The Institute’s manuscript collection provides primary source documentation of the American Revolution from the points of view of its participants. Official communications transmit military orders and intelligence about the enemy. Personal letters home reveal soldiers’ hopes and fears. Diaries offer details of battles, marches and camp life. Post-war memoirs recount the events with perspective and hindsight.
Muster rolls, clothing and equipment accounts, hospital registers and other records support research on military organization and management. A special strength is a collection of more than fifty American and British orderly books, which document the day-to-day operations of individual units.
The study of the art of war is reflected in cadets’ exercise books, manuscript extracts from published treatises, and original works on the theory and practice of warfare by military officers. The finely executed illustrations of many of these works demonstrate that the art of drawing was considered an essential part of a military education in the eighteenth century.
This watercolor drawing depicting the test-firing of a cannon is part of a volume of plates detailing all aspects of the production and use of artillery. Labeled “Tome 2,” the work is thought to have been intended for publication with a text volume, now lost. The author, baron d’Espiard de Colonge, was field marshal and director of the Guyenne Artillery in France.

“Method for exercise of the light infantry”
William Howe, 5th viscount Howe
1774
The Robert Charles Lawrence Fergusson Collection
In the years following the Seven Years’ War, the British army sought to reform infantry tactics to use elite “light” companies within foot regiments. During the summer of 1774, Maj. Gen. William Howe established an infantry camp at Salisbury to train the selected companies in the new method. Within two years Howe’s reorganized infantry faced its first major challenge, when he became commander in chief of the British forces in America. This manuscript volume bears the ownership inscription of Lt. Gen. George Lane Parker when he was colonel of the Twentieth Regiment of Foot in 1778.

“Notes relatives aux mouvemens de l’armee françoise en Amerique”
François-Ignace Ervoil d’Oryé
Late 18th century
The Robert Charles Lawrence Fergusson Collection
This set of five bound journals kept by a French army engineer with Rochambeau’s forces documents his experiences in America from his arrival at Newport, Rhode Island, in 1780 through his march with the allied armies from New England to Virginia to take part in the siege of Yorktown. It also includes his later travels in Virginia with the marquis de Chastellux and the French army’s march back to Boston. The journals were probably written after his return to France and appear to have been drawn largely from a group of letters (also present) he had written to his family during the war.

“To the President of the United States: The respectful Address of the Officers of the late American Army and Navy assembled in the Society of the Cincinnati of the State of New York”
New York State Society of the Cincinnati
1812
The Robert Charles Lawrence Fergusson Collection
The members of the New York branch of the Society of the Cincinnati addressed President James Madison on the subject of the threat of war with Great Britain in this letter. They were united on several cardinal points: “That our essential rights as a free and independent nation are at every hazard to be maintained. That the constitution of our country, established by the choice of the people, is in every event to be defended from all foreign control or interference. That invasion from abroad, from whatever quarter, is to be repelled by united and vigorous exertions.” They concluded that “making this declaration of our sentiments the same with those which led us to assist in fighting the battles of our revolution, we chearfully dedicate the remnant of our lives to the maintenance of them—and we pledge ourselves to stand ready to seal our sincerity with our blood.”
