Collot's map of Pittsburg is one of the earliest plans of the city (as opposed to merely Fort Duquesne or Fort Pitt) .
The map shows the confluence of the Ohio, Allegheny and Monogahela Rivers, the small forts build by General Wayne, the Ruins of Fort Pitt, Fort Lafayette, a town plan, Stone Quary, the Road to Philadelphia, Coal Mines on the south side of the Monogahela, and a number of other roads and smaller fortifications. The key includes further notes on Fort Lafayette and the 3 rivers.
Rumsey notes that the map pre-dates the Louisiana purchase in 1803.
French General Victor Collot's survey in 1796 was part of an intelligence mission into Spanish Louisiana and Florida in preparation for a possible French attack on the Spanish colonies. Collot was arrested by Governor Carondelet and expelled from the colony. Although Collot traveled through the Ohio and Mississippi River valleys in 1796, his two-volume account was not published until 1826. During his inspection tour, Collot observed the topography, resources, and people of these American and Spanish-held lands, which he illustrated with regional maps, town plans, and views in an accompanying atlas. The work was completed in 1804, but delayed 20 years by the death of Collot. The work represented a significant step forward in the mapping of the regions explored. This is one of 23 maps which appeared in the Atlas volume, of which only 100 were printed in English. The work is of extreme rarity and very important in the history of American Cartography
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.
