Fort Royal was the headquarters station of the French in the West Indies. It was situated at the head of a deep bay, Cul de Sac Royal as it was called. The place was strongly fortified, and was the great arsenal and dockyard of France across the Atlantic. For a hundred years past and more French fleets and squadrons had fitted there for war, and had put in to repair after battle. Thence Du Casse had sailed to fight Benbow. From there, as we have seen, De Grasse put out to meet his fate off the 'Saints' at the hands of Rodney. Two fortified positions of considerable strength and with heavy cannon, besides outlying redoubts and batteries, defended the town of Fort Royal; one position fronting inland, the other facing towards the sea. Against the former, Fort Bourbon, an entrenched work set on high ground at the back of the town of Fort Royal, the main force of our soldiers was to operate, attacking with a siege train of heavy guns and mortars and opening zigzags and parallels in the orthodox way. Fort Louis on the sea front, blocking the entrance to the _carenage_, or man-of-war harbour, and the dockyard, was to be attacked by the Naval Brigade, assisted by a number of grenadier and light infantry companies, with siege batteries made up of ships' 24-pounders. At the entrance to Fort Royal Bay, to 'keep the ring,' as it were, rode the big two-deckers and frigates of the fleet. The bombardment began on the 7th of March and lasted ten days, during which time the enemy resisted stoutly. Their sorties were, however, beaten back, and by the 16th of the month the advanced batteries of the second parallel had been pushed forward to within 500 yards of Fort Bourbon. The sappers and miners had in the same time got nearer still to Fort Louis. As yet though no date had been fixed for the assault.
