Bass Reeves organized these expeditions methodically. He traveled with a wagon, a cook, and sometimes a Native American posseman — someone who knew specific areas of the territory, could communicate across the tribal boundaries that divided the landscape, and could provide help that a single deputy could not provide alone. The wagon carried supplies, cooking equipment, and eventually the accumulated prisoners. The cook was responsible for feeding the party; the posseman was responsible for navigation and local knowledge.
The Indian Territory of this period was divided not just by law but by landscape and community. The Cherokee Nation occupied the northeastern corner, between the Arkansas border and the Kansas border, with its capital at Tahlequah. The Creek Nation occupied the center. The Choctaw and Chickasaw nations held the south and southeast, bordered by the Red River on the Texas side. The Seminole occupied a smaller area in the center-west. Each had its own government, its own laws, its own language, its own understanding of how the land should be used and by whom. A deputy moving through this landscape was moving through multiple overlapping sovereign entities, each of which had its own relationship to federal authority.
The practical effect on Bass Reeves’s work was significant. He needed to be able to communicate across these boundaries — which is where the years he had spent in Indian Territory before his appointment became professionally important. He could speak some Seminole and some Creek. He knew how to read the land through long experience with it. He knew which routes connected which communities, which crossings were reliable and which were dangerous in high water, which areas required particular caution because of the density of people who had come to Indian Territory specifically to avoid arrest.
