Timur Melek was equally active in the defense of the town. He built a number of flat-bottomed boats, which might be called floating batteries, since they were constructed for throwing missiles of all sorts into the camp of the enemy. These batteries, it is said, were covered over on the top to protect the men, and they had port-holes in the sides, like a modern man-of-war, out of which, not cannon balls and bomb-shells indeed, but arrows, darts, javelins, and stones were projected. The boats were sent out, some on the upper side of the town and some on the lower, and were placed in stations where they could most effectually reach the Mongul works. They were the means of killing and wounding great multitudes of men, and they greatly disturbed and hindered the besiegers' operations. Still Elak persevered. He endeavored to shut up the city on every side as closely as possible; but there was on one side a large morass or jungle which he could not guard, and Timur received a great many re-enforcements, to take the place of the men who were killed on the walls, by that way. In the mean time, however, Elak was continually receiving re-enforcements too from Prince Jughi, who was not at a great distance, and thus the struggle was continued with great fury. At last Timur contrived an ingenious stratagem, by which he hoped to cause his enemy to fall into a snare. It seems that there was a small island in the river, not far from the walls of the city, on which, before the siege commenced, Timur had built a fortress, to be held as a sort of advanced post, and had garrisoned the fortress with about one thousand men. Timur now, in order to divert the attention of the Monguls from the city itself, sent a number of men out from the city, who pretended to be deserters, and went immediately to the Mongul camp. Of course, Elak questioned them about the defenses of the city, in order to learn where the weak points were for him to attack. The pretended deserters advised him to attack this fortress on the island, saying that it could very easily be taken, and that its situation was such that, when it was taken, the city itself must surrender, for it completely commanded the place. So Elak caused his principal engines to be removed to the bank of the river, opposite the island, and employed all his energies and spent all his ammunition in shooting at the fortress; but the river was so wide, and the walls of the fortress wore so thick and so high, that he made very little impression. At last his whole supply of stones--for stones served in those days instead of cannon balls--was exhausted, and as the town was situated in an alluvial district, in which no stones were to be found, he was obliged to send ten or twelve miles to the upland to procure a fresh supply of ammunition. All this consumed much time, and enabled the garrison to recruit themselves a great deal and to strengthen their defenses.
