That’s quite a web-site, thanks for sharing. I saved it to refer to later. Indeed the US Army was undefeatable..and everywhere. Custer only needed a couple of days and the Army could have had the entire 6 battalions did I read? right there to help. Bear in mind the idea was to capture and place Indian forces back on the reservation...which was encroached by gold miners..”chiefed by the double tongues” as Ten Bears said.
Time was against the Indians, as it usually is with aboriginal civilizations. Whether it be the military, civilization's advancement, the railroads, the slaughter of the buffalo, the Indian lifestyle was DOA. They just didn't know it, nor could they.
Unfortunately, while many in the military dealt with the Indians in a relatively humanitarian way (for the period, and after subjugation), the government in all its wisdom saw differently. Money was to be had and the Dept. of the Interior did everything possible to see that the proper parties were compensated while the Indians were left to shift. A sad tale.
