This collection contains three letters written by Delia Brown Herbert, a resident of Bergen (Genesee County), New York, during the American Civil War. All of the letters are addressed to her sister, Achsah Smith (aka Mrs. T. F. Smith), of Lockport, New York. The letters relate overwhelmingly to Herbert's concern regarding the whereabouts and wellbeing of "Hank" (presumably her husband, Henry E. Herbert, serving in Battery M, 1st New York Light Infantry) during the intervals in which she has had no word from him. Accompanying one of the letters is a stamped envelope.
