of personal effects to the requisition of weapons or supplies. Cox had taken on the most prestigious infantry regiment, and the 63rd Regiment and the Royal Artillery soon followed. In 1765 Cox went into partnership with Henry Drummond, whose family ran the London bank. Cox & Drummond moved from Cox's house in Albemarle Street to Craig's Court, just off what is now Whitehall. By the mid-1760s Cox & Drummond had blossomed to become agents for the Dragoons and eight more Infantry regiments. Success was built on the company's reputation for keen attention to the welfare of its regiments. In 1763, for instance, when Robert Clive stormed the fortress of Gheria in India, Cox successfully negotiated with the East India Company who had "borrowed" stores from Cox's clients, the Royal Artillery. He arranged to receive repayment from the East India Company by way of plunder from Gheria. He had this converted into silver in India and shipped back to London where the funds were returned to the Royal Artillery. Back home, Cox's house on Albemarle Street (opposite the present-day Ritz Hotel) was known for its parties. In addition, he was a patron of the arts, being acquainted with David Garrick and other notable actors of the time, and was a founding financial investor in the rebuilding of the Theatre Royal in Drury Lane. He was also a generous benefactor to St George's Hospital on Hyde Park Corner (now the Lanesborough Hotel). The records of the family estate at Quarley show that Cox spent over £3,000 per annum running it, much of it lavished on his wife. By 1768, Cox & Drummond were flourishing, with a turnover of £345,000 per annum. During the 1770s the company continued to grow, aided by war in the American Colonies and the threat of invasion from France. Cox repeated his good fortune with business partners, taking in Mr Mair upon Drummond's death in 1772, followed by his own son Richard Bethell Cox in 1779 and then Mr Greenwood in 1783. It was during this time that the company expanded its banking interests, offering loans and accounts to exclusive members of London's elite. Frederick, Duke of York, introduced Cox's business partner Greenwood to his father George III, as "Mr Greenwood, the gentlemen who keep my money". Greenwood replied rather cheekily that, "I think it is rather his Royal Highness who keeps my money", to which George III
