In February, 1808, he was selected to command a brigade destined to reinforce Nova Scotia, where he succeeded Sir John Wentworth as Governor, and in December, 1808, he left Halifax, in order to assist in the reduction of Martinique. The expedition sailed from Barbadoes on the 28th of January, 1809, and on the 30th, the troops were landed on the island of Martinique. Sir George Prevost was second in command under General Sir George Beckwith, and to him the management of all the active operations was confided. The result of this expedition was, that the French troops were driven into Fort Bourbon, where they held out until the 24th of February, when the surrender of that fort completed the conquest of the island.[18]

Upon the conclusion of this short but brilliant campaign, Sir George Prevost passed a few days at Dominica, where he was received with many demonstrations of joy. Addresses were upon this occasion presented to him by the House of Assembly of Dominica, and by the merchants and inhabitants of St. Christophers.[19]

In the month of April the army returned to Halifax, and from this period until his appointment to the chief civil and military command in British North America, in 1811, upon the resignation of Sir James Craig, Sir George Prevost remained in Nova Scotia, esteemed and beloved by all ranks of the inhabitants. On his departure for his new government, he received the most gratifying addresses from the inhabitants of Halifax,[20] and from the clergy of Nova Scotia, &c. &c.[21]

Upon the arrival of Sir George Prevost at Quebec in 1811, he found much dissatisfaction and discontent existing in the Lower Province. The inhabitants were divided into two parties, termed the English and the Canadian, and the feelings of hostility with which they viewed each other, had unfortunately not been allayed by the policy which the late Governor in Chief, Sir James Craig, had thought it necessary to adopt during his administration. To such a degree had this party spirit been carried, and so doubtful had he been of the disposition of the Canadians, that it had been thought inexpedient to call out the militia, lest they should make an improper use of the arms to be intrusted to them. Under these circumstances, it was evidently the duty of Sir George Prevost to conciliate, by every means in his power, the confidence and affection of the Canadians, more particularly as in case of hostilities with America, it would have been impossible to preserve Lower Canada without the cordial support of its inhabitants. Sir George Prevost therefore did not hesitate to adopt a system which the true interest of the Province seemed so imperiously to require. He anxiously endeavoured to unite the two adverse parties, and to soothe the irritation which not only threatened the tranquillity of his government, but even the safety of the colony itself. In the distribution of the patronage which he enjoyed, he resolved to be guided solely by a consideration of the public good, and when offices became vacant, he bestowed them, with a due regard to the merits of the individuals, indifferently upon the English and the Canadians.

The beneficial effects of these measures became every day more apparent. The Governor in Chief speedily acquired the confidence of all ranks of people, who submitted with cheerfulness to the privations and sacrifices which they were soon afterwards called upon to endure. In numerous instances he received from the inhabitants, both collectively and individually, the strongest proofs of their zeal; and he had the satisfaction of seeing them united in their attachment to his government, at a time when the preservation of the colony depended upon such feelings.

Having thus given a brief sketch of the situation in which the Governor in Chief found the Province of Lower Canada upon his arrival, and of the views and objects which he entertained respecting it, we shall proceed to point out the conduct which he pursued, when, from the aspect of affairs, it became evident that hostilities with America could not be long delayed. No sooner had Sir George Prevost assumed the chief command of the Canadas, than he became sensible of the necessity of placing those provinces in the most efficient state of defence; and he therefore applied himself with the utmost vigour and vigilance to call forth all their resources. It is difficult to believe that the unwearied exertions of Sir George Prevost, with a view to this important object, should have been altogether unknown to the writer in the Quarterly Review. But supposing him to have been ignorant of them, yet without access to the private and confidential correspondence which took place between Sir George Prevost and his Majesty's Government, or to the communications which passed between him and the officers under his command, it was impossible that the Reviewer could form a correct opinion upon the subject. And yet he has not hesitated boldly to assert, that, "in the winters of 1811 and 1812, although the designs upon the Canadas were openly avowed in the American Congress, except the embodying of the militia of the Lower Province, Sir George Prevost made not the slightest preparation for defence."[22] The following statement will show the degree of credit to which this assertion of the Reviewer is entitled.

In the month of September, 1811, Sir George Prevost arrived in Canada, and in the same month, proceeding from Quebec to the district of Montreal, he inspected the different forts and military positions in that neighbourhood, and on the American frontier. Soon after his return to Quebec in the November following, he communicated confidentially with the Adjutant-General of the forces in England, upon the apprehended hostilities with America. In December he proposed to Lord Liverpool, then Secretary of State for the Colonies, the raising a corps of Fencibles, from the Glengarry settlement in Upper Canada; and in his correspondence with Admiral Sawyer, who commanded on the Halifax station, he requested that a ship of war might be sent, on the opening of the navigation, to the St. Lawrence. In the month of February, 1812, another communication was made to the Secretary of State's Office, in which Sir George Prevost expressed a hope, that the proceedings in Washington would justify him, in making preparations to repel the threatened attack. Those preparations had been commenced as early as November, 1811, by forwarding arms and ammunition to the Upper Province. During the winter of 1811 and 1812, and the spring of the latter year, frequent communications passed between the Commander of the forces and Major-General Brock, who commanded in Upper Canada, respecting the preparations which would be necessary in the event of a war. It was proposed to reinforce Amherstburgh, and Fort George; and supplies of provisions, cavalry-arms, accoutrements and money, were directed to be conveyed to Upper Canada. Accoutrements and clothing for the militia in the Canadas, were requested from the British Government. Another schooner was directed to be built, to increase our marine on Lake Erie. Captain Gray, Deputy Assistant-Quarter-Master-General, was despatched to the Upper Province, in order to assist in forwarding these defensive preparations; and Captain Dixon, of the Royal Engineers, was directed to proceed to Amherstburgh, to inspect the works of that fort, which the Commander of the forces had ordered to be put in a tenable state. The propriety of strengthening and fortifying York was submitted to Government; and the commanding engineer was directed to make the repairs, which his report on the different forts and posts in Upper Canada, had stated to be necessary. In addition to these measures, a reinforcement from the 41st regiment, and five companies of the Newfoundland Fencibles, left Quebec in the month of May for the Upper Province.

On the 31st March, Sir George Prevost addressed a private and confidential letter to Major-General Brock, in which his sentiments respecting the approaching war, and the policy to be adopted in meeting it, were clearly detailed. One passage in this letter merits a more particular notice, since it is highly important, not only as repelling the accusation of the Reviewer respecting the want of preparation for the war, but also as containing an answer to another charge, which will afterwards be noticed. The paragraph in the letter is as follows: "You are nevertheless to persevere in your preparations for defence, and in such arrangements as may, upon a change in the state of affairs, enable you to employ any disposeable part of your force offensively against the common enemy."

Independently of all these various communications with the officer commanding in Upper Canada, respecting the measures to be pursued in the event of war, and of the supplies of men, arms, money, stores, and provisions, which, with a view to that event, had been afforded to Upper Canada; much correspondence had previously taken place, and many difficulties had been removed with regard to the supply and transport of the Indian presents to the Upper Province, upon the due furnishing of which very materially depended the support which we might expect to receive from the Indians, in case of a rupture with America.

From this statement, drawn from the original correspondence, and from official documents, it is evident, that even in contemplation of hostilities, an event by no means certain, and which the British Government were so far from thinking probable, that they discouraged any measure of extraordinary expense to meet it, the Commander of the forces did, as far as rested with him, during the winter of 1811 and 1812, and for months prior to the declaration of war, make every preparation for defence, consistent with the means which he possessed. All the requisitions of Major-General Brock which the Commander of the forces had the power to grant, were promptly complied with; nor was the slightest intimation ever given by that invaluable officer, that any measure, either suggested by himself or which ought to have occurred to the Commander of the forces, for the preservation of the Upper Province, in the event of its being attacked, had been overlooked or neglected. The same vigilant foresight will be found to mark the conduct of Sir George Prevost in the Lower Province. One of the first measures of his government, in contemplation of war, was an application to the legislature of Lower Canada, in February, 1812, for an act to new model the militia laws, and which might enable him to call forth a proportion of the population into active service. Averse as the Canadians had hitherto been to grant any power of this description to former Governors, and repugnant as many of the clauses which it was intended to introduce into the bill, were to the habits and feelings of the people, such was the deserved popularity acquired by Sir George Prevost, from the conciliatory policy, which, as before stated, he had adopted towards the Canadians, immediately upon his arrival amongst them, that he obtained from the Legislature nearly all that he had required. Before the end of May, 1812, a sum exceeding 60,000l. was placed at his disposal for the militia service; and he was authorized to embody 2,000 Bachelors, between the age of eighteen and twenty-five years, for three months in the year; and in case of invasion, or imminent danger of it, to retain them for a year. In case of war, he was empowered to embody if necessary, the whole militia of the Province. Under that law, a force of 2,000 men, from the finest and most efficient class of the militia, was embodied on the 13th May, so to remain for three months, unless the then state of affairs should render it expedient to retain them longer. A corps of Canadian voltigeurs, under the command of Major De Salaberry, of the 60th regiment, consisting of between 300 and 400 men, had likewise, been raised and disciplined; and 400 recruits for the Glengarry Fencibles, had, before the 1st June, been assembled at Three Rivers, in Lower Canada. The advantages arising from thus embodying the militia prior to the war, were incalculable, and it may be confidently asserted, materially contributed to the preservation of the Canadas.
