Union Ironclads, (Passiac Class Monitors), bombing Fort Moultrie on Sullivans Island September 8, 1863. This view was photographed from one of the Confederate emplacements, the ships are identified as (from left to right): USS Weehawken, USS Montauk and USS Passaic. The monitor on the right appears to be firing its guns. The date is given as 8 September 1863, when other Monitors were providing cover for the Weehawken, which had gone aground on the previous day. She was refloated on the 8th after receiving heavy gunfire from the Confederate fortifications. The Weehawken was hit 24 times, but only one shot went into the unprotected hull below the armored belt. It was a 7” hole, probably a bolt from Battery Marion's treble-banded Brooke rifle which fired many rounds with maximum charges, at 20 pounds of powder behind 120 pound bolts.
