The correct answer is "they received solemn promises from the government that they would be left alone and provided with supplies on the remaining land."
In post-Civil War America, Indians surrendered their lands only when they received solemn promises from the government that they would be left alone and provided with supplies on the remaining land.
And as we know, the situation became complicated and although they were sent to the Indian territory, modern-day Oklahoma- Native American Indian tribes felt betrayed because they always claimed that those original lands were theirs and belonged to their ancestors. And they were right. Native Indians were already in North America many years before the arrival of the white English colonists that founded the colonies in 1607.
