By Letters received from Captain Douglas, of His Majesty's Ship Isis, dated at Quebec the 26th and 27th of last Month, it appears, That immediately after raising the Siege of Quebec, of which he gave an Account ー in his Letters of the 8th and 15th of May, every proper Measure was taken to facilitate the farther Operations against the Rebels, by sending down the River all the Pilots which could be procured to bring up the Transports that were daily expected with General Burgoyne from England and Ireland; and, that no Time might be lost on their Arrival, he had provided Pilots for the upper River, and placed Frigates and Armed Vessels in proper Stations to assist and escort them; and also, lest the Transports should be prevented by contrary Winds from sailing up the River, he had stationed Vessels with Provisions at prbper Places, for the Use of the Troops, if they should be obliged to disembark and march by Land. By these Dispositions, all the Transports with Troops which had Pilots on Board, proceeded up the River without stopping at Quebec, and arrived at Three Rivers Time enough to defeat the Rebels, and afterward drive them from St. John's and all their Posts below Lake Champlain. Captain Douglas in the same Letter says, that the prudent and spirited Behaviour of Captain [Henry] Harvey, of the Martin Sloop, cannot be too much commended; and that the Zeal, Vigour, and Unanimity, of His Majesty's Servants on both Elements were scarcely equalled on any other Occasion within his Remembrance. He also writes that he was, in Concert with General Carleton, considering upon a proper Establishment for Armed Vessels to be employed on the Lakes Champlain and Ontario, and in contriving the most expeditious Means of getting them, with other Craft on the said Lakes, in order to the petter accelerating the Passage of the Army; and that Captain Harvey, of the Martin, was returning to Sorel, in order to examine into the Means of floating between Camels (as is practised in Russia and Holland) through the Rapids of Chamble into Lake Champlain, the Six Armed Vessels, one of which was already arrived from England, and the others hourly expected.

By a Letter received from Vice-Admiral Young, dated at Antigua the 31st of May last, it appears, that Captain [Henry] Bryne, of His Majesty's Ship the Hind, which had been sent on Service to St. Augustine in the Province of Georgia, having Intelligence that the Rebels were fitting Armed Vessels in the adjacent Rivers, and being at Anchor off Sunbury River, he ordered Lieutenant [Alexander] Ellis, of the Hinchinbrooke Armed Schooner, with the ship's Tender and Boats, mann'd and arm'd, to proceed over the Bar, where they set on Fire a Brig that was loading, and a Ship on the Stocks, intended by the Rebels for a Privateer to carry 20 Guns. It further appears from the Admiral's aforementioned Letter, that since the Account transmitted in his Letter of the 3d of March, and published in the Gazette of the 8th of last Month, the Cruizers under his Command had seized Seventeen more Ships and Vessels, either belonging to or employed in carrying on a Trade with His Majesty's Rebellious Subjects in North America.
