20 January 1865; Dodge City, Kansas: Sutler supply trains destined for Fort Lyon left Fort Larned on 17 January, escorted by 25 men of the 1st Veteran Colorado Cavalry and 6 men of the 2nd Colorado Cavalry. They proceeded unmolested for three days, until they reached Point of Rocks, or Nine Mile Ridge, 65 miles west of Fort Larned and about 2 miles west of present-day Dodge City, Kansas. There, about 45 Cheyennes and Arapahos attacked.
In the skirmish, three Indians were killed and three were wounded. One private was killed and two were wounded. The trains were so harassed that they returned to Fort Larned.
