This article talks about the long process Major Ridge and John Ross fought to save the Cherokees, but lost to Andrew Jackson. They tried every strategy and knew how to use the system, but could not get around the very stubborn Jackson:
By 1813, Ridge had seen enough of politics to understand the diplomatic advantage to be gained from joining the Tennesseans against the Red Sticks. The Cherokees might even have realized that advantage had it not been for the militia leader they fought under: Andrew Jackson.
As a boy in the 1770s, Jackson had listened to stories of Indian violence toward settlers, and with no apparent understanding of their motives, he developed prejudices that he—like many Americans of his day—held throughout his life. He routinely called Indians “savages” and people of mixed heritage “half-breeds,” and he was unshakable in his conviction that Indians should be removed from the South. When news that the Red Sticks were attacking settlers reached him in Nashville, he asked: “Is a citizen of the United States, to remain under the barbarous lash of cruel and unrelenting savages?”
In March 1814, Jackson tracked the Red Sticks to Horseshoe Bend, a peninsula formed by the Tallapoosa River in what is now Alabama, and launched a frontal assault on their breastworks. His troops might have been repulsed had the Cherokees not crossed the river and attacked from the rear. Caught between two attacking forces, the Red Sticks lost nearly 900 warriors in what proved to be the decisive battle of the war.
That day, a Cherokee named Junaluska saved Jackson from an attacker, prompting the Tennessean to declare, “As long as the sun shines and the grass grows, there shall be friendship between us.” But in the peace treaty he negotiated with the Creeks, Jackson confiscated 23 million acres of land in Alabama and Georgia—some of which belonged to the Cherokees.
The list of the methods Ross and Ridge tried are impressive and should have worked - the courts even agreed with them. Jackson did not, though, and Jackson won, albeit unfairly (yes, yes, I'm siding with them, not Jackson...I usually don't takes sides, but I'm sorry....Jackson was clearly in the wrong and this is not a stellar moment for him or the US).
