"By Jove! I hope nothing happens to Hal," he muttered.
It seemed to Chester that the next hour would never pass, but at last the hands of his watch showed 10 o'clock.
"Time to be moving," the lad told himself.
He produced his pair of revolvers and examined them carefully.
"All fine and dandy," he muttered. "Well, I guess there is no reason for waiting longer."
He turned and strode off in the direction Hal had gone just a short hour before.
CHAPTER XII
HAL MEETS AN OBSTACLE
Hal made rapid progress through the American lines. It was almost an hour after he left Chester that he reached the most advanced American outposts toward the north. He was challenged there, but after confiding to the officer in charge of operations there that he was on a mission for General Rhodes, he was allowed to pass.
The German lines, Hal learned, were perhaps two hundred yards ahead. There the enemy had hurriedly dug a temporary line of shallow trenches and settled down to hold them. It was Hal's business to get into and to pass through them.
