In the morning of 18 December, a French convoy under
Joseph de Flotte, which had departed Marseille in October and was bound for Martinique, arrived in Saint Lucia channel, the body of water between the islands of Saint Lucia and Martinique. The convoy brought supplies for the French colonies of the Caribbeans and for the division under Lamotte, as well as diplomat
Gérard de Rayneval. It comprised 26 transports, escorted by the lone 34-gun frigate
Aurore. Around 0800, , which was stationed in Saint Lucia channel, gave a signal indicating the arrival of an unknown fleet. Parker immediately scrambled, and managed to get five
ships of the line and a 50-gun
frigate out to meet the arriving fleet. Shortly thereafter, the French observation post of
Les Anses-d'Arlet signaled the arrival of Flotte's convoy, as well as 15 British warships chasing them. Flotte sailed his ships close to shore, hoping that the shallow waters would deter the British warships from approaching, and
Aurore fell back to start a rear-guard action as to delay Hyde Parker's squadron, and alert the French forces of Martinique. The lead ships of the convoy passed Les Anses-d'Arlet around 1400. Lamotte then scrambled his ships to cover the retreat of the convoy, mustering reinforcements for his crew from the crews of the ships under repairs, as well as volunteers from the population. Lamotte left the anchorage at
Fort Royal with his flagship, the
74-gun Annibal. As his arrival was to the windward, he was able to cover the arrival of the remaining convoy ships. The British fleet, with in the lead, began beating against the wind to closing with the French fleet. By 1700,
Conqueror came with the range of
Annibal guns, and battle was engaged between those two.
Annibal found herself facing seven British ships for half an hour, before the
64-gun Vengeur and
Réfléchi joined her. By that time, the 15 British ships were also engaged. The reinforced French crew allowed Lamotte's ships to sustain an especially high rate of fire,
Annibal in particular firing alternatively from both broadsides as she turned to face the British from both sides. By the time evening arrived, had also come within range, but the action had worked its way toward shoals near Fort Royal. The coastal defences at
Pointe des Nègres and
Gros Îlet started firing of the British. Parker finally called his fleet off at 1845, but one last broadside from the French fleet took the life of
Conqueror captain,
Walter Griffith. == Aftermath ==
