On the 18th of July a fresh move was made by the English.  The French had believed it impossible for any hostile ships to pass the batteries of Quebec; but, covered by a furious cannonade from Point Levi, the man of war Sutherland, with a frigate and several small vessels, aided by a favouring wind, ran up the river at night and passed above the town.  Montcalm at once despatched six hundred men, under Dumas, to defend the accessible points in the line of precipices above Quebec, and on the following day, when it became known that the English had dragged a fleet of boats over Point Levi, and had launched them above the town, a reinforcement of several hundreds more was sent to Dumas.

On the night of the 20th Colonel Carleton, with six hundred men, rowed eighteen miles up the river, and landed at Pointe aux Trembles on the north shore.  Here, many of the fugitives from Quebec had taken refuge, and a hundred women, children and old men were taken prisoners by Carleton, and brought down the next day with the retiring force.  Wolfe entertained the prisoners kindly, and sent them, on the following day, with a flag of truce into Quebec.

On the night of the 28th, the French made another attempt to burn the English fleet, sending down a large number of schooners, shallops, and rafts, chained together, and filled, as before, with combustibles.

This time, the fire was not applied too soon, and the English fleet was for some time in great danger, but was again saved by the sailors, who, in spite of the storm of missiles, vomited out by cannon, swivels, grenades, shell, and gun and pistol barrels loaded up to the muzzle, grappled with the burning mass, and towed it on shore.

It was now the end of July, and Wolfe was no nearer taking Quebec than upon the day when he first landed there.  In vain he had tempted Montcalm to attack him.  The French general, confident in the strength of his position, refused to leave it.

Wolfe therefore determined to attack the camp in front.  The plan was a desperate one, for, after leaving troops enough to hold his two camps, he had less than five thousand men to attack a position of commanding strength, where Montcalm could, at an hour’s notice, collect twice as many to oppose him.

At a spot about a mile above the gorge of the Montmorenci a flat strip of ground, some two hundred yards wide, lay between the river and the foot of the precipices, and, at low tide, the river left a flat of mud, nearly half a mile wide, beyond the dry ground.

Along the edge of the high-water mark, the French had built several redoubts.  From the river, Wolfe could not see that these redoubts were commanded by the musketry of the intrenchments along the edge of the heights above, which also swept with their fire the whole face of the declivity, which was covered with grass, and was extremely steep.  Wolfe hoped that, if he attacked one of the redoubts, the French would come down to defend it, and that a battle might be so brought on; or that, if they did not do so, he might find a spot where the heights could be stormed with some chance of success.  At low tide, it was possible to ford the mouth of the Montmorenci, and Wolfe intended that the troops from his camp, on the heights above that river, should cross here, and advance along the strand to cooperate with Monckton’s brigade, who were to cross from Point Levi.
