In 1755, General Edward Braddock famously led a British army to a costly and humiliating defeat about eight miles from the junction of the Ohio and Monongahela Rivers (the site of modern Pittsburgh.) In a passage from his autobiography, Benjamin Franklin offers his one explanation of what happened.
This general was, I think, a brave man, and might probably have made a figure as a good officer in some European war. But he had too much self-confidence, too high an opinion of the validity of regular troops, and too mean a one of both Americans and Indians. George Croghan, our Indian interpreter, join’d him on his march with one hundred of those people, who might have been of great use to his army as guides, scouts, etc., if he had treated them kindly; but he slighted and neglected them, and they gradually left him.
In conversation with him one day, he was giving me some account of his intended progress. “After taking Fort Duquesne,” says he, “I am to proceed to Niagara; and, having taken that, to Frontenac, if the season will allow time; and I suppose it will, for Duquesne can hardly detain me above three or four days; and then I see nothing that can obstruct my march to Niagara.” Having before revolv’d in my mind the long line his army must make in their march by a very narrow road, to be cut for them thro’ the woods and bushes, and also what I had read of a former defeat of fifteen hundred French, who invaded the Iroquois country, I had conceiv’d some doubts and some fears for the event of the campaign. But I ventur’d only to say, “To be sure, sir, if you arrive well before Duquesne, with these fine troops, so well provided with artillery, that place not yet completely fortified, and as we hear with no very strong garrison, can probably make but a short resistance. The only danger I apprehend of obstruction to your march is from ambuscades of Indians, who, by constant practice, are dexterous in laying and executing them; and the
