There can be no plan of operations laid down, as they are as yet unaware of the position of the camp, how their horses are kept, what surrounding objects afford concealment, etc. In the night they approach the camp in a body under cover of the hills and bushes, and when near enough to see the horses, and judge of the opportunities of getting to them unobserved they again separate, and each pursues his own way of proceeding from different points, as the nature of the ground affords. The best horses of the Crows and Blackfeet are usually picketed near the lodge of their several owners and the rest grazing near. Sometimes pens are made around the lodges, the horses driven in at dark, and cottonwood bark thrown in for them to eat. The risk of extracting horses from the interior of a camp is very great, as young men are moving about from lodge to lodge all night in their various prosecutions of schemes on women; but the horses must be had, and the venture must be made. Near daylight, when all the people of the camp are supposed to be asleep, but when yet dark (and the darkest kind of nights are chosen) each warrior creeps slowly and silently toward that portion of horses apparently the best situated to be taken off unperceived. Should he in this way be so fortunate as to reach them without discovery he cuts the cords with which they are tied and works them gradually into the shade or darkness, then mounting one, drives the whole to the appointed place of rendezvous. But owing to the many obstacles in the way of each, the probability of some one being observed is great, and in that case the whole camp is alarmed on the instant, each rushing toward his horses. Shots are fired and the warriors seek safety in flight, with or without horses as it happens. If there be snow to show their tracks the enemy pursues them the next day, but if no trail can be found to follow they abandon it. In either case the warriors shape their course individually toward the appointed place of meeting, and if all are not assembled, leave some token for those not arrived to know they have passed, and continue their flight.
