As they talked, twilight came, and the road led once more through the deep woods, where the shade turned the twilight into the darkness of night. Then rifles flashed suddenly in the thickets, and a half-dozen horsemen fell. The whole column was thrown for an instant or two into disorder, frightened horses rearing and stamping, and, before their riders could regain control, another volley came, emptying a half-dozen saddles.
Colonel Hertford gave rapid commands. Then, shouting and waving his saber he galloped boldly into the forest, reckless of trees and bushes, and Dick, the sergeant, and the whole troop followed. The lad was nearly swept from his horse by a bough, but he recovered himself in time to see the figures of men on foot fleeing rapidly through the dusk.
Bullets pattered on bark and leaves, and the angry horsemen, after discharging their carbines, swept forward with circling sabers. But the irregulars who had ambushed them, save a few fallen before the bullets, escaped easily in the dense woods, and under cover of the darkness which was now coming down, thick and fast.
A trumpet sounded the recall and the cavalrymen, sore and angry, drew back into the road. They had lost a dozen good men, but Colonel Hertford felt that they could not delay for vengeance. Grant's orders were to come at once; and he intended to obey them.
“I'd wager a year's pay against a Confederate five-dollar note,” said Sergeant Whitley to Dick, “that the man who laid that ambush was Slade. He'll keep watch on us all the way to Grant, and he'll tell the Southern leaders everything the general is doing. Oh, he's a good scout and spy.”
“He's proved it,” said Dick, “and I'd like to get a fair shot at him.”
They rode nearly all night and most of the next day, and, in the afternoon, they met other men in blue who told them that a heavy Union force was advancing. They had no doubt now that Grant's great plan was already working and in a short time they reached McPherson, advancing with Logan's division. Hertford reported at once to McPherson, who was glad enough to have his cavalry, and who warmly praised Dick and the sergeant for the dangerous service they had done so well. As it would have been unwise for them to attempt to reach Grant then he kept them with him in the march on Jackson.
