On the stillest nights, at nine o’clock, Major Anderson could hear the great bells in the distant witch-cap spire of St. Michael’s Church, bastion of Charleston society where planters displayed rank by purchasing pews. It stood adjacent to Ryan’s Slave Mart, and each night rang the “negro curfew” to alert the city’s enslaved and free Blacks that they had thirty minutes to return to their quarters, lest the nightly “slave patrol” find them and lock them in the guard house until morning.
