Sir Gore Ouseley returned to England, leaving his secretary, Mr. Morier, in charge of the Mission; but before the treaty was finally accepted, it was modified by the British Government, and Mr. Henry Ellis was despatched to Persia, in 1814, to negotiate these alterations at the Persian Court. A comparison of the treaty, signed by Sir Gore Ouseley, with that which was subsequently accepted, will show that the alterations, which were very considerable in respect of words, were less so in respect of substance. The most important conditions of the treaty are to be found in both documents. But the progress of events had rendered it necessary to expunge certain passages from the treaty negotiated by Sir Gore Ouseley. For example, the 7th article of that treaty provided, that “should the King of Persia form magazines of materials for ship-building on the coast of the Caspian Sea, and resolve to establish a naval force, the King of England shall grant permission to naval officers, seamen, shipwrights, carpenters, &c., to proceed to Persia from London and Bombay, and to enter the service of the King of Persia—the pay of such officers, artificers, &c., shall be given by his Persian Majesty at the rates which may be agreed upon with the English ambassador.”[92] But by the treaty of Goolistan, Persia engaged not to maintain a naval force on the Caspian. The article, therefore, was necessarily expunged. On the 25th of November, the definitive treaty, which was finally accepted, was concluded at Teheran by Messrs. Morier and Ellis. It was declared to be strictly defensive. The plan of defence thus marked out was more extensive than practicable. It bound the Persian Government to engage “not to allow any European army to enter the Persian territory, nor to proceed towards India, nor to any of the ports of that country; and also to engage not to allow any individuals of such European nations, entertaining a design of invading India, or being at enmity with Great Britain, whatever, to enter Persia.” “Should any European powers,” it was added, “wish to invade India by the road of Khorassan, Tartaristan, Bokhara, Samarcand, or other routes, his Persian Majesty engages to induce the kings and governors of those countries to oppose such invasion as much as is in his power, either by the fear of his arms or by conciliatory measures.” In the third article it is laid down, that “the limits of the territories of the two states of Russia and Persia shall be determined according to the admission of Great Britain, Persia, and Russia”—a stipulation of an extraordinary and, perhaps, unexampled character, inasmuch as Russia had not consented to this mode of adjudication. The eighth and ninth articles related to Afghanistan, and are contained in the following words:
