The Plains Indians life had already taken a drastic change by the introduction of horses. When settlers were first migrating west, they had little trouble with the Indians, and even traded with them for supplies. However, when more people started to migrate, that is when the fight began. The army moved in and fought with the Indians. The Government put in a peace policy to no avail. Even after the peace policy was put into place, the army continued to obliterate the Indians way of life by destroying their homes, horses, and buffalo.
