Wynkoop was placed in command of
Fort Lyon where tensions were high between the threat of
Confederate attack and inflamed tensions with the
Cheyenne brought about by attacks on the Cheyenne by US soldiers. As the threat of Confederate troops lessened and tensions with the Cheyenne increased,
Chivington, who was Wynkoop's superior, gradually shifted his concern towards the perceived threat from Cheyenne war parties. Cheyenne war parties joined forces with
Arapaho and
Sioux bands and launched attacks on settlers. In response to a letter by
George Bent asking for peace delegations and a hostage exchange. Wynkoop, with an escort of 127 men, two cannons, and the accompaniment of
Ochinee arrived at a tense peace negotiation. Despite initial signs of hostility, Wynkoop managed to secure four settlers who had been taken hostage and a pledge of the present chiefs, notably among them
Black-Kettle, to a future meeting with
Governor John Evans. Unfortunately, unbeknownst to Wynkoop, Evens and army command had soured at the idea of a peace treaty. While Governor Evans initially opposed meeting with the tribal chiefs, Wynkoop publicly delivered the chiefs to Evans, forcing Evans to meet with them at the risk of scandal. However despite what Wynkoop and the tribal chiefs present at the meeting believed, neither Evans or
Major General Curtis had any desire for peace. After Wynkoop's return to Fort Lyon, he was stripped of his command in favor of Major Anthony and soon after transferred to division headquarters in
Fort Riley,
Kansas to answer for an accusation of abandoning his post for his initial meeting with the Cheyenne. == After Fort Lyon ==
