After Indians have succeeded in stampeding a herd of horses or mules, and desire to drive them away, they are in the habit of pushing them forward as rapidly as possible for the first few days, in order to place a wide interval between themselves and any party that may be in pursuit.

In running off stolen animals, the Indians are generally divided into two parties, one for driving and the other to act as a rear guard. Before they reach a place where they propose making a halt, they leave a vidette upon some prominent point to watch for pursuers and give the main party timely warning, enabling them to rally their animals and push forward again.

TRACKING INDIANS.

When an Indian sentinel intends to watch for an enemy approaching from the rear, he selects the highest position available, and places himself near the summit in such an attitude that his entire body shall be concealed from the observation of any one in the rear, his head only being exposed above the top of the eminence. Here he awaits with great patience so long as he thinks there is any possibility of danger, and it will be difficult for an enemy to surprise him or to elude his keen and scrutinizing vigilance. Meanwhile his horse is secured under the screen of the hill, all ready when required. Hence it will be evident that, in following Indian depredators, the utmost vigilance and caution must be exercised to conceal from them the movements of their pursuers. They are the best scouts in the world, proficient in all the artifices and stratagems available in border warfare, and when hotly pursued by a superior force, after exhausting all other means of evasion, they scatter in different directions; and if, in a broken or mountainous country, they can do no better, abandon their horses and baggage, and take refuge in the rocks, gorges, or other hiding-places. This plan has several times been resorted to by Indians in Texas when surprised, and, notwithstanding their pursuers were directly upon them, the majority made their escape, leaving behind all their animals and other property.

For overtaking a marauding party of Indians who have advanced eight or ten hours before the pursuing party are in readiness to take the trail, it is not best to push forward rapidly at first, as this will weary and break down horses. The Indians must be supposed to have at least fifty or sixty miles the start; it will, therefore, be useless to think of overtaking them without providing for a long chase. Scouts should continually be kept out in front upon the trail to reconnoitre and give preconcerted signals to the main party when the Indians are espied.

In approaching all eminences or undulations in the prairies, the commander should be careful not to allow any considerable number of his men to pass upon the summits until the country around has been carefully reconnoitred by the scouts, who will cautiously raise their eyes above the crests of the most elevated points, making a scrutinizing examination in all directions; and, while doing this, should an Indian be encountered who has been left behind as a sentinel, he must, if possible, be secured or shot, to prevent his giving the alarm to his comrades. These precautions can not be too rigidly enforced when the trail becomes "warm;" and if there be a moon, it will be better to lie by in the daytime and follow the trail at night, as the great object is to come upon the Indians when they are not anticipating an attack. Such surprises, if discreetly conducted; generally prove successful.

As soon as the Indians are discovered in their bivouac, the pursuing party should dismount, leave their horses under charge of a guard in some sequestered place, and, before advancing to the attack, the men should be instructed in signals for their different movements, such as all will easily comprehend and remember. As, for example, a pull upon the right arm may signify to face to the right, and a pull upon the left arm to face to the left; a pull upon the skirt of the coat, to halt; a gentle push on the back, to advance in ordinary time; a slap on the back, to advance in double quick time, etc., etc.

These signals, having been previously well understood and practiced, may be given by the commander to the man next to him, and from him communicated in rapid succession throughout the command.

I will suppose the party formed in one rank, with the commander on the right. He gives the signal, and the men move off cautiously in the direction indicated. The importance of not losing sight of his comrades on his right and left, and of not allowing them to get out of his reach, so as to break the chain of communication, will be apparent to all, and great care should be taken that the men do not mistake their brothers in arms for the enemy. This may be prevented by having two pass-words, and when there be any doubt as to the identity of two men who meet during the night operations, one of these words may be repeated by each. Above all, the men must be fully impressed with the importance of not firing a shot until the order is given by the commanding officer, and also that a rigorous personal accountability will be enforced in all cases of a violation of this rule.

If the commander gives the signal for commencing the attack by firing a pistol or gun, there will probably be no mistake, unless it happens through carelessness by the accidental discharge of firearms.
