Batteries Hentig and Dodd
The 1890s modernization continued
By the turn of the century, Fort Delaware had become part of a coastal defense system, linking Fort Mott in New Jersey and Fort Dupont in Delaware. Batteries* Hentig and Dodd, which each housed two rapid-fire guns, were intended to furnish close-range support for the submerged electric cables and torpedo net. Both batteries were named in honor of army officers who had died in action.
