"The original Map, of which this is a copy, was made in 1798, under direction of General George Henry Victor Collot, an officer in the army of Napoleon.
In that year it was thought that war might break out between the United States and France, and the French Government sent three men, Powers, Collot, and Warren, to visit different sections of the United States in order to see what dissaffection existed among the French people that might be turned to good account to aid France in case of a war.
Detroit was the most important of the French-Canadian settlements. That place had remained in possession of the English until the summer of 1796, and it was naturally supposed that there would be few Americans in the post. Collot did not personally visit Detroit, but went up the Mississippi and ohio Rivers, as far as Cincinnati, and then returned to France after gaining all the information he could regarding the country and its people.
The map is exceedingly accurate if we take into account that the surveys for the map and the soundings were made with such secrecy and stealth, that no official in either the United States or England knew that the plan was being prepared.
The original map was, until lately, hanging in the Department of Marine in the city of paris, and a description of it is given in Parkman's Conspiracy of Pontiac.
