Meanwhile Marthanda Varma of Travancore affected a crushing defeat of the Dutch forces. The rising power of the British and French elsewhere in India declined the strength of the Dutch. After this defeat they never really regained their former power in Kerala. By now the Samoothiri had also distanced himself from them.
 

1745 - Revolt of the Muslims in Tirurangadi against the Nairs and chieftains, which came as a blow to Samoothiri.
 

1757 - Samoothiri managed to lay siege on Chetvai, forcing the Dutch to leave the port.
 

Samoothiri's forces invaded Walluvanad and captured some more areas belonging to the Vellaattiri. Then the triumphant army of Samoothiri entered the territory of the Palakkad Raja. The forces were commanded by Chencheeri Namboothiri. Thousands of people were murdered in the attack. The Palakkad Raja lost the war and had to agree to pay one-fifth of his revenue to Samoothiri as war indemnity.
 

Beginning of Samoothiri's decline of power - After the war Palakkad Raja did not pay the amount agreed to earlier, but sent Kombi Achan to Mysore with an appeal to render military help. The Dalawa of Mysore ordered the Foujdar of Dindigal, Haider Ali, to render military help to the Palakkad Raja. Haider Ali sent his brother-in-law Maqdum Ali with an army of 2000 horses and 5000 infantry. They made surprise attacks on the frightened Nair soldiers of Samoothiri's army and easily put them to flight. The lack of resistance was a pleasant surprise to Mysore army. Samoothiri sued for peace and promised to pay a war indemnity of 12 lakhs. This was accepted and Maqdum returned to Mysore with his army.
