"They're making for our artillery!" exclaimed Sherburne with true instinct. "Follow me, men! We must hold them back, for a few minutes at least!"

Sherburne and his gallant troops were just in time. A great force of cavalry in blue suddenly appeared in the whitish and foggy dawn and charged straight for the guns. Without delaying a moment, Sherburne flung his troops in between, although they were outnumbered twenty to one or more. He did not expect to stop them; he merely hoped to delay them a few minutes, and therefore he offered himself as a sacrifice.

Harry was beside Sherburne as they galloped straight toward the Northern cavalry, firing their short carbines and then swinging their sabres.

"They'll ride over us!" he shouted to Sherburne.

"But we'll trouble 'em a little as they pass!" the captain shouted back.

Harry shut his teeth hard together. A shiver ran over him, and then his face grew hot. The pulses in his temples beat heavily. He was sure that Sherburne and he and all the rest were going to perish. The long and massive Northern line was coming on fast. They, too, had fired their carbines, and now thousands of sabres flashed through the mists. Harry was swinging his own sword, but as the great force bore down upon them, the white mist seemed to turn to red and the long line of horsemen fused into a solid mass, its front flashing with steel.

He became conscious, as the space between them closed rapidly, that a heavy crackling fire was bursting from a wood between the Northern cavalry and the river. The Southern skirmishers, brushed away at first, had returned swiftly, and now they were sending a rain of bullets upon the blue cavalrymen. Many saddles were emptied, but the line went on, and struck Sherburne's troop.

Harry saw a man lean from his horse and slash at him with a sabre. He had no sabre of his own, only a small sword, but he cut with all his might at the heavy blade instead of the man, and he felt, rather than saw, the two weapons shatter to pieces. Then his horse struck another, and, reeling in the saddle, he snatched out a pistol and began to fire at anything that looked like a human shape.

He heard all about him a terrible tumult of shots and shouts and the thunder of horses' hoofs. He still saw the red mist and a thousand sabres flashing through it, and he heard, too, the clash of steel on steel. The Northern line had been stopped one minute, two minutes, and maybe three. He was conscious afterwards that in some sort of confused way he was trying to measure the time. But he was always quite certain that it was not more than three minutes. Then the Northern cavalry passed over them.

Harry's horse was fairly knocked down by the impetus of the Northern charge, and the young rider was partly protected by his body from the hoofs that thundered over them. Horse and rider rose together. Harry found that the reins were still clenched in his hand. His horse was trembling all over from shock, and so was he, but neither was much harmed. Beyond him the great cavalry division was galloping on, and he gazed at it a moment or two in a kind of stupor. But he became conscious that the fire of the Southern skirmishers on its flank was growing heavier and that many horses without riders were running loose through the forest.
