In May 1799, Lord Wellesley issued orders from Madras for the advance of forces from Tiruchirappalli, Thanjavur and Madurai to Tirunelveli. Major Bannerman, armed with extensive powers, assumed the command of the expedition. On the 1 September, 1799 the Major served an ultimatum directing Kattabomman to surrender and attend on him at Palayamkottai on the 4th. Kattabomman replied that he would submit on a lucky day.
Bannerman considered this reply as evasive and decided on military action. On 5 September Kattabomman’s fort was attacked. On the 16th reinforcements reached from Palayamkottai. In a clash at Kolarpatti the Palayakkarar troops suffered heavy casualty and Sivasubramania Pillai was taken prisoner. Kattabomman escaped to Pudukkottai. The ruler of Pudukkottai captured Kattabomman from the jungles of Kalapore and handed him over to the British.
Fall of Kattabomman
Bannerman brought the prisoners to an assembly of the Palayakkarars and after a mockery of trial sentenced them to death. Sivasubramania Pillai was executed at Nagalapuram on the 13th of September. On the 16th of October Vira Pandyan was tried before an assembly of Palayakkarars, summoned at Kayattar. In an assertive tone and with contempt for death he admitted the charges levelled against him. Thereupon, Bennerman announced death penalty. On the 17th of October Kattabomman was hanged to death at a conspicuous spot near the old fort of Kayattar. Vira Pandyan faced the last moments of his life with the pride of a hero.
