In 1745, the year when the power of France in Europe was exalted by the splendid victory of Fontenoy, a dangerous blow was struck at her sovereignty in America by the capture of Louisburg, and with it the whole island of Cape Breton,[424] by the New Englanders under Mr. Pepperel,[425] aided by Admiral Warren's squadron. This disaster was no sooner known in Paris[430] than an extensive armament was equipped under the command of the Duc d'Anville, an officer of known valor and ability. The wounded pride of the French hurried on rapidly the preparations for this expedition, which they confidently hoped would redeem the tarnished honor of their arms in the Western world. Early in May the fleet was already completely appointed; but the elements did not second these energetic preparations, and contrary winds detained the armament till the 22d of June. Then it at last put to sea, in the formidable strength of eleven ships of the line, thirty smaller vessels of war, and transports containing 3000 regular soldiers. Nova Scotia, the Acadia[431] of other days, was their destination. There it was expected that the old French settlers, who had unwillingly submitted to English conquest, would readily range themselves once more under the fleur-de-lys: Canada had already sent her contingent of 1700 men under M. de Ramsay to aid the enterprise, and M. de Conflans, with four ships of the line from the West Indies, was directed to join the squadron.

This formidable fleet was but a short time at sea when the ships separated and fell into hopeless confusion. On the 12th of September, indeed, the Duc d'Anville reached the Western continent in the Northumberland, accompanied by a few other vessels, but there no laurels awaited the gallant admiral: he was suddenly seized with apoplexy, and in four days his body was committed to the deep. The vice admiral immediately proposed returning to France, on account of the absence of the greater part of his force; but other officers strongly opposed this desponding counsel, and urged a bold attack upon Nova Scotia[432] rather than an inglorious retreat. The more vigorous course was adopted by a council of war, which threw the vice admiral into such a state of frantic excitement that he ran himself through the body, fancying he had fallen into the hands of the enemy. De la Jonquière succeeded to the command, and, although more than three-score years of age, acted with unimpaired energy. But the elements were again hostile to France; the fleet was dispersed by a violent storm off Cape Sable, and the shattered remnant of the expedition returned ingloriously to their country, without having accomplished any of the objects for which they had been sent forth.

The government at Paris was, however, by no means cast down by these untoward occurrences, and the armament was speedily equipped to renew their efforts against the English colonies. The expedition was prepared at Brest, under the command of M. de la Jonquière, and, at the same time, a squadron under M. de St. George was armed with a view to threaten the coasts of British India.

The English ministry, early informed of all the movements of their opponents, resolved to intercept both these squadrons, which they had been apprised would sail from port at the same time. Admiral Anson and Rear-admiral Warren were ordered upon this enterprise with a formidable fleet, and, taking their departure from Plymouth, steered for Cape Finisterre, on the Gallican coast. On the third of May, 1746, they fell in with the French squadrons of six large men-of-war, as many frigates, four armed East Indiamen, and a valuable convoy of thirty ships. The enemy's heavier vessels immediately formed in order of battle, while the merchantmen made all sail away, under the protection of the frigates. The British were also ready for action, and a severe combat ensued. Before night all the French line of battle ships were captured after a spirited defense, but two thirds of the convoy escaped through the darkness of the night. A considerable quantity of bullion fell into the hands of the victors, and their grateful sovereign rewarded the courage and good fortune of the admirals by raising Anson to the peerage, and decorating Warren with the ribbon of the Bath.

Admiral de la Jonquière, the newly-appointed governor of Canada, was among the numerous captives who graced the triumph of the British fleet. When the news of this event reached Paris, the king appointed to the vacant dignity the Comte de la Galissonière,[433] an officer of distinguished merit and ability. The wisdom of this selection was speedily displayed; the new governor no sooner entered upon the duties of office than his active zeal found employment in endeavoring to develop the magnificent resources of his province. He made himself thoroughly acquainted with the face of the country, the climate, population, agriculture, and commerce, and then presented an able statement to the French court of the great importance of the colony, and a system which, had it been adopted in time, might have secured it against English aggression.

The Comte de la Galissonière proposed that M. du Quesne, a skillful engineer, should be appointed to establish a line of fortifications through the interior of the country, and, at the same time, urged the government of France to send out 10,000 peasants to form settlements on the banks of the great lakes and southern rivers. By these means he affirmed that the English colonies would be restricted within the narrow tract lying eastward from the Allegany Mountains, and in time laid open to invasion and ruin. His advice was, however, disregarded, and the splendid province of Canada soon passed forever from under the sway of France.[434]

Under the impression that the expected peace between the mother countries would render it important to define the boundaries of their colonial possessions, the active governor of Canada dispatched M. de Celeron de Bienville, with 300 men, to traverse the vast wilderness lying from Detroit southeast to the Apalachian Mountains. Assuming this range as the limit of the British colonies, he directed that leaden plates, engraved with the arms of France, should be buried at particular places in the western country, to mark the territories of France, and that the chief of the expedition should endeavor to secure a promise from the Indians to exclude for the future all English traders. At the same time, he gave notice to the governor of Pennsylvania that he was commanded by the King of France to seize all British merchants found in those countries, and to confiscate their goods. De Celeron fulfilled his difficult commission to the best of his powers, but the forms of possession which he executed excited the jealous apprehension of the Indians, who concluded that he designed to subject or even enslave them.

When M. de la Galissonière failed in his endeavor to obtain the aid of an extensive immigration from France, he turned his thoughts toward the Acadian settlers[435] (whom the treaty of Utrecht had transferred to the British crown), with the object of forming a new colony. The readiest expedient to influence this simple and pious people was, obviously, by gaining over their clergy; the Abbé le Loutre was selected as the fittest embassador to induce them to withdraw from allegiance to the English government. This politic and unscrupulous priest appealed to their interests, nationality, and religion as inducements to abandon the conquered country, and to establish themselves under the French crown in a new settlement which he proposed to form on the Canadian side of Acadia. Le Loutre's persuasions influenced many of these primitive people to proceed to the French posts, where every protection and attention was bestowed upon them.

Animated by the success of this measure, and sanguine that large numbers of the Acadians would follow the first seceders, De la Galissonière induced the home government to appoint a considerable sum yearly to carrying out his views; but, in the midst of his patriotic exertions, he was obliged to hand over the reins of government to M. de la Jonquière, who had now arrived to claim the post so ably held by another during his captivity with the English. Galissonière, however, before he sailed for France, magnanimously furnished his successor with the best information on colonial matters, and pointed out the most promising plans for the improvement of the province.[436] De la Jonquière unwisely rejected such as related to the Acadian settlements; but the King of France disapproved of his inaction, and reprimanded him for not having continued the course of his predecessor. Instructions were given him to take immediate possession of the neighboring country, to build new forts for its retention, and to occupy it with troops; he was also desired to aid Le Loutre in all his proceedings, and to forward his designs. In obedience to these orders, M. de Boishebert was dispatched with a body of troops and some peasants, to take post near the mouth of the River St. John, which was looked upon as an important post for the defense of the new settlement.

These measures inevitably aroused the jealousy of the English governor of Nova Scotia, who made repeated remonstrances on the subject, but with no other effect than that of causing De la Jonquière to warn his officers to avoid all possible grounds of dispute, as he expected the limits of the rival powers would be speedily arranged.
