Spain learned of the French expedition to Florida through its spies at ports on the Atlantic coast of France. Philip II was alarmed when Dr. Gabriel de Enveja reported that Jean Ribault had been appointed as "Captain-General and Viceroy of New France". He also said that a large expedition of ships, soldiers and supplies was being fitted at Dieppe for a voyage to Florida: it was to have more than 500 arquebusiers, and many dismounted bronze cannons were loaded aboard the vessels.
