Fort Desaix is a Vauban fort and one of four forts that protect Fort-de-France, the capital of Martinique. The fort was built from 1768 to 1772 and sits on a hill, Morne Garnier, overlooking what was then Fort Royal.[1] Fort Desaix was built in response to the successful British attack on Fort Royal in 1762 and was intended to prevent any future attacker from using Morne Garnier to site cannon that could then bombard Fort Royal from above.
