In 1774, at the age of 21, Pazhassi Raja took over the throne to replace his uncle who had fled to Travancore. He vowed to resist Hyder Ali's troops, and stayed in Kottayam, where he gathered a force and began guerrilla battles against the troops of Mysore as he had neither guns nor troops enough to face them in an open battle. He set up a large number of bases in the nearly impenetrable forested mountains of Puralimala and Wynad and repeatedly inflicted severe minor losses on the Mysore army in Kottayam as well as in Wynad.
