For about 150 years, Spain's silver crossed a fifty-mile stretch of Panamanian jungle on the backs of mules and enslaved Africans. The episode describes Panama City, the fairs at Nombre de Dios and later Portobelo, and the cimarrón communities who resisted, including King Bayano and their alliance with Francis Drake.
Annual silver tonnages and the isthmus's share of Spanish silver vary by source, since smuggling left tax records incomplete. Bayano's follower counts range from a few hundred to about 1,200, and sources disagree on his African origin and exact dates.
