They then perpetrated one of piracy's greatest exploits: the capture of the Portuguese great galleon "Nossa Senhora do Cabo" ("Our Lady of the Cape") or "Virgem Do Cabo" ("The Virgin of the Cape"), which was loaded full of treasures belonging to the Bishop of Goa, also called the Patriarch of the East Indies, and the Viceroy of Portugal, who were both on board returning home to Lisbon. The pirates were able to board the vessel without firing a single broadside because the "Cabo" had been damaged in a storm; to avoid capsizing the crew had dumped all 72 cannons overboard, then anchored off Réunion island to undergo repairs. (This incident would later be used by Robert Louis Stevenson in his novel "Treasure Island", in which the galleon is referred to as "The Viceroy of the Indies" in the account given by his famed fictional character Long John Silver).
