Pursuant to the policy thus outlined, which had no less in view than the rehabilitation of Canada, the recovery of Nova Scotia, the mastery of the St. Lawrence, and the eventual restoration of French prestige in America, France had in thirty years created at Louisburg a fortress so strong that it was commonly spoken of as the Dunkirk of America. To do this she had lavished millions.[1] Beyond question it was the most formidable place of arms on the American continent, far exceeding in this respect the elaborate but antiquated strongholds of Havana, Panama, and Carthagena, all of which had been built and fortified upon the old methods of attack and defence as laid down by the engineers of a previous century: while Louisburg had the important advantage of being planned with all the skill that the best military science of the day and the most prodigal expenditure could command. When their work was done, the French engineers boastingly said that Louisburg could be defended by a garrison of women. Armament of Louisburg. The fortress, and its supporting batteries, mounted nearly one hundred and fifty pieces of artillery on its walls, some of which were of the heaviest metal then in use. It was deemed, and indeed proved itself, during the progress of two sieges, absolutely impregnable to an attack by a naval force alone. From this stronghold Louis had only to stretch out a hand to seize upon Nova Scotia, or drive the New England fishermen from the adjacent seas. In New England all these proceedings were watched with the keenest interest, for there, at least, if nowhere else, their true intent was so quickly foreseen, their consequences so fully realized, that the people were more and more confounded by the imbecility which had virtually put their whole fishery under French control. As the situation in Europe was reflected on this side of the Atlantic, it is instructive to look there for the storm which, to the terror and dismay of Americans, was now darkly overspreading the continent.
