The island of Anholt, which had been garrisoned by seamen and marines under the command of Captain James W. Maurice, of the Royal Navy, was attacked on the 23rd of March by a body of Danish troops, amounting to 1600 men; but they were so well received by the Governor and his brave crew (for the island was on the establishment of a vessel of war) that they were forced to capitulate, with the loss of their leader Major Melstedt, two officers, and 500 of their people in killed, wounded, and prisoners; while Capt. Baker, of the Tartar, and Captain J.P. Stewart, of the Sheldrake, chased and took several of their gun-boats employed on that expedition. Sir James had finished his three years in the Baltic, the time generally prescribed for an Admiral commanding-in-chief to remain on one station, and it was now his turn to have a command in the Mediterranean, which was considered more lucrative; but his conduct during his command in the Baltic had so completely gained the confidence and good-will of the Swedes, and it had now become of such importance to keep them, with such a general as Bernadotte at their head, on good terms, that he was requested to continue on that most important command, as the only chance of accomplishing the desirable object of a Northern coalition. Nothing could be more delicate or more difficult than the situation in which Sir James was now placed, for while it required firmness to uphold the dignity of the empire which he represented, as the only diplomatic functionary as well as commander-in-chief in the North, tact, wisdom, and forbearance were equally indispensable. These qualities Sir James possessed in a superlative degree, and the Author, who from his knowledge of the Swedish language was employed confidentially on all the communications which subsequently took place, can testify that it is to the wise policy of the Admiral that the nation owes the success of these negociations. It is the opinion of Swedish and Russian diplomatists that had Sir James not been employed, the Northern Coalition, which was so fatal to the ambitious views of Buonaparte, never would have taken place; and for such a service no reward which it was in the power of Government to bestow on him would have been too great. There can be no doubt, had the lamented Perceval not met with an untimely end by the hand of an assassin, that he would at the close of 1812 have been rewarded by the Peerage which was so long unaccountably withheld. Sir James was still in London when he received the statement of the discomfiture of the Danish attack on Anholt, a particular account of which may be seen in James's Naval History. The following letters on this gallant affair, which have not yet been published, will be perused with interest. London, 10th April 1811. MY DEAR SIR,
