Their mode of besieging these places, though not at all conformable to the notions of a siege derived from the tactics of a civilized people, was dictated by the most profound practical observation, operating upon existing circumstances. Without cannon or scaling ladders, their hope of carrying a station, or fortified place, was founded upon starving the inmates, cutting off their supplies of water, killing them, as they exposed themselves, in detail, or getting possession of the station by some of the arts of dissimulation. Caution in their tactics is still more strongly inculcated than bravery. Their first object is to secure themselves; their next, to kill their enemy. This is the universal Indian maxim from Nova Zembla to Cape Horn. In besieging a place, they are seldom seen in force upon any particular quarter. Acting in small parties, they disperse themselves, and lie concealed among bushes or weeds, behind trees or stumps. They ambush the paths to the barn, spring, or field. They discharge their rifle or let fly their arrow, and glide away without being seen, content that their revenge should issue from an invisible source. They kill the cattle, watch the watering places, and cut off all supplies. During the night, they creep, with the inaudible and stealthy step dictated by the animal instinct, to a concealed position near one of the gates, and patiently pass many sleepless nights, so that they may finally cut off some ill-fated person, who incautiously comes forth in the morning. During the day, if there be near the station grass, weeds, bushes, or any distinct elevation of the soil, however small, they crawl, as prone as reptiles, to the place of concealment, and whoever exposes the smallest part of his body through any part or chasm, receives their shot, behind the smoke of which they instantly cower back to their retreat. When they find their foe abroad, they boldly rush upon him, and make him prisoner, or take his scalp. At times they approach the walls or palisades with the most audacious daring, and attempt to fire them, or beat down the gate. They practice, with the utmost adroitness, the stratagem of a false alarm on one side when the real assault is intended for the other. With untiring perseverance, when their stock of provisions is exhausted, they set forth to hunt, as on common occasions, resuming their station near the besieged place as soon as they are supplied.
