With the surrender of Fort Desaix, British forces solidified their occupation of the island of Martinique.
The remaining shipping and military supplies were seized and the regular soldiers of the garrison taken as prisoners of war.
The militia were disbanded and Martinique became a British colony, remaining under British command until the restoration of the French monarchy in 1814, when it was returned to French control.
British losses in the campaign were heavy, with 97 killed, 365 wounded and 18 missing.
French total losses are uncertain but the garrison suffered at least 900 casualties, principally in the fighting in the central highlands on 1 and 2 February and during the siege of Fort Desaix.
Upon his return to France, Villaret's conduct was condemned by an inquiry council; he requested in vain a Court-martial to clear his name, and lived in disgrace for two years.

In Britain, both Houses of Parliament voted their thanks to Cochrane and Beckwith, who immediately began planning the invasion of Guadeloupe, executed in January 1810.
Financial and professional rewards were provided for the junior officers and enlisted men and in 1816 the battle honour Martinique was awarded to the ships and regiments involved, with the date 1809 added in 1909 to distinguish the campaign from the earlier operations of 1762 and 1794.
Four decades later the operation was among the actions recognised by a clasp attached to the Naval General Service Medal and the Military General Service Medal, awarded upon application to all British participants still living in 1847.
In France, the defeat was the subject of a court martial in December 1809, at which Villaret de Joyeuse and a number of his subordinates were stripped of their commissions, honours, and ranks for inadequately preparing for invasion, in particular for failing properly to strengthen and disperse the magazine at Fort Desaix.

There was a subsequent French effort to reach Martinique, launched in February 1809 before news of the British invasion had reached Europe.
Three ships of the line and two disarmed frigates were sent with soldiers and supplies towards the island, but learned of Villaret de Joyeuse's surrender in late March and instead took shelter in the Îles des Saintes, blockaded by Cochrane's squadron.
On 14 April, Cochrane seized the Saintes and the French fled, the three ships of the line drawing away Cochrane's forces so that the frigates could slip away and reach Guadeloupe.
During the ensuing Action of 14–17 April 1809, the French flagship Hautpoult was chased down and captured, but two ships of the line escaped and the frigates reached Guadeloupe, although neither would ever return to France.
