The Siege of Charleston 1861-1865, by E. Milby Burton:
The first shell fell at 1:30 AM on August 29; it landed on Pinckney street and started a lively blaze. The first fire company to reach the scene was composed of free Negroes, who all through the war did valiant service in fighting fires started by shells.
