A brass pocket watch pulled from the Caribbean seabed in the 1960s has hands frozen at 11:43, the minute on June 7, 1692 when an earthquake sent much of Port Royal, Jamaica, sliding into the sea.

We cover the English capture of Jamaica in 1655, Governor Edward D'Oyley's 1657 invitation to the Brethren of the Coast, the letter-of-marque system that turned piracy into forced trade, Henry Morgan's 75,000-pound Portobello raid, a town of nearly 10,000 people on 51 acres with a drinking house for every 10 residents, the anti-piracy crackdown and Gallows Point, soil liquefaction under heavy brick buildings, and the Texas A&M excavation that recovered untouched tavern artifacts.
