During this time the fire of the batteries in front had been unceasing, and had destroyed most of the houses which formed the connecting line between the barricades. Each night, however, the besieged worked to repair damages, and to fill up the gaps thus formed with piles of stones and beams, so that, by the end of the fourth day after the repulse of the first assault, a line of barricades stretched across the line of defence. The enemy, this time, prepared to attack by daylight, and early in the morning the whole army of the nizam marched to the assault. Heedless of the fire of the castle, they formed up in a long line of heavy masses, along the slope. One huge column moved forward against the main breach, two advanced obliquely towards the great gaps in the walls on either side. The latter columns were each headed by bodies of French troops. In vain the guns of the fort, aided by those of the battery on the hill, swept them. The columns advanced without a check until they entered the breaches. Then a line of fire swept along the crest of the barricade from end to end, and the cannon of the besieged roared out. Pressed by the mass from behind, the columns advanced, torn and rent by the fire, and at last gained the foot of the barricade. Here, those in front strove desperately to climb up the great mound of rubbish, while those behind covered them with a storm of bullets aimed at its summit. More than once the troops of the rajah, rushing down the embankment, drove back the struggling masses, but so heavily did they suffer from the fire, when they thus exposed themselves, that Charlie forbade them to repeat the attempt. He knew that there was safety behind, and was unwilling that his brave fellows should throw away their lives. In the centre of the position the native troops, although they several times climbed some distance up the barricade, were yet unable to make way. But the French troops at the flanks were steadily forcing their way up. Many had climbed up by the ruins of the wall, and from its top were firing down on the defenders of the barricade. Inch by inch they won their way up the barricade, already thickly covered with dead; and then Charlie, seeing that his men were beginning to waver, gave the signal. The long blast of a trumpet was heard even above the tremendous din. In an instant the barricades were deserted, and the defenders rushed into the houses. The partition walls between these on the lower floors had already been knocked down, and without suffering from the heavy fire which the assailants opened, as soon as they gained the crest of the barricade, the defenders retreated along these covered ways until in rear of the second line of defence.
