Cochrane's fleet sailed from Carlisle Bay on 28 January, arriving off Martinique early on 30 January.
The force was then divided, one squadron anchoring off Sainte-Luce on the southern coast and another off Le Robert on the northern.
The invasion began the same morning, 3,000 soldiers going ashore at Sainte-Luce under the command of Major-General Frederick Maitland, supervised by Captain William Charles Fahie, while 6,500 landed at Le Robert under Major-General Sir George Prevost, supervised by Captain Philip Beaver.
Beckwith remained on Cochrane's flagship HMS Neptune, to direct the campaign from offshore.
A third force, under a Major Henderson and consisting entirely of 600 soldiers from the Royal York Rangers, landed at Cape Salomon near Les Anses-d'Arlet on the southwestern peninsula to secure the entrance to Fort-de-France Bay.

During the first day of the invasion, the two main forces made rapid progress inland, the militia troops sent against them retreating and deserting without offering resistance.
Serious opposition to the British advance did not begin until 1 February, when French defenders on the heights of Desfourneaux and Surirey were attacked by Prevost's troops, under the direct command of Brigadier-General Daniel Hoghton.
Fighting was fierce throughout the next two days, as the outnumbered French used the fortified high ground to hold back a series of frontal assaults.
The British lost 84 killed and 334 wounded to French losses of over 700 casualties, and by 3 February the French had been forced back, withdrawing to Fort Desaix near the capital.
Progress was also made at Cape Salomon, where the appearance of British troops panicked the French defenders into burning the naval brig Carnation and retreating to the small island, Ilot aux Ramiers, offshore.
Henderson's men, assisted by a naval brigade under Captain George Cockburn, set up batteries on the coast and by 4 February had bombarded the island into surrender, opening the principal harbour of Martinique to naval attack.

A small naval squadron, consisting of HMS Aeolus, HMS Cleopatra and the brig HMS Recruit, advanced into Fort-de-France Bay on 5 February.
This advance spread panic among the French militia defending the bay and Amphitrite and the other shipping anchored there were set on fire and destroyed, while the forts in the southern part of the island were abandoned.
On 8 February, Maitland's force, which had not yet fired a shot, arrived on the western side of Fort Desaix and laid siege to it.
Minor detachments spread across the remainder of the island: Lieutenant-Colonel Edward Barnes captured Saint-Pierre and another force occupied Fort-de-France and seized the corvette Diligente in the harbour.
By 10 February, when Prevost's force linked up with Maitland's, Fort Desaix was the only remaining point of resistance.

For nine days, the British soldiers and sailors of the expeditionary force constructed gun batteries and trenches around the fort, bringing ashore large quantities of supplies and equipment in readiness for a lengthy siege.
At 16:30 on 19 February the preparations were complete and the bombardment began, 14 heavy cannon and 28 mortars beginning a continuous attack on the fort which lasted for the next four days.
French casualties in the overcrowded fort were severe, with 200 men killed or wounded.
British casualties were minimal, with five killed and 11 wounded, principally in an explosion in an ammunition tent manned by sailors from HMS Amaranthe.
At 12:00 on 23 February, Villaret de Joyeuse's trumpeter was sent to the British camp with a message proposing surrender terms.
These were unacceptable to Beckwith and the bombardment resumed at 22:00, continuing until 09:00 the following morning when three white flags were raised over the fort and the French admiral surrendered unconditionally.
The bombardment had cracked the roof of the fort's magazine, and there were fears that further shelling might have ignited the gunpowder and destroyed the building completely.
