That dispatch said, "Come, I need you urgently here," and the "here" in question, was Gettysburg, at least twenty miles distant. Now, with worn-out men and horses, twenty miles was a serious matter. Stuart's brows were knit, and he mused gloomily.

Suddenly he turned and addressed me.

"You were right, Surry," he said, "those guns were at Gettysburg. This dispatch, sent this morning, reports the enemy near there."

I bowed; Stuart reflected for some moments without speaking. Then he suddenly said:--

"I wish you would go to General Lee, and say I am coming, Surry. How is your horse?"

"Worn-out, general, but I can get another."

"Good; tell General Lee that I will move at once to Gettysburg, with all my force, and as rapidly as possible!"

"I will lose no time, general."

And saluting, I went out.

From the captured horses I selected the best one I could find, and burying the spurs in his sides, set out through the black night.

XX.

THE HOUSE BETWEEN CARLISLE AND GETTYSBURG.

You know when you set out, the proverb says, but you know not when you will arrive.

I left Carlisle, breasting the night, on the road to Gettysburg, little thinking that a curious incident was to occur to me upon the way--an incident closely connected with the destinies of some personages who play prominent parts in this history.

I had ridden on for more than an hour, through the darkness, keeping a good look-out for the enemy, whose scouting parties of cavalry were known to be prowling around, when all at once, my horse, who was going at full speed, struck his foot against a sharp point of rock, cropping out from the surface.

The animal stumbled, recovered himself, and went on as rapidly as before. A hundred yards further his speed relaxed; then he began to limp painfully; then in spite of every application of the spur I could not force him out of a slow limping trot.

It was truly unfortunate. I was the bearer of an important message, and was surrounded by enemies. The only chance was to pa.s.s through them, under shadow of the darkness; with light they would perceive me, and my capture be certain.

A hundred yards further, and I found I must decide at once upon the course to pursue. My horse seemed about to fall. At every stroke of the spur he groaned piteously, and his limp had become a stagger.

I looked around through the trees, and at the distance of a quarter of a mile I saw the glimmer of a light. To obtain another horse was indispensable under the circ.u.mstances; and looking to see that my revolver was loaded and capped, I forced my tottering animal toward the mansion in which the light glimmered.

My design was simply to proceed thither, "impress" a fresh horse at the pistol's muzzle; throw my saddle upon him; leave my own animal, and proceed on my way.

Pushing across the fields, and dismounting to let down the fences which my limping animal could not leap, I soon approached the light. It shone through the window of a house of some size, with ornamental grounds around it, and apparently the abode of a man of means.

At fifty paces from it I dismounted and tethered my horse in the shadow of some trees. A brief reconnaissance under the circ.u.mstances was advisable; and approaching the mansion silently, without allowing my sabre to make any clatter, I gained the long portico in front, and went to a window reaching down to the flooring of the verandah.

Through the half-closed venetians I could see into a large apartment, half library, half sitting-room, as the easy chairs, mantel ornaments, desks, and book-cases showed. On the centre-table burned a brilliant lamp--and by its light I witnessed a spectacle which made me draw back in the shadow of the shutter, and rivet my eyes on the interior.

Before me, in the illuminated apartment, I saw the woman whom Mohun had captured on the Rappahannock; and beside her the personage with whom she had escaped that morning in the wagon from Culpeper Court-House. I could not mistake him. The large, prominent nose, the cunning eyes, the double chin, the fat person, and the chubby hands covered with pinchbeck rings, were still fresh in my memory.

The name of this personage had been revealed by Nighthawk. Swartz, the secret agent, blockade-runner, and "best spy in the Federal army" was before me.

A glance at the woman revealed no change in her appearance. Before me was the same lithe and graceful figure, clad as before in a gray dress.

I saw the same snow-white cheeks, red lips, and large eyes burning with a latent fire.

The two were busily engaged, and it was not difficult to understand their occupation. The desks, drawers and chests of the apartment were all open; and the female with rapid hands was transferring papers from them to Swartz, who methodically packed them in a leathern valise.

These papers were no doubt important, and the aim to remove them to some place of safety beyond the reach of the Confederates.

I gazed for some moments, without moving, upon the spectacle of these two night-birds at their work. The countenance of the lady was animated; her motions rapid; and from time to time she stopped to listen. Swartz, on the contrary, was the incarnation of phlegmatic coolness. His face wore an expression of entire equanimity; and he seemed to indulge no fears whatever of intruders.

All at once, however, I saw his eyes glitter as they fell upon a paper which she handed him to pack away with the rest. It was carefully folded, but one of the folds flew open as he received it, and his eyes were suddenly fixed intently upon the sheet.

Then his head turned quickly, and he looked at his companion. She was bending over a drawer, and did not observe that glance. Thereupon Swartz folded up the paper, quietly put it in his pocket, and went on packing the valise with his former coolness; only a slight color in his face seemed to indicate concealed emotion.

As he pocketed the paper, his companion turned round. It was plain that she had not perceived the manoeuvre.

At the same moment I heard the sound of hoofs in rear of the house, and the clatter of a sabre as a cavalier dismounted. A few indistinct words, apparently addressed to a servant or orderly, followed. Then the door of the apartment opposite the front window was thrown open, and a man entered.

In the new-comer I recognized Mohun's adversary at Upperville--Colonel Darke, of the United States Cavalry.

XXI.

FALLEN.

Darke entered the apartment abruptly, but his appearance seemed to occasion no surprise. The spy retained his coolness. The lady went on with her work. You would have said that they had expected the officer, and recognized his step.

Their greeting was brief. Darke nodded in apparent approbation of the task in which the man and woman were engaged, and folding his arms in front of the marble mantel, looked on in silence.

I gazed at him with interest, and more carefully than I had been able to do during the fight at Upperville, when the smoke soon concealed him. Let me draw his outline. Of all the human beings whom I encountered in the war, this one's character and career were perhaps the most remarkable. Were I writing a romance, I should be tempted to call him the real hero of this volume.

He was a man approaching middle age; low in stature, but broad, muscular, and powerful. He was clad in the full-dress uniform of a colonel of the United States Cavalry, wore boots reaching to the knee and decorated with large spurs; and his arms were an immense sabre and a brace of revolvers in black leather holsters attached to his belt.

His face was swarthy, swollen by excess in drink apparently, and half covered by a s.h.a.ggy beard and mustache as black as night. The eyes were deep-set, and wary: the poise of the head upon the shoulders, haughty; the expression of the entire countenance cold, phlegmatic, grim.

Such was this man, upon the surface. But there was something more about him which irresistibly attracted attention, and aroused speculation. At the first glance, you set him down as a common-place ruffian, the prey of every brutal pa.s.sion. At the second glance, you began to doubt whether he was a mere vulgar adventurer--you could see, at least, that this man was not of low birth. There was in his bearing an indefinable something which indicated that he had "seen better days." The surface of the fabric was foul and defiled, but the texture beneath was of velvet, not "hodden gray."

"That brute," I thought, "was once a gentleman, and crime or drink has destroyed him!"

Darke continued to gaze at Swartz and the gray woman as they plied their busy work; and once or twice be pointed to drawers which they had failed to open. These directions were promptly obeyed, and the work went on. The few words which the parties uttered came in an indistinct murmur only through the window at which I was stationed.

Such was the scene within the mansion, upon which I gazed with strong curiosity: suddenly the neigh of a horse was heard in a clump of woods beyond the front gate; and Darke quickly raised his head, and then came out to the portico.
