Winthrop Sargent was an author. He was the grandson of Winthrop Sargent.
He wrote for the periodical press, especially on genealogical and historical subjects. His publications include History of an Expedition against Fort Duquesne in 1775, under Major-General Braddock, edited from Original Manuscripts, which was commended by George Grote, the historian, and was described by Washington Irving as "ably edited, with an admirable introductory memoir" (Philadelphia, 1855); The Loyalist Poetry of the Revolution (1857); The Journal of the General Meeting of the Cincinnati (1858); Loyal Verses of Joseph Stansbury and Dr. Jonathan Odell, with Introduction and Notes (Albany, 1860); Life and Career of Maj. John André (Boston, 1861); and Les États Confédérés et de l'esclavage (The Confederacy and Slavery; Paris, 1864). For many years he was engaged in preparing a catalogue raisonné of books relating to America, which he left unfinished.
Very Victorian, and uncritically repeats things that may not be true, but still useful and recommended, and I think a serious attempt to write a real biography, even if it's not entirely successful by modern standards. Sargent had less access to a lot of primary sources than we do, especially the English ones, but he also lived close enough to the time of the Revolution that he was able to talk to people who had known André or whose parents had known André.
Every time, I read the biography of Major John André, I keep cheering for a reprieve from George Washington. André was hung because of Benedict Arnold's escape to Britain.
