Available as a Juniper Gallery Fine-Art Print, "Fate of the Rebel Flag" is the second of a pair of patriotic lithographs with a militantly Unionist theme based on paintings by William Bauly and issued by New York art publisher William Schaus in September 1861 at the start of the Civil War. In a spectacular nocturnal scene, a large warship sinks and burns, the flames taking on the configuration of the first flag of the Confederacy, the blue field with seven stars being formed by the night sky. Lightning strikes the flag from the upper left. View full size.
