On October 23, 1864, a wagon train of refugees had come from Fort Smith, Arkansas, and was escorted by troops from the 6th Kansas Cavalry under the command of Col. William Campbell. These were local men from Cherokee, Crawford, and Bourbon counties. Their enlistment was over, and they were on their way to Fort Leavenworth to be dismissed from service. They ran into the 1st Indian Brigade led by Maj. Andrew Jackson Piercy near the current Pittsburg Waste Water Treatment Plant. They continued to the north when a small group of wagons broke away in an unsuccessful rush to safety. The Confederate troops caught up with them and burned the wagons. The death toll was three Union soldiers and 13 civilian men who had been with the wagon train. It was likely that one of the Confederates had also been killed. A granite marker memorial for the "Cow Creek Skirmish" was placed near the Crawford County Historical Museum on October 30, 2011.
