The Fetterman Fight alone accounted for 81 of the killed.

The livestock taken or destroyed during the campaign represented a significant logistical loss that the available records don’t fully capture.

Civilian casualties — emigrants who were attacked on the trail, workers who were killed in raids on settlements adjacent to the trail zone — added to the overall cost of the conflict, though precise numbers are harder to establish.

Against these costs, the economic benefit of the Bozeman Trail to American interests was essentially zero during the period of active resistance.

The trail had carried thousands of emigrants in 1864 and 1865, before the resistance became intense.
