Correspondence of Oliver Perry Newberry with his wife, Lydia Elizabeth McCorkle Newberry (Lizzie), his mother, Cornelia Perry Pangborn Newberry, and brother, Walter Cass Newberry, mainly pertaining to Newberry's Civil War military service in Missouri, and to a lesser extent in Mississippi and Tennessee; his activities immediately preceding and following the war; and children and other family matters. Newberry's Civil War letters express surprise at abolitionist sentiment in the North; talk about his desire to prove himself in battle and worthy of promotion; request epaulets, sashes, swords, and other trappings of an officer's rank; and express patriotic sentiments. The letters discuss conflicts between secessionists and unionists in Missouri; the aftermath of the Battle of Shiloh, and skirmishing during the siege at Corinth. Two letters have accompanying envelopes with patriotic vignettes. After the war in two letters to Walter Cass Newberry, Newberry's wife Lizzie graphically describe his inability to adapt to civilian life, citing ill temper, constant use of profanity, excessive drinking, and unwillingness to work. There are also two 1890's letters from former Norwegian servant Hannah Mathison to son Walter Franklin Newberry that concern her return to Chicago.
