3,000 Brahmins had committed suicide to escape conversion to Islam during Tipu Sultans's rule.
The Mysore Gazetteer says that the ravaging army of Tipu Sultan had destroyed more than 8000 temples in South India.
The world-famous Protuguese traveller, Fr. Barthoelomeo, writes in his book Voyage to East Indies (6): "Tipu was riding on an elephant behind which another army of 30,000 soldiers followed. Most of the men and women were hanged in Calicut, first mothers were hanged with their children tied to necks of mothers. That barbarian Tipu Sultan tied the naked Christians and Hindus to the legs of elephants and made the elephants to move around till the bodies of the helpless victims were torn to pieces. Temples and churches were ordered to be burned down, desecrated and destroyed. Christian and Hindu women were forced to marry Mohammadans and similarly their men (after converting Hindu men into Islam) were forced to marry Mohammadan women. Those Christians, who refused to be honoured with Islam, were ordered to be killed by hanging immediately."
