The Ambush of the steamboat J. R. Williams, which was carrying supplies from Fort Smith to Fort Gibson along the Arkansas River on July 16, 1863 demonstrated this.

Robert Fulton made the first steam-powered engine to power a steamboat, and in 1807 he demonstrated its use by going from New York City to Albany via the Hudson River. His steamboat was able to carry raw materials across the Atlantic Ocean by the mid 1800's. The roads also improved immensely during this time period. Previously, people traveled using animals or by foot, but there were many problems with the conditions of the roads.
