The moon was throwing black shadows into the deep cleft in the San Saba, where the Crockett trail twisted along beside the swift-running rivulet, that rose in the heart of the hills and bubbled merrily away until lost in the westward valley and the brook that found its source at the springs far out under the foot-hills towards the Bravo. Slowly, wearily, warily, half a dozen troopers on jaded horses were feeling their way up the pass, a veteran corporal full thirty yards ahead of his fellows leading on. With the advance rode an officer whose shoulder-straps, gleaming on the shell jacket sometimes worn in the mounted service immediately after the war, seemed almost too bright and new to accord with the dust-grimed chevrons and trimmings of his comrades. New and brilliant, too, were the hilt and scabbard of the sabre that dangled by his side. New and "green" the men of his command had believed him to be, in cavalry matters at least, when first he joined them some weeks before, but the most casehardened old customer among their seasoned troopers had abandoned that view before ever they started on this scout after a gang of notorious outlaws, and now a new and very different theory was grinding its way into their tired brains,—that the "Doughboy Dragoon," as they had earlier dubbed him, "Captain Gallyhad," as one of them heard he was called, could give them points in covering the front of a column that were worth knowing, even if they had been learned in a doughboy regiment and among the Sioux. It would be a smart "Friday" that managed to ambuscade old Brooks's column that cloudless, moonlit, breezeless night, for, with that veteran's full consent, as well as to his infinite relief, Captain Barclay had himself gone forward with the advance the moment they began to wind in among the hills, and there at the post of danger he had held his way, alert and vigilant, despite long hours in saddle that had told heavily on more than half the command, calm and brave despite the fact that their welcome to the westward portal of the Pass was the sight of poor Blarney running to them for shelter, sympathy, and companionship, covered with the blood of his beloved rider.

And what was that rider's fate? It was now almost eleven o'clock, and no man knew. Only briefly had they halted and flocked about the panting steed, for stern was the need that held them to their course. With awe-stricken faces and compressed lips they looked into each other's eyes, as though to ask, What next? Who next? The major, tender-hearted as a woman, well-nigh choked with distress and anxiety as he turned to Barclay for counsel; and long before the rearmost of the column had reached the spot the decision had been made. The leaders were again pushing on. Young Brayton, with half a dozen troopers, had been despatched southwestward along the falda, ordered to search high and low for Lawrence, dead or alive. There was only one theory,—that, pushing eagerly ahead to the relief of Cramer's crippled troop, the gallant ex-captain had taken no thought of personal danger; the old instinct of leadership had possessed him, and, foremost of his little squad, he had been picked off by lurking bushwackers of the outlaws, crouching like Indians in the shelter of the rocks, and had fallen another victim of their desperado efforts. "One more fight in Texas," indeed. Poor, brave, warm-hearted Ned! That one more fight, reported in Washington by an indulgent department commander, might bring about immediate measures for his restoration to the army; but was it worth the risk? Was it worth what might befall those motherless children, praying for father hour after hour that livelong day? Should it have been permitted, had there been any one to prevent, in view of the fact that no longer was there soldier duty to lead him on? The government had released him from all that, had bidden him go. It had no further use for the services of such as he; it had turned him loose upon the world, with heavy stoppages against the stipulated bonus. "Oh, what right had he," cried Brooks, "to forget those babies back at Worth, well knowing as he must that no man's life is worth a hair in front of the rifles of that outlaw gang, much less an enemy such as Lawrence has shown himself to be?" The major's heart and head were heavy as once more the order forward was given. With every inclination to turn from his course with his entire command, to hasten in search of Lawrence's little party and Cramer's halted men, he well knew that should the paymaster and his precious thousands fall into the outlaw hands of the Friday gang he would be held responsible, even though San Saba's cantonment sent with him a force of forty men.

Once within the jaws of the Pass, the little detachment had closed on the head of column, the advance guard, Barclay's leading section, riding on and dispersing itself under his instructions, while Brooks held the other sections until Winn's men were all closed up, bringing with them the little squads that had scouted towards the short cut of the San Saba and had found no living soul in sight, yet had followed fresh hoof-tracks coming their way for miles. Whoever they were, the scouts of the gang were well ahead; whoever he was, "Friday" by this time knew the troops were coming. Then, with the flankers scouring the slopes well out to right and left wherever possible, Brooks's main body too had entered the winding defile and was lost in the bowels of the earth.

At eleven o'clock a watcher, gazing back into the broad shallow depression in which lay Crockett's, and then northward to the low-lying hills along the trail to Worth, could have seen no gleam of light far or near that would speak of human habitation or life or movement, no sign, in fact, of life of any kind; yet no sooner was the last shadowy form of horse and trooper swallowed up in the black gloom of the defile, no sooner had the last faint click of iron-shod hoofs died away in the hidden distance, than there slowly rose from behind the shelter of a clump of rocks, far out to the right of the trail, a crouching figure that went almost on all-fours to the edge of the rivulet, slunk away down the bank, dodging swiftly, softly, from boulder to boulder, until it disappeared around a little shoulder of bluff five hundred yards away, was lost to view a moment, then reissued into the moonlight, this time in saddle, swinging, cowboy fashion, a riata about its head as it rode. Spinning up the slopes and out of the stream-bed, away it went, careering up the billowy rise to the south, and was presently lost to view a second time behind some castellated rocks along the crest. Three minutes more, and these began to glow along their eastward face with the light of some unseen fire that flared for perhaps a minute somewhere about the hidden base of the group, and then, far away to the southeast, far out among the buttes and knolls in the heart of the range, there was a sudden flash of brilliant light, just as though some one had touched off in front of a reflector a pound or so of rifle powder. The hills for one second were lighted up, then as suddenly relapsed into gloom. The blaze at the ledge so close at hand was promptly doused, and the night rolled on, calm, placid, and unbroken.

When the first streak of dawn crept into the orient sky, Barclay's shadowy scouts were issuing from the San Saba on the farther side and halting for the coming of the main body. Neither those who led the advance nor those out on either flank, where flankers were at all possible, had seen a sign of outlaw, cowboy, even of human being, outside their own array. Not only had the Friday gang vanished from the neighborhood of the Pass, but, what was most mysterious, not a sign had appeared of paymaster or escort, who were due at Crockett's early this very morning. Brooks, picking out the lightest rider in his weary column, sent him on the liveliest horse to warn Pennywise and his escort, provided he could find him at the San Saba camp, of what had taken place, notify him that they would here await his coming, and meantime ordered dismount, unsaddle, and graze, and in two minutes every charger was divested of his load, and many of them were kicking and rolling on the turf.

Twenty-four hours had the command been in saddle, except for the required halts and a long two hours during the dead of night, when leading their wearied steeds or crouching beside them at rest, while Barclay and his scouts explored the overhanging heights and listened eagerly for sound of coming troopers from the eastward. But for the waning moon there would have been hours of total darkness. Ninety miles, all told, had they travelled, and now, wearied though they were, nine out of ten of the men were chafing with wrath that the wily gang had managed to escape them. Whither were they gone, and where on earth was the paymaster, were the questions. Certainly not through the Pass, for there were no fresh hoof-prints. Could it be that, balked in their plan to overwhelm the escort by this coming of at least an equal force, the gang had turned back angered and thrown themselves on Cramer's crippled party with the view of getting away with the horses, arms, and equipments? Certainly none of Cramer's people had made their way by the game trails over the range to join them, but there was reason for that: Lawrence had never succeeded in reaching Cramer.

Sad, wearied, and depressed, Major Brooks seated himself on a saddle-blanket to take counsel with his officers, now reduced to three,—Barclay, Winn, and the doctor. He missed Mullane, stanch old fighter that he was, for Mullane knew most of the country thoroughly, and had been posted for months at the Rio San Saba, now only some twenty miles to the east. He sorely missed Lawrence, for on him he had often leaned. He was beginning to take vast comfort in Barclay, to be sure, but now Barclay, Winn, the doctor, men and horses, the entire command, in fact, had come to a stand-still. There was no use in going farther east; there the country was comparatively open and rolling, and the gang would hardly dare attack forty troopers on the wide prairie. Besides, the nearest water in that direction was twenty miles away; the little rivulet rising in the heart of the hills was ten miles behind them, and already horses were thirsting and men emptying their canteens. Blankly the major stared up into Barclay's drawn and almost haggard face. "Can you think of anything we ought to do?" he asked, and, in asking, Brooks was a far better soldier than the man who, having exhausted his own resources, thought it infra dig. to invite suggestions from his juniors.

"Just one, sir. Sergeant McHugh tells me he once came out here hunting with Captain Mullane, and that they took a light spring wagon right over the range southeast of Crockett's, the way Cramer went. It is a much longer way round, but a more open way. The trail must lie some eight or ten miles off here to the south, or west of south. Could it be that the gang only started from the place of Cramer's ambuscade as though to go to the Pass and then veered around again and covered that trail, and for some reason have been expecting the paymaster that way after all?"

Worn and weary as he was, Brooks staggered to his feet at once, his face going paler still. "By heaven, Barclay, if that's possible, they've had uninterrupted hours in which to deal with Pennywise already! It is possible," he added, with misery in the emphasis of his tone. "I remember having heard of that trail, but never thought it practicable for an ambulance. Then there is work before us yet. Call Sergeant McHugh," he cried. The word was passed among the wearied groups, where, squatting or lying, the men had thrown themselves upon the ground, and presently, rubbing his red eyes, a stocky little Irish sergeant came trudging up to his commander and silently touched the visor of his worn old cap.

"Can you guide us by the shortest route from here to the trail you spoke of to Captain Barclay?" asked the major.

Mac turned and gazed away southwestward along the line of the San Saba hills.

"I don't think we could miss it, sir, if we followed the foot-hills."

"Then we must try it," said Brooks, decidedly, half turning to the silent officers as he spoke. "Let the horses graze ten minutes more and get all the dew and grass they can, then we'll push for it."

And so, just before five, hungry, weary, and weak,—some of the men at least,—the little squadron clambered into saddle and once more moved away. No need to leave any one to say which way they'd gone; the trail showed all that. Silently they headed for the broad valley of the Bravo, miles away to the invisible west. Once across a little rise in the falda, Brooks struck the slow trot he had learned long years before from the beloved major of his old regiment, and doggedly the column took it up and followed. Not a mile had they gone when the sun came peering up over the heights far in their wake; for a few minutes the dew flashed and sparkled on the turf before it died beneath that fiery breath, and still no man spoke. Sound sleep by night, a cold plunge at dawn, and the hot tin of soldier coffee send the morning tongues of a column en route "wagging like sheep's tails," say the troopers, but it takes a forced all-night march, following an all-day ride, followed by a morning start without either cold plunge or hot coffee, to stamp a column with the silence of a Quaker meeting. Let no man think, however, the fight is out of its heart, unless he is suffering for a scrimmage on any terms. Men wake up with a snap at sound of the first shot; dull eyes flash in answer to the bugle challenge, and worn and wearied troopers "take a brace" that means mischief to the foe at the first note that tells of trouble ahead. Just two miles out there came the test to Brooks's men, and there was none so poor as to be found wanting.

Two miles out, and the column woke up at the cry, "Yon comes a courier!" and coming he was, "hell to split," said Sergeant McHugh, from afar off over the rolling prairie to the southwest. Five minutes brought him within hail,—a corporal from the camp on the Rio San Saba, on foaming horse, who came tugging at both reins, sputtering and plunging, up to the head of column, and blurted out his news. "I thought you was the escort, sir,—the paymaster's escort. They left camp at nine last night, and at two this morning Corporal Murphy got back, shot, and said they were corralled in the hills on the old trail. The captain is coming along with twenty men, and sent me ahead. They must be ten miles from here yet, sir."

"The paymaster, or the captain?" asked Brooks, his heart beating hard, but his face imperturbable.

"Both, sir, I reckon; one one way and the other the other."

Then Brooks signalled over his shoulder. "We've got to gallop, Barclay. It's neck or nothing now." And some horses even then were drooping at the trot.

Six o'clock now. Six miles from the eastward mouth of the Pass, and spurs were plying here and there throughout the column, for many found their horses lagging sorely. Barclay on his splendid blooded bay was far out to the front, the corporal courier with him, for theirs were the only mounts that could stand another forcing of the pace. Rearward, three or four horses, exhausted, were being gathered up by a burly sergeant, and with their weary riders led slowly along the trail. Six-fifteen:—Barclay and his corporal were but dots along the falda now, and moving swiftly. Then at a higher point, in plain view, one dot began circling to the left at speed. Every man knew what that meant, and the signal was answered by another spurt. The sun was telling at last. The dew had dried, but along the turf there was but little dust to rise, and Brooks could keep most of his men together. Far off to the left, all eyes could see now the sign that told that rival rescuers were gaining. The little squad from the San Saba camp came spurring along the beaten trail, betrayed by the cloud of dust that rose above them. Young Connolly, the guidon-bearer of Barclay's troop, unfurled his color and set it flapping in the rising breeze in trooper challenge; and down the column set and haggard faces lighted up with the gleam of soldier joy. It was to be a race,—a race to the rescue. Six-thirty, and over a low ridge went Brooks and Winn, close followed by their orderlies; far away, midway up the opposite slope, stretched a slender, twisting, traversing seam,—the winding trail to Crockett's. The black dots in the lead were now three in number, darting towards two others, black dots, too, some four miles away and to the right front, right in among the hills. "Keep it up, lads! the quicker to water and rest!" are the major's words now, and spurs set home again, despite equine grunts in protest. Six-forty, and the dots in front are blacker and bigger and popping about, three of them, at least, in lively motion, checking suddenly, then darting to and fro, and the cry bursts from the leader's lips, "By God, they're at it! Now, lads, for all you're worth, come on!" Six-forty-five, and, rounding a projecting spur, a shoulder from the range, Brooks, Winn, and the doctor burst in view of a scene that banishes the last thought of weariness. Barely a mile or so away, a rocky ledge lies beyond and parallel with the trail. Its jagged crest is spitting smoke and fire. Its smoother slopes, towards the east, are dotted in places by the bodies of dead or dying horses, and in places, too, by other, smaller forms, apparently stiff and motionless. Off the trail, as though dragged there by affrighted and agonized animals, lies an overturned ambulance, its six draught-mules outstretched upon the turf about it; so, too, are other quadrupeds, troop-horses evidently. Well back of the ruined wagon, some trusty soul has rallied the remaining troop-horses, while most of their riders, sprawled upon the turf or behind improvised rifle-pits, stick manfully to their duty. "Friday's" ambuscade, in the still hours of the night, has cost the government heavily in horses, men, and mules, but old Pennywise's precious safe is guarded still, and every rush the outlaws make to get it is met by relentless fire. Six-fifty, and, leaving on the field six outlawed forms that will never fight again, the baffled relics of the Fridays are scurrying away into the fastnesses of the range before the labored rush and sputtering fire of Brooks's men, and Galahad, with his corporal comrade, far in the lead, gets the last compliments of the departing gang. Another gallant horse goes down, and Galahad's for the time goes free, his rider falling fainting from exhaustion and loss of blood.
