After his success with his steamboats in the Hudson, Robert Fulton decided to expand inland. In 1811 he had a 116 ft steamboat built in Pittsburgh for service on the Mississippi river. The first steamboat to be seen in that part of the world, she sailed down the Ohio and Mississippi rivers and made it to New Orleans without trouble. For the next three years she carried passengers and freight in the lower Mississippi between Natchez and New Orleans till she sank after striking a tree stump.
