The ill success of these reciprocal attempts at conquest, seems to have discouraged both parties; and the Spanish and English colonies, in the neighbourhood of each other, contented themselves, for the residue of the war, with guarding their own frontiers.
The connexion between the branches of the house of Bourbon was too intimate for the preservation of peace with France, during the prosecution of war against Spain. Both nations expected and prepared for hostilities. War had commenced in fact, though not in form, on the continent of Europe; but as they carried on their military operations as auxiliaries, in support of the contending claims of the elector of Bavaria, and the queen of Hungary, to the imperial throne, they preserved in America a suspicious and jealous suspension of hostility, rather than a real peace.
1744
This state of things was interrupted by a sudden incursion of the French into Nova Scotia.
Hostilities with France.
The governor of Cape Breton having received information that France and Great Britain had become principals in the war, took possession of de Canseau with a small military and naval force, and made the garrison, and inhabitants prisoners of war. This enterprise was followed by an attempt on Annapolis, which was defeated by the timely arrival of a reinforcement from Massachusetts. These offensive operations stimulated the English colonists to additional efforts to expel such dangerous neighbors, and to unite the whole northern continent bordering on the Atlantic, under one common sovereign.
The island of Cape Breton, so denominated from one of its capes, lies between the 45th and 47th degree of north latitude, at the distance of fifteen leagues from Cape Ray, the south western extremity of Newfoundland. Its position rendered the possession of it very material to the commerce of France; and the facility with which the fisheries might be annoyed from its ports, gave it an importance to which it could not otherwise have been entitled. Thirty millions of livres,[135] and the labour of twenty-five years, had been employed on its fortifications. From its strength, and still more from the numerous privateers that issued from its ports, it had been termed the Dunkirk[136] of America. On this place, governor Shirley meditated an attack.
The prisoners taken at Canseau, and others who had been captured at sea and carried to Louisbourg, were sent to Boston. The information they gave, if it did not originally suggest this enterprise, contributed greatly to its adoption. They said that Duvivier had gone to France to solicit assistance for the conquest of Nova Scotia, in the course of the ensuing campaign; and that the store ships from France for Cape Breton, not having arrived on the coast until it was blocked up with ice, had retired to the West Indies.
In several letters addressed to administration, governor Shirley represented the danger to which Nova Scotia was exposed, and pressed for naval assistance. These letters were sent by captain Ryal, an officer of the garrison which had been taken at Canseau, whose knowledge of Louisbourg, of Cape Breton, and of Nova Scotia, enabled him to make such representations to the lords of the admiralty, as were calculated to promote the views of the northern colonies.
The governor was not disappointed. Orders were dispatched to commodore Warren, then in the West Indies, to proceed towards the north, early in the spring; and to employ such a force as might be necessary to protect the northern colonies in their trade and fisheries, as well as to distress the enemy. On these subjects, he was instructed to consult with Shirley, to whom orders of the same date were written, directing him to assist the King's ships with transports, men, and provisions.
