East India Company

In 1774, Baldwin returned to Cairo and then back to England, where he learned that the East India Company had successfully begun a trade route between India and Suez. Offering his services to the Company, Baldwin was accepted and returned again to Egypt, where he was the only British merchant. With his knowledge of Arabic he was able to monopolise British trade caravans passing from Suez to the Nile, and ensured a fast, safe and efficient service. At some point between 1776 and 1778 he was reported to have climbed the Great Pyramid at Giza and drunk a mixture of waters from the Nile, Ganges and Thames, symbolically linking the trade routes he managed. By 1779, his trade was so successful that it began to impinge on that of the Ottoman Sultan and of the Cape of Good Hope, prompting protests and restrictions on his activities. In May, one of his caravans was attacked and looted, with some merchants taken hostage. Baldwin exchanged himself for the merchants and later escaped, reaching Izmir.^[1]

An attempt to set up in India ended in failure when Baldwin was assaulted and robbed en route, and he and his wife returned to Britain, pausing in Vienna.^[1]

Return to England

While living in England, Baldwin wrote memoranda for the India Board of merchants, emphasising the importance of influence in Egypt to trade with India and the Middle East and the risk to British interests if France was allowed to dominate Egyptian trade. His advice was not taken up and no resources were deployed to the region until 1786, when a license was issued that allowed French merchants to make use of the Red Sea. In response, Baldwin was sent to negotiate similar licenses for British merchants and observe French activities. While there he deepened his interest in magnetic therapy, holding sessions with an Italian poet to investigate the effects of magnetism on the unconscious. When the French Revolutionary Wars broke out between Britain and France in 1793, Baldwin was able to forward the message to the British government in India, which could then take action against French territories there. In 1796, he investigated unsuccessful French efforts to persuade the Egyptian rulers to allow French armies safe passage through their territory on their way to India.^[1]

Despite his efforts, the British government terminated his post in 1793, although the message did not reach him until 1796. Frustrated, Baldwin left Cairo and thus was not present during the Mediterranean campaign of 1798, when a British force under Sir Horatio Nelson was unable to gain audience with the Egyptian government to warn of the impending attack, as they had no ambassador. When the French invaded Egypt, Baldwin left the country and traveled to Europe before taking up residence in Florence. After the Battle of Marengo, he moved to Naples and from there assisted with the planning of the British counter-invasion of Egypt and travelled with the army as a logistical officer, witnessing the successful campaign and securing local sources of supplies from his contacts in the country.^[1]

In May 1801, Baldwin returned to London and settled there, continuing his studies in magnetic theory, which by this time had been dismissed as pseudoscience. As a result, Baldwin was ridiculed and although he published a number of works on the subject in 1801 and 1802, he did not write again until 1811, when his research was privately printed.
