La Esmeralda is a Chilean Naval ship known to be a site of torture and detention during the dictatorship. It was docked in the port of Valparaiso, Chile then sent to tour around the world. On Friday morning, June 21, 1974, La Esmeralda was set to dock at the Oakland Naval Supply Depot. Movement activists attempted to block the dock, and hung a "Junta No" banner from the Golden Gate Bridge in protest. In solidarity, the International Longshore and Warehouse Union obstructed the ship from entering the harbor.
