In Charleston Harbor, Confederate Fort Moultrie suffers a massive magazine explosion under U.S. Navy gunfire

Fort Moultrie, defending Charleston Harbor from its position on Sullivan's Island, had been under serious bombardment for months.  A 15 inch shell from the U.S.S. Weehalken struck home in one of the fort's magazines and caused a massive explosion. The damage was severe but the fortress still held and was not abandoned until February 1865, by that time almost only rubble.  (By John Osborne)
