The Battle of Sadras was the first of five largely indecisive naval battles fought between a British fleet (under Vice-Admiral Sir Edward Hughes) and a French fleet (under Admiral Pierre Suffren) off the east coast of India during the Anglo-French War. Fought on 17 February 1782 near present-day Kalpakkam, the battle was tactically indecisive, but the British fleet suffered the most damage. Under Suffren's protection, French troop transports were able to land at Porto Novo, present-day Parangipettai.
