In conversation with him one day he was giving me some account of his intended progress. "After taking Fort Duquesne,"[20] says he, "I am to proceed to Niagara; and, having taken that, to Frontenac,[21] 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 revolved in my mind the long line his army must make in their march by a very narrow road, to be cut for them through 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 conceived some doubts and some fears for the event of the campaign. But I ventured 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 practise, are dextrous in laying and executing them; and the slender line, near four miles long, which your army must make, may expose it to be attacked by surprize in its flanks, and to be cut like a thread into several pieces, which, from their distance, can not come up in time to support each other."

The name was changed to Kingston by Loyalists who settled at the fort after the American Revolution.]
