"Let's get out of here," he cried. "It's getting too warm."
Together the lads dashed toward the trench.
A cry of alarm went up from the Germans behind.
"Shoot them!" cried a voice that Hal recognized as that of the German colonel.
"Zig-zag, Chester!" cried Hal, and suited the action to the word.
Chester followed his chum's example and the first volley from behind failed to find a mark.
By this time the lads were at the edge of the trench.
"Up and over with you, quick!" cried Chester.
Hal leaped to the top of the trench and toppled to the ground beyond even as half a score of bullets sang across the spot where his head had been a moment before.
Chester also sprang for the top of the trench. But he had leaped too soon, and instead of reaching the top he fell short, and dropped down inside the trench again.
