​Edward Wanshear ​​Wynkoop was a founder of the city of Denver, Colorado. He served as an officer in the First Colorado Volunteer Cavalry during the Civil War, attaining the rank of major of volunteers. While post commander at Fort Lyon, Colorado in 1864 he encouraged peace negotiations with the Cheyennes, but was transferred in November to Fort Riley, Kansas. He was posted there at the time of the Sand Creek Massacre, and on behalf of the US Army investigated Colonel John M. Chivington's conduct in the event. Wynkoop's report led to Chivington's condemnation. ​​In 1866, Wynkoop became an Indian agent for the Southern Cheyennes and Arapahos, resigning in December of 1868 in protest of the destruct​​ion of Black Kettle's village in the Battle of Washita River. He later became warden of the New Mexico penitentiary.
