they surmised with good reason that an attack was
threatened and they were eager to meet it.

Dick and Warner were near the head of the line on the right of the
tracks, and Sergeant Whitley was with them. The train began to puff
heavily, and in spite of every precaution some sparks flew from the
smoke-stack. Dick knew that it was bound to rumble and rattle when it
started, but he was surprised at the enormous amount of noise it made,
when the wheels really began to turn. It seemed to him that in the
silence of the night it could be heard three or four miles. Then he
realized that it was merely his own excitement and extreme tension of
both mind and body. Canby was taking the train forward so gently that
its sounds were drowned two hundred yards away in the swirl of wind and
rain.

The men marched, each line keeping abreast of the train, but fifty yards
or more to one side. The young troops were forbidden to speak and their
footsteps made no noise in the wet grass and low bushes. Dick and Warner
kept their eyes on the mountains, turning them alternately from north to
south. Nothing appeared on either ridge, and no sound came to tell of an
enemy near.

Dick began to believe that they would pass through the valley and out of
the trap without a combat. But while a train may go two or three miles
in a few minutes it takes troops marching in the darkness over uncertain
ground a long time to cover the same distance. They marched a full half
hour and then Dick suppressed a cry. The light, burning as intensely
red as before, appeared again on the mountain to the right, but further
toward the west, seeming to have moved parallel to the Northern troops.
As Dick looked it began to flash swiftly from side to side and that
chill and weird feeling again ran down his spine. He looked toward the
south and there was the second signal, red and intense, replying to the
first.

Dick heard a deep "Ah!" run along the line of young troops, and he knew
now that they understood as much as he or any of the officers did. He
now knew, too, that they would not pass out of the valley without a
combat. The Southern forces, beyond a doubt, would try to shut them in
at the western mouth of the valley, and a battle in the night and rain
was sure to follow.

The train continued to move slowly forward. Had Colonel Newcomb dared
he would have ordered Canby to increase his speed in order that he might
reach the western mouth of the valley before the S
