The Robert E. Lee Steamboat was nicknamed the "Monarch of the Mississippi" and built in New Albany, Indiana in 1866 for a price of $200,000. The grand steamboat was 297 feet by 49 feet. While the name was being painted on the ship it was moved over to the Kentucky shore as some Hoosiers resented the name of the rebel leader being used.

On June 30, 1870 the steamboat left New Orleans in a race against the Natchez to St. Louis.  At the time the Natchez was the then-current speed record holder.  The Henry Tate, MayFlower, Mary Alice and Tahlequah preceded the two steamboats up the river for a way with excursionists in order to be able to view the race. The Robert E. Lee won with the time of 3 days, 18 hours, 14 minutes.

She was eventually dismantled in Jeffersonville, Indiana, in the spring of 1876, to build the Robert E. Lee (2nd).
