The position was, indeed, a desperate one, and there remained only the alternatives of success against the fort, or total destruction. He determined to attack. All day, his batteries kept up a heavier fire than ever, maintaining an equal fire against all the bastions in order that, if the enemy should obtain any information of the projected attack, they would not know against which point it was directed. Colonel Forde had ascertained that fishermen were in the habit of making their way, across the swamp, to the southwest angle of the fort, that on the sea face opposite to the British frontiers. He determined to effect a diversion, by an attack upon that side; and therefore ordered Captain Knox, with seven hundred Sepoys, to make a detour to cross the swamp, and to attack upon that side. Still further to distract the attention of the garrison, he instructed Anandraz to advance with his men along the causeway, and to open fire against the ravelin. The main attack, which consisted of the rest of the force, composed of three hundred and twenty European infantry, thirty gunners, thirty sailors, and seven hundred Sepoys, was to be delivered against the breach in the bastion, mounting ten guns, in the northeast angle of the fort. At ten o'clock, the force drew up under arms. The fire of the batteries was kept up, much later than usual, in order that the enemy should have no time to repair the breaches. The hour of midnight was fixed for the attack, as at that time the tide was at its lowest, and the water in the ditches round the ramparts not more than three feet deep. Captain Knox and his party started first. The main body should have set out half an hour later, but were detained, owing to the unaccountable absence of Captain Callender, the officer who was to command it. As this officer was afterwards killed, the cause of his absence was never explained. The party started without him, and before they could reach the ditch, they heard the sound of firing from the farther corner of the fort, telling that Knox was already at work. "Shure, yer honor," muttered Tim, as he made his way through the swamp, knee deep, beside his master, "this is worse than the day before Plassey. It was water then, but this thick mud houlds one's legs fast at every step. I've lost one of my boots, already." It was indeed hard work; but at last, the head of the column reached the ditch, just as a fresh burst of firing told that the Rajah Anandraz was attacking the ravelin. The French, in their belief in the absolute security of the place, had taken but few precautions against an attack; and it was not until the leading party had waded, nearly breast high, through the ditch; and began to break down the palisade beyond it, that they were discovered. Then a heavy artillery and musketry fire from the bastions on the right and left was opened upon the assailants.
