II. It is agreed that the preliminary articles, formed with the hand of truth and sincerity, shall not be changed or altered, but there shall arise from them a daily increase of friendship, which shall last for ever between the two most serene Kings, their heirs, successors, their subjects, and their respective kingdoms, dominions, provinces, and countries.
III. His Majesty the King of Persia judges it necessary to declare that from the date of these preliminary articles, every treaty or agreement he may have made with any one of the powers of Europe, becomes null and void, and that he will not permit any European force whatever to pass through Persia, either towards India, or towards the ports of that country.
IV. In case any European forces have invaded, or shall invade, the territories of His Majesty the King of Persia, His Britannic Majesty will afford to His Majesty the King of Persia, a force, or, in lieu of it, a subsidy with warlike ammunition, such as guns, muskets, &c., and officers, to the amount that may be to the advantage of both parties, for the expulsion of the force so invading; and the number of these forces, or the amount of the subsidy, ammunition, &c., shall be hereafter regulated in the definitive treaty. In case His Majesty the King of England should make peace with such European power, His Britannic Majesty shall use his utmost endeavours to negotiate and procure a peace between His Persian Majesty and such power. But if (which God forbid) His Britannic Majesty’s efforts for this purpose should fail of success, then the forces or subsidy, according to the amount mentioned in the definitive treaty, shall still continue in the service of the King of Persia as long as the said European forces shall remain in the territories of His Persian Majesty, or until peace is concluded between His Persian Majesty and the said European power. And it is further agreed, that in case the dominions of His Britannic Majesty in India are attacked or invaded by the Afghans or any other power, His Majesty the King of Persia shall afford a force for the protection of the said dominions, according to the stipulations contained in the definitive treaty.
V. If a detachment of British troops has arrived from India in the Gulf of Persia, and by the consent of His Persian Majesty landed on the Island of Karrak, or at any of the Persian ports, they shall not in any manner possess themselves of such places; and, from the date of these preliminary articles, the said detachment shall be at the disposal of His Majesty the King of Persia, except his Excellency the Governor-General of India judges such detachment necessary for the defence of India, in which case they shall be returned to India, and a subsidy, in lieu of the personal services of these troops, shall be paid to His Majesty the King of Persia, the amount of which shall be settled in the definitive treaty.
VI. But if the said troops remain, by the desire of His Majesty the King of Persia, either at Karrak, or any other port in the Gulf of Persia, they shall be treated by the Governor there in the most friendly manner, and orders shall be given to all the Governors of Farsistan, that whatever quantity of provisions, &c., may be necessary, shall, on being paid for, be furnished to the said troops at the fair prices of the day.
VII. In case war takes place between His Persian Majesty and the Afghans, His Majesty the King of Great Britain shall not take any part therein, unless it be at the desire of both parties, to afford his mediation for peace.
VIII. It is acknowledged the intent and meaning of these preliminary articles are defensive. And it is likewise agreed, that as long as these preliminary articles remain in force, His Majesty the King of Persia shall not enter into any engagements inimical to His Britannic Majesty, or pregnant with injury or disadvantage to the British territories in India.
This treaty is concluded by both parties, in the hope of its being everlasting, and that it may be productive of the most beautiful fruits of friendship between the two most serene Kings.
