In 1762, British forces mobilized more than 230 ships and 26,000 soldiers, sailors, and enslaved Africans to attack Havana, one of the wealthiest and most populous ports in the Americas. They met fierce resistance. Spanish soldiers and local militias in Cuba, along with enslaved Africans who were promised freedom, held off the enemy for six suspenseful weeks. In the end, the British prevailed, but more lives were lost in the invasion and subsequent eleven-month British occupation of Havana than during the entire Seven Years' War in North America.
