A few days before this attack on Beauport was made, the French again paid the fleet the undesired attention of a large fire raft composed of several small vessels chained together and laden with all sorts of combustibles--shells, guns loaded to the muzzle, tar barrels, etc., and again this was grappled by the boats and towed away to a place of safety; and then Wolfe, sending in a flag of truce the next morning, said that if the performance were repeated he should cause the instrument of destruction to be towed alongside two ships in which he had Canadian prisoners, and there let it do its worst. This somewhat cold-blooded threat was sufficient, and the experiment was not repeated. A NARROW ESCAPE. During the time the fleet was occupying the Basin, the Masters of the ships were constantly out making observations and sounding, partly for the necessities of the fleet and partly to throw dust in the eyes of the French; and on one occasion Cook had a narrow escape from capture, his men had to row for it to get away from the enemy, and reaching the Isle of Orleans landed just in time, for as Cook, the last man, sprang ashore from the bows an Indian boarded over the stern. The hospital picket turned out, and the French retreated. His friend, Mr. Bissett, was not so fortunate, being taken prisoner on 7th July whilst sounding in the north channel; but he was either exchanged or escaped, for he was only absent from his ship for a few days. Wolfe, who was almost always ailing, had an attack of fever, and the worry of the repulse at Beauport rendered him incapable of duty for some days; he therefore laid before his Brigadiers plans of future movements, asking their opinions and advice. These plans were not approved, but it was suggested that an attempt should be made to land on the western side of the town and there bring the enemy to action, and Wolfe writes: "I have acquiesced in their Proposal, and we are preparing to put it into execution." The up-river detachment had been strengthened by the addition of a few more vessels, and Murray with 1200 men had joined in an unsuccessful attempt to get at the French supply fleet which had retreated to a place of safety. He had outwitted De Bougainville, who was detached to watch him, and succeeded in destroying a magazine containing clothing, powder, and other stores, and intercepted letters which told of the surrender of Niagara and the retirement of Bourlemaque upon the Ile aux Noix, to which place Amherst was preparing to follow.
