distress among Maryland and Virginia planters, who by the time of the outbreak of war had accumulated debts of around £1 million, a huge sum at the time (equivalent to £ in ). These debts, as much as the taxation imposed by Westminster, were among the colonists' most bitter grievances. It was this extension of cheap credit that made the Glasgow men different. The English merchants simply sold American tobacco in Europe and took a commission. The Scots bought the crop at pre-arranged prices, and made large (and potentially risky) loans to their customers. Prior to 1740, Glasgow merchants were responsible for the import of less than 10% of America's tobacco crop, but by the 1750s Glasgow handled more of the trade than the rest of Britain's ports combined. Heavily capitalised, and taking great personal risks, these men made immense fortunes from the "Clockwork Operation" of fast ships coupled with ruthless dealmaking and the manipulation of credit. Maryland and Virginia planters were offered easy credit by the Glaswegian merchants, enabling them to buy European consumer goods and other luxuries before harvest time gave them the ready cash to do so. But when the time came to sell the crop, the indebted growers found themselves forced by the traders to accept low prices for their harvest in order to stave off bankruptcy. At his Mount Vernon plantation, future President of the United States George Washington saw his liabilities swell to nearly £2,000 by the late 1760s (equivalent to £ in ). Thomas Jefferson, on the verge of losing his own farm, accused British merchants of unfairly depressing tobacco prices and forcing Virginia farmers to take on unsustainable debt loads. In 1786, he remarked:A powerful engine for this [mercantile profiteering] was the giving of good prices and credit to the planter till they got him more immersed in debt than he could pay without selling lands or slaves. They then reduced the prices given for his tobacco so that…they never permitted him to clear off his debt. After the war, few of the enormous debts owed by the colonists would ever be repaid. Despite these setbacks, after the American War of Independence (1775–1783) the Glasgow merchants switched their attention to other profitable parts of the triangular trade, particularly cotton in the British West Indies.
