Three Swedish frigates, as Baron de Lagerbjelke gave me to understand, have been ordered round from Carlscrona to cruise off these coasts; and 106 gun-boats, hemmemas, and other vessels, are at present in or near the water; but the want of men from the mortality of the last winter is severely felt, and can only be supplied from the south, in case you think fit to coincide with the views of this government. I have, &c. &c. &c. AUGT. FOSTER. Vice-admiral Sir James Saumarez, Bart, and K.B. &c. &c. &c. This was the first communication which had been made by the Swedish government since Gustaf IV. Adolf was deposed, and his uncle had accepted the regency with full powers. By this _expose_ it appears that their first act after the revolution was to try to make peace singly with Buonaparte, which was of course refused; because the Swedes could give him nothing in return, and shutting the ports against Great Britain was a preliminary that could not be dispensed with. There was no alternative therefore but to apply to England for protection against their inveterate enemies the Russians, who had already possessed themselves of all Finland, and were preparing for the invasion of Sweden. Mr. Foster added the following private opinion on the state of affairs, which now became so interesting: Stockholm, 15th May 1809. SIR, I have written you a long public letter upon the wishes of this government for your co-operation in the defence of Sweden. My private opinion is, that the Swedes, in addition to their desire to maintain their commercial relations with us, (which of course they wish should be still carried on, though by secret understanding,) entertain the design of preventing the Russians from interfering in their interior concerns; they also hope the French may be ultimately victorious against Austria, as they suppose they will not be inclined to the confirming of Russia in her conquest of Finland; which considerations make this government so backward in accepting the terms proposed by Russia. In the mean time they are in a most deplorable state, and cannot, I believe, collect 10,000 men: without your assistance they must perish or yield; with your aid it will be but a respite, I dare say, but perhaps of use for the Swedes. The news of to-day is rather better: on the Tagliamento it would appear the Austrians are victorious; and in Poland, where Colonel Marfeld is said to have cut off some Russians, marched on Warsaw, and to be about besieging Dantzic: these latter want confirmation. The French, I fear, have crossed the Inn, but with great loss. I have, &c. &c. &c. AUGT. FOSTER. Vice-admiral Sir James Saumarez, Bart. and K.B. &c. &c. &c.
