The collection consists primarily of a set of handcolored, topographical, manuscript maps (111 of them), created by Louis-Alexandre Berthier, an officer on General Rochambeau's staff, depicting the historic overland march of the French and American forces from Philipsburg, New York, to Yorktown, Virginia, in 1781 and their return march to Boston, Massachusetts, in 1782. Accompanying these maps is Berthier's journal (in French), providing a detailed description and explanation of the routes covered by the maps. In addition, there are documents and memoranda concerning French military events in America, Berthier's departure from France in 1780, and his return to France via the West Indies in 1782-1783.

Collection Description & Creator Information

Scope and Contents

Berthier's maps, numbering 111, are the most notable feature of the collection. They do not comprise an atlas or a series of separate items, but, rather, they are the consecutive record of that important and historic Revolutionary War military event, the overland march of the French Army under Rochambeau (joined by American forces at Philipsburg) from Newport to Yorktown during the summer and early autumn of 1781, and the return march of the French Army from Virginia to Boston the following year, July - December 1782. These were executed, presumably soon after the event, from information and sketches made on the spot while Berthier was accompanying Rochambeau's Army in America. The maps fall into two interrelated series: the first showing the French Army's camp sites on the southward march from Newport, Rhode Island, to Yorktown, Virginia, in 1781, and on the return march northward in the summer and autumn of 1782; the second showing the "itineraries" or daily marches of the Army (from Newport as far as Elkton, Maryland, in 1781; the daily marches for the 1782 northward journey are lacking among the Princeton papers.) Another set of Berthier's maps is preserved among the Rochambeau Papers in the Library of Congress; this set, although duplicating in part the Princeton set, is apparently less complete

Although Berthier's maps are the most spectacular part of these papers at Princeton, they cannot be fully appreciated without the accompanying textual material of his journal (1780-1783), which provides a detailed description and explanation of the routes covered by the maps. In addition, there are related manuscripts and documents, including a letter (1785) from Rochambeau, notes on the history of Virginia, and Berthier's journal of his later visit to Prussia (1783).

Collection Creator Biography:

Berthier, Louis-Alexandre, 1753-1815

Louis-Alexandre Berthier (1753-1815), one of the four sons of Jean-Baptiste Berthier, was born in Versailles, where his father was in charge of the Royal Map Service. He entered the army as a young man; in 1777, at the age of twenty-four, he attained the rank of captain. In 1780 he asked to be assigned to Rochambeau's army which was preparing to leave for America, and was offered a place on the staff of Count de Saint-Maisme who commanded the Soissonais regiment. Through a series of mishaps and misunderstandings (related in the journal in the Princeton Library), Berthier did not leave with Rochambeau's army when it sailed from Brest in May 1780, but proceeded to America via the West Indies and finally joined up with the army at Newport, Rhode Island, on September 30, 1780.

In January 1781, Captain Berthier was assigned to the staff of General Rochambeau, as "aide maréchal général des logis surnuméraire." In this capacity he accompanied the army in 1781 on its march to Yorktown, and in 1782 on its return march to Boston, and thence to the West Indies, before returning to France. In all, Berthier was in the United States from September 30, 1780, until December 24, 1782.

After his return to France, Berthier was sent on a military mission to Prussia in 1783. (The Journal of this mission is among the manuscripts at Princeton.) He continued to be employed in staff posts, and to earn regular promotions. When the French Revolution came he again saw active service in the field. In 1796 he accompanied General Bonaparte in the Italian campaign, as chief of staff of the army. Henceforth, his fortunes were linked to those of Bonaparte. Berthier participated in the coup d'état of the 18th Brumaire (1799) which established the Consulate, and received the post of Minister of War. Soon after Bonaparte became Emperor Napolean I, in 1804, he chose Berthier as one of the eighteen army officers to be named Marshal of the Empire. Subsequently, Berthier acquired other titles: Duke of Valangin, Price of Neufchâtel, Prince of Wagram. Marshal Berthier was with Napolean in the campaigns of Austerlitz, Jena, and Friedland; he was in the Peninsular Campaign (1808), the Austrian Campaign (1809), in Russia (1812), Germany (1813), and France (1814). In 1814 he abandoned Napoleon, and died the following year, on June 1, 1815, at Bamberg.


These papers are housed in the original red portfolio cases (and order) in which they were presented to the Library in 1939.
