History On February 25, 1779, Col. George Rogers Clark captured Fort Sackville at Vincennes from the British. About west at Pointe Coupee on the Wabash River on March 2, 1779, Capt. Leonard Helm commanding three boats and 50 volunteers from Vincennes captured a reinforcement fleet of seven boats carrying 40 soldiers and valuable supplies and Indian trade goods.

A Kentucky soldier killed a fellow Kentuckian, Clark, either accidentally or in a grudge fight. The deceased was buried at the top of a hill that became the Mann Turman Cemetery. General Harrison and his troops continued north on the Wea Indiana Trail to build Fort Harrison and then proceeded to the Battle of Tippecanoe.

Pioneer heroine of abdominal surgery Jane Todd is buried in Sullivan County. Born in Virginia in 1763, she and her husband, Thomas Crawford, moved to Green County, Kentucky, in 1805. Suffering from a huge abdominal tumor, she rode to Danville, Kentucky, to submit to a never-before-performed surgical procedure. On Christmas Day 1809, Dr. Ephraim McDowell performed the first ovariotomy, in his home. The ordeal lasted 25 minutes. There was no anesthesia. Mrs. Crawford recovered completely and years later came to Graysville to live with her son, Thomas, a Presbyterian minister. She died in 1842 at age 78. The restored McDowell home in Danville, Kentucky, is a surgical shrine.

However, Sheriff Dudley ultimately remained in office after he and other officials entered into a legal battle about the decision.
