The Friends of the Hunley will celebrate the sub's 150th anniversary by expanding tours, cutting ticket prices and hosting an anniversary reception next weekend.

Feb. 17 marks the 150th anniversary of the Confederate sub H.L. Hunley's attack on the USS Housatonic off Sullivan's Island, the first time a submarine sank an enemy ship in battle.

The Warren Lasch Conservation Center, home of the Hunley, will open from 10 a.m. to 5 p.m. Feb. 14. On that day active and retired military personnel will get half off the $12 admission.

On Feb. 17, the center will open from 10 a.m. to 5 p.m. and tours will be $1.50 in honor of the anniversary.

On Feb. 15, the Friends of the Hunley will host a reception and lecture from project genealogist Linda Abrams, who will discuss the men who sailed the Hunley on its final voyage. Tickets to the 6 p.m. event at the Lasch Center are $50.

At 7 p.m. on Feb. 17, the Confederate Heritage Trust will hold a living history demonstration and a ceremony at Breach Inlet on Sullivan's Island, where the Hunley sailed from on its final voyage.
