Jacob Jennings Brown papers, 1799-1950s (majority within 1799-1837)

2.25 linear feet

This collection consists of military, political, and family correspondence of Jacob Jennings Brown, an American general during and after the War of 1812.

The Jacob Jennings Brown papers (707 items) consist of military, political, and family correspondence of Jacob Jennings Brown, American general in the War of 1812. Of special note are several pre-war letters written to New York Governor Lewis Morris, concerning land along the Black River in 1806, and about lobbying for the financing of road-building operations in the Brownville area in 1804 and 1805. Also important is the substantial correspondence in 1814, between Brown and his subordinate, Winfield Scott, regarding plans and intelligence reports outlining the Niagara Campaign. Other notable correspondents are DeWitt Clinton, General James Miller, General John A. Dix, and John C. Calhoun. Many post-war letters comment on national and state politics between 1823 and 1827, including letters from New York Senator Ambrose Spencer, and an account of a quarrel between Colonel Joseph L. Smith of Green Bay and General Alexander Macomb of Detroit.

The bulk of the letters and documents from after Brown's death are the 169 letters from his son -in-law Edmund Kirby, who was one of Brown's executors. These letters deal with Kirby's business interests, particularly in the development of Dexter, New York; routine army matters in regard to his role as paymaster of the army; and letters concerning the settlement of Brown's estate. Fifty-five additional documents and business papers from 1830 to 1851 cover the same topics.

They describe the toll that railroad traffic took on Bellows Falls Canal use. The first and second books, (October 10, 1836-September 17, 1840 and November 3, 1840-February 27, 1847, respectively) have alphabetical indexes of names mentioned in the books, while the third volume (March 12, 1847-September 15, 1849) has no index and is only ¼ full. The diary pages are extremely fragile and the texts are typically impressions from carbon paper copying except for the page numbers, which are in ink or pencil. The second and third volumes were kept by a J.L. Stackpole.

The Documents and Deeds series consists of various contracts, bills, inheritance documents, and land transfers. Included in this series are thirteen oversized items, all of which document the sale of land. Atkinson purchased land along the Delaware River in New York State; in Middle Island Creek in Ohio County, Virginia; in Ulysses, Pennsylvania; along the Cacapon River in Hampshire County, Western Virginia; and in Columbia Territory, Maryland. He sold land in Ontario, New York, and Bellows Falls, Vermont, to his son-in-law Alexander Fleming.

The John Peddie collection includes a signed letter from John Peddie to William Henry Clinton, written from a bivouac on the "banks of the Bayoue Catalan" and dated January 24, 1815. Peddie wrote of "the fate of our unfortunate Expedition," referring to operations surrounding the Battle of Lake Borgne and the Battle of New Orleans. He offered his opinions about the causes of the British failures. Peddie requested Clinton's aid in securing a promotion.

Peddie enclosed a manuscript map of "Genl Lambert's position on the River Mississip[p]i," signed by John Fox Burgoyne, and a 15-page copy of Charles Ramus Forrest's "Journal of the Movements of the Army acting in the Southern part of the North American Coast." Forrest's account describes events from November 25, 1814, through January 7, 1815. He remarked on Major General Keane's command in Negril, Jamaica, the movements of the British Fleet as they proceeded to the American coast, and subsequent military decisions, maneuvers, and engagements leading up to the Battle of New Orleans. Forrest provided details on difficulties faced by British troops, including unfavorable tides and geography, and described military encounters with American forces. He also noted work on the Villeré Canal and included copies of orders and memoranda concerning military preparation and actions. Forrest concluded by summarizing the circumstances that stymied the British efforts in New Orleans, including their distance from supplies; the "impossibility of gaining intelligence" from locals, prisoners, and African Americans; the bad "nature of the Soil"; Americans' ability to prepare in advance and establish a strong line of defense; and the unexpected local opposition to the British.

The letter and enclosures are part of the larger Henry Clinton papers, though they are housed separately.

Collection

John Peterkin journal, 1817-1819, 1837-1838

1 volume

The John Peterkin journal includes letters written by Peterkin, a Scottish immigrant to Virginia and Georgia in 1817-1819, to family and friends in Scotland and Pennsylvania, as well as writings by William Russell, a later owner of the journal. Peterkin wrote about his thoughts on slavery, the displacement of Native Americans, and democracy.

The John Peterkin journal contains approximately 200 pages of entries, including letters written by Peterkin to family and friends in Scotland and Pennsylvania, lists, copies of letters, and writings by William Russell, a later owner of the journal, which are scattered throughout.

The majority of the journal resembles a letterbook and contains correspondence that Peterkin wrote to his family and his sweetheart, Harriet, between 1817 and 1819. In his letters, he described his journey from Scotland, including smuggling a companion onboard the ship (August 14, 1817); his first impressions of the United States; his negative feelings toward slavery and the displacement of Native Americans; and his ideas about democracy and the War of 1812.

On July 5, 1818, he wrote a letter to Harriet describing a visit to Powhatan, Virginia, and for several pages discussed the story of Pocahontas and the treatment of the Powhatan by settlers, which he found reprehensible. He also opined that whites "have no right to this country." In an additional letter of the same date, written to James Ross in Scotland, Peterkin described the brutality of slavery, particularly in the Deep South. He further explored this topic in his last letter in the book, dated August 4, 1819, in which he called Georgia "semibarborous" and stated, "I read in the declaration of the independence of this Country that all men are born free and equal, but I cannot look out door or window that I do not see the directest lie given to the assertion… it certainly appears to any reflecting mind a strange view of contradiction, and were it not that it involves consequences of so tragick a nature, it would be truly laughable." Peterkin also discussed signs of western expansion (July 5, 1818), the aftermath of the War of 1812 (March 27, 1818), and compared his experiences in Virginia and Georgia (March 25, 1819).

The journal also includes writings during the 1830s by a later owner, William Russell, of Augusta, Georgia, who wrote poems, lists, and a few letters in the volume. Several of his poems concern the beauty of nature and his longing to return to Scotland, and his writings describe his travels in New York City (January 24, 1838) and Philadelphia (January 25, 1838). His entries are scattered throughout the volume, but the two hands are easily distinguishable.

The John Rodgers papers contain Rodger's professional correspondence and documents from shortly before his first Naval Commission through the end of his career. The collection holds 719 letters, 39 legal documents, 1 letterbook, and 2 genealogical items. These provide a wealth of information on nearly every aspect of Rodgers' career, from his blockading and diplomatic activities during the Barbary Wars through his brief tenure as Secretary of the Navy. In addition to documenting Rodger's career, the papers are also a source of information on the administration and political workings of the United States Navy in the early 19th century.

The Correspondence series (719 items) contains letters about Rodger's naval career, including his role in the Barbary War, his part in the War of 1812, his return to the Mediterranean after the war, and his tenure as administrator of the Navy Commissioner's Office.

The Barbary War materials contain important information on the activities of the United States' fleet off Tripoli and on the attitudes of the United States officers toward the Barbary States. These include intelligence documents used during naval operations and Barbary treaty negotiations. Many of the items are from the Navy Department, including letters from the highest rank of naval officers in Washington and the officers stationed at the Philadelphia and New York navy yards. Of note are:

  • Several navy circulars from 1808, which discuss the embargo laws
  • A letter from New York Congressman, Killian Van Rensselaer (1763-1845) about a deserter from the John Adams (July 1808)
  • A 60-page diatribe from Rodgers addressed to William Eaton, the acting Navy agent for the Barbary Regencies, which berated Eaton for impugning Rodger's name in a report to the secretary of the navy on the negotiations with Tripoli (1806). This document includes copies of letters from Samuel Barron (May 18, 1805), and Tobias Lear (May 19, 1805), used to support Rodger's viewpoint.

Letters from the War of 1812 period concern Rodgers' command of the naval forces in the northern Atlantic, which attempted to blockade the British shipping efforts in North America. The collection contains a few important accounts of engagements with British warships; approximately 30 reports of ships boarded by United States gunboats in the Atlantic; and intelligence on British naval activity around New York, Washington, and Baltimore. Of particular interest is a letter from a low-ranking navy member named Amos Brown, who was impressed by the British in Halifax, and wrote to Rodgers to request clearance to return to New York (June 9, 1812). Brown had served with Rodgers, but described his physical appearance to help jog Rodgers memory, in the hopes of obtaining his freedom. Also of note are a report from Paul Hamilton on the consequences of the Little Belt Affair (May 23, 1811), and a letter from his brother George Washington Rodgers, who wrote of family and navy matters (February 23, 1814).

The post-War of 1812 portion of the collection provides documentation for the peace-time operations of the United States Navy, including: ship building, harbor maintenance, regulations, and military discipline. From 1815-1824, Rodgers was the president of the Navy Commission in Washington D.C. He received frequent letters, marked "private," from Howes Goldsborough (1816-1824), and in 1823 received several letters from New York Congress Member Cadwallader David Colden.

Rodgers was stationed in the Mediterranean from 1824-1826, and served on the Navy Board of Commissioners from 1827-1837. Most of the letters from these years are administrative in natures. Of note are:

  • Nine letters from Rodgers to the fleet captain of his Mediterranean Squadron, Daniel Todd Patterson, of the USS North Carolina and the USS Brandywine (1825-1826). These include instructions on protocol, qualifications for officers, and general orders for ship maneuvering.
  • A 16-page report from the Navy Commissioners on the restructuring of the navy (November 23, 1829).
  • A private letter from Matthew Calbraith Perry with news of his son and the mission in the Mediterranean (February 11, 1831).
  • Eight letters from Rodgers addressed to James Barron, commander of the Philadelphia Navy Yard.

Though the collection is largely made up of official naval materials, it also contains content related to Rodgers’ family life. Frederick Rodgers, who was also in the navy, wrote two letters to his father (March 9 and April 5, 1828). Rodgers received a letter dated April 6, 1828, from one of the crew of the USS North Carolina, informing him that Frederick had died while heroically trying to save one of his shipmates after their boat sunk. Minerva Rodgers' sister Eliza wrote to her on August 17, 1828, to console her on the loss of her son).

The bulk of John Rodgers' family letters, written after his death, are dated between 1840 and 1908. These include letters between Minerva and her sons John and Henry, as well as an item to eldest son Robert Smith Rodgers, a civil engineer, and a few unsigned items. An unsigned letter from March 14, 1877, relates tensions between the North and South and news about the Hayes administration. Another item of interest is a January 9, 1872, incomplete and unsigned letter from Wusong, China, addressed to "Brother," likely from Rodger's grandson, John Rodgers, who served in the navy until his death in 1882. The writer described his time in Japan and commented on Japanese cultural practices. He wrote of his experiences in a bath house:

"the people of Japan are kind and amiable, but they are strangely careless of modesty -- they have no idea of it. Girls said to be proper and good girls and very pretty ones, came into the room where I was Bathing and wanted to scrub my shoulders with soap -- As I had no bathing dress on, you can guess how much I was horrified."

He mentioned his audience with the Mikado, and also provided information about the landscape and architecture. He admired their paper screens, which "have some advantages over our windows."

The collection also contains several letters from Rodgers’ grandson, Colonel Robert S. Rodgers, to friends, family, and colleagues.

The Letterbook series is a single volume, containing five letters by Rodgers while aboard the U.S.S. North Carolina in 1825. Three of the letters are addressed to Secretary of the Navy Samuel L. Southard and concern a court martial, various matters relating to the ship's crew, and his support for promotions. Another letter is addressed to Charles Morris and briefly mentions the ship's crew and their imminent departure to the Mediterranean. The final letter, addressed to Howard March & Co. from Gibraltar, concerns an order of Madeira wine.

The Documents series (39 items) consists of general orders, circulars, courts martial opinions, reports, and lists of ships stores. The earliest item is a list of 44 guidelines, written by Rodgers, to be followed on board the U.S. Maryland, including instructions for exercising cannons (August 29, 1799). The series contains a number of materials related to sickness, dating from 1825-1828, including doctor's letters excusing service members from their posts, as well as reports relating to illnesses onboard navy vessels. Of particular interest is a report on the causes of yellow fever on board the frigate Macedonian, which the two investigators attribute to sudden changes in climate during the voyage, poor diet and clothes, the "offensive state of the hold," and an error in treatment methods by the ship's doctor (August 23, 1823). Other notable material includes:

  • A court of inquiry document concerning the Chesapeake-Leopard Affair (1807).
  • A formal petition to Secretary of State James Monroe from 15 prisoners of war in the Melville Prison in Halifax requesting relief, (August 30, 1812).
  • An article of agreement with Charles Washington Goldsborough in a Washington-based lumber and brick-making business (October 30, 1815).
  • 30 reports documenting vessels boarded by US Naval squadrons and gunboats while enforcing the Embargo Act of 1807. These records contain the date of the boarding, the name of the vessel, the ships’ master and owner, its origin and destination, the cargo, and additional remarks.

The Genealogy series (3 items) contains two pages (followed by 11 blank pages) of notes, written by Rodgers, relating to his early life at school and as a young sailor. The series also holds a four-page document from the Sons of the American Revolution tracing Rodgers' family lineage to Captain George Denison's and a five-page photocopy of genealogical information on Rodger's family. Both items are undated.
