The scouts are appointed by the leader and changed daily; their duty being to separate and keep 5 or 6 miles ahead of the main body. These scouts or discoverers are footmen and use the same precautions as before stated. The main body moves slowly forward after reconnoitering has commenced, without any order, and only passing whatever ground has been rendered secure by the reconnoiterers. During the time before arriving in their enemies’ country, or at least before any signs of enemies have been perceived, they run buffalo with horses, kill enough meat for present use and dry and pound more to be used when hunting is not advisable. When signs of the camp are perceived, sentinels are posted every night, who lie down around the camp within 200 or 300 yards of the main body, and 50 or 60 steps from each other. All the horses belonging to the expedition are picketed within this circle and near the place where their several owners sleep. These sentinels are changed every night.

When by means of scouts and other observations they have discovered the camp it is approached in the night and the several advantageous positions which the ground affords around it are occupied by different detachments of the party, who are to attack from various quarters as nearly as possible at the same time. About daybreak a rush is made by the mounted men, shouting the war whoop and firing into the lodges as they pass through. The attention of the horsemen is directed toward driving off every horse found in camp. These, although picketed, take fright at the noise, snap their cords and are driven away. This rush only passes through the camp, and the enemy being raised and armed turn out and pursue and a battle now takes place near the camp. Indian fighting is individual fighting, each one for himself, without any military order, line, or file. Orders are given by any of the chiefs or soldiers in a loud voice when some advantage presents itself. Both parties endeavor to cover their bodies by any objects which are in the way. A thicket is much desired, small trees, stones, bunches of grass, or hollows made by the rain are all occupied, and those who cannot find any shelter jump from side to side, never standing still a moment to avoid any certain aim for their enemy’s fire.

The whole is accompanied with a terrible yelling on both sides. When one falls on either side the war whoop is sent forth by the party who killed and a simultaneous rush is made by the enemy to obtain the scalp and the friends of the fallen man to rescue the body. In these mêlées of small parties take place the terrible savage struggles for which they are remarkable. It is hand-to-hand fighting by a few on each side over the body of the fallen man.[26] Knives, lances, and war clubs are the arms then used and frequently several fall on each side before one party recoils. These scenes are going on over several parts of the field at the same time. The war whoop is sounded from either side whenever any success is visible, and when any disproportionate loss takes place the flight of that party is the consequence. This is the great aim of either party, as a massacre of the scattered fugitives then takes place. It should be remembered that when the contending parties are nearly equal very little damage is done.

The firing is at such a distance that only a random shot takes effect, and after abusing each other and firing hundreds of shots all day, perhaps only three or four are killed. There must be a great superiority of numbers and position on one side where there is any great destruction. The greatest loss of life happens when some 200 to 400 warriors surprise a camp of 20 or 30 lodges, or when the war party is too large to effect concealment for stealing horses, and too small for defense. In this case when pursued by the whole camp they are brought to a stand. If on the prairie they take up a position on the top of some hill covered with stones with which they make a barricade or seek a gully or cluster of bushes. Here they fight as long as one of them is living, but being surrounded by a superior force are all killed in the end. Three years since 52 Assiniboin who were discovered in an attempt to steal horses from the Blackfeet were pursued and brought to bay in a sink hole, or gully, where they were surrounded by about 800 men of the latter nation and fired upon until all were killed.

Their enemies, however, lost 34 men before they succeeded. A retreat is ordered in words to that effect and the movement being perceived is followed by all, which generally ends in downright flight. A very common exhibition of individual bravery is, when the parties are equally divided, and slow skirmishing going forward, each party having good positions, a single warrior rides forth near the place where the other party is stationed, and riding slowly within reach of their fire along their front, sings his war song and calls out his name, presenting a mark for the whole of his enemies to fire at. Either he or his horse is generally killed, or if he escapes he is considered a brave man ever afterwards. In either case he is followed by one of the opposite side in the same manner, and in this way often three or four are killed. They eat no root supposed to have the power of deadening pain or inspiring courage.

The divining men are consulted as to the nature of their dreams before they set out, and on the march, but not in regard to their operations in battle.

Battles are planned as soon as they can determine the position of the enemy, which plans are changed according to circumstances afterwards, but the fighting is done at random, each loading and firing when he chooses, and using any measures of concealment of his person.

No general orders are conveyed or aids employed, although whenever a cluster of men occupy a position some soldier or chief being there gives orders to the others, individually or collectively, as the danger is apparent. The chiefs and soldiers retreating would be a signal for all to run. The leader gives advice occasionally as to dislodging the enemy, etc., but all his orders partake of the nature of requests. They rally often during a retreat if the party be large, and keep up a running fight for 10 or 15 miles.

A favorite device to decoy enemies is to send but few to make an attack on their camp and drive off the horses. The camp, following, are led to where the main body lies in ambush.

The war whoop is the signal of advance and also of encouragement during the fight. It is also a cry of joy when any of the enemy fall, and at all times a defiance, but never used in retreat or under any humiliating circumstances. They speak to and abuse each other during the fight, adding their former deeds to exasperate the enemy and induce some one of them to step forth that he may be killed.
