During the
Napoleonic Wars, the
Royal Navy rapidly and decisively seized control of the war at sea, driving French ships into protected harbours and laying heavy blockades on ports held by the
French Empire and her allies to strangle communications and overseas trade. This had a devastating effect on the French
West Indian colonies, particularly the islands of
Martinique and
Guadeloupe. With trade impossible, their economies stagnated while social upheaval and limited food supplies reduced their ability to resist invasion by the large British forces maintained in the region. In the summer of 1808, desperate messages were sent to France from the islands, prompting a succession of French efforts to supply food, reinforcements and trading opportunities during the latter part of 1808 and the first months of 1809. These efforts were entirely unsuccessful: the few ships that did safely reach the
Caribbean Sea and successfully landed supplies were all intercepted and captured on the return journey, costing the French four
frigates and numerous smaller ships by the end of February 1809. The British blockade squadrons had intercepted a number of the messages sent from the islands during 1808, and a large expeditionary force was built up on
Barbados with orders to invade and capture the French colonies as swiftly as possible. Their first target was Martinique, which was
invaded and captured during February 1809. Outlying islands were captured over the next few months and
a major French reinforcement squadron was trapped and then defeated near the
Îles des Saintes in April: the French lost a
ship of the line, and two more frigates were captured in June and July as they tried to return to France. With such heavy losses, the French took time preparing their next effort while the British were distracted by the
Reconquista in
Santo Domingo, a Spanish campaign to drive the French out of the island of
Hispaniola that was eventually concluded in July 1809 with British naval assistance. By the autumn of 1809, the British commander, Vice-Admiral
Sir Alexander Cochrane, was again developing an expeditionary force, this time aimed at Guadeloupe. He had strengthened the blockade squadron off the island's principal port
Basse-Terre, and placed heavier forces at Martinique in case they were required. Individual ships were dispersed in the approaches to the French island, ready to intercept any approaching reinforcement. Other ships operated against ships already anchored off Guadeloupe: one squadron seized the
corvette Nisus from
Deshaies on 12 December. In the months since Troude's failure, the French had only sent small supply ships to Guadeloupe, while carefully preparing a major expedition at
Nantes. Two French flûtes,
Loire, under the command of
lieutenant de vaisseau Joseph Normand-Kergré, and
Seine, under the command of
lieutenant de vaisseau Bernard Vincent, took on board large quantities of food supplies and over 200 military reinforcements each. To protect these ships two frigates were detailed to escort the convoy to Guadeloupe:
Renommée, under Commodore
Dominique Roquebert, and
Clorinde, under Captain
Jacques Saint-Cricq. The force departed on 15 November 1809 and made rapid progress across the Atlantic, avoiding all contact with British warships. Of the small ships despatched around the same time, none reached Guadeloupe; all were captured in the Western Atlantic or Caribbean by warships sent by Cochrane to patrol for approaching French reinforcements. ==Destruction of HMS
