The Queen declared that all written accounts of Drake's voyages were to become the Queen's secrets of the Realm, and Drake and the other participants of his voyages on the pain of death sworn to their secrecy; she intended to keep Drake's activities away from the eyes of rival Spain. Drake presented the Queen with a jewel token commemorating the circumnavigation. Taken as a prize off the Pacific coast of Mexico, it was made of enamelled gold and bore an African diamond and a ship with an ebony hull.
