When the
Artésien reached the
mouth of the harbour, she spotted the British fleet at anchor, and signalled Suffren that the enemy was in sight. Suffren, assuming (correctly) that the fleet had men ashore and would be in some disarray, immediately gave orders to attack, leading the way with his flagship, the
Héros. Johnstone, who was in the process of ordering ship manoeuvres to separate ships that had drifted too close to one another when the French squadron was spotted, had to scramble to prepare the fleet for battle. Suffren's orders were for his line to anchor before the British fleet and open fire. This he did with
Héros, taking on and , the two largest British ships.
Annibal soon came to his aid, and eventually drew most of the fire.
Artésien, whose captain was killed early in the engagement, captured the East Indiaman in the confusion, and then a breeze blew her away from the action. The
Vengeur passed along the anchored British fleet exchanging broadsides but never anchored herself and passed out of the action, while the
Sphinx also failed to anchor, and only contributed minimally to the action. Suffren, with the advantage of surprise, maintained the action with the two anchored ships for ninety minutes until damage (
Annibal lost two of three masts) led him to signal a retreat while maintaining fire.
Annibal lost her third mast on her way out of the harbour, and was slow to follow
Héros. The French captured the
East Indiamen Hinchinbrook and
Fortitude, the fireship
Infernal and the victualer
Edward. The British however recaptured them all over the next few days. ==Aftermath==
