"The next day Rajah Sahib was joined by 2000 men from Vellore, commanded by Mortaza Ali in person; and took possession of all the avenues leading to the fort, which seemed little capable of sustaining the impending siege. Its extent was more than a mile in circumference; the walls were in many places ruinous; the rampart too narrow to admit the firing of artillery; the parapet low and slightly built; several of the towers decayed, and none of them capable of receiving more than one piece of cannon; the ditch was in most places fordable, in others dry, and in some choked up; there was between the walls of the fort and the ditch a space, about ten feet broad, intended for a fausse-braye; but this had no parapet at the scarp of the ditch. The fort had two gates, one to the north-west, the other to the east: both of them were large piles of masonry, projecting forty feet beyond the walls; and the passage from these gates was, instead of a drawbridge, a large causeway crossing the ditch. The garrison had, from their arrival, employed themselves indefatigably to remove and repair as many of these inconveniences and defects as the smallness of their number could attend to. They had endeavoured to burn down several of the nearest houses, but without success; for these, having no wood-work in their construction, excepting the beams which supported the ceiling, resisted the blaze; of these houses the enemy's infantry took possession, and began to fire upon the ramparts, and wounded several of the garrison before night, when they retired. At midnight Ensign Glass was sent with two men, and some barrels of gunpowder, to blow up the two houses which most annoyed the fort. This party was let down by ropes over the wall, and, entering the houses without being discovered, made the explosion, but with so little skill, that it did not produce the intended effect. At their return, the rope by which Ensign Glass was getting into the fort broke, and he was by the fall rendered incapable of further duty; so that, at the beginning of the siege, the garrison was deprived of the service of four of the eight officers who set out on the expedition; for one was killed, two wounded, and another returned to Madras; and the troops fit for duty were diminished to 120 Europeans and 200 sepoys; these were besieged by 150 Europeans, 2,000 sepoys, 3,000 cavalry, and 5,000 peons.
"The store of provisions in the fort was only sufficient to supply the garrison sixty days, which rendered it necessary to send away all the inhabitants, excepting a few artificers; and the enemy permitted them to pass through their guard without molestation. Amongst those who remained was a mason, who had been for many years employed in the fort. He gave information that there was an aqueduct under ground, known to very few, but which, if discovered by the enemy, would enable them to drain the only reservoir of water in the fort. The man was rewarded for this seasonable intelligence, and employed to prevent the mischief by choking up a part of the aqueduct within the walls. For fourteen days the enemy, not yet furnished with battering cannon, carried on the siege by firing from the houses with musketry, and a bombardment from four mortars. The bombardment did but little damage; and, to avoid the effect of the musketry, none of the garrison were suffered to appear on the ramparts, excepting the few immediately necessary to avoid a surprise; but, notwithstanding this precaution, several were killed, and more wounded: for the enemy, secure in the houses, and firing from resting-places, took such excellent aim, that they often hit a man when nothing but his head appeared above the parapet; and in this manner three serjeants were killed, who at different times singly accompanied Captain Clive in visiting the works. Mortaza Ali, a few days after his arrival, pretended to be dissatisfied with Rajah Sahib, and removed his troops to a different part of the city, from whence he sent a messenger inviting the garrison to make a sally on the quarters of Rajah Sahib, in which he offered to assist them with his whole force. Captain Clive mistrusted his professions; but, considering the advantage of keeping such a number of the enemy's troops inactive, pretended to approve of the proposal, and carried on for several days a correspondence, until Mortaza Ali, suspecting his scheme was detected, rejoined the army.
"On the 24th of October, the French troops received from Pondicherry two eighteen-pounders, and seven pieces of smaller calibre, and immediately opened a battery to the north-west, which was so well served, that their very first shot dismounted one of the eighteen-pounders in the fort, and the next entirely disabled it. The garrison mounted the other eighteen-pounder; and this, after a few shot, was likewise dismounted; after which, it was employed only in such parts of the fort, where it was not exposed to the enemy's artillery. The three field-pieces were likewise cautiously reserved to repulse the enemy when they should storm; so that their battery, firing without much opposition, in six days beat down all the wall lying between two towers, and made a practicable breach of fifty feet.
"In the meantime, the garrison were employed in making works to defend it. A trench was dug just under the rampart, and behind that, at some distance, another; both of which were scattered with crows'-feet, and behind them the walls of a house were pulled down to the height of a breast-work, from whence a row of palisadoes was carried along on each end of both trenches, and continued up the rampart to the parapet. A field-piece was planted on one of the towers which flanked the breach without, and two small pieces of cannon on the flat roof of a house within the fort, opposite to the entrance. In these employments, as, indeed, in all others, the officers contributed their labour equally with the common men; and the enemy, informed of these preparations to defend the breach, did not think it safe to attack it before they had made another. They had by this time burst one of their eighteen-pounders, and removed the other, with one nine-pounder, to a battery which they erected to the south-west.
"The garrison, intending to convince Rajah Sahib that they were in a condition to execute even labours not indispensably necessary, thickened the highest tower of the ramparts, and then raised on the top of it a mound of earth, to such a height as commanded the palace, over the interjacent houses. On the top of this mound they hoisted a vast piece of cannon, sent, according to the tradition of the fort, from Delhi, by Aurungzebe, and said to have been drawn by 1000 yoke of oxen. There were several iron balls belonging to it, each weighing seventy-two pounds. The cannon was laid on the mound, and loaded with thirty pounds of powder, which was fired by a train carried to a considerable distance on the ground. The shot went through the palace, to the no small terror of Rajah Sahib and his principal officers; and, as this was the only effect intended, the cannon was fired only once in the day, at the time when the officers assembled at the head-quarters: on the fourth day it burst.
"The enemy, as if they intended to retaliate this affront, filled up a large house, which commanded the eastern gate, with earth well rammed down, and upon this base raised a square mound of earth to such a height as commanded not only the gate, but likewise every part within the fort. From hence, they intended to fire on the rampart with musketry and two small pieces of cannon. They were suffered to go on with their work until they had completed it and mounted the cannon; when the garrison began to fire from the reserved eighteen-pounder, and in less than an hour, the mound gave way, and tumbled at once, with fifty men stationed on it, some of whom were killed, and many disabled.
"Notwithstanding the numbers of the enemy's guards which surrounded the fort, the garrison, by means of able spies, carried on a constant correspondence with Madras and Fort St. David; where the Company's agents were very solicitous to relieve them; and, having received some recruits from Europe, formed a party of 100 Europeans, who, with 200 sepoys, set out from Madras under the command of Lieutenant Innis. Before they had advanced thirty miles on their way to Arcot, they were surrounded in the town of Trivatore by 2000 of Rajah Sahib's troops, detached with twenty Europeans, and two field-pieces from the city. The English party, having no cannon, were so severely annoyed by the enemy's, that Lieutenant Innis, as the only resource, made a push with all his Europeans to drive them from their guns. The attempt succeeded, but not without a sharp contest, in which twenty of the English, and two of their officers were killed, and a greater number wounded. This loss deterred the rest from continuing their march, and they retreated to Poonamalee, a fort built by the Moors, and at this time belonging to the Company, fifteen miles west of Madras.
"On the 24th of October, the enemy opened their battery to the south-west. The part of the wall against which they directed their fire, was in a very ruinous condition; but it had the advantage of being much less exposed than any other to the fire from the houses. The garrison, therefore, kept up a constant fire of musketry against the battery, and several times drove the enemy out of it; but the breach, notwithstanding, increased every day.
"The retreat of Lieutenant Innis left the garrison little hopes of succour from the settlements; but at this time their spirits were raised by the hopes of other resources. A body of 6000 Mahrattas, under the command of Morari-row, had lain for some time encamped at the foot of the western mountains, about thirty miles from Arcot: they had been hired to assist Mahommed-Ali, by the king of Mysore; but the retreat of the English and the Nabob's troops to Trichinopoly, had been represented in the neighbouring countries so much to their prejudice, that the Nabob's affairs were thought to be desperate, and his allies were suspected of having little intention to support him; and from this persuasion the Mahrattas remained inactive. Captain Clive had found means to send a messenger to inform them of his situation, and to request their approach to his relief. The messenger returning safe to the fort, brought a letter from Morari-row, in which he said he would not delay a moment to send a detachment of his troops to the assistance of such brave men as the defenders of Arcot, whose behaviour had now first convinced him that the English could fight.
"Rajah Sahib, receiving intelligence of their intentions, sent a flag of truce on the 30th of October, with proposals for the surrender of the fort. He offered honourable terms to the garrison, and a large sum of money to Captain Clive; and, if his offers were not accepted, he threatened to storm the fort immediately, and put every man to the sword.
