NEW YORK. August 25. From Gottenburg.--Capt. Forbes, who arrived this morning from Gottenburg, informs that all the ports of Denmark were shut against American vessels; and that the Danish privateers capture every American they can come across, and that the most of them were condemned under some pretext or other: It was correctly reported at Gottenburg that the emperor of Russia had made propositions to the English to join him in a war against France. A French consul was hourly expected at Gottenburg, when it was supposed all American property would be sequestered. In consequence of this information the American vessels hauled out of the reach of the castle. Capt. Forbes also informs that the high marshal at Gottenburg was taken from his carriage by the people and torn to pieces, on account of a suspicion that he had been accessory to the death of the crown prince. The British consul's functions ceased on the 20th of June, at Gottenburg, by order of the Swedish government. Mr. Robert Dickson, who had usurped the power of acting as American consul, was said to be an agent of the gov. of Anholt, and concerned with him in several privateers. This contributed not a little to exasperate the Danes against the Americans--in consequence of which, it being discovered that the said Dickson had no authority to act as consul, a meeting was held by the Americans in port, and a letter addressed to Mr. D. pointing out the impropriety of opening despatches from our government and likewise the pernicious tendency his conduct would have in administering an office he was in no wise entitled to the possession of. The British admiral on the station refused to give convoy instructions to any but vessels having license, but observed that he conceived himself bound to protect all American vessels that chose to join the convoy, and should protect them accordingly. The Sylph was boarded by the Thamer gun brig and treated politely. It was stated at Copenhagen that Mr. Dickson being possessed of the secret marks of American papers had fabricated registers &c. for English ships.
