With undaunted energy he now attempted to get hold of the _South Carolina_, formerly the _Indien_. But the plan failed, and he remained without a vessel. Unable to rest, although his health had for some time been failing, he was given consent to go off with the French fleet under Marquis De Vaudreuil, "in pursuit of military marine knowledge," as he termed his object. Then, in the summer of 1783, came an attack of fever. On his recovery, he was appointed by Congress as agent to collect all moneys due from the sale of prizes taken in European waters under his command. In this work he showed unusual business tact and ability. When the war closed, he began a profitable business in illuminating oils, and continued his activities in securing prize money until all accounts had been settled. Then Paul Jones set off for Copenhagen to collect indemnity from the Danish government for the prizes the mad Landais had delivered to Bergen, and which that country had turned over to England before the declaration of hostilities between the two. He arrived in January, 1788, and was magnificently entertained by the court, being given a pension of 1500 crowns a year "for respect shown to the Danish flag" while he commanded in the European seas. The negotiations for indemnity were suspended and transferred, with his agreement, to Paris. When Paul Jones was in Paris, the Russian ambassador to France made a proposition to him, through Mr. Jefferson, to take a position in the Russian navy. Russia was then at war with Turkey, and the clever Simolin so impressed the Scotch captain with the great deeds he might do for the benefit of the Russian empire and the distress of the Turks, that he at once began to maneuver for the highest command possible. He demurred at the rank of captain-commandant, a rank equal to that of brigadier-general in the present United States army--and maintained that nothing less than that of rear-admiral was fitting. This was allowed. Our hero left Copenhagen on his ill-fated Russian mission, April 11, and made a flying and perilous trip to St. Petersburg. The Baltic was filled with ice blocks, but at the muzzle of his pistols the intrepid Scotchman forced two frightened and unwilling boatmen to row him across the turbulent stream. On April 23 he was presented to the Empress, and she conferred upon him the coveted rank of rear-admiral, to the profound disgust of many of the English officers in the service of Russia, who looked upon the newcomer as a red-handed and infamous pirate.
