The prisoners made respectively, by the arms of his Britannic Majesty, and the United States, by sea and by land, not already set at liberty, shall be restored reciprocally and _bona fide_, immediately after the ratification of the definitive treaty, without ransom, and on paying the debts they may have contracted during their captivity; and each party shall respectively reimburse the sums, which shall have been advanced, for the subsistence and maintenance of the prisoners, by the sovereign of the country where they shall have been detained, according to the receipts and attested accounts, and other authentic titles, which shall be produced on each side. ARTICLE III. His Britannic Majesty shall employ his good offices and interposition with the King or Emperor of Morocco or Fez, the Regencies of Algiers, Tunis and Tripoli, or with any of them, and also with every other Prince, State or power of the coast of Barbary, in Africa, and the subjects of the said King, Emperor, States and powers and each of them, in order to provide as fully and efficaciously as possible for the benefit, conveniency and safety of the said United States and each of them, their subjects, people and inhabitants, and their vessels and effects, against all violence, insult, attacks or depredations on the part of the said Princes and States of Barbary, or their subjects. ARTICLE IV. If war should hereafter arise between Great Britain and the United States, which God forbid, the merchants of either country then residing in the other, shall be allowed to remain nine months to collect their debts and settle their affairs, and may depart freely, carrying off all their effects without molestation or hinderance. And all fishermen, all cultivators of the earth, and all artisans and manufacturers unarmed and inhabiting unfortified towns, villages or places, who labor for the common subsistence and benefit of mankind, and peaceably follow their respective employments, shall be allowed to continue the same, and shall not be molested by the armed force of the enemy in whose power, by the events of war, they may happen to fall; but if anything is necessary to be taken from them, for the use of such armed force, the same shall be paid for at a reasonable price. And all merchants or traders with their unarmed vessels employed in commerce, exchanging the products of different places and thereby rendering the necessaries, conveniences and comforts of human life more easy to obtain, and more general, shall be allowed to pass freely unmolested. And neither of the powers, parties to this treaty, shall grant or issue any commission, to any private armed vessels, empowering them to take or destroy such trading ships, or interrupt such commerce.
