10-Inch Mortar, Model 1819
This 10-inch mortar, unearthed during the excavations in 1959, is similar to the one which fired the signal shot from Fort Johnson on April 12, 1861. Later in the war, the Confederate defenders of Fort Sumter mounted several of these weapons near this spot as added defense against the anticipated assaults of the Union Army and Navy.
