All vessels and merchandise of whatever nature soever, whenever they shall have been recovered from the hands of pirates on the high seas, shall be brought into some port of one of the two States, and shall be delivered to the care of the officers of the said port, in order to be restored entire to their true proprietor, as soon as he shall have duly and sufficiently proved his property. ARTICLE XIII. The ships of war belonging to the two parties, as also those of their subjects which are armed, shall conduct at full liberty wheresoever they please, the prizes they shall have made from their enemies, without being obliged to pay any other duties than such as the most favored nations; the said vessels or the said prizes, on entering into the ports of his Danish Majesty, or of the said United States, shall not be subject to be stopped or seized, nor shall the officers of the places have any power to take cognizance of the validity of the said prizes, which shall go out, and be freely conducted in full liberty, to the places mentioned in the commissions, which the captains of the said vessels shall be obliged to produce. ARTICLE XIV. In order to favor as much as possible the commerce on both sides, it is agreed, that if a war should happen between his Majesty, the King of Denmark and Norway, and the United States of America, (which God forbid) nine months after the declaration of war shall be granted to the subjects on both sides to collect, sell, and transport freely, the merchandise and effects belonging to them, and to withdraw themselves; and if anything is taken from them, or if any injury is done to them during the above prescribed time, by one of the two parties, full and entire satisfaction shall be given them in this respect. ARTICLE XV. No subject of his Majesty, the King of Denmark and Norway, shall take a commission or letter of marque (to arm any vessel or vessels, for the purpose of acting as a privateer against the said United States, or any of them, or against their subjects, people, or inhabitants, or against their property, or that of any among them) from any Prince whatever, with whom the said United States shall be at war. In like manner no citizen, subject, or inhabitant of the said United States, or of any of them, shall demand or accept of any commission or letter of marque (to arm any vessel or vessels, to cruise against the subjects of his said Majesty, or any of them, or their property) from any Prince or State whatever, with whom his Majesty shall be at war; and if any one of either nation should take such commissions or letter of marque, he shall be punished as a pirate.
