Pittsburg is a city in Crawford County, Kansas, United States, located in Southeast Kansas near the Missouri state border. It is the most populous city in Crawford County and southeast Kansas. As of the 2010 census, the city population was 20,233.
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.
