, showing the positions of the British and Spanish ships on 16 February On 12 February, an expedition composed of four ships of the line, two sloops and a bomb-vessel, under the command of Rear-Admiral
Henry Harvey, in , having on board his ship Lieutenant-general Sir Ralph Abercromby, as the commanding officer of the troops to be employed, quit Port-Royal, Martinique. On 14 February, the rear-admiral arrived at the port of rendezvous, the island of
Carriacou, and was there joined by another sail of the line, the
74-gun third-rate (), two frigates, three sloops, and several transports, containing the troops destined for the attack. By 15 February, the squadron and transports again set sail, running between the islands of Carriacou and Grenada. On the morning of the next day, the whole flotilla arrived off Trinidad and steered for the
Gulf of Paria. Just as the British squadron had passed through the Great Bocas channel, a Spanish squadron was discovered at anchor in
Chaguaramus Bay, consisting of the following four ships of the line and one frigate: the 84-gun
San Vincente under
Geronimo Mendoza, the 74-guns
Gallardo under
Gabriel Sororido,
Arrogante under
Raphael Benasa,
San Damaso under
Tores Jordan and the 36-gun
Santa Cecilia under
Manuel Urtesabel, all under the command of Squadron-commander
Sebastián Ruiz de Apodaca. The apparent strength of the battery on
Gaspar Grande island, mounting 20 cannon and two mortars, commanded and might have disputed, the entrance to the enemy's anchorage, caused Hardy to order the transports, under the protection of , , and , to anchor a little further up the gulf, at the distance of about five miles from the town of
Port-d'Espagne, while , , and kept under sail between the transports and Port-d'Espagne, to prevent any vessels escaping from the latter. In the meantime, the rear-admiral, with his four ships of the line, anchored, in order of battle, within random-shot of the Spanish batteries and line-of-battle ships, to be prepared in case the ships, having all their sails set and appearing to be ready for sea, should attempt during the night to escape. The British began to observe flames bursting out from one of the Spanish ships. In a short time three others were on fire and all four continued to burn with great fury until daylight. The Spanish had set the ships on fire as most of the marines and seamen were ashore.
San Damaso escaped the conflagration and, without any resistance, was captured by the boats of the British squadron. The Spaniards, meanwhile, had abandoned Gaspar Grande and soon after daylight a detachment of the
14th Regiment of Foot occupied the island. In the course of the day the remainder of the troops landed about three miles from Port of Spain, without the slightest opposition, and on the same evening, quietly entered the town itself. This led to Governor
José María Chacón offering to capitulate; on the following day, the island of Trinidad surrendered to the British arms, without an effort at defence and without any casualties. Abercromby made
Thomas Picton governor of Trinidad as a British crown colony, with a French-speaking population and Spanish laws. ==Aftermath==
