Within seven weeks after Shirley issued his proclamation preparations for the expedition were complete. The force, all told, numbered about four thousand men. Transports were easily obtained in the harbor of Boston or in the towns adjoining. There was a lack of cannon of large calibre, but it was known that the French possessed cannon of large calibre, so cannon balls and supplies to fit such guns were carried along, it being foreseen that the army would capture sufficient of the French cannon to supply its needs. Of other supplies there was a sufficiency and, to overbalance the lack of any military training whatever in the officers, Governor Shirley had written a long list of instructions for the siege. These instructions, after going into such minute directions as how to make fast the windows of the Governor’s apartment at Louisburg, and outlining a complex series of military manœuvres to be undertaken after dark by men who had no idea of the country they would be in, ended with the words, “Notwithstanding the instructions you have received from me I must leave you to act, upon unforeseen emergencies, according to your best discretion.” On Friday, April 5, 1745, the first of the transports arrived at Canseau, the rendezvous, about sixty miles from Louisburg, and this little post which had now a small French garrison changed hands again. Captain Ammi Cutter was put in command with sixty-eight men. On Sunday there was a great open-air concourse at which Parson Moody preached on the text “Thy people shall be willing in the day of Thy power.” Parson Moody’s sermon was disturbed by the drilling of an awkward squad whose men were learning how to handle a musket. For three weeks the expedition lay at Canseau waiting for the ice to clear from the northern waters, and then, on the morning of the 29th, it set out expecting to make Louisburg by nine o’clock that evening and to take the French by surprise as Shirley had directed. The French, of course, had been aware all the time of the location of the enemy and had even had intelligence from Boston when the affair was first bruited about. A lull in the wind caused a change in the plan of taking the French by surprise and it was not until the keen light of the following morning that the New Englanders saw Louisburg, no very great sight at that, as the buildings of the town were almost completely hid behind the massive walls which encircled them.
