In July, under orders from Gen. Carleton, Col. Kit Carson began a simultaneous campaign against the Mescelaro Apache and Navajo. In a series of raids and skirmishes Carson's troops began rounding up Navajo and Apache and sending them to Bosque Redondo. Between September 1863 and January 1864, Carson and his men chased the Navajo, killing and capturing a few. Crops were burned, stock was confiscated, hogans were burned.
