Mysorean garrisons were trapped by Nair rebels who seized the countryside and ambushed Mysore convoys and communications with great success. The following year, the English East India Company, under Captain Thomas Henry, sieged the Sultan Bathery Fort  to interrupt the supply of arms to Arakkal Kingdom, with a promised help from local kingdoms. But the British were forced to retreat in the retaliation. Mysore army retreated from Malabar temporarily in 1768, successfully crushing the uprisings and building the strategic Palakkad Fort. The authority over Kolathunad was now given to the Arakkal Kingdom. Skirmishes between Arakkal and the Company continued, and in 1770, the Company reclaimed Randattara.

So, again in the Malabar came under the direct Mysore authority.
