Charleston Time Machine is a history program tied to one city and the Lowcountry around it, from Nic Butler, a historian at the Charleston County Public Library. Episodes open with a brief introduction from Butler and then settle into a narrated story full of names, dates and the physical details of a colonial port. It sounds less like a conversation about the past than a guided reading of the records. The episodes in view follow the unraveling of royal authority in South Carolina. A connected run tracks Lord William Campbell, a young British naval captain who sailed into Charleston Harbor in 1763 and married a local heiress, Sarah Izard, a few weeks later. The narration names slavery plainly, noting that the marriage tied Campbell to the colony's slave-owning community. The story follows the couple back and forth across the Atlantic, through Campbell's time as governor of Nova Scotia and a stay in Charleston in 1772, up to his arrival in June 1775 as the colony's new royal governor. On the surface his welcome is polite. Underneath, it is seditious. Butler builds the tension from small facts, like the Royal Navy station ship Tamar, which had sat in Rebellion Road for nearly three months and fired no salute when the governor's ship came in. Earlier friction gets its due as well, including Governor Boone's clashes with the elected assembly and with a firebrand named Christopher Gadsden. The same thread reaches Samson Waldron, an enslaved mariner whose piloting skills the warship Scorpion needed to get out of the harbor. Royal Navy officers negotiated with him quietly, and the prospect of freedom in the king's service kept him aboard. One of the sharpest details is a single ledger line: the purser entered him in the muster book as a 'pilot extraordinary' and spelled his name by ear. The same eye for the telling document drives 'Episode 313: The 1775 Debut of the South Carolina Flag', which comes back to a subject Butler covered in a 2021 program, this time with new evidence. The logbooks of two British naval officers describe the rebel colors raised over Fort Johnson as 'a white crescent in a green field'. Butler lays out the problem plainly: Colonel Moultrie's memoir describes a blue flag, and Butler talks through his own doubts, even suggesting colorblindness as one explanation. The real reward is hearing a historian weigh a surprising source against a trusted one. Every episode in view closes the same way, thanking 'my friends' and promising to see listeners 'in the future', which suits a show with this name. Illustrated transcripts and a newsletter are available at ccpl.org. The flag episode works on its own as a starting point, while the two-part Campbell and Izard installments set up the longer story of 1775.
