In 1803
Napoleon Bonaparte appointed him to command the French forces in the Indian Ocean and to convey the new Captain-General of French India,
Charles Mathieu Isidore Decaen to
Pondicherry. Flying his flag aboard the 74-gun-ship
Marengo, Linois left Brest on 6 March with only three frigates in company; much of the French fleet still being occupied at Saint-Domingue. On arrival however, the British forces there, under
Arthur Wellesley, refused to leave and Linois was obliged to detour to the
Ile-de-France. Linois received news that the war had resumed when he was joined by the 22-gun
corvette,
Berceau in September. Arriving at Batavia on 10 December, Linois was appraised of a British convoy returning from China. After dropping off the soldiers and adding the 16 gun brig-corvette,
Adventurier, to his force, set sail on 28 December. The
Battle of Pulo Aura occurred on 14 February 1804 when Linois' squadron encountered the British China Fleet. Although lightly armed, the British merchant ships outnumbered Linois' forces and manoeuvred as though preparing to defend themselves. Some of the larger
indiamen, with gun ports painted on and flying naval ensigns, formed a mock
line of battle. With these tactics, the convoy commodore,
Nathaniel Dance, fooled Linois into believing that the British fleet was defended by naval escorts and the French retired without attacking the virtually defenceless British. On the return journey, Linois' ships took another prize, and arrived at Ile de France on 1 November, to find
Belle Poule with a capture of her own. In May 1805, while
Atalante and
Semilante were attending to other duties, Linois took
Marengo and
Belle Poule into the
South Atlantic. This cruise was not productive and, after visiting
Cape Town, the squadron patrolled the east coast of Africa and the
Red Sea. This also proved fruitless and it was not until 11 July, following a decision to search the sea lanes between Cape Town and Ceylon that any enemy vessels were encountered. It was off the coast of Ceylon they fell in with two unprotected merchant ships, one of which was driven onto the shore and the other, the east indiaman
Brunswick, captured. With only two ships at his disposal, Linois' options had dwindled to chasing lone ships and unarmed convoys. Realising his best chance of catching them was to scout around
choke points, in December, his small squadron sailed for the popular British stop over of
St Helena. On 29 January 1806, Linois learned from an American ship of the British capture of
Cape Town. With the last accessible port closed, Linois could only turn around and head for home. In the
action of 13 March 1806, the 90-gun
HMS London, the 80-gun
HMS Foudroyant and the 38-gun frigate
HMS Amazon, were sailing some miles ahead of their compatriots when, at 03:00, Linois' ships were spotted. The three British ships immediately gave chase and by 05:30,
London had overhauled and begun an exchange with both French ships. By 06:00 Linois realised that he was unable to win the battle and attempted to move off, issuing orders for
Belle Poule to do likewise. Both
Marengo and
Belle Poule had been severely battered in the rigging and were finding it increasingly difficult to manoeuvre.
Marengo could not avoid ''London's
continuing fire or the cannonade from Amazon
as she passed in pursuit of Belle Poule
. London
too had been heavily damaged and was beginning to drift astern but the appearance of Foudroyant
, and HMS Repulse
at 10:25 and HMS Ramillies'' at 11:00, left the French ships with no option but to surrender. ==Later life and death==
