On September 28th, 1864, the Camp Weld Council was held . At this meeting, territorial governor John Evans met with Cheyenne & Arapaho Chiefs, including Black Kettle & White Antelope. The Arapaho and Cheyenne left the council believing that if they returned to Fort Lyon (in what is now Southeastern Colorado) they would be able to live in peace with the white settlers. Two months later, on November 29th, their camp at Sand Creek was attacked and many were massacred by Colorado Volunteers under the command of Colonel John Chivington. The Camp Weld Council was held at the current day 8th & Vallejo in the industrial section of Denver.
