The 1780 Siege of Charleston erased the Continental Army in the South and remains one of the biggest blind spots in the popular story of the American Revolution. This episode explains why the British, stalled in the North after Saratoga and facing France and Spain, pivoted south on the belief that hidden loyalists would rise up, and how the Philipsburg Proclamation offered freedom to people enslaved by Patriots who reached British lines.

We break down the siege as an engineering problem: Sir Henry Clinton’s slow approach from Simmons Island, Commodore Abraham Whipple scuttling his own ships in the Cooper River, zigzag siege trenches, and red-hot heated shot fired into the city. We also cover the civilian leaders who blocked General Benjamin Lincoln’s escape, the deadly magazine explosion after the surrender, and how Washington repaid the denial of the honors of war at Yorktown.
