The Frenchman’s map of Williamsburg, Virginia served as a significant source for the restoration of Colonial Williamsburg. It indicated potential archaeological sites and served as a base for Dr. William Archer Rutherfoord Goodwin’s survey in 1927. The final draft of the map seems to be lost forever but a fine copy (see fig. 1) measuring 55 cm. x 68 cm. is housed in the Special Collections Research Center of the Swem Library at the College of William & Mary.[1] There is no indication as to who the cartographer might have been.

The map is unsigned but the legend in the lower left is written in French. Hence, it has been called “the Frenchman’s Map.” It is dated May 11, 1782. So what brought the French to Williamsburg? And what occurred at that time that necessitated such a detailed map?

Lt. Gen. Jean Baptiste Donatien de Vimeur Comte de Rochambeau came to America with an army of about 6,100 men on July 11, 1780. He and Gen. George Washington learned that British troops withdrew to Yorktown in August 1781, and that Admiral François Joseph Paul Comte de Grasse would sail no farther north than the Chesapeake Bay. De Grasse planned to return to the West Indies by mid-October to avoid being caught in possible hurricanes. So Washington and Rochambeau decided to march south.

Washington’s army arrived at Williamsburg, the rendezvous point, and camped on September 23, 1781. The French troops arrived and camped on the 26th. The allied army composed of 5,000 Americans of the Continental Army, 1,200 Virginia militiamen and 8,000 French then marched for the siege of York at dawn on the 28th.

The Map’s Purpose

After the British surrendered at Yorktown, the French army returned to Williamsburg where they remained until July 1, 1782. One assumption about the Frenchman’s Map is that it was made for the billeting of French troops during the winter following the surrender of Yorktown. That is not likely. The map is dated May 11, 1782. Plans for billeting the troops would have been made in the autumn, before the cold weather, not in May, two months before their departure and when the weather becomes warm.[2] The map must have been created for another reason. Maybe it was meant as a souvenir of Rochambeau’s sojourn in Williamsburg. We may never know.

The Cartographer

As for the cartographer, mapmaking was one of the tasks of the corps of enginneers which included Col. Jean Nicolas Desandrouins, Rochambeau’s chief of artillery. He, however, did not participate in the Yorktown campaign due to illness and his papers were lost at sea in a shipwreck. Chevalier Thomas Antoine de Mauduit du Plessis, captain of artillery and regimental adjutant of artillery, does not seem to have left any papers, nor did Charles Joseph Antoine Soalhat (or Soualhat) de Fontalard, Baron de Turpin or any of the other artillerists.[3] None of the two hundred French volunteers who were commissioned by Congress as engineers in the Continental Army would have drawn the map, as they all marched north with the army in 1781.[4]

Most of Rochambeau’s aides-de-camp were graduates of L’École du Génie (School of Engineering) at Mézières. One of these aides was Louis Alexandre Berthier, who was also Rochambeau’s cartographer. Many of his maps are included in The American Campaigns of Rochambeau’s Army 1780, 1781, 1782, 1783 along with his diary.[5] Pierre-François de Béville was Rochambeau’s maréchal général de logis (quartermaster general) and maréchal de camp (camp marshal), but we have no extant documents of him. Of all his assistants, only three kept journals: Louis Alexandre Berthier, Mathieu Dumas and Louis François Bertrand Dupont d’Aubevoye, comte de Lauberdière.[6]

Quartermasters in the eighteenth century did not only administer food, clothing and equipment. They also took care of laying out a camp, planning routes of travel and making sure roads were in good condition. On the march to Yorktown, each regiment had an assistant quartermaster. Donatien-Marie-Joseph de Vimeur, vicomte de Rochambeau accompanied the Bourbonnais regiment; Alexandre-Théodore-Victor, comte de Lameth marched with the Royal Royal Deux Ponts regiment; Georges Henri Victor Collot went with the Soissonnais regiment; Louis Alexandre Berthier assisted the Saintonge regiment; Mathieu Dumas travelled with Lauzun’s Legion; Hans Axel, comte de Fersen attended the Royal Deux Ponts dragoons while Jacques Anne Joseph le Prestre, comte de Vauban went with the Chartres dragoons and Louis François Bertrand Dupont d’Aubevoye, comte de Lauberdière supported the Royal Normandie cavalerie.

We know that Louis Alexandre Berthier mapped the camps and the route of march. His map of camp number 39 at Williamsburg (see fig. 2) shows where the troops camped on September 26 and 27, 1781. It is very different from the Frenchman’s map (fig. 1) which was drawn eight months later.

Louis François Bertrand Dupont d’Aubevoye, comte de Lauberdière, besides being one of Rochambeau’s aides and quartermasters, was also the general’s nephew. His Journal de l’armée aux ordres de Monsieur le Comte de Rochambeau pendant les Campagnes de 1780, 1781, 1782, 1783, dans l’amérique septentrionale includes several maps of the route of march.[7] While it does not include a map of Williamsburg, it does include one of Yorktown and Gloucester (see fig. 3). Comparing the features of this map with those of the Frenchman’s map reveals many similarities in style, particularly the buildings and river banks. These similarities suggest that the Count de Lauberdière may have been the cartographer of the Frenchman’s map. The script in the map’s legend does not match the script in Lauberdière’s diary, but the person who wrote the legend was probably not the one who drew the map. Historian Michael Lombardi notes that there is evidence of three different people who wrote on the Frenchman’s map.[8]

While the Count de Lauberdière may have been the cartographer of the Frenchman’s map, the true identity of the author and the purpose of the map may may never be known. We hope that this article lends some important detail to this discussion.

[2] The British Parliament voted that there be no further offensive operations in Norh America in February of 1782. This would not have been known in America until April at the earliest. Such an action by the Parliament may have been the sign Washington was looking for before determining the disposition of Rochambeau’s army.
