Captain Ord's company, which had suffered so grievously at Fort du Quesne in 1755, having been reinforced from England, was joined in 1757 by two companies under Colonel George Williamson, and a large staff of artificers, the whole being intended to form part of an expedition against the French town of Louisbourg in Cape Breton, now part of the province of Nova Scotia. It was to be Colonel Williamson's good fortune to command the Royal Artillery in America until, in 1760, the English power was fully established on the Continent. When the English captured Annapolis and Placentia in the beginning of the 18th century, the French garrisons were allowed to settle in Louisbourg, which place they very strongly fortified. Its military advantages were not very great, had an attack from the land side been undertaken, for it was surrounded by high ground; but it had an admirable harbour, and it was very difficult to land troops against the place from the sea side of the town. The harbour lies open to the south- east, and is nearly six miles long, with an average depth of seven fathoms, and an excellent anchorage. There was abundance of fuel in the neighbourhood, both wood and coal; in fact, the whole island was full of both; and there were casemates in the town which could greatly shelter the women and children during a bombardment. Generally some French men- of-war were in the harbour; and in 1757, when the siege was first proposed to be undertaken, so strong was the French fleet at Louisbourg, that the English commanders postponed their operations until the following year. Had our statesmen been better acquainted with geography, it is probable that at the Peace of Utrecht, when Nova Scotia and Newfoundland were authoritatively pronounced to be English territory, Cape Breton would have also been included; but being an island, and separate from Nova Scotia although immediately adjoining it, the French did not consider that it fell within the treaty, and clung to it, as they always had to the maritime provinces of Canada. The siege of 1758 was not the first to which Louisbourg had been subjected. In 1745 an expedition had been fitted out from Massachusetts— the land forces being American Militia under Colonel Pepperell, and the naval contingent being composed of English men-of-war under Commodore Warren. The amicable relations between the naval and military commanders tended greatly to bring about the ultimate success. The American Militia were badly trained, and far from well disciplined, but they were brave, headstrong, and animated by strong hatred of their old enemies the French. Powerful as Louisbourg was (it was called the Dunkirk of America) the Americans did not hesitate to attack it, and they were justified by the result. On the 30th April, 1745, the siege commenced; on the 15th June, M. Du Chambon, the Governor of Louisbourg, signed the capitulation.
