Suffren was in the process of forming his battle line around 3:00 pm when a
squall took down the main and mizzen top masts of
Ajax, under
Bouvet-Précourt, forcing her to drop out of his line. When the squall calmed, the breeze was to Hughes's advantage, so he sailed from his anchorage at the harbour of Negapatam. The two fleets spent the night anchored two cannonshots apart. The next morning, Suffren was infuriated to learn that repairs had not been made to
Ajax, and that her captain wanted to retreat. Given that battle was imminent, Suffren refused. He then ordered his line to bear down on the British line for close action. As they began to move,
Ajax stood away and did not join the action. At 9:30 am on 6 July, the fleets opened fire on each other, first at long range.
Flamand engaged
Hero and
Exeter,
Annibal engaged
Isis,
Sévère faced
Burford, and
Brillant opposed
Sultan while the two flagships,
Héros and
Superb, did battle with each other. The remainder of the British line was not able to directly line up against the French, resulting in an angle in their line where
Sphinx and
Monarca battled that minimized the action between the ships at the end of the line.
Flamand took significant damage, but was able to return the favour to its opponents.
Brillant began to suffer under the fire of
Sultan, but Suffren managed to detach from
Héros to come to her rescue. The battle proceeded with vigour until about 1:00 pm, when the wind suddenly changed, throwing both lines into confusion. With the wind head-on to the two parallel lines of ships, some ships turned to starboard and some to port. The majority turned away from the engagement, but six ships, four British and two French, turned in towards one another. The four British ships were the fourth, fifth, eighth and tenth in line, respectively
Burford,
Sultan,
Worcester and
Eagle; the two French were
Sévère (third in line) and towards the rear of the line
Brillant, which had been dismasted by this stage.
Sévère was engaged by
Sultan and "two other ships," and escaped through the arrival of Suffren in his flagship and the filling of her sails as she fell off to starboard, while
Brillant was fired on by
Worcester and
Eagle, and was also rescued by the approach of Suffren's ship, though not before the loss of over a third of her complement dead or wounded.
