I want to know the answer to the following question:
What was the British Indian Army mostly composed of?
All the background I'm provided with is that "During the middle decades of the 18th century, there were several outbreaks of military conflict on the Indian subcontinent, the Carnatic Wars, as the English East India Company (the Company) and its French counterpart, the Compagnie française des Indes orientales, struggled alongside local rulers to fill the vacuum that had been left by the decline of the Mughal Empire.". Is that enough to answer the question?
