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. The steamboat was destroyed, the cargo was lost, and the tiny Union escort was run off. The loss did not affect the Union war effort, however.
There were a variety of specialized flatboats to ship cargo to the world markets. Some flatboats were built with raked bows to be used on return trips alongside steamboats, serving as fuel flats, first hauling wood, than coal. These flatboats with raked bows evolved into coal boats. Coal boats were tied together in fleets to be pushed by steamboats.
