RE-ENACTMENT OF THE FALL OF THE FORTRESS OF LOUISBOURG ON THE 250th YEAR ANNIVERSARY (JULY 27, 2008)
.Siege of Louisbourg (1758)
The British government realized that with the Fortress of Louisbourg under French control, there was no way that the Royal Navy could sail up the St. Lawrence River for an attack on Quebec unmolested. After an expedition against Louisbourg in 1757 led by Lord Loudon was turned back due to a strong French naval deployment, the British under the leadership of William Pitt resolved to try again with new commanders.

Pitt assigned the duty of capturing the fortress to Major General Jeffrey Amherst. Amherst's brigadiers were Charles Lawrence, James Wolfe and Edward Whitmore, and command of naval operations was assigned to Admiral Edward Boscawen. The chief engineer was John Henry Bastide who had been present at the first siege of Louisbourg in 1745 and was chief engineer at Fort St Philip, Minorca, in 1756 when the British had surrendered the fort and island to the French after a long siege.

As they had in 1757, the French planned to defend Louisbourg by a large naval build-up. However, the French fleet sailing from Toulon was blockaded in Cartagena by a British force, and a relief force was defeated at the Battle of Cartagena. After this the French abandoned their attempt to reinforce Louisbourg from the Mediterranean, meaning there would be few ships available to actively oppose the British off Louisbourg.

British forces assembled at Halifax, Nova Scotia where army and navy units spent most of May training together as the massive invasion fleet came together. After a large gathering at the Great Pontack, on 29 May the Royal Navy fleet departed from Halifax for Louisbourg. The fleet consisted of 150 transport ships and 40 men-of-war. Housed in these ships were almost 14,000 soldiers, almost all of whom were regulars (with the exception of four companies of American rangers). The force was divided into three divisions: Red, commanded by James Wolfe, Blue, commanded by Charles Lawrence and White commanded by Edward Whitmore. On 2 June the British force anchored in Gabarus Bay, 3 miles (4.8 km) from Louisbourg.

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 defenses, such as an artillery battery, at Kennington Cove.

The Siege

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 7 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.

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.

On 21 July a mortar round from a British gun on Lighthouse Point struck a 74 gun French ship of the line, L'Entreprenant, and set it ablaze. A stiff breeze fanned the fire, and shortly after the L'Entreprenant caught fire, two other French ships had caught fire. L'Entreprenant exploded later in the day, depriving the French of the largest ship in the Louisbourg fleet.
The next major blow to French morale came on the evening of 23 July, at 10:00. A British "hot shot" set the King's Bastion on fire. The King's Bastion was the fortress headquarters and the largest building in North America in 1758. Its destruction eroded confidence and reduced morale in the French troops and their hopes to lift the British siege.
