A collection of 74 letters and documents, 1862-1866, concerning the efforts of the French to establish and maintain an empire in Mexico under the rule of the Austrian Archduke Ferdinand Maximilian (1832-1867). Almost all the letters were sent to General Achille François Bazaine.

The Papers contain manuscripts, lists, and notes of American author and historian Arthur Julian Pilgram (Princeton Class of 1902) for his six-volume work, Military Compendium of Napoleon and His Armies, which covers the Napoleonic and Spanish Wars and the history and organization of the French army.

This collection contains correspondence, reports, and documents of Eugène de Beauharnais relating to European military affairs during the Napoleonic era, which were primarily accumulated by him in his capacity as viceroy of the Napoleonic Kingdom of Italy (1805-1814). Also included are papers documenting Beauharnais' position at the Congress of Vienna (1814-1815), his establishment in the Bavarian duchy of Leuchtenberg (1817), and his later life as Prince d'Eichstätt (1817-1824).

Consists of papers relating to the preparation of The American Campaigns of Rochambeau's Army, 1780-1783 (1972), which was translated and edited by Princeton's Special Collections librarian Howard C. Rice and Anne S. K. Brown.

Consists of over 2,000 autograph items of prominent English and European figures from the 16th to the mid-19th centuries compiled by the English collector John Wild.

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.

This collection consists of an album of 38 photographs (5" x 7" and 9" x 11") taken during World War I and collected by Marion Eppley (Princeton Class of 1906).
