<P> The French commander (and governor of Île - Royale (New France), the Chevalier de Drucour, had at his disposal some 3,500 regulars as well as approximately 3,500 marines and sailors from the French warships in the harbour . However, unlike the previous year, the French navy was unable to assemble in significant numbers, leaving the French squadron at Louisbourg outnumbered five to one by the British fleet . Drucour ordered trenches to be prepared and manned by some 2,000 French troops, along with other defences, such as an artillery battery, at Kennington Cove . </P> <P> Weather conditions in the first week of June made any landing impossible and the British were only able to mount a bombardment of the improvised shore defenses of Gabarus Bay from a frigate . However, conditions improved, and at daybreak on 8 June Amherst launched his assault using a flotilla of large boats, organized in seven divisions, each commanded by one of his brigadiers . French defenses were initially successful and after heavy losses, Wolfe ordered a retreat . However, at the last minute, a boatload of light infantry in Wolfe's division (i.e., members of Rogers Rangers) found a rocky inlet protected from French fire and secured a beachhead . Wolfe redirected the rest of his division to follow . Outflanked, the French retreated rapidly back to their fortress . </P> <P> Continuing heavy seas and the difficulty inherent to moving siege equipment over boggy terrain delayed the commencement of the formal siege . In the meantime, Wolfe was sent with 1,220 picked men around the harbour to seize Lighthouse Point, which dominated the harbour entrance . This he did on 12 June . After eleven days, on 19 June, the British artillery batteries were in position and the orders were given to open fire on the French . The British battery consisted of seventy cannons and mortars of all sizes . Within hours, the guns had destroyed walls and damaged several buildings . </P> <P> On 21 July a mortar round from a British gun on Lighthouse Point struck a 64 - gun French ship of the line, Le Célèbre, and set it ablaze . A stiff breeze fanned the fire, and shortly after Le Célèbre caught fire, two other French ships, L'Entreprenant and Le Capricieux, had also caught fire . L'Entreprenant sank later in the day, depriving the French of the largest ship in the Louisbourg fleet . </P>
