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).

The most devoted chronicler of the campaign, however, is the younger William L. Stone (b. 1835), who published Reminiscences of Saratoga and Ballston in 1875, an article on "Burgoyne in a new light" in The Galaxy (v. 78), and one on the campaign in Harper's Monthly in 1877 (vol. lv. p. 673), and in the same year the most important work on the subject yet produced, The Campaign of Lieutenant-General John Burgoyne and the Expedition of Lieutenant-Colonel Barry St. Leger, which draws from every important help to the study of the military movements which had been so far brought to light. In the next year (1878), Mr. Stone prepared the Memoir of the Centennial Celebration of Burgoyne's Surrender, Schuylerville, Oct. 17, 1875. It included an historical address by Mr. Stone himself, others by Horatio Seymour and George William Curtis.[860]

The English later writers have been in the main fair in their statements. Mahon (vi. 191), while praising the army of Gates, denies him the merit of its successful conduct, giving it essentially to Stark and Arnold. The American student finds little to question in the unusually impartial narrative embodied in Edward Barrington De Fonblanque's Political and Military episodes in the latter half of the Eighteenth Century, derived from the life and Correspondence of John Burgoyne (London, 1776).[861]

On the German side the main sources are Max von Eelking's Die Deutschen Hülfstruppen im nord-amerikanischen Befreiungskriege, 1776-1783 (Hannover, 1863,—2 vols.), who gives chapters 7 and 8 to this campaign; the same writer's Leben und Wirken des Herzoglich-Braunschweig'schen General-lieutenants Friedrich Adolph von Riedesel (Leipzig, 1856,—3 vols.) and Generalin von Riedesel's Berufs-Reise nach Amerika (Berlin, 1801), both of which Riedesel memoirs have been translated by W. L. Stone.[862]

The succession of battles and movements preceding the final surrender of Burgoyne have been well mapped.[863]
