The Schoff Revolutionary War Collection contains the papers of John Adlum, private in the Revolutionary War, Major in the Provisional Army, Brigadier General in the Pennsylvania Militia, surveyor, and viticulturalist. The collection includes 16 items written between 1794 and 1808, and 2 drafts of his memoirs, 1773-1784.
Of the letters, three deal with Adlum's activities surveying the upper Susquehanna River in 1794. The ten items from 1799 relate primarily to his service with the Provisional Army, 11th Regiment. In these letters, Adlum describes his meetings with the Seneca Chief, Cornplanter, who insisted that if the Seneca did not receive annuity payments due them, they would have to resort to hostilities. The 1807 and 1808 items are personal letters from Abel Marple and the undated/unidentified letter discusses relations between whites and Indians.
The memoirs, composed during and shortly after the Revolutionary War, are an account of Adlum's early years and of the period during which he was an active soldier in the war. Writing as a young private taken prisoner at the fall of Fort Washington, he describes British-held New York City from November 1776, until his parole in late 1777. The memoirs also offer glimpses of Nathanael Greene, George Washington, Wilhelm Knyphausen, Ethan Allen, and Hugh Gaine.
