These vessels now called the _Shannon_ and the _Blake_, as forget-me-nots of an action recently fought, but not yet noticed, in Chesapeake Bay, were speedily turned to excellent use. It was conceived expedient to destroy the barracks, hospitals and stores at Plattsburgh, Burlington, Champlain, and Swanton, if possible, and an expedition was accordingly fitted out at Isle-aux-Noix. The two captured sloops of war were repaired and made ready for the lake. Captain Pring, from Lake Ontario, was promoted to the rank of commander and sent to take command, but the sloop of war _Wasp_, having shortly afterwards arrived at Quebec, Captain Everard, with his whole crew, were sent to Isle-aux-Noix, and as senior officer assumed the command of the two vessels and the three gun-boats. The squadron sailed on the 29th of July, with about nine hundred men on board, consisting of detachments of the 13th, 100th, and 103rd regiments of the line, under Lieutenants Colonel Taylor and Smelt, some royal artillery under Captain Gordon, and a few militia, as batteaux men, under Colonel Murray. The expedition was altogether successful. At Plattsburgh, the American General, Moore, made no opposition to the landing of the British, but retired with fifteen hundred soldiers, Murray, meanwhile, destroying the arsenal, public buildings, commissariat stores, and the new barracks, capable of accommodating five thousand men. Neither did the squadron lie idly by. Captains Everard and Pring, in the _Growler_ and _Eagle_, proceeded to Burlington, and threw the place into the utmost consternation. Gen'l. Hampton, who was encamped there with four thousand men, was unable to prevent the capture and destruction of four vessels. And the two ships did not linger there either unnecessarily. They went back to Plattsburgh, re-embarked the troops, and proceeded to Swanton, Colonel Murray sending a detachment to Champlain to destroy the barracks and blockhouse. At Swanton the object of the expedition was accomplished, and the expedition returned without casualty.
Public opinion had its effect upon the Admiralty, notwithstanding the stubborn resistance of the old Lords, who still privately persisted in the notion that an old tub, manned by monkeys, if commanded by an officer in the royal navy, was a match for the best American frigate that ever floated. There had for some time back been considerable activity in the English dockyards. Several vessels were commenced on the model of the American frigates, and the commanders of frigates and sloops of war, on the American coast, were cautioned not to expose themselves to certain destruction by attacking large and heavily armed vessels, only nominally of the same rank or class as themselves. There was to be a real, not an apparent equality. There was to be an equality in tonnage, an equality in the number of guns, an equality in the weight of metal, an equality in the thickness of a ship's sides, and above all an equality in men, so far as such equality could be ascertained. Equality in sailing power was of great importance, but where it was wanting, the superior sailor, if superior in metal and men had an advantage which nothing but a calm or a lucky hit aloft could destroy. The crews of every ship on the North American Station were to be exercised in gunnery. Wisdom had been luckily forced upon the Admiralty. And the result was good. Sir John Borlase, the naval commander, in North America, blockaded every harbour in the United States. American commerce was ruined. The carrying trade of the Atlantic was no longer in American hands. The public revenue sank from twenty-four millions of dollars annually, to eight millions. Even had the Americans possessed the means of building new frigates, the expenditure would have been useless, while Sir John Borlase had the command of the sea. Congress did authorise the commencement of four new seventy-fours, and of four forty-four gun frigates, with six new sloops for the ocean, and as many vessels of every description, as circumstances would show the necessity for, on the lakes.
