The Thomas S. Jesup collection (46 items) contains the official correspondence of Jesup, who was a major during the War of 1812 and later quartermaster general of the United States Army. The early letters relate to his career as adjunct to General William Hull at Detroit. These six items document Jesup's parole and exchange after being taken prisoner in the War of 1812. They include communications with British Major General Isaac Brock (1769-1813); John Mason (1766-1849), the American company general of prisoners; Thomas Barclay (1753-1830), agent of the British government; Lewis Cass (1782-1866), Brigadier General of the American Army; and Major General Andrew Jackson (1867-1845).
The remainder of the items relate to Jesup's work as quartermaster general and military leader. The collection holds two notable post-war letters from the period when Jesup was stationed in New Orleans. These are addressed to Secretary of State James Monroe, and concern hostile Spanish maneuverings in the West Indies in the summer and fall of 1816. Jesup also received an invitation to William Henry Harrison's inauguration ball (March 4, 1841), and a letter from Lewis Cass (February 20, 1850). A printed general order dated May 1, 1817, documents Jesup's promotion from major of the 1st Infantry to lieutenant colonel of the 3rd Infantry. Another important item written by Jesup is his March 11, 1822, letter to William McRee, in which he described his reorganization of the military in Washington. Other notable letters include a William H. Winder letter of May 16, 1849, which concerns the 1814 Battle of Bladensburg; and an undated six-page letter written by Jesup giving a firsthand account of the capture of the Seminole Indian chief Osceola (1804-1838), who was captured on October 21, 1837, on Jesup's order when he arrived at Fort Payton for truce negotiations.
Documents in this collection include a receipt of shares for the Chesapeake and Ohio Canal Company, bought by Jesup (1830 and 1832), and two documents that are dated after Thomas Jesup's death. One is Jesup's daughter Jane Jesup Nicholson's 1881 passport, which includes a physical description of her. The other item is a 1917 check in payment to Julia Clark Jesup, another of Jesup's daughters.
