spies. Then, after the boys had accurately described the location of the cave, a party was sent there to bring back the two Huns. The one had considerably improved, being but stunned, but the other never regained consciousness, and died that night.
