siege of Louisbourg (1758)

The siege of Louisbourg was a pivotal operation of the Seven Years' War (known in the United States as the French and Indian War) in 1758 that ended the French colonial era in Atlantic Canada and led to the subsequent British campaign to capture Quebec in 1759 and the remainder of French North America the following year.

Background

The British government realized that with the Fortress of Louisbourg under French control, the Royal Navy could not sail up the St. Lawrence River unmolested for an attack on Quebec. 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 task of capturing the fortress to Major General Jeffery 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 means of a large naval build-up. However, the British blockaded the French fleet sailing from Toulon when it arrived in Cartagena, and defeated a French relief force at the Battle of Cartagena.

The French consequently abandoned their attempt to reinforce Louisbourg from the Mediterranean, and only 11 ships were available to oppose the British off Louisbourg. Most of the cannons and men were moved inside the fort and five ships (''Appolon'', ''Fidèle'', ''Chèvre'', ''Biche'', ''Diane'') were sunk to block the entrance to the harbour.
On 9 July, ''Echo'' tried to slip out of the harbour under the cover of a dense fog, but was intercepted and seized by
HMS ''Scarborough'' and HMS ''Junon''. This left the French with only five half-empty ships in the harbour : ''Célèbre'' (64), ''Entreprenant'' (74), ''Capricieux'' (64), ''Prudent'' (74) and ''Bienfaisant'' (64).

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.

Order of battle

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, 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 defended by some 2,000 French troops, along with other defences, such as an artillery battery, at Kennington Cove.

French forces

Ground troops

The French garrison based within the Fortress of Louisbourg was commanded by Augustin de Boschenry, Chevalier de Drucour. Between 1755 and the time of the siege, the French garrison expanded from 1,200 troops to around 6,000 troops. Troops forming the garrison included:
* 2nd Battalion, Regiment of Artois — ''2éme Bataillon du Régiment d'Artois'' (520 Troops)
* 2nd Battalion, Regiment of Burgundy — ''2éme Bataillon du Régiment de Bourgogne'' (520 Troops)

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 defences 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 defences 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 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.

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.

Naval action

Most historians regard the British actions of 25 July as the "straw that broke the camel's back". Using a thick fog as cover, Admiral Boscawen sent a cutting-out party to destroy the last two French ships in the harbour. The British raiders eliminated these two French ships of the line, capturing and burning ''Prudent'', thus clearing the way for the Royal Navy to enter the harbour. James Cook, who later became famous as an explorer, took part in this operation and recorded it in his ship's log book.

Capitulation

On 26 July the French surrendered. Having fought a spirited defence, the French expected to be accorded the honours of war, as they had given to the surrendering British at the Battle of Minorca. However, Amherst refused, tales of the atrocities supposedly committed by France's native allies at the surrender of Fort Oswego and Fort William Henry probably fresh in his mind. The defenders of Louisbourg were ordered to surrender all of their arms, equipment and flags. These actions outraged Drucour, but because the safety of the non-combatant inhabitants of Louisbourg depended upon him he reluctantly accepted the terms of surrender. The Cambis regiment refused to honour the terms of surrender, breaking its muskets and burning its regimental flags rather than hand them over to the British victors.Fowler, p. 171 Brigadier-General Whitmore was appointed the new Governor of Louisbourg, and remained there with four regiments.

Aftermath

Louisbourg had held out long enough to prevent an attack on Quebec in 1758. However the fall of the fortress led to the loss of French territory across Atlantic Canada. From Louisbourg, British forces spent the remainder of the year routing French forces and occupying French settlements in what is today New Brunswick, Prince Edward Island and Newfoundland. The second wave of the Acadian expulsion began. The British engaged in the St. John River Campaign, the Cape Sable Campaign, the Petitcodiac River Campaign, the Ile Saint-Jean Campaign, and the removal of Acadians in the Gulf of St. Lawrence Campaign (1758).

The loss of Louisbourg deprived New France of naval protection, opening the Saint Lawrence to attack. Louisbourg was used in 1759 as the staging point for General Wolfe's famous siege of Quebec ending French rule in North America. Following the surrender of Quebec, British forces and engineers set about methodically destroying the fortress with explosives, ensuring that it could not return to French possession a second time in any eventual peace treaty. By 1760, the entire fortress was reduced to mounds of rubble. In 1763 the Treaty of Paris saw France formally cede Canada, including Cape Breton Island, to the British. In 1768 the last of the British garrison departed along with most of the remaining civilian inhabitants.Chartrand p.92
