Is that ... cannon fire, you say? Downtown? Yep.

BOOM! What’s that sound?

Oh, nothing. Just Gen. William T. Sherman and his troops firing on Columbia. (Argh, not again!)

You might hear a little noise near downtown Saturday, as Civil War reenactors commemorate 152 years since Columbia’s “Longest Day” with cannons and gunfire.

Four Union cannons will fire blanks from the west side of the Gervais Street bridge, while Confederate sharpshooters defend the city from the east side.

West Columbia police will close Alexander Road in front of the Riverwalk Amphitheater from 11 a.m. to 1:30 p.m.

The cannon fire will start around noon and last for about 15 minutes, according to the police department.

The “battle,” sponsored by the Lt. Gen. Wade Hampton Camp Sons of Confederate Veterans, will be from noon a.m. to 1 p.m. Saturday.
