How did dunbar end at fort sedgewick?

Dunbar ended up at Fort Sedgewick primarily as part of the military's efforts during the Indian Wars, particularly in the context of the conflicts surrounding the Great Plains and the protection of settlers. After the defeat of General Custer at the Battle of Little Bighorn in 1876, Dunbar and his troops were sent to reinforce the area and maintain order. Fort Sedgewick served as a strategic outpost for the U.S. Army, where troops could regroup and plan further operations against Native American tribes in the region.
