Spain Declares War on Britain
On 16 June 1779 Spain declared war on Britain, joining France in a conflict that now truly encircled the British Empire. Spain's entry was not driven by sympathy for American republican ideals — Madrid feared that successful colonial revolt against a European power might inspire its own American subjects — but by the opportunity to recover Gibraltar, Minorca, Florida, and other territories lost in previous wars. The Convention of Aranjuez (April 1779) secretly bound France and Spain to continue fighting until Gibraltar was recovered. Spain's entry dramatically widened the war. The siege of Gibraltar, which began in 1779 and lasted until 1783, tied down a substantial British military force. Spain also recaptured West Florida from Britain by 1781 and attacked British positions in the Caribbean and Central America. The combination of France, Spain, and the Netherlands (which entered the war in December 1780) left Britain fighting a global coalition on every ocean while simultaneously suppressing rebellion in North America. For the American cause, Spanish entry was valuable primarily as a strategic distraction: Spain's fleet, combined with France's, gave the coalition clear naval superiority in Atlantic and Caribbean waters. It was this combined naval power that made the Yorktown campaign possible in 1781 — the French fleet under de Grasse that blocked British relief came from operations coordinated with the Franco-Spanish alliance. Spain never formally allied with the United States, but its entry into the war helped seal British defeat.
