The Battle of Carthagena was an attempted invasion of Carthagena in Spanish America by British and colonial American forces in 1741. When England was preparing to send a force against the Spanish West Indies, the colonies north of Carolina were summoned to contribute four battalions to the armament. The requisition was generously complied with. But the expedition, led by Admiral Vernon, against Carthagena was anything but successful, though it was composed of twenty-nine ships and 12000 land troops. The sailors and soldiers quickly fell ill with the fever. Only the outer fortifications were demolished; then the allies were obliged to retire. Research Battle of Carthagena
