Leading up to the Civil War, there were a few skirmishes between Union forces and Confederate forces. Most of these were near forts in Confederate territory that were occupied by Union forces. One of those skirmishes happened to be in Charleston Harbor on April 11, 1865 where USRC Harriet Lane fired upon the steamship Nashville. Because of this “skirmish” was a Union Navy ship firing upon a civilian ship in a southern controlled harbor, the Confederacy claimed that the Union fired the first shots of the war between the two and General Beauregard to attack Fort Sumter on April 12, 1865.
Because “winners of war write history,” we now have issues of the actual records of the event. Some records indicate that this event took place on April 11, 1865 and other records has this event taking place on April 13, 1865.
