Although money was subordinate, in Jones's mind, to glory and the opportunity for action, he was an excellent business man. His commercial transactions had been successful enough to enable him to pay with his own resources the crews of the Alfred and Providence, so that when he set sail in the Ranger he had advanced £1500 to the United States. After the close of the war, at a period of comparative inactivity, he began a profitable trade in illuminating oils, and in his character as prize money agent he continued to show his business dexterity. He began a long campaign of a year of most pertinacious and vigorous dunning for money due the United States, himself, and the officers and sailors under his command. He wrote innumerable letters to Franklin, to de Castries, the new Minister of Marine, to de Vergennes, Minister of Foreign Affairs; to many others, and prepared for the king a careful account of his cruises, in order to show that prize money was due. In arguing for all that he could get he showed great acuteness, legal sense, and, beyond everything, invincible determination. He also again demonstrated his happy talent for abuse of those who stood in his way. He finally secured the allowance of his claims; and the settlements, which began in January, 1784, were completed, as far as France was concerned, in July, 1785. He was paid 181,000 livres, which he turned over, less deductions for expenses and his own share of the prize money, to Thomas Jefferson, then minister to France, who approved the account. Jones charged for his ordinary expenses, however, the sum of 48,000 livres and his share of prize money was 13,000 livres, a total of 61,000 livres, a generous allowance. One of the free-handed man's biographers, A. S. MacKenzie, pointed out that Jones "charged his shipmates for his expenses, during less than two years, more than General Washington did the people of the United States throughout the Revolutionary War."

The next public business of Jones was to attempt to collect indemnity from the Danish government for the delivery to England of the prizes sent by the mad Landais, during Jones's most famous cruise, to Bergen, Denmark. He delayed his trip to Copenhagen, however, for a number of reasons. At this time he was carrying on several private business enterprises of importance, was occupied with society in London and Paris, and was eagerly desirous of being sent by the French government against the Dey of Algiers, who held in bondage many Christians. At various times during his career Jones showed a keen sense of the wrongs inflicted on Americans by the Barbary pirates in search of tribute, and in his letters to Jefferson and others he often suggested plans for their extermination. For de Vergennes and de Castries he prepared a memorandum urging the necessity of a movement against the pirates, and ably pointing out the good that would accrue therefrom to the world, and particularly to France, to which nation he attributed future dominion in North Africa, provided action was taken in time to forestall Great Britain.

"The knowledge of the race persuades me," he wrote, "that England will soon invade the Mediterranean—doubtless as soon as she recovers from the exhaustion of the late war."

The United States, however, were after the war lacking so completely in resources that a war with the pirates was impossible, and France was on the brink of her great Revolution, and had more important things to consider. So Jones died before the expedition for which he had so ardently hoped, and which brought so much honor, as he had predicted, to the man who commanded it—Commodore Dale, once Jones's first lieutenant on the Bonhomme Richard—was dispatched.

Jones finally set off for Copenhagen to collect the indemnity from the Danish government; but hearing of a crisis in an important business matter in which he was interested, he made, before arriving at his destination, a flying trip to America. While there, he was awarded a gold medal by Congress, and said in his journal that such a medal had been given to only six officers.

"To General Washington, for the capture of Boston; General Gates, for the capture of Burgoyne's army; General Wayne, for the taking of Rocky Point;... General Morgan, for having defeated and destroyed a detachment of 1100 officers and soldiers of the best troops of England, with 900 militia merely; General Greene, for having scored a decisive victory on the enemy at Euta Spring.... But all these medals, although well merited, were given in moments of enthusiasm. I had the unique satisfaction of receiving the same honor, by the unanimous voice of the United States assembled in Congress, the sixteenth October, 1787, in memory of the services which I rendered eight years earlier."

It was not until January, 1788, that Paul Jones arrived at Copenhagen, where, during his short stay, he was magnificently entertained by the court. The negotiations for the indemnity, which he began almost immediately, were abruptly terminated by the transfer of the matter for settlement to Paris. Jones, on the day he agreed to suspend the negotiations, received from the Danish government a patent for a pension of 1500 crowns a year, "for the respect he had shown the Danish flag while he commanded in the European seas." Jones kept this transaction, for which he possibly felt ashamed, to himself, until several years afterwards, when, writing to Jefferson, he said: "I have felt myself in an embarrassing situation, with regard to the king's patent, and I have not yet made use of it, though three years have elapsed since I received it."

On Jones's return to Paris from America, previous to his Copenhagen trip, the Russian ambassador to France, Baron Simolin, had made, through Mr. Jefferson, a proposition looking to the appointment of the conqueror of the Serapis to a position in the navy of Russia, then about to war with the Turks. Simolin wrote Catherine II. of Russia that, "with the chief command of the fleet and carte blanche he would undertake that in a year Paul Jones would make Constantinople tremble." This exciting possibility was no doubt constantly in Jones's mind while he was at Copenhagen, and probably increased his willingness to dismiss the indemnity negotiations. He began immediately to manœuvre for the highest command possible. He demurred to the rank of captain-commandant, equal to that of major-general in the army, and maintained that nothing less than rear-admiral was fitting. He laid the account of all his deeds and honors before the dazzled Russian minister at Copenhagen, and said: "The unbounded admiration and profound respect which I have long felt for the glorious character of her Imperial Majesty, forbids the idea that a sovereign so magnanimous should sanction any arrangement that may give pain at the outset to the man she deigns to honor with her notice, and who wishes to devote himself entirely to her service." In order to be in a better position for extorting honors from the empress, Jones wrote Jefferson suggesting that Congress bestow upon him the rank of rear-admiral; and took occasion to assert, on the eve of taking service under a despot, the undying character of his love for America.

"I am not forsaking," he wrote, "the country that has had so many distinguished and difficult proofs of my affection; and can never renounce the glorious title of a citizen of the United States" [Italics are Jones's].
