Lyndon Monroe (1865-) was a US Army captain who, in 1899, was sent to head a military delegation from Washington DC to Fort Wallace, South Dakota to calm the rising tensions between the Fort Wallace garrison and the Wapiti Native Americans on the Wapiti Indian Reservation. Monroe's Indian sympathies led to Colonel Henry Favours attempting to have Monroe tried and hanged for treason, but Monroe was rescued by the outlaw Arthur Morgan and put on a train back to the East, where he was safe.
Biography[]
Lyndon Monroe was born in New York City, New York in 1865, and he graduated from West Point before being commissioned as a US Army lieutenant. In 1899, he was sent from Washington DC to South Dakota to head a military delegation to Fort Wallace to try to reduce the rising tensions between the Wapiti Native Americans and Colonel Henry Favours' garrison. Monroe sympathized with the Natives and actively fought for their land rights, lobbying on their behalf to the Bureau of Indian Affairs and the Mayor of New Orleans in an attempt to stop Leviticus Cornwall from obtaining an oil drilling contract on the Wapiti Indian Reservation. When this failed, Monroe persuaded the Wapiti chief Rains Fall's white associate, the outlaw Arthur Morgan, to help him obtain vaccines for the tribe by hijacking an Army wagon carrying vaccines withheld from the reservation; while Monroe insisted that Morgan should do so cleanly, Morgan was ultimately forced to gun down both of the wagon drivers. During their conversations, Monroe also warned Morgan that Colonel Favours was actively seeking to instigate Native retaliation against his actions in order to justify a war, and warned that a dangerous culture was developing within the regiment itself, one which preached hate and violence against the Wapiti natives.

Monroe at the train station
After a series of escalations of violence, a conference was held at Fort Wallace in which Favours, Rains Fall, Monroe, and Morgan were in attendance, and Favours argued with Monroe because of his friendship with the Indians and announced that Monroe would be arrested and tried for treason for sabotaging the Army's efforts. Morgan stepped in, taking a hostage and forcing Favours to release Monroe. He and his fellow outlaw Charles Smith proceeded to engage in a shootout with the soldiers as they helped Monroe escape, and Morgan proceeded to take Monroe to Emerald Station in Oklahoma, where he purchased him a train ticket to Washington, as he faced a possible death sentence in South Dakota for treason and insubordination. There, Monroe thanked Morgan for his help and for saving his life, and Morgan gave Monroe some money and bade him farewell as his train left.
