Montreal campaign


The Montreal campaign, also known as the fall of Montreal, was a British three-pronged offensive against Montreal which took place from July 2 to 8 September 1760 during the French and Indian War as part of the global Seven Years' War. The campaign, pitted against an outnumbered and outsupplied French army, led to the capitulation and occupation of Montreal, the largest remaining city in French Canada.
Under the overall direction of Jeffery Amherst, British forces numbering around 18,000 men converged on Montreal starting in July from three separate directions. One under Amherst moved in from Lake Ontario, the other under James Murray moved from Québec and the third under William Haviland moved from Fort Crown Point. After capturing French positions and outposts along the way all three forces met up and surrounded Montreal. Many Canadiens deserted or surrendered their arms to British forces while the native allies of the French began to negotiate peace treaties and alliances with the British.
The French military commander in the region, François Gaston de Lévis, was resolved to make a last stand in the city despite the overwhelming numerical inferiority of his troops. He was however overruled by Pierre de Rigaud, the civilian Governor of French Canada who persuaded him to surrender. Lévis attempted to negotiate a surrender with the honours of war, but the British rejected such terms and the French authorities eventually agreed to an unconditional surrender on 8 September. This effectively completed the British capture of New France.

Background

Following the fall of Quebec in 1759 French forces had retreated westwards. During the winter British forces under James Murray held Quebec but due to the frozen Saint Lawrence River they had to wait until the spring of 1760 until reinforcements and supplies came down. In April Chevalier de Lévis attempted to recapture Québec by launching a surprise assault. After winning the Battle of Sainte-Foy they then laid siege to the city and awaited French reinforcements. The siege lasted from 29 April until 15 May but it was British ships that arrived to relieve the garrison and this compelled Lévis to break off the siege and retreat.
After his defeat, Lévis arrived at Montréal where he conferred with the Governor Marquis de Vaudreuil on future operations. Both exerted themselves for the defence of their colony that would see honour fulfilled despite the odds. Lévis was optimistic when he received news from a French fleet who had sailed from France for Québec on April 15. He soon learned however that this fleet had been intercepted by a Royal Navy blockading squadron off France with a number of ships captured along with the loss of some 500 soldiers. A few ships did get through and proceeded up the Saint Lawrence where they had taken shelter in the Restigouche River by the end of May. They were unable to leave due to the Royal Naval blockade of the Saint Lawrence and so the trapped French ships were then defeated in the Battle of Restigouche in July.
British commanders were eager to bring the campaign to a close as soon as possible. With Murray's forces substantially increased in Québec, the city thus became a staging point for the conquest of the remainder of French Canada. The British then set out a strategy for capturing Montreal, the last major French stronghold, where they would not be able to retreat deeper into the North American continent except for maintained posts in the backcountry. For this British armies would all come under commander-in-chief Jeffery Amherst. He intended to marshal his numerous forces to seek a decisive victory at Montreal.

Prelude

In the winter of 1759–60, a British force had moved from Albany to Lake Ontario and had met up with William Johnson's force that had captured Niagara the previous year. They established a base of operations on Lake Ontario at Oswego and constructed a small fleet which consisted of snows HMS Onondaga, and several row-galleys and gunboats, with a view of transporting an army down the Saint Lawrence River to Montréal. At the same time the British were fighting the Anglo-Cherokee War which had broken out earlier in the year in the Carolinas, and after a desperate appeal by Governor William Lyttelton Amherst was able to spare 1,373 troops but no more.

Three forces would set out: Amherst's would advance Eastward from Lake Ontario along the Saint Lawrence River aiming to cut off the retreat of the French army westward to Détroit where it would have to protract the war longer. His force numbered just over 10,000 men of which just under 4,000 were regulars, consisting of men from the 42nd, 44th, 46th and 55th regiments of foot. The rest were provincials and natives. His was not only the longest but also the most difficult and dangerous, owing to the rapids on the Saint Lawrence. William Haviland's force of two battalions of regular infantry and provincials numbering 3,500 men included the 17th, 22nd, 27th, 40th and the 60th regiments of foot as well as Robert Rogers' famed Rangers. They would advance from upper New York through Lake Champlain via the Richelieu River. This prong would likely come up against the fiercest of the French resistance in terms of defences and fortifications along the way. James Murray would lead the third prong of 4,000 men consisting of the 15th, 28th, 35th, 43rd, 47th, 48th, 58th, 60th and the 78th regiments of foot. In addition there were Moses Hazen's Rangers and a number of natives who would scout ahead. They would advance from Quebec westwards along the Saint Lawrence and would approach the Island of Montreal from the east. All three would converge on Montreal in a pincer movement before winter set in. In total Amherst had at his disposal some 18,000 men who about 60 percent were regulars; the remainder included more than 6,500 provincial soldiers, drawn from every colony north of Pennsylvania, and more than 700 Iroquois warriors.
Amherst ordered Robert Rogers, his Rangers and a few Mohicans on a spoiling attack on French supplies at Forts Chambly, Saint-Jean in the hope that this would weaken French forces and help divert manpower against Murray's advance. The raid which began on 3 June lasted nearly three weeks; departing from Crown Point Rogers learned that the forts were too strong for an assault as they had been reinforced. Nevertheless, they surprised and took the main supply depot at Sainte-Thérèse and had it burned to the ground. On their return journey the British and Mohawks then repelled French ambushes before arriving back to Crown Point to give Amherst the details of the raid. He was delighted with the result and praised Rogers – the British took over 100 soldiers and militia captive, burned or captured valuable supplies and gained vast knowledge on the French defensive works up to Montreal. The raid proved a shock to the inhabitants forcing some militia to desert and many natives to abandon their cause for France. Lévis attempted to raise morale but this had little effect.
Lévis used every available resources for the defence of Montreal; he had a total of eight battalions numbering 3,200 regulars. Lévis could not rely much on his French-allied natives – many were deserting the French cause and some tribes even wanted peace with the British. There was a population of 82,000 and upwards of 20,000 men able to bear arms but most of these were disheartened with the recent defeats and many were ready to surrender their arms to the advancing British. Of the regulars these were composed of the regiments of La Reine, la Sarre, Royal Roussillon, Languedoc, Guyenne, Berry, Béarn and the Compagnies Franches de la Marine. Lévis ordered Captain Pierre Pouchot of the Régiment de Béarn to delay Amherst's approaching army for as long as he could. Pouchot set up his defence of the area at Fort Lévis where he had a garrison of 340 regulars and Canadian militiamen as well as natives. Furthermore, a force under the Chevalier de La Corne was ready to defend the rapids above Montréal, should the British attempt that dangerous passage. The principal French posts barring the lines of Haviland's advance along the Richelieu River were Forts Chambly, Saint-Jean and Île aux Noix. After Roger's attack, these were further reinforced by Louis Antoine de Bougainville which came to some 3,000 regulars, Canadians and natives. In order to prevent Murray from moving upstream from Quebec Lévis ordered Captain Jean-Daniel Dumas to watch the Saint Lawrence with his force of some 1,800 men in addition to several small armed vessels. He had occupied posts at Fort Jacques-Cartier, Deschambault, Trois-Rivières, Sorel on the eastern side of Montréal, Varennes and Pointe-aux-Trembles.

Campaign

Murray's advance

James Murray's prong of 4,000 men set out from Quebec was the first to set out on July 13. 2,000 men would march along the bank whilst the rest were embarked on a fleet of armed vessels and bateau which contained heavy guns and supplies from the Royal Navy in case a protracted siege came about – his advance was the second longest of the three. Facing the British was a series of French defensive positions along the Saint Lawrence; two on the North shore and one on the South shore. Out of all the advances Murray's went through the most populated areas of Canadians, so he therefore had to conduct a counterinsurgency campaign and pacify the population.
On the slow journey upriver to Montreal, Murray's flotilla was harassed by French soldiers but did little to delay his advance. His flotilla engaged French defences at Deschambault following which they seized Grondines in which they dispersed a force of sixty French regulars. Despite this the Canadian population there took Murray's oath, surrendered their arms and exchanges were given. Sainte-Croix followed next and as he advanced further and further Murray was able to pacify the French Canadians and made sure that they swore loyalty to King George II. This was an unqualified success made easier by Murray being able to speak French along with exploiting the failed economy by distributing gold and silver coins. What is more the French military had spread false propaganda - Vaudreuil had warned Canadian inhabitants of cruel unjust treatment by the English but this actually worked against them since it was the French who threatened repercussions if they did not resist the British.
Murray delayed by winds finally reached the French defences at Trois-Rivières by mid August but was able to bypass them much to the annoyance of Dumas who realised that he was by now unable to stop them. Nevertheless, he sent his men to the Northern shore downstream to lay opposite a French force under François-Charles de Bourlamaque in order to fall upon Murray. Hazen's Rangers found the French entrenched along the shore near Sorel on August 21. Murray reluctantly launched an attack under the cover of darkness in two columns of 300 men consisting the Grenadiers and the light companies. The French were dispersed from their defences and the town was put to the torch, but despite Murray's concerns the Canadians threw down their arms and abandoned the French cause. Bourlamaque was furious and wrote to Lévis stating that his troops were deserting him in large numbers.
By August 26 Murray's force was less than from the city and dropped anchor the following day downriver from Montreal. Before he could advance any further eight Sachems of various tribes including the Huron wished to establish peace with Great Britain. Murray however was not empowered to grant any formal treaty or peace to the natives since he was subordinate to Amherst and that would be up to him once the conquest of Montreal and New France was complete. Nevertheless, Murray discussed in length and issued a pass protecting their rights.
The last place of significant defence was at Varennes - Murray sent ahead a detachment of Rangers as well as four companies of grenadiers and light infantry which landed there on 31 August. A French unit consisting of sixty regulars and 320 militia opened fire but the British drove them back. Rocket flares were sent up and this signalled the rest of the British led by Murray to join. After a short firefight the town was secure, a French counterattack was then repelled by the Rangers. Eight of the defenders were killed or wounded with another forty taken prisoner – the British had trifling loses. Varrenes and the surrounding area was then plundered and burned by British troops but despite this it was submitted to Murray. Lévis was kept informed and ordered troops to fall back to Montreal. Over the next few days Murray's Corps had extended along the south bank of the Saint Lawrence and moved up to Sainte-Thérèse, just below Montréal. In that time some four thousand Canadians were disarmed and took the oath of the King. Murray's Corps then encamped and waited for Haviland and Amherst to appear. Murray had made a remarkable achievement; he succeeded in his advance disarming the inhabitants of the riverside parishes and had caused the vast majority of the Canadian militiamen able to bear arms to desert in their thousands on which the French depended for resistance.
