In April, Rear-admiral Morris was despatched with the advanced squadron and arrived at Wingo Sound about the middle of April, having been previously informed of the state of affairs in Sweden, and instructed to keep up the appearance of hostility without committing any positive act; in the mean time a fleet of line of battle ships was fitting out at Carlscrona, and strict orders were issued that in the event of their putting to sea they were not to be molested by his Majesty's ships. A correspondence was entered into with the Danish auditor-general respecting the exchange of prisoners, in which a demand was made for the release of all the Danish prisoners in lieu of all English, which would have been ten to one in favour of Denmark; but the chief object was the release of a Danish officer, who, after having struck his colours, attempted to destroy his ship, contrary to the laws and usages of war, and who had been detained in consequence. This request was at first refused, but in consequence of the kind treatment of the unfortunate crews who suffered shipwreck, and who were unconditionally liberated, the exchange took place. Sir James hoisted his flag in the Victory on the 14th of April, and on the 28th sailed from the Downs. On the 3rd May he arrived at Gothenburg, having then under his command ten sail of the line, seven frigates, and fourteen smaller vessels. Admiral Morris, with a strong detachment, passed through the Belt to Hanoe, where he carried on the service relating to convoys, and the prevention of troops being sent across the Belt to the Danish islands, which were no doubt intended to menace Sweden into compliance with the demands and views of Buonaparte. This campaign commenced with several brilliant naval actions, among which the following is most worthy of being recorded. During the spring the Danes had succeeded in stationing a large frigate and six large brigs on the coast of Norway, for the purpose of attacking our convoys in passing through the Cattegat, which, in order to protect the trade, had obliged Sir James to station the Dictator of sixty-four guns, and three brigs, off that part of the coast. The result cannot be more fully given than in the following extract of Captain Stewart's letter to Sir James: H.M.S. Dictator, Sleeve, 7th July 1812. SIR, I have the honour to inform you, that yesterday evening being off Mardoe, with the Podargus, Calypso, and Flamer, the mast-heads of the squadron were seen over the rocks, and Captain Robilliard of the Podargus, in the most handsome manner, volunteered to lead the squadron in to attack them, he having a man on board acquainted with the place; and as neither the pilots nor masters of either of the ships conceived themselves equal to the charge, I did not hesitate to accept his kind offer, well knowing the British flag would meet nothing but honour in such hands.
