This introduction shows how US Army officers used reports and other official correspondence to deploy specific narratives, constructing an identity for themselves and their institution premised on protecting women. This previously unacknowledged process erased or reframed evidence of women’s wartime activities. Yet, acknowledging this process reveals how paternalism shaped army culture; naturalized officers’ authority over enlisted men; and provided a cultural foundation for military law, policy, and strategy. Breaking up the fictive separation of women and war shows how army culture developed between 1835 and 1848. It also illuminates how that culture shaped, rather than removed, violence against women.
