General Wm. H. Harrison's army made its last camp in Sullivan County at Big Springs on Sept. 29, 1811, using Benjamin Turman's fort as headquarters. With spring water available, it was an ideal location for 1000 men, including 160 dragoons and 60 mounted riflemen. While there, a Kentucky soldier killed a fellow Kentuckian, Clark, either accidentally or in a grudge fight, and Clark was buried at the top of a hill that became the Mann-Turman Cemetery. Harrison and his troops then continued north on the Wea Indian Trail to build Fort Harrison and then on to the Battle of Tippecanoe.
