The Battle of Nagapatam was an indecisive naval battle on 3 August 1758 during the Seven Years' War. A British squadron under Vice-Admiral George Pocock fought a French squadron under Comte d'Aché off the Carnatic coast of India near Negapatam in the second of three battles fought between the two admirals during the war. Both squadrons suffered heavy damage during the short but fierce engagement, with d'Ache's flagship Zodiaque catching fire and d'Ache himself severely wounded. He would spend the remainder of the year recovering in Mauritius.[1]
