The news of the capture of Arcot had produced the effect which Clive had anticipated from it. It alarmed and irritated the besiegers of Trichinopoli, and inspired the besieged with hope and exultation. The Mahratta chief of Gutti and the Rajah of Mysore, with whom Muhammud Ali had for some time been negotiating, at once declared in his favour. The Rajah of Tanjore and the chief of Pudicota, adjoining that state, who had hitherto remained strictly neutral, now threw in their fortunes with the English, and thereby secured the communications between Trichinopoli and the coast.
Chunda Sahib determined to lose not a moment in recovering Arcot, knowing that its recapture would at once cool the ardour of the new native allies of the English; and that, with its capture, the last hope of the besieged in Trichinopoli would be at an end. Continuing the siege, he despatched three thousand of his best troops, with a hundred and fifty Frenchmen, to reinforce the two thousand men already near Arcot, under the command of his son Riza Sahib. Thus the force about to attack Arcot amounted to five thousand men; while the garrison under Clive's orders had, by the losses in the defence of the fort, by fever and disease, been reduced to one hundred and twenty Europeans, and two hundred Sepoys; while four out of the eight officers were hors de combat.
The fort which this handful of men had to defend was in no way capable of offering a prolonged resistance. Its walls were more than a mile in circumference, and were in a very bad state of repair. The rampart was narrow and the parapet low, and the ditch, in many places, dry. The fort had two gates. These were in towers standing beyond the ditch, and connected with the interior by a causeway across it. The houses in the town in many places came close up to the walls, and from their roofs the ramparts of the forts were commanded.
On the 23rd September Riza Sahib, with his army, took up his position before Arcot. Their guns had not, however, arrived, with the exception of four mortars; but they at once occupied all the houses near the fort, and from the walls and upper windows kept up a heavy fire on the besieged.
Clive determined to make an effort, at once, to drive them from this position, and he accordingly, on the same afternoon, made a sortie. So deadly a fire, however, was poured into the troops as they advanced, that they were unable to make any way, and were forced to retreat into the fort again, after suffering heavy loss.
On the night of the 24th, Charlie Marryat, with twenty men carrying powder, was lowered from the walls; and an attempt was made to blow up the houses nearest to them; but little damage was done, for the enemy were on the alert, and they were unable to place the powder in effective positions, and with a loss of ten of their number the survivors with difficulty regained the fort.
For the next three weeks the position remained unchanged. So heavy was the fire which the enemy, from their commanding position, maintained, that no one could show his head for a moment, without running the risk of being shot. Only a few sentinels were kept upon the walls, to prevent the risk of surprise, and these had to remain stooping below the parapet. Every day added to the losses.
Captain Clive had a series of wonderful escapes, and indeed the men began to regard him with a sort of superstitious reverence, believing that he had a charmed life. One of his three remaining officers, seeing an enemy taking deliberate aim at him through a window, endeavoured to pull him aside. The native changed his aim, and the officer fell dead. On three other occasions sergeants, who accompanied him on his rounds, were shot dead by his side. Yet no ball touched him.
Provisions had been stored in the fort, before the commencement of the siege, sufficient for sixty days; and of this a third was already exhausted when, on the 14th of October, the French troops serving with Riza Sahib received two eighteen-pounders, and seven smaller pieces of artillery. Hitherto the besiegers had contented themselves with harassing the garrison night and day, abstaining from any attack which would cost them lives, until the arrival of their guns. Upon receiving these, they at once placed them in a battery which they had prepared on the northwest of the fort, and opened fire.
So well was this battery placed, and so accurate the aim of its gunner, that the very first shot dismounted one of the eighteen-pounders in the fort. The second again struck the gun and completely disabled it. The besieged mounted their second heavy gun in its place, and were preparing to open fire on the French battery, when a shot struck it also and dismounted it. It was useless to attempt to replace it, and it was, during the night, removed to a portion of the walls not exposed to the fire of the enemy's battery. The besiegers continued their fire, and in six days had demolished the wall facing their battery, making a breach of fifty feet wide.
