Great preparations were made throughout the fleet and army for the decisive movement, but the plans were still kept secret; a wise caution was observed in this respect, for the treachery of a single deserter might have imperiled the success of the expedition had its exact object been known. On the morning of the 12th, a soldier of the Royal Americans did desert: happily, he was unable to warn the enemy of their danger. Almost at the same time, one of the French regulars deserted to Wolfe, and brought a clear account of the state of affairs in Montcalm's camp. "The main force is still below the town," said he; "our general will not believe that you meditate an attack any where but on the Montmorency side. The Canadians are dissatisfied, alarmed by the fall of Niagara, and in great distress for provisions. M. de Levi, with a large detachment, has left us for Montreal, to meet Amherst; and M. de Bougainville, with 1500 men, watches the motions of your fleet in the Upper River." From on board the Sutherland man-of-war, Wolfe issued his last orders to the army on the evening of the 12th of September: "The enemy's force is now divided, great scarcity of provisions is now in their camp, and universal discontent among the Canadians, which gives us reason to think that General Amherst is advancing into the colony: _a vigorous blow struck by the army at this juncture may determine the fate of Canada_ ... the troops will land where the French seem least to expect it. The first body that gets on shore is to march directly to the enemy ... the battalions must form on the upper ground with expedition, and be ready to charge whatever presents itself.... The officers and men will remember what is expected from them, and what a determined body of soldiers, inured to war, is capable of doing, against five weak French battalions, mingled with a disorderly peasantry." The heavier ships of the line moved this evening toward the Beauport shore, anchoring as near the enemy's lines as the depth of the water would permit. While daylight yet remained, all the boats of that portion of the fleet were lowered, filled with marines and seamen, and ranged in order, threatening a descent upon the shore. At the same time, the remaining ships suddenly hoisted sail; and, with a favoring breeze, swept proudly past the batteries of Quebec, and joined Holmes's squadron at Cape Rouge, eight miles above the city. Monckton and Murray, who, with their brigades, still occupied Point Levi and the village of St. Michael's, now pushed rapidly up the left bank of the St. Lawrence till they arrived opposite the fleet, and there embarked without being observed by the enemy. At nine o'clock at night the first division of the army, 1600 strong, silently removed into flat-bottomed boats; the soldiers were in high spirits; Wolfe led in person. About an hour before daylight the flotilla fell down with the ebb tide. "Weather favorable; a star-light night."
