Despite the Spanish attempt to regain Gibraltar at the negotiating table, they ended up merely retaining Minorca and territories in Florida, though for the Spanish this was of little or no value. An attempt to exchange Puerto Rico for Gibraltar collapsed, as it would have brought too much competition for Jamaican products into the protected British market. They ceded West Florida to the Spanish in addition to the East Florida that Spain had conquered at Mobile and Pensacola. At the Peace of Paris in September 1783, the Anglo-Spanish Treaty of Versailles left Gibraltar with the British.
