VIII. “Should the Afghans be at war with the British nation, his Persian Majesty engages to send an army against them, in such manner, and of such force, as may be concerted with the English Government. The expenses of such an army shall be defrayed by the British Government, in such manner as may be agreed upon at the period of its being required.” IX. “If war should be declared between the Afghans and Persians, the English Government shall not interfere with either party, unless their mediation to effect a peace shall be solicited by both parties.”[93] One more clause of the definitive treaty calls for notice in this place. In Article VI., it is covenanted that “should any European power be engaged in war with Persia, when at peace with England, his Britannic Majesty engages to use his best endeavours to bring Persia and such European power to a friendly understanding.” “If however,” it is added, “his Majesty’s cordial interference should fail of success, England shall still, if required, in conformity with the stipulations in the preceding articles, send a force from India, or, in lieu thereof, pay an annual subsidy (200,000 tomauns) for the support of a Persian army, so long as a war in the supposed case shall continue, and until Persia shall make peace with such nation.” By this article we, in effect, pledged ourselves to support Persia in her wars with Russia, even though we should be at peace with the latter state. By the convention of Goolistan, it is true that amicable relations had been re-established between the Russian and Persian Governments; but these relations were likely at any time to be interrupted; and it was not difficult to perceive, that, before long, the aggressive policy of Russia would again bring that state into collision with its Persian neighbour. The article, in reality, exposed us at least to the probability of a war with Russia; and laid down the doctrine that every future aggression of the latter against the dominions of the Persian Shah was to be regarded in the light of a hostile demonstration against our Indian possessions.
