The collapse of the Ghost Dance movement and the Massacre of Wounded Knee
in 1890 effectively ended armed hostilities between whites and Native
Americans.  Nevertheless, the U.S. Army remained an important factor in
America's westward expansion.  More forts were opened, regular patrols
established, and military authorities continued to intervene in
Indian-white affairs.  This photo shows the Second Cavalry at Zuni Pueblo
in New Mexico in 1897; it was sent there to arrest Indians who had broken
the law.  The military's presence near the reservations only further
isolated, alienated, and weakened the financial and moral strength of the
Indian tribes.
