It was commissioned in May 1847, cast in 1852, and dedicated on January 8, 1853, by Stephen A. Douglas.It was the first equestrian statue made in America. Jackson's horse at the Battle of New Orleans was named Duke; but Mills modeled the horse from his own horse named Olympus. Mills trained his horse to pose on its haunches. He completed a plaster model, and started a foundry to produce the casting. He produced six castings until the final one was completed, with ten pieces.
