An 1863 depiction of Black Terror

Black Terror was a fake warship used in the American Civil War to bluff Confederate forces into destroying the partially-salvaged remains of the ironclad USS Indianola. Union forces were advancing to control the Mississippi River and had made two attempts to capture Vicksburg, Mississippi, in 1862. Early the next year, the ram USS Queen of the West moved downriver to interfere with Confederate shipping on the Red River; Indianola was sent down a few days later. However, Queen of the West was disabled and captured after an encounter with Confederate field fortifications, and Indianola was severely damaged on February 24 after an attack by the repaired Queen of the West and CSS William H. Webb.

Not wanting Indianola to be repaired and enter Confederate service like Queen of the West, Union Navy officer David Dixon Porter had a fake ironclad constructed to bluff Confederate salvage workers into destroying the wreck of Indianola. A flatboat or barge was expanded with logs, and outfitted with fake cannons, lifeboats, and smokestacks. The fake vessel cost less than $9 (equivalent to $189 in 2020) and was named Black Terror. At 23:00 on February 25, the fake ship was released downstream, and successfully convinced the Confederates that it represented a real threat. Believing they faced an actual warship, the Confederate salvage crew of Indianola blew up the ship's remains, although some cannons were later recovered. The naval historian Myron J. Smith has since suggested that Black Terror was actually a later fake designed to reveal the location of Confederate artillery batteries, and that the story has been conflated with a possible earlier ruse aimed at forcing the destruction of Indianola.
