Harrison sold the town site to Harvey Heth in 1808, a government surveyor and large landowner. Heth donated the town square for public use, and sold individual lots to settlers and the government. In 1809, Corydon was joined by road to Doup's Ferry, 15 miles (24 km) to the south in Mauck's Port. This gave access to the Ohio River for trade. Corydon sent a mounted militia company company nicknamed the Yellow Jackets to support the US army in the War of 1812. They fought in the Battle of Tippecanoe.
