Earlier that summer, the government of Spain successfully argued that, under the terms of international Sovereign Immunity, it never abandoned or otherwise relinquished its ownership of the Nuestra Senora de las Mercedes, which sunk during a sea battle with the British Navy in 1804.

Like every grand tale of shipwreck and lost treasure, the story about the Polluce has it all. A paddlewheel steamboat shipwrecked in 1841, it is the centrepiece of a drama spanning more than one and a half centuries and has all the necessary ingredients: drama and tragedy, greed and crime, passion and politics. And it is still ongoing. Polluce is about to be excavated once more as this story goes to press.
