Important early plan of Fort Harmar, from Collot's monumental Voyage dans l'Amerique Septentrionale ou Description des Pays Arroses par le Mississippi, l'Ohio, le Missouri, et Autres Riveres Affluentes, published posthumously in 1826, but based upon Collot's work 20-30 years earlier.
Collot's work is one of the highpoints of post-Revolutionary War Americana. The maps, engraved by Tardieu, are among the earliest detailed depictions of the Ohio and Mississippi Rivers along with large maps of the West Anticipating the reacquisition of Louisiana from Spain, France sent Collot to America in 1796 to gather intelligence about the western part of the continent. Because of the Louisiana Purchase, however, the work was printed … but not published at the time of Gen. Collot's death in 1805. More than 20 years afterwards, the whole impression came into the hands of M. Bertrand, … who reserved 100 copies of the English and 300 of the French edition, and made waste paper of the remainder.
Collot's survey was the most precise of the western interior performed up to that time. Ft. Harmar, at the confluence of the Ohio and Muskingum Rivers, was built by Josiah Harmar at the direction of the Conferation Conference in 1784, in order to discourage settlement in the area. Rather than discouraging squatters, the fort encouraged illegal settlement as the migrants believed Harmar's troops would protect them from Native American attacks.
No separate example has appeared in the past 20 years.
Georges Henri Victor Collot (1750-1805) was a French soldier, explorer, colonial official, and spy. He served in France’s possessions in North America and the Caribbean. Born in Chalons-sur-Marne in northeastern France in 1750, the young Georges joined the army. He quickly ascended the ranks.
Collot’s first American experience was as a French officer fighting alongside General George Washington in the Revolutionary War. He served as aide-de-camp and maréchal des logis under French general Rochambeau.
From 1792-4, now a Major General, Collot was Governor of Guadeloupe. His time in the Caribbean was short-lived, however, as the British invaded the French colony, imprisoned Collot, and sent him to New York. He evaded punishment and the French turned his presence to their advantage.
Collot was ordered on a reconnaissance mission on the Ohio and Mississippi Rivers. He was to assess the military capacity and fortifications of their imperial rivals, Spain and Britain, as well as to report on the expansion of the Americans westward.
In the spring of 1796, Collot set out. He navigated southward through Illinois and Upper and Lower Louisiana, drawing detailed maps and plans along the way. His presence was not a secret, however; the English, Americans, and Spanish all issued orders to halt his progress. When Collot arrived in New Orleans in October of 1796, the Spanish Governor, Carondelet, seized Collot and his maps. He was released in early December and returned to France.
Changing imperial politics delayed the publication of Collot’s account of his voyage until 1805. He died in the same year. At the time of his death, his Mississippi journey was little known. It was only in 1826 that a limited reissue of his account was published by Arthus Bertrand. He printed 300 French copies and 100 English; Bertrand destroyed the surviving 1805 examples.
Collot’s maps and plans remain scarce today, but they are superbly rendered cartographic works detailing the contested Mississippi and Ohio River Valleys.
