The joy excited in the British colonies by the success of the expedition against Louisbourg was unbounded. Even those who had refused to participate in its hazards and expense, were sensible of its advantages, and of the lustre it shed on the American arms. Although some disposition was manifested in England, to ascribe the whole merit of the conquest to the navy, colonel Pepperel received, with the title of baronet, the more substantial reward of a regiment in the British service, to be raised in America; and the same mark of royal favour was bestowed on governor Shirley. Reimbursements too were made by parliament for the expenses of the expedition. It was the only decisive advantage obtained by the English during the war.
The capture of Louisbourg, most probably, preserved Nova Scotia. Duvivier, who had embarked for France to solicit an armament for the conquest of that province, sailed, in July, 1745, with seven ships of war, and a body of land forces. He was ordered to stop at Louisbourg, and thence to proceed in the execution of his plan. Hearing, at sea, of the fall of that place, and that a British squadron was stationed at it, he relinquished the expedition against Nova Scotia, and returned to Europe.
The British empire on the American continent consisted, originally, of two feeble settlements unconnected with, and almost unknown to each other. For a long time the southern colonies, separated from those of New England by an immense wilderness, and by the possessions of other European powers, had no intercourse with them, except what was produced by the small trading vessels of the north, which occasionally entered the rivers of the south. Neither participated in the wars or pursuits of the other; nor were they, in any respect, actuated by common views, or united by common interest. The conquest of the country between Connecticut and Maryland, laid a foundation, which the settlement of the middle colonies completed, for connecting these disjoined members, and forming one consolidated whole, capable of moving, and acting in concert. This gradual change, unobserved in its commencement, had now become too perceptible to be longer overlooked; and, henceforward, the efforts of the colonies, were in a great measure combined, and directed to a common object.
