But though apparently both parties had at last arrived at an understanding, that evening the aspect of affairs became more warlike than ever. The Persian trenches were filled with men, the bodies of horse and foot on the line of investment were strengthened, and there were all appearances that an assault would be made that evening; and the Afghan chiefs were called together and each had his post assigned to him. But scarcely had they separated when Mr. M'Neill himself arrived. He was conducted at once to Kamran's palace, and the greater part of the night was spent in discussion. It was nearly dawn when the minister accompanied Pottinger to the latter's residence. As he had arranged when he arrived that he would sleep at Pottinger's, a room had been prepared for him, Angus sat up for several hours, but then feeling sure that the minister would at once retire to bed on his return, had lain down. When he awoke it was half-past six, and dressing hastily he went into the sitting-room that he shared with Pottinger, and to his surprise found Mr. M'Neill writing there. The minister greeted him cordially.

"I heard all about you from Colonel Stoddart, and approve highly of your remaining here to give Pottinger what aid you can during the siege. I also think that you have done very wisely in determining, as Pottinger told Stoddart you had done, to go to India. I myself will write to the English government saying what you have done, how intelligently you carried on your work at the mission, and recommending you for an appointment on the northern frontier either with the army or the resident at Scinde, or perhaps better still, with Mr. Burnes at Cabul."

At this moment Pottinger entered the room, and he was as surprised as Angus had been at seeing the minister at work after only a couple of hours in bed. There was another meeting with Kamran, who placed himself entirely in the hands of the British envoy, and said that he would gladly consent to any terms agreed upon by him. At the conclusion of the meeting Mr. M'Neill returned at once to the Persian camp.

To the disappointment of all, Major Todd rode in two days later with the surprising news that the Shah had entirely changed his attitude, and absolutely refused to submit the dispute to British arbitration, and that unless the whole people of Herat acknowledged themselves his subjects, he would take possession of the city by force of arms. This sudden change was the result of the arrival of the Russian representative, Count Symonwich, on the morning of the day of M'Neill's visit to the city. The Russian party at once became ascendant. He himself took the conduct of the operations of the siege, the officers with him taught the Persian soldiers how to construct batteries, and Russian money was freely distributed among them. Pottinger's task of explaining to Kamran the news brought by Major Todd was an unpleasant one; but the old man took the news quietly, and said that he never expected anything else, for the Persians had always been noted for their treachery and want of faith. The news, however, caused great discouragement in the town, and it was determined at a meeting of the chiefs that they would send to the Russian ambassador and place themselves under the protection of his master. Meeting after meeting was held, at all of which Pottinger was present. Sometimes he was received and listened to with respect, and other times he was treated with marked discourtesy.

The influence of Mr. M'Neill at the Persian court declined rapidly, while that of the Russians became supreme. For some months past he had failed to obtain any satisfaction for matters of serious complaint. As far back as October a courier bearing despatches from Colonel Stoddart to him at Teheran had been seized by a Russian officer, stripped and imprisoned by the Persians, and his despatches taken from him. The British resident in the Persian Gulf had been grossly insulted by the governor of Bushire, and the Persian government had continued to evade its obligations under the commercial treaty between the two nations. So marked was the indignity with which M'Neill was now treated in the Persian camp, that on the 7th of June he left it with Colonel Stoddart and all his suite and attendants, a step equivalent to a rupture of the relations between Great Britain and Persia.

In the meantime the pressure of famine and sickness became more and more intense in Herat. The city was altogether without drainage, and the stench from the bodies of those who had died or been killed, and of the dead animals, was dreadful. But although much depressed, the courage of the Afghans still sustained them, and when on the 13th of June the Persians surprised the outer works, they held the connecting passage and defended it until assistance came, when the garrison poured out, rushed down the slope, and dislodged the assailants with much slaughter. Another attempt on the same day at a fresh point was equally unsuccessful, and the storming party were twice repulsed. Pottinger was now armed with an authority that he had not before possessed, for he had been appointed by M'Neill British envoy at Herat. The news of the departure of the embassy, and Pottinger's assurances that this was a prelude to war between England and Persia, had but little effect. It was certain that the city could not possibly hold out many weeks, and it might be months before the arrival of a British fleet and army could influence the Persians.

Happily, however, Lord Auckland, Governor-General of India, had not waited for instructions from home, but at the news of the investment of Herat, and the outrage upon our resident in the Persian Gulf, had begun to take steps early in the spring; and on the 4th of June two transports and some vessels of war left Bombay harbour with detachments of two British regiments and a marine battalion, and on the 19th anchored off the island of Karrack in the Persian Gulf.

Upon the 24th of June Herat went through the most terrible experience of the siege. At daybreak a heavy fire opened from the Persian batteries on all four sides of the city. It ceased suddenly after a time. Pottinger, who was at breakfast, exclaimed to Angus, as he leapt up from his seat: "They are going to assault; the batteries have done their work. Quick, to the wall!"

Warning the soldiers they came upon as they ran, they made their way to the wall. Just as they arrived there another gun was fired, and at the signal the batteries on all sides again broke into life. A storm of rockets carried dismay into the town, the mortars dropped their shells into it, and most conclusive of all, a rattle of musketry broke out, growing every moment in power. Against five points was the assault directed. That on the gate of Candahar was repulsed, and the enemy chased back to their trenches. That upon the south-west angle was but a feint, and was never pushed home against the western gate. The Russian regiment under Sampson, and a strong force under a Persian officer, pressed up to the breach; but the Persian was killed and Sampson carried off wounded, and the troops fled after suffering immense loss. The attack on the north-western face was similarly repulsed, but the fifth contest was desperate. The storming party gained the fausse braye. The Afghans defending it fought desperately, and all fell at their post. The storming party rushed up the slope. The officers and leading men were mown down by a heavy musketry fire, but after a fierce struggle the upper fausse braye was carried, and some of the assailants gained the head of the breach.
