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.
