The chances were a thousand to one against the prophecy, but it all came true, just as they wished.

The rain increased a little, although it was not yet able to penetrate Dick's heavy coat, but they were compelled to go more slowly on account of the thickening darkness. They reached very soon the crest of the pass and halted there a little while to see or hear any sign of a human being. But no sound came to them and they resumed the scout in the darkness, riding now down the slope which would end before long in a great valley.

The ground softened by the rain deadened the footsteps of their horses, and they made little noise as they rode down the narrow pass, examining as well as they could the dripping forest on either side of the road. Shepard was a bit ahead, and Dick and the sergeant, riding side by side, came next. Behind were the troopers, a small picked band, daring horsemen, used to every kind of danger.

They did not really anticipate the presence of an enemy in the pass. They knew that Colonel Talbot's command had turned toward the southwest. All the other Confederate forces must be gathering far up the valley to meet Sheridan, and the South was too much reduced to raise new men. Yet after a half hour's moderate riding down the slope Dick became sure that some one was in the narrow belt of forest on their right, where the slope was less steep than on their left.

At first it seemed to be an intuition, merely a feeling brought on waves of air that men, enemies, were in the wood. Then he knew that the feeling was due to sounds as of someone moving lightly through a wet thicket, but unable to keep the boughs from giving forth a rustle. He was about to call to Shepard, but before he could do so the spy stopped. Then all the others stopped also.

"Did you hear it?" Dick whispered to Sergeant Whitley.

"Yes," replied the sergeant. "Men are moving in the thicket on our right. I couldn't hear much, but they must be as numerous as we are. They're enemies or they'd have come out. They're on foot, too, as they couldn't manage horses in those deep woods. Likely they've left their mounts with a guard on top of a ridge, as men on foot wouldn't be abroad at such a time on such a night."

"Then it's an ambush!" said Dick, and he added in a sharp voice:

"Pull away to the left, men, under cover!"

Shepard was the first to turn and all the others followed instantly. Three jumps of the horses and they were among the bushes and trees on the left. It was lucky for them that they had heard the sound of the wet bushes rustling together, as a dozen rifles flashed in the dusk on the other side of the road. Bullets cut the leaves about them. Two or three buried themselves with a plunk in the trunks of trees, one killed a horse, the trooper springing clear without hurt, and one man was wounded slightly in the arm.
