The demonstration was an insignificant one in itself; but by the time that intelligence of the movement had reached the Persian camp, the expedition, gathering new dimensions at every stage, had swollen into bulk and significance. The most exaggerated reports of the doings and intentions of the British soon forced themselves into currency. The Persian camp was all alive with stories of the powerful British fleet that had sailed into the gulf, destroyed Bunder-Abassy and all the other ports on the coast, taken Bushire, and landed there a mighty army, which was advancing upon Shiraz, and had already taken divers towns in the province of Fars. Nothing could have been more opportune than the arrival of these reports. Mr. M’Neill was making his way towards the frontier, when intelligence of the Karrack expedition met him on the road. About the same time he received letters of instruction from the Foreign-office, issued in anticipation of the refusal of Mahomed Shah to desist from his operations against Herat; and thinking the hour was favourable, he resolved to make another effort to secure the withdrawal of the Persian army, and to regain for the British Mission the ascendancy it had lost at the Persian Court. Fortified by these instructions from the Foreign-office, Mr. M’Neill despatched Colonel Stoddart to the Persian camp, with a message to the Shah. The language of this message was very intelligible and very decided. The Shah was informed that the occupation of Herat or any part of Afghanistan by the Persians would be considered in the light of a hostile demonstration against England; and that he could not persist in his present course without immediate danger and injury to Persia. It was stated, that already had a naval armament arrived in the Persian Gulf, and troops been landed on the island of Karrack, and that if the Shah desired the British Government to suspend the measures in progress for the vindication of its honour, he must at once retire from Herat, and make reparation for the injuries which had been inflicted upon the British Mission.
