Today in history: Hunley mishap

On Oct. 15, 1863, the Confederate submarine sank for the second time off Charleston, S.C., while performing a routine diving exercise. All eight men on board, including H.L. Hunley himself, succumbed. The sub was retrieved and put to use again, eventually sinking a Union warship before it, too, went under.

Students build Hunley lantern replica

A group of Hamburg Area High School students are working to solve a mystery that's nearly 150 years old. Two witnesses reported seeing a blue light in the waters off Charleston, S.C., when the submarine H.L. Hunley attacked Union ships. It is speculated the Hunley's lantern cast that light, so the researchers have asked the Pennsylvania students to re-create and test a working lantern replica. • Article
