From Encyclopedia.org: Havana The creation in 1140 of a monopolistic trading-company was an event of importance in the history of the island. English squadrons threatened the city several times in the first half of the 18th century, but it was not until 1762 than an investment, made by Admiral Sir George Pocock and the earl of Albemarle, was successful. The siege lasted from June to August and was attended by heavy loss to both besiegers and besieged. The British commanders wrung great sums from the church and the city as prize of war and price of good order.
