The Seven Years' War, which erupted in 1754 across three continents, eventually arrived in the Spanish Caribbean. Spain's alliance with the French pitched them into direct conflict with the British, and in 1762, a British expedition consisting of dozens of ships and thousands of troops set out from Portsmouth to capture Cuba. The British arrived on 6 June, and by August, had placed Havana under siege. When Havana surrendered, the admiral of the British fleet, George Pocock and the commander of the land forces George Keppel, the 3rd Earl of Albemarle, entered the city, and took control of the western part of the island. The British immediately opened up trade with their North American and Caribbean colonies, causing a rapid transformation of Cuban society.
