Answer:
The plan of the US administration toward the Indians in the time quickly preceding to the Civil War continued to stimulate the Indian community on to reservations.
Step-by-step explanation:
Native American communities on the fields in the west resumed armed disputes with the United States during the 19th century, into what was called commonly "Indian Wars." The Battle of Little Bighorn (1876) held one of the fastest Native American triumphs. Failures involved the Sioux Uprising of 1862, the Sand Creek Massacre (1864) and Wounded Knee in 1890. Indian Wars lasted into the early 20th century.
