Nearly a century later, the British Royal Navy launched another invasion, capturing Guantánamo Bay in 1741 during the War of Jenkins' Ear with Spain. Edward Vernon, the British admiral who devised the scheme, saw his 4,000 occupying troops capitulate to raids by Spanish troops, and more critically, an epidemic, forcing him to withdraw his fleet to British Jamaica. In the War of the Austrian Succession, the British carried out unsuccessful attacks against Santiago de Cuba in 1741 and again in 1748. Additionally, a skirmish between British and Spanish naval squadrons occurred near Havana in 1748.
