In February 1782, Menorca fell to a combined French and Spanish fleet and with the capture of the Floridas, these constituted significant successes for Spain. However, the largest effort was devoted to the Great Siege of Gibraltar which after three years had made little progress despite enormous expenditures of both money and men. The imposition of heavy taxes and 'voluntary' donations to pay for the war caused unrest in much of the Spanish Empire, including the 1781 Revolt of the Comuneros in New Granada. In the end, the Spanish siege of Gibraltar absorbed British resources that might otherwise have been used in America but left them with little to show for their investment.
