General Amherst established the English camp just beyond the range of the cannon on the ramparts, and the fleet set to work to land guns and stores at Flat Point Cove. For some days this work went on; but so violent was the surf, that more than a hundred boats were stove in in accomplishing it, and none of the siege guns could be landed till the 18th. While the sailors were so engaged, the troops were busy making roads and throwing up redoubts to protect their position.
Wolfe, with 1200 men, made his way right round the harbour, and took possession of the battery at Lighthouse Point which the French had abandoned; planted guns and mortars there, and opened fire on the battery on the islet which guarded the entrance to the harbour; while other batteries were raised, at different points along the shore, and opened fire upon the French ships. These replied, and the artillery duel went on night and day, until, on the 25th, the battery on the islet was silenced. Leaving a portion of his force in the batteries he had erected, Wolfe returned to the main army in front of the town.
In the meantime, Amherst had not been idle. Day and night a thousand men had been employed, making a covered road across a swamp to a hillock less than half a mile from the ramparts. The labour was immense, and the troops worked knee deep in mud and water.
When Wolfe had silenced the battery on the islet, the way was open for the English fleet to enter and engage the ships and town from the harbour, but the French took advantage of a dark and foggy night, and sank six ships across the entrance.
On the 25th, the troops had made the road to the hillock, and began to fortify themselves there, under a heavy fire from the French; while on the left, towards the sea, about a third of a mile from the Princess's Bastion, Wolfe, with a strong detachment, began to throw up a redoubt.
On the night of the 9th of July, 600 French troops sallied out and attacked this work. The English, though fighting desperately, were for a time driven back; but, being reinforced, they drove the French back into the town.
Each day the English lines drew closer to the town. The French frigate Echo, under cover of a fog, had been sent to Quebec for aid, but she was chased and captured. The frigate Arethuse, on the night of the 14th of July, was towed through the obstructions at the mouth of the harbour, and, passing through the English ships in a fog, succeeded in getting away. Only five vessels of the French fleet now remained in the harbour, and these were but feebly manned, as 2000 of the officers and seamen had landed, and were encamped in the town.
On the afternoon of the 16th a party of English, led by Wolfe, suddenly dashed forward, and, driving back a company of French, seized some rising ground within three hundred yards of the ramparts, and began to intrench themselves there. All night, the French kept up a furious fire at the spot, but, by morning, the English had completed their intrenchment, and from this point pushed on, until they had reached the foot of the glacis.
On the 21st, the French man of war Celebre was set on fire by the explosion of a shell. The wind blew the flames into the rigging of two of her consorts, and these also caught fire, and the three ships burned to the water's edge. Several fires were occasioned in the town, and the English guns, of which a great number were now in position, kept up a storm of fire night and day.
On the night of the 23rd, six hundred English sailors silently rowed into the harbour, cut the cables of the two remaining French men of war, and tried to tow them out. One, however, was aground, for the tide was low. The sailors therefore set her on fire, and then towed her consort out of the harbour, amidst a storm of shot and shell from the French batteries.
