This collection is made up of 3 letters that Lieutenant Peter Pelham received from a woman in Portsmouth, New Hampshire, while serving in the United States Army during the War of 1812. Pelham's correspondent expressed her anger and feelings of abandonment; her distress upon hearing of poor conditions at Burlington, Vermont; and her daily activities.

This collection is made up of 3 letters that Lieutenant Peter Pelham received from "M. B. S.," a woman in Portsmouth, New Hampshire, while he served in the United States Army during the War of 1812. The first letter ([November 6, 1812]) concerns the author's emotional distress after Pelham's departure for the army; she wrote at length about the perceived injustice and his broken promise. In her second letter (December 26, 1812), M. B. S. expressed her great alarm after hearing of unsanitary conditions at Burlington, Vermont, where Pelham was stationed at the time. She urged Pelham to send her a detailed report about the number of casualties and the state of affairs, offering to circulate his letter should it contain good news. The third letter (May 7, 1814) reflects on Pelham's most recent visit; though she initially remained in bed, distraught, she later socialized with her mother and other acquaintances.

The donor has collected, arranged, transcribed, and annotated each document and has written a well-researched collection description.

The Richard Rush papers contain the incoming and outgoing correspondence of Richard Rush, on topics such as the War of 1812, family news, and political views.

The Richard Rush papers consist of 31 letters, spanning 1812-1856. Rush wrote 19 of the letters; his wife Catherine wrote 4; his brothers, Samuel and William, also wrote a total of 4, and miscellaneous writers contributed a few additional items.

Most of the correspondence in the collection is political in nature. Several letters from the War of 1812 period refer to battles, pirates, and the burning of Washington. On September 7, 1813, Rush wrote to John Binns, agreeing that it had been an error to attack York instead of Kingston and also to leave "the fate of Sacketts harbour [sic] suspended by a hair." In another letter, he stated that he did not believe that the United States should treat light cruisers from "Carthegena" (Cartagena) as pirates (December 26, 1814). A series of four letters written to Rush from his wife, Catherine, gives updates and family news from Piney Grove, Virginia, where she and the children resided in the summer of 1814, in order to avoid the dangers of Washington, D.C. The correspondence mentions the burning of "poor Washington," and reports rumors of the looting of Georgetown (September 3, 1814).

Letters from the post-war period include one from Rush to his partner in the Rush-Bagot Agreement, Charles Bagot, lending him books of speeches by Richard Brinsley Sheridan (January 22, 1817); one to Nicholas Biddle concerning problems with Alabama banknotes (January 21, 1829); and a letter of May 16, 1853, in which he called Harriet Beecher Stowe "the authoress of that systematic and carefully-wrought 'log-cabin' libel against the South," and fretted that she would influence English nobles and possibly "feed a war." Also present are letters from William and Samuel Rush, younger brothers of Richard, to their mother, Julia. These contain family news, references to Richard, and political opinions. In his letters of July 7 and July 27, 1831, Samuel Rush expressed his wish that Richard would support Henry Clay, and wondered in the latter if Richard had been turned against Clay by antimasonry.

The latest items in the collection are a series of eight letters between Rush and Major John S. Williams, who wrote a book on the invasion of Washington by the British. They document Rush's suggestions and corrections to Williams' work, as well as Williams' presentation of the book to George B. McClellan in 1864.

The collection concludes with a farewell letter and religious diatribe from the dying 86-year-old Moses Lyman, a prominent citizen of Goshen, Connecticut.

The Account Book series consists of a 23-page booklet of "Copies of Notes and other Obligations due to me with their Indorsments" (1795-1814). These notes record large transactions (most between $70 and $1,000 with one as high as $4,716.96), and provide details on reasons for the deals and the parties involved.

The Photographs and Newspaper Clippings series holds one of each item. The clipping is undated and likely from a local Cleveland newspaper. The clipped article is "Colonel Samuel Huntington Surveys his Property" by S.J. Kelly, about Huntington's early property holding in Cleveland. The photograph is unlabeled but is possibly a painted portrait of Huntington.

This collection holds the official correspondence of Seth Drew, a Massachusetts native was the superintendent of fortifications for the Army Corps of Engineers between 1808 and 1812. He managed the construction and fortification of the harbor in Plymouth, Massachusetts, in anticipation of war with Great Britain.

The Seth Drew papers (23 items) hold the official correspondence of Seth Drew, the superintendent of fortifications for the Army Corps of Engineers between 1808 and 1812. These letters contain detailed instructions from Joseph Gardner Swift, major of engineers, on the construction and workings of the fort at Plymouth. They also include a rough architectural sketch of a barrack. Jacob Eustis, agent at Boston, wrote about supplying Plymouth with cannon and military stores. Other letters are from Army administrators, particularly from the Accountants Office of the Department of War; these letter-writers include William Eustis, Peter Hagner, William Simmons, and Henry Whiting. In one letter, Henry Whiting described the course of events during the first year of the War of 1812, and commented on the "destitute and miserable conditions" of soldiers returning from prisons in Canada.

The Sylvester Day collection (1813-1920) is made up of 17 letters and documents written by or related to Sylvester Day, a surgeon for the United States military during the War of 1812.

The Sylvester Day collection (1813-1920) is made up of 17 letters and documents written by or related to Sylvester Day, a surgeon for the United States military during the War of 1812, respecting Day's work, his son's education, and additional topics.

Day wrote to his son, Hannibal, praising his academic successes and urging him to continue working hard. Day wrote, "it affords me much pleasure to hear from you, and learn that you are assiduous in the prosecution of your studies … I have no doubt of your being qualified to enter college by next commencement" (October 17, 1817). In a second letter to Hannibal, Day wrote, "It affords me much satisfaction to hear of your good conduct and progress in your studies. I wish you to perfect yourself in the rudiments of arithmetic" (March 27, 1818).

Items pertaining to Day's claims against the United States for reparations reveal the surgeon's professional work ethic. The testimony of David Beard, a purveyor and resident of Detroit, provides insight into Day's dedication to his patients. Beard recalled that Day volunteered to stay in Detroit, even after its surrender to British troops, in order to "attend upon the sick and wounded American prisoners who were unable to be removed. These services were specially important at that time, as no other medical man of either army remained there" (January 6, 1835). The official memorial of Sylvester Day contains an account of Day's departure after the surrender of Detroit and his subsequent detainment and loss of property at the hands of his own countrymen. Day's attorney claimed, "the petitioner ordered on shore, but forbidden to take his baggage & effects which remained in the vessel, and was destroyed when she was burnt by order of Col. Schuyler" (undated).

Three manuscripts from the United States War Department outline milestone dates of Day's military career, along with the locations of specific postings and different positions he held over his lifetime. Also of note is an illustrated, partially printed document certifying Day's contribution of five dollars towards the building of the Washington Monument. This contribution entitled Day to "all the privileges of Membership in the Washington National Monument Society," and bears printed signatures of Zachary Taylor, Elisha Whittlesey, and George Watterston (July 12, 1850). The collection also contains a dinner invitation from Michigan's Governor Lewis Cass, as well as a request for medical aid or referral from General Alexander Macomb in regard to his wife.

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.

The Tobias Lear papers (140 items) are comprised of 118 letters, one diary, and two engravings. The letters are almost all written by Lear, and relate primarily to his career as the United States Consul General to Tunis and Algiers, and to his contribution to the War of 1812, both as a prisoner negotiator with the British and as a war department secretary.
