The Battle of Cartagena took place on 28 February 1758 off the Spanish port of Cartagena during the Seven Years' War. A British fleet under Henry Osborn, which had blockaded a French fleet in Cartagena, attacked and defeated a French squadron under Michel-Ange Duquesne de Menneville coming to their assistance. The interception of de Menneville's squadron ensured that only limited assistance would come to the French fortress of Louisbourg in North America, which was under a British siege and fell later that year.
