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 of five warships and 4,000 troops set out from Portsmouth to capture Cuba. The British arrived on 6 June, and by August had Havana under siege. When Havana surrendered, the admiral of the British fleet, George Keppel, the 3rd Earl of Albemarle, entered the city as a new colonial governor and took control of the whole western part of the island. The arrival of the British immediately opened up trade with their North American and Caribbean colonies, causing a rapid transformation of Cuban society.
