Charles Hector, comte D'Estaing led French forces against the British-held West Indies island of Grenada.

The French forces assaulted the British fortifications on Hospital Hill, overlooking the island's capital, Saint George's.

On 5 July, French forces re-embarked when word arrived that a British fleet under Admiral John Byron was approaching.

[9] Byron departed St. Lucia on 6 June in order to provide escort services to British merchant ships gathering at St. Kitts for a convoy to Europe, leaving d'Estaing free to act.

D'Estaing and the French governor-general at Martinique, François Claude Amour, marquis de Bouillé, seized the opportunity to begin a series of operations against nearby British possessions.

He had hoped to capture Barbados, a key British possession, but after making no progress against the prevailing easterly trade winds, he turned his attention instead to Grenada.

He made repeated requests for support to Admiral Byron and the British commander at St. Kitts but was told that Saint Vincent was the principal French interest.

Macartney found d'Estaing's proposed articles "not merely unprecedented and humiliating, but so ensnaring and uncertain in their nature, extent, and aim that they might at any time supply a pretext for taking away the lives, together with the fortunes, of the capitulants.

[22] Admiral Byron had been alerted to the capture of Saint Vincent on 1 July and was en route with a force to retake it when he learned of the attack on Grenada.

[24] There were no further major actions in the West Indies before d'Estaing sailed north and led an unsuccessful siege of British-held Savannah, Georgia in September.

[26] Playwright and actor Pierre-Germain Parisau wrote Veni, Vidi, Vici, ou La Prise de Grenade containing a re-enactment of the capture.

[19] Both Grenada and Saint Vincent remained in French hands until the end of the war, when they were returned to Britain under the terms of the 1783 Treaty of Paris.

[28] The rule of the comte de Durat, who was appointed governor by d'Estaing, was reported by British residents to be harsh and oppressive.

[29] After the British resumed control, they cracked down on the predominantly Roman Catholic French-speaking population, leading to discontent and an exodus of French Grenadians to Trinidad.

[30] These religious and cultural divisions in Grenadian society contributed to the rise of local resistance which culminated in the nearly-successful Fédon Rebellion in 1795–96.
