There are among the copies of the Lincoln Papers in the _Sparks MSS._ (xii.) various letters, etc., respecting the campaign against Burgoyne. The earliest is one from Gen. Schuyler to Lincoln, dated at Saratoga, July 31, 1777, and the last is one from Lincoln to Gov. Clinton, Oct. 5, 1777, expressing anxiety lest Putnam should not be able to resist Gen. Clinton, to whom Burgoyne in his straits was looking for relief.[857] At a later day Lincoln wrote a long letter from Boston, Feb. 5, 1781, to John Laurens, recounting his part in this campaign from the time of Gates's taking command to the date of Lincoln's being wounded, Oct. 8th (Sparks's _Corresp. of the Rev._, ii. 533). Various letters of Henry Brockholst Livingston during the Northern campaign of 1777 (June-Aug.), only parts of which are printed in Sedgwick's _Livingston_, are among the papers of Gov. William Livingston, which, when Sparks made his copies in 1832 (_Sparks MSS._, lii., vol. iii.) were in the possession of Theodore Sedgwick, Jr. Other letters will be found in the _Trumbull MSS._ (Mass. Hist. Soc.)[858] The campaign of Burgoyne has necessarily made part of the labors of the general historians. Gordon and Ramsay were among the earliest, on the American, and Stedman (i. ch. 16) on the English side. Of the later writers, Bancroft gives it three chapters (21, 22, 24) in his original edition, and four in his final revision[859] (10, 11, 12, 13). Lowell finds it an important section of his history of the German auxiliaries (_Hessians_, p. 221, etc.). The lives of principal participants, like Arnold, Lincoln, Gates, and Schuyler on the American side, cover it. A recent life of Morgan, _The Hero of Cowpens_, by Rebecca McConkey (N. Y., 1881), would claim for the Virginian the praise which is usually given to Arnold. The general surveys of Marshall (iii. ch. 5) and Irving (iii. ch. 9-22) brought it within the scope of their lives of Washington; and J. C. Hamilton's _Republic of the United States_ includes it. Local aspects are treated in Dunlap's _New York_; Holden's _Queensbury_ (p. 433); Hollister's _Connecticut_; Hinman's _Connecticut during the Revolution_ (p. 112); and Mrs. Bonney's _Historical Gleanings_ (i. 58). Robin's _New Travels_ (letter 12) gives the current accounts prevailing a little later. The earliest considerable monographic narrative was Charles Neilson's _Original, Compiled and Corrected Account of Burgoyne's Campaign, and the Memorable Battle of Bemis's Heights, September 19, and October 7, 1777, from the most Authentic Sources of Information_, etc. (Albany, 1844).
