During the Civil War, many of Caseyville's residents were Confederate sympathizers, and Confederate troops used the community as a base during skirmishes in October 1862. After the Confederates seized a Union steamboat, Union troops at Battery Rock entered into a standoff with the troops at Caseyville. The Confederates eventually left the town, and the Union Army entered the city; after temporarily arresting every male resident of the town and charging a fee for damages to the steamer, the army mandated that the town bar Confederate troops from entering.
