Tipu sent a letter on January 19, 1790 to Budruz Zuman Khan. It says:

Don't you know I have achieved a great victory recently in Malabar and over four lakh Hindus were converted to Islam? I am determined to march against that cursed Raman Nair very soon. Since I am overjoyed at the prospect of converting him and his subjects to Islam, I have happily abandoned the idea of going back to Srirangapatanam now.
