@Animasta: No.... The Sullivan Expedition was directed against the natives who sided with the British though there may have been collateral damage.
Most natives did side with the British, because they were hoping to stop the colonists from expanding farther west. Who knows what would have happened if the British won though, it may have been better for them, or not.
I mean if you consider the native populations of the USA and the native populations of Canada today you would find that it would indeed have been better for them.
but I distinctly remember reading that washington directly fucked up native americans who sided with the british and some that did not, so...
Even if that is the case (Which does seem likely.) it's important to remember that this was a war, and the Natives (Directed by the British) were raiding the Colonists as well. In fact one of the worst actions of the war was the Cherry Valley massacre, which was exactly that.
It's likely that some villages that supported the Americans were destroyed, but Washington's orders were specifically to target the villages that were hostile to the American cause.
I don't want to defend his actions too much. I don't think you can read history books and think that the native Americans were treated fairly by the Colonists by any stretch of the imagination, but laying that blame on Washington seems misplaced.
