The Jonathan Chase papers (73 items) in the Schoff Revolutionary War Collection contain 39 letters, 1 letterbook, and 33 documents and financial records (including receipts, soldier rolls, and commissions) relating to the services of Colonel Jonathan Chase, of the 13th and 15th New Hampshire Militia regiments, during the Revolutionary War. Chase was actively involved in recruiting soldiers and in providing supplies for the army during the war. This collection documents his part in these efforts and includes several wartime letters that depict the military situation in New England.
The Correspondence series contains 39 items, all of which are related to the Revolutionary War. Frequent correspondents include Benjamin Giles, a New Hampshire officer stationed in Charlestown, Massachusetts; Meshech Weare, President of New Hampshire; Major Jonathan Child; Major General Nathaniel Fulsom; and Jacob Bayley. The earliest letters are requests from officers at Charlestown, Massachusetts, with orders for Chase to send flour and meat to feed their troops. Meshech Weare wrote 10 letters on behalf of the Committee of Safety for New Hampshire, headquartered in Exeter. These dealt with military matters, informing Chase of the structure of the militia (July 18, 1777) and calling for him to draft a certain number of men from his militia units to fill a quota mandated by the Continental Congress. Weare specifically recommended that Chase must not trust prisoners of war or enemy deserters (March 9, 1778).
Other notable items include letters dealing with military matters such as deserters (July 23, 1779 and May 27, 1781), and pay incentives for enlisted soldiers (June 20, 1779). A report issued by the New Hampshire House of Representatives, dated April 15, 1781, outlined plans for the defense of the western New Hampshire frontier. One of several letters from Jacob Bayley warned of a possible attack near Otter Creek in Vermont and advised that "each man would equip himself with snow-shoes &c" (February 8, 1780). In an urgent letter, General Peter Olcott advised Chase to have his men ready "to march at a minutes warning to the relief of any quarter which may be invaded" (October 15, 1781). Post-war items, in both the Correspondence and Documents and Financial Records series concern reimbursements from the United States government for expenses incurred during the war. Though most of the items in the collection are official in nature, one letter reveals personal struggles during the war: Elisha Payne, in a letter dated May 12, 1777, explained to Jonathan Chase that he cannot stay with the militia because he must tend to his wife and many small children, and can find no one to take care of his land while he is away; also, he is unsure his health can take the strain.
The 14-page Letterbook contains 34 numbered letters. While the letterbook is largely comprised of copies of records dealing with supplies, food, and money, it also contains letters from Chase, Moses Hazen, Major Jonathan Childs, Jacob Bailey, and Horatio Gates. These describe troop missions and news about the war. Of note are two letters: one is from Moses Hazen mentioning that the French fleet is to be expected to arrive at the end of June, 1780 (p. 9, June , 1780); and the other is 1778 letter to the Chairman of the Committee of Bennington discussing the sending the 15th New Hampshire regiment to defend Vermont (p.12-13, ).
The Documents and Financial Records series (33 items) contains lists of officers and soldiers recruited and dispatched by Chase, records of military expenses kept by Chase, and 3 printed items appointing Chase to various official positions. Nine items are regimental returns and other lists of soldiers, including returns for soldiers who marched with Chase to Ticonderoga and Saratoga. One document, of June 10, 1777, lists men under guard, with their infractions. The series contains 12 military records of payments for food, supplies, and soldiers pay. Two of these are post-war accounts kept by Jonathan Child and Jonathan Chase, documenting expenses incurred on behalf of the United States during the war, with calculations of interest up to December 13, 1786, and March 1, 1791.
