Tipu Massacred 800 Mandyam Brahmins Melkote on Deepavali.

Tipu ordered his troops to round up all Mandyam Iyengars of Melkote, many of whom were relatives and friends of Tirumaliyengar, and he massacred them in cold blood.

The slaughter was on the day when the Mandyam Iyengars were getting ready to celebrate Naraka Chaturdashi. The celebrations turned into mourning.
