PROBLEM: Question: What is the current population of the first location mentioned that Spain recovered in military campaigns during the war? Passage:The rivalry with Britain also led him to support the American revolutionaries in their War of Independence despite his misgivings about the example it would set for the Spanish Colonies. During the war, Spain recovered Menorca and British West Florida in military campaigns, but failed to regain Gibraltar. Spanish military operations in West Florida and on the Mississippi River helped the Thirteen Colonies secure their southern and western frontiers from British attack. The capture of Nassau in the Bahamas enabled Spain to also recover East Florida during peace negotiations. The Treaty of Paris of 1783 confirmed the recovery of the Floridas and Menorca, and restricted the actions of British commercial interests in Central America.
