reward for the services of Dumas. In the following year
(I740) Dumas took a still more striking part in politics.
After the battle of Damalcheruvu on May I9, I740, in which
Dost Alt, the Nawab of the Carnatic, was defeated and
slain by the Marathas, he received within the walls of Pondi-
cherry the families of the late Nawab and of his son-in'
law Chanda Sahib. He resisted all the menaces of tha-
Marathas to induce him to surrender the fugitives, and his
conduct was reported at Delhi. The Mughal emperor resolved
to recognize his conduct by creating Dumas a Nawab, and
giving him the title of commander of 4,500 horse. This rank
and title Dumas obtained permission to transfer to his
successor, Dupleix, who took over the Governorship of Pondi-
cherry in I741. Joseph Franqois Dupleix had made himselfDupleix,

shelter. Dupleix, whose whole attention was concentrated on
India, desired to destroy the fortifications of Madras, and to
surrender the place to his friend, the NawAb of the Carnatic.
La Bourdonnais, however, made an agreement with the
English authorities to hold the city to ransom. But his
