Who forced the Navajo to leave their land?

Kit Carson and the USArmy defeated most of the Navajo people in 1864 and forced them to march about 450 miles in the Long Walk to Fort Sumner in NM territory ( also known as Bosque Redondo) in 1864. Brigadier General James H. Carleton ordered Carson to kill all the men of the tribe. He refused and tried to resign in February 3, 1863. His resignation was rejected. Under Carleton's direction, Carson instituted a scorched earth policy from Sept 1863 to Jan 1864. Carson got the Ute tribe, longstanding Navajo enemies to assist in burning crops, fruit trees, and homes and killing all livestock. About 10% died on the forced march to Ft Sumner and the bad conditions in the internments camps in the next four years.

Some, were never defeated and hid out especially on the northern flanks of Navajo Mountain with Hoskinini. Other's surrendered to protect their people. For example Ganado Mucho, in Navajo known as Totsohnii Hastiin ( man of big water clan), turned himself and his people in when he heard people were starving. He brought his huge herds to Ft Sumner with him.

In 1868 they were allowed to return to their ancestral homeland.
