Upbeat letter delivered to Gen. Phelps by the writer's son, William C. Holbrook, who apparently turned down an offer to join Phelps's staff. The writer, Gov. Holbrook, lavishes praise on Vermont officers and soldiers (including his son), and sends warm wishes for success to Phelps, sharing his conviction that "the Union Cause must triumph." Holbrook concludes with some reflections on the difficulty of being a wartime governor.
