The most significant incident in this war, however, took place a month later. The Mughal Nawab of the Carnatic, Anwar ud-Din, was furious with Dupleix for ignoring his orders by attacking Madras without his permission, and then insulting him by refusing to hand over the captured town to his authority. He had no intention of allowing a trading company to defy his rule in this manner, so he sent his son, Mahfuz Khan, with the entire Mughal army of the Carnatic, to punish the French.
