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 L1500 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."
