From the July 2, 2017, Charleston (SC) Post & Courier "Winning the 'battle' of Fort Bull: Civil War site protected from West Ashley waterline path" by Bo Peterson.
Fort Bull consists of earthen berms back in the woods on private land and was in danger of partly being destroyed by the laying of water pipes. It was dug by Confederate soldiers neat today's Bees Ferry Road and was part of the massive defensive defenses of Charleston, S.C., during the war.
It was designed by General Beauregard and even Robert E. lee had a part in its early design before he took command of the Army of Northern Virginia. Over 200 defenses were constructed during the war in Charleston County. Most like Fort Bull were vacant most of the time, but could be easily defended in case of Union attack.
Persons interested in preserving history caused the Charleston Water System, which was laying pipe in the area to swing around the fort's remains.
