Get some history? Ok, per wiki:
On December 11, 1861, an enormous fire burned over 500 acres (200 ha) of the city.
Union control of the sea permitted the repeated bombardment of the city, causing vast damage.
[78] Although Admiral Du Pont's naval assault on the town's forts in April 1863 failed,
[28] the Union navy's blockade shut down most commercial traffic. Over the course of the war, some
blockade runners got through but not a single one made it into or out of the Charleston Harbor between August 1863 and March 1864.
[78] The early submarine
H.L. Hunley made a night attack on the
USS Housatonic on February 17, 1864.
[79]
General Gillmore's land assault in July 1864 was unsuccessful
[28] but the fall of
Columbia and advance of
General William T. Sherman's army through the state prompted the Confederates to evacuate the town on February 17, 1865, burning the public buildings, cotton warehouses, and other sources of supply before their departure.
So. Two fires during the Civil War. First one cause not attributed, second not by Sherman but because of.
You were saying?
