From The Anarchy: The East India Company, Corporate Violence, and the Pillage of an Empire, by William Dalrymple (Bloomsbury, 2019), Kindle pp. 90-91:
Soon both the British and the French were intriguing with the different states in the south, covertly offering to sell their military assistance in return for influence, payments or land grants. In 1749, in return for a small trading port, the EIC became involved in its first attempt at what today would be called regime change, taking sides in a succession dispute in the Maratha kingdom of Tanjore. The attempted coup was a miserable failure.
Dupleix, however, had much more success as a military entrepreneur. His clients had to pay for their European weapons and troops in land grants and land revenue collection rights that would enable the French Compagnie to maintain its sepoys and finance its trade from Indian revenues rather than importing bullion from Europe. Dupleix sold his services as a mercenary first to one of the claimants to the throne of the Carnatic, and then, in a much more ambitious move, despatched the Marquis de Bussy to Hyderabad to take sides in the succession crisis that had followed the death of the region’s most powerful Mughal overlord, Nizam ul-Mulk, as his sons fought for control of the Nizam’s semi-detached fragment of the Mughal Empire. Dupleix was handsomely rewarded for his assistance with a present of £77,500, the high Mughal rank of Mansab of 7,000 horse – the equivalent of a Dukedom in Europe – the rich port of Masulipatnam and a jagir (a landed estate) worth £20,000. Selling the services of his trained and disciplined troops, he soon realised, was an infinitely more profitable business than dealing in cotton textiles.
Dupleix’s generalissimo, the Marquis de Bussy, who also made a fortune, could hardly believe the dramatic results his tiny mercenary force achieved as he marched through the Deccan: ‘Kings have been placed on the throne with my hands,’ he wrote to Dupleix in 1752, ‘sustained by my forces, armies have been put to flight, towns taken by assault by a mere handful of my men, peace treaties concluded by my own mediation … The honour of my nation has been taken to a pinnacle of glory, so that it has been preferred to all the others in Europe, and the interests of the Compagnie taken beyond its hopes and even its desires.’
In reality, however, these were all two-way transactions: weak Indian rulers of fragmented post-Mughal states offered large blocks of territory, or land revenue, to the different European Companies in return for military support. The warfare that followed, which usually involved very small Company armies, was often incoherent and inconclusive, but it confirmed that the Europeans now had a clear and consistent military edge over Indian cavalry, and that small numbers of them were capable of altering the balance of power in the newly fractured political landscape that had followed the fall of the Mughal Empire. The Carnatic Wars that rumbled on over the next decade might have had few conclusive or permanent strategic results, but they witnessed the transformation of the character of the two Companies from trading concerns to increasingly belligerent and militarised entities, part-textile exporters, part-pepper traders, part-revenue-collecting land-holding businesses, and now, most profitably of all, state-of-the-art mercenary outfits.
