This chapter looks at the gendered and sexual violence inflicted by the Irish army, known then as the National Army, on militant women who rejected the 1921 Anglo-Irish Treaty, which ended the Irish war of independence and led to the formation of the Irish Free State. The contribution of these militant women to the guerilla war fought by anti-Treaty republicans during the Irish civil war was vital and recognized as such by the State and the National Army. The use of violence—physical, gendered, and sexual—to curtail the threat they posed was deliberate, systemic, targeted, and tactical. Hundreds of female militants were violently abused in prisons and many more brutalized during attacks on their homes and communities. However, this violence, while particularly traumatic as it was former comrades who carried it out, was on a continuum of the gendered and sexual violence committed by the British Crown Forces on militant republican women during the war of wndependence from 1919 to 1921.
