In mid-November 1863 the relentless Union assault against Confederate held, Charlestown Harbor continued. From November 7 through the 10th 1753 rounds pounded Fort Sumter’s brick and earthen walls, with few Confederates wounded.
From November 12 through the 15th a total of 2328 additional rounds were fired, with two Sumter defenders killed and five wounded. On November 16, 1863 while engaging Confederate batteries on Sullivan’s Island in Charlestown Harbor the U.S.S. Lehigh, a monitor built on John Ericsson’s design, ran aground and was badly damaged before her crew could re-float her.
Five Union sailors later were awarded the Congressional Medal of Honor for helping to free the vessel during this incident. Clearly, the battle for Charlestown Harbor and Fort Sumter was costly to both the Union and the Confederacy.
