Battle of Ambur

French forces were decisive in giving the allies victory; Anwaruddin Muhammed Khan was killed in the battle and Chanda Sahib seized control of the Carnatic.

This decision was confirmed by the Mughal Emperor Ahmad Shah Bahadur but rejected by Nasir Jung, Nizam-ul-Mulk's son, who captured the city of Hyderabad after a coup.

He received the support of the French Governor-General Joseph François Dupleix, who helped release Chanda Sahib the son-in-law of Dost Ali Khan, who was imprisoned after being overrun by the Marathas and after his father-in-law was killed in the fray.

Chanda Sahib sought the investiture of the Mughal Emperor Ahmad Shah Bahadur by declaring himself Nawab of Tinnevelly and gathered his own army of 3500 men and even received 400 French infantry from Dupleix.

Together they marched towards Arcot, the capital of the Carnatic and sought to eliminate Anwaruddin Muhammed Khan, who supported Nasir Jung's claim to the Hyderabadi throne.
