This collection consists of a single letter written by Henry E. Herbert, a soldier in Battery M, 1st Regiment, New York Light Artillery during the American Civil War. Dated June 22, 1863, at Headquarters, Camp D, the letter is addressed to Herbert's brother, Thomas M. Herbert, of Lockport, New York. Herbert writes of his brother's health with encouraging words. ("[T]homas you must not dispair yet keep up good curridge you may get well again," he writes.) Herbert also mentions a battle that had occurred the previous day at "Aldee" with "[a]bout four thousand cavelery and two or three battreys that licked the rebs bad" and reportedly captured a Confederate gunboat. The reference may be an erroneous account of the Battle of Aldie, Virginia.
