"Good luck!" exclaimed the boys as the major turned on his heel and
strode rapidly away.

The two lads returned to their own quarters and gave themselves up to
rest. So completely were they worn out that it was dark when they again
opened their eyes; and they probably would not have done so then had not
the clear notes of a bugle awakened them.

Rushing into the open, the lads saw that on all sides the troops were
ready to move--whether forward or backward they could not tell as yet. It
was evident, however, that something was afoot.

Hal and Chester made their way to the side of General French and joined
the members of his staff. The gallant British commander was sitting his
horse quietly, his staff grouped about him. Occasionally one went dashing
away with some order, as the general gave a laconic command.

The boys had hardly taken their places when General French said quietly:

"Order a general advance!"

A moment later and the small though mighty host of Britain was in motion,
and a loud cheer rang out on the still night air as the troops perceived
that they were going forward--that the retreat had ended.

Swiftly and silently the army advanced. Ahead could be heard the crack,
crack of rifle fire, indicating that the outposts were engaged with the
enemy. Also, from the distance, could be heard the booming of the great
German guns, and as the English advanced still further men began to fall
before the deadly German artillery fire.
