But Mahomed Zemaun Khan was the recognised chief of the Barukzye party; and he now asked on what authority the Sirdar ventured without his sanction to make peace with the Suddozyes. There appeared to be every chance of an open rupture between them; and scarcely had Akbar Khan concluded his negotiations with the Prince, then the Newab made a hostile demonstration, attacked the Balla Hissar, but was beaten back with much slaughter. It was, however, currently reported that a secret understanding existed between the two Barukzye chiefs, whose common object it was to obtain possession of the Balla Hissar. Two or three days afterwards they were, outwardly, again united. An attempt had been made to lure the Prince to an interview with Akbar Khan beyond the walls of the Balla Hissar. The Arabs in the garrison, who remained true to the royal family, dissuaded the Prince from exposing himself to the treachery of the Sirdar; mutual distrust soon engendered a rupture between them; and it was plain, that if some arrangement could not be promptly made between the Prince and the Barukzyes, through the agency of the Kuzzilbash chief, the Balla Hissar, the treasure, and the guns, would speedily fall into the hands of Akbar Khan and his confederates. The Barukzyes now laid siege, with redoubled vigour, to the Balla Hissar. The Prince was well-nigh deserted.[229] He called upon Oosman Khan, Shah Soojah’s old minister, to aid him, but upon some frivolous pretext, the Wuzeer declined to league himself with so perilous a cause. It was assiduously given out that the Prince was holding the Balla Hissar only for the Feringhees; and, as the national feeling became stronger and stronger against him, if it had not been for the strength of the place itself, he would hardly have been able to hold it for a day against the Barukzyes. But the fortress held out, in spite of the weakness of the Prince and the garrison; and so at last the Barukzyes began to undermine the works. “Last night,” wrote Futteh Jung to General Pollock, at the beginning of June, “they made an assault; now they have made mines in every direction. My affairs are in a very critical state.... If you do not come quickly, the Balla Hissar and the throne will be lost, and you will be a sufferer. At this time I am at my last gasp. Moreover, there is nothing in the magazine.[230] Now is the crisis.”[231] On the 6th of June, after an ineffectual attempt at negotiation, Akbar Khan issued orders for the springing of the mine. But it was not carried sufficiently far to damage the works.[232] The explosion killed a large number of the besiegers; whilst the storming party was driven back by the garrison with considerable loss. The troops of the Shah-zadah are said to have “behaved very nobly, and like heroes, to have defeated the assault.” Mohun Lal reported, but with some exaggeration, that not less than 1000 of the followers of Akbar Khan fell upon this day.
