This is a pair of black and white lithographs. They are matted and ready to frame. The top lithograph measures 6 3/4″ x 4.” It shows the Confederate States of America (CSA) Ironclad C. S. S. Virginia shelling Union frigates on 8 March 1861 at Hampton Roads, VA. On that date the Virginia sank two Union frigates. On the morning of 9 March 1862, the Virginia, more commonly known as the Merrimack (her Union name before she was scuttled and raised by the CSA to be rebuilt as an ironclad) met the U. S. S. Monitor in the first battle of iron ships. This revolutionized the world’s navies. The two vessels fought to a draw. Nevertheless, sailing vessels were soon replaced by iron vessels. The lower lithograph, which measures 11 1/4″ x 6 1/4,” shows Fort Sumter in the harbor of Charleston, SC in 1863. Fort Sumter was shelled in April 1861 by CSA forces and the Union garrison surrendered. This lithograph shows the Fort occupied by CSA troops and being shelled by a Union Naval Fleet.
