Spanish Empire. Just as the earlier War of Jenkins' Ear had forced the British government into a thorough review of its military, this war forced the Spanish government into undertaking a similar process. The invasions of Havana and Manilla were the catalyst for profound political and military reforms in the Spanish overseas empire. It was clear to the Spanish authorities that their regular army in Cuba could not match the strength that the British army in America could concentrate against it. It was, therefore, necessary to form a disciplined colonial militia, with adequate weapons and training, supervised by experienced officers and non-commissioned officers, with an organisation and uniforms similar to the regulars. The regular garrison of about 3,200 would be backed by a disciplined militia of eight infantry battalions and one regiment each of cavalry and dragoons, totaling 7,500 soldiers, with many of the officers from prominent Cuban families. Havana and Manila were returned to Spain as a result of the Treaty of Paris signed in February 1763, but the British occupation lasted until two months later, when a newly appointed Captain General of Cuba, Alejandro O'Reilly, arrived to re-establish Spanish rule. Spain agreed to cede Florida and Menorca to Great Britain. The loss of Florida and the Spanish acceptance of British occupation of the Miskito Coast heightened Cuba's value as the first line of defence for the Spanish South American colonies. Spain received French Louisiana as a payment for intervening in the war on the side of the French and as compensation for having lost Florida. Exhibition El Morro once housed a school for lighthouse keepers. There was actually a watchtower here until the British blew it up during their successful siege in 1762. The Faro Castillo del Morro lighthouse was added in 1846. The cannons around the fort are now badly rusted, but the walls are well preserved. The fort has central barracks up to four stories high. A small underwater archeology exhibition is also located here. Noteworthy are the old latrines and their chute into the sea, as are the two sets of doors and the drawbridge mechanism. The current harbor master's office is still housed in the fortress. A plaque dedicated by the ambassador of the United Kingdom commemorates the 1762 siege, and a small memorial is located between two strong powder rooms in the northeast bastion. A small turret at the end of the wall
