From The Earth Is Weeping: The Epic Story of the Indian Wars for the American West, by Peter Cozzens (Knopf, 2016), Kindle Loc. 2321-2341:
The election of Ulysses S. Grant as president in November 1868 seemingly boded well for the army. After all, as commanding general he had defended Sherman and Sheridan’s hardfisted approach to the Indian problem and decried civilian meddling. But President-elect Grant was not General Grant, and to the surprise of the generals he welcomed ideas from the reformers, particularly the Quakers. Embracing their suggestion that religious men replace spoilsmen as agents, Grant gave the Quakers control over the two most critical—and difficult—Indian Bureau field operations: the Northern Indian Superintendency, comprising six agencies in Nebraska, and the Central Superintendency, which embraced Kansas and the “uncivilized” portion of Indian Territory (that is to say, the Southern Cheyenne and Southern Arapaho, and the Kiowa and Comanche agencies). The apportionment of these superintendencies to the Society of Friends became known as Grant’s Quaker Policy. To run the remaining superintendencies and agencies in the West, Grant selected honest and reliable army officers.
Grant also wanted to establish independent oversight of the Indian Bureau. To achieve it, he persuaded Congress to create the Board of Indian Commissioners. Composed of wealthy philanthropists, the board was given wide authority to scrutinize the operations of the Indian Bureau in Washington and in the field. And then Grant did something even more remarkable: he appointed an Indian to be commissioner of Indian affairs.
The new commissioner was Ely S. Parker, a full-blooded Seneca Iroquois sachem from upstate New York and a civil engineer who had risen to the rank of brevet brigadier general on Grant’s staff during the Civil War. Parker was a man of proven integrity. Although he subscribed to the prevailing view that the Indians’ future lay in acculturation, he nonetheless could be counted on to make it as painless as possible. In June 1869, Parker instructed his staff on their duties under the Grant administration: Indian agents and their superintendents were to assemble Indians in their jurisdictions on permanent reservations, get them started on the road to civilization, and above all treat them with kindness and patience. Indians who refused to settle on reservations would be turned over to military control, however, and treated as “friendly or hostile as circumstances might justify.”
Grant saw no humane alternative to his administration’s carrot-and-stick body of principles that the press labeled the “Peace Policy” and its concomitant policies of concentrating the Indians on reservations far from whites and of consolidating small reservations into larger ones populated by two or more tribes, which meant that tribes promised exclusive homes stood to lose them regardless of treaty guarantees.
