I don't dispute that the other NW tribes might well have risen.

They would have lost, though.

By 1877 there were just too many Euro- and African-Americans (gotta be politically-correct these days before the PC police pull me in) in the USAicon for the Native Americans to win. After the War Between the States the US would not have allowed any section of what became the Lower 48 to be detached from the political control of Washington.

Between the surviving veterans of the War Between the States and the numbers of young men who grew up with stories of heroism, manhood and endurance (this was allowed in that dim benighted age) there would have been plenty of manpower AND experience needed to turn that manpower into good troops. The railroad already crossed the plains and could have brought as many troops and supplies as needed.

Basically, the last chance the Native Americans had to remain independent died with Tecumseh. And it was a slim chance then. There's only so far guts and skill will get you against a determined enemy with vastly superior numbers.
