Cause

Following the outbreak of the Civil War, the Creek Nation became divided between Union and Confederate sympathizers. Union-loyal Creeks under Chief Opothleyahola refused to honor Confederate treaties and sought to relocate to Kansas, where Union forces could offer them protection, prompting Confederate authorities to move against them.

Event

On November 19, 1861, Confederate forces intercepted and attacked the column of Union-loyal Creek refugees led by Opothleyahola at Round Mountain, the first battle of the Trail of Blood on Ice campaign. The exact site remains disputed, with historians placing it near either Keystone or Yale, Oklahoma.

Consequence

The battle launched a series of engagements collectively known as the Trail of Blood on Ice, as Opothleyahola's followers continued their difficult winter flight toward Kansas. The conflict demonstrated that the Indian Territory would be a significant arena of Civil War operations, with Native nations drawn directly into the struggle.
