The English occupation of the Grand Battery may be called the decisive event of the siege. There seems no doubt that the French could have averted the disaster long enough to make it of little help to the invaders. The water-front of the battery was impregnable. The rear defences consisted of a loopholed wall of masonry, with a ditch ten feet deep and twelve feet wide, and also a covered way and glacis, which General Wolcott describes as unfinished. In this he mistook. They were not unfinished, but had been partly demolished, with a view to reconstruction. The rear wall was flanked by two towers, which, says Duchambon, were demolished; but General Wolcott declares that swivels were still mounted on them,[106] and he adds that “two hundred men might hold the battery against five thousand without cannon.” The English landed their cannon near Flat Point; and before they could be turned against the Grand Battery, they must be dragged four miles over hills and rocks, through spongy marshes and jungles of matted 103 evergreens. This would have required a week or more. The alternative was an escalade, in which the undisciplined assailants would no doubt have met a bloody rebuff. Thus this Grand Battery, which, says Wolcott, “is in fact a fort,” might at least have been held long enough to save the munitions and stores, and effectually disable the cannon, which supplied the English with the only artillery they had, competent to the work before them. The hasty abandonment of this important post was not Duchambon’s only blunder, but it was the worst of them all. On the night after their landing, the New England men slept in the woods, wet or dry, with or without blankets, as the case might be, and in the morning set themselves to encamping with as much order as they were capable of. A brook ran down from the hills and entered the sea two miles or more from the town. The ground on each side, though rough, was high and dry, and here most of the regiments made their quarters,--Willard’s, Moulton’s, and Moore’s on the east side, and Burr’s and Pepperrell’s on the west. Those on the east, in some cases, saw fit to extend themselves towards Louisbourg as far as the edge of the intervening marsh, but were soon forced back to a safer position by the cannon-balls of the fortress, which came bowling amongst them. This marsh was that green, flat sponge of mud and moss that stretched from this point to the glacis of Louisbourg.
