In front of the Hornillo Pier, on the Isle of Fraile, Scottish aristocrat Hugh Pakenham Borthwick, called Don Hugo by the locals, took up residence in 1912. During World War I Borthwick worked as a British spy and alerted a liaison officer whenever a ship from Germany or from a neutral country left the pier carrying iron ore. Following the alert, the ship in question would be sunk by British submarines. After the war, Borthwick left for England where died in 1950.
