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 Southern force had a chance to tear up the rails, but there was no use for the train without the troops and they were already marching as fast as they could.
The gorge was now not more than a quarter of a mile away. Dick was able to discern it, because the darkness there was not quite so dark as that which lay against the mountains on either side. He was hopeful that they might yet reach it before the Southern force could close down upon them, but before they went many yards further he heard the beat of horses’ feet both to right and left and knew that the enemy was at hand.
“Take the train on through the pass, Canby!” shouted Colonel Newcomb. “We’ll cover its retreat, and join you later-if we can.”
The train began to rattle and roar, and its speed increased. Showers of sparks shot from the funnels of the two engines, and gleamed for an instant in the darkness. The beat of horses’ feet grew to thunder. Colonel Newcomb with great presence of mind drew the two parallel lines of his men close together, and ordered them to lie down on either side of the railroad track and face outward with cocked rifles. Dick, the Vermonter, and Sergeant Whitley lay close together, and the three faced the north.
“See the torches!” said Whitley.
Dick saw eight or ten torches wavering and flickering at a height of seven or eight feet above the ground, and he knew that they were carried by horsemen, but he could not see either men or horses beneath. Then the rapid beat of hoofs ceased abruptly at a distance that Dick thought must be about two hundred yards.
