In South Carolina, an underwater telegraph cable in Charleston Harbor links Forts Moultrie and Sumter
The firm of Seville, Denbigh, and Hobbs completed the laying of the underwater cable in Charleston Harbor linking Fort Moultrie with Fort Sumter. The event was commemorated with the firing of a combined salute from the forts, ordered over the new communication. (By John Osborne)
