This article examines the 1 July 1992 massacre of 18 Indigenous males and the concurrent cutting off of the hair of their wives and/or female kin carried out by the Shining Path in the Andean village of Huamanquiquia (Fajardo province, Ayacucho region). Based on first-hand accounts of the Maoist insurgents and the Indigenous women, I frame these events as a local case study of gendered atrocity that was experienced differently by men and women, focusing on the symbolic violence of haircutting. While this atrocity reflects some well-known patterns seen in other armed conflicts, it is shaped by two key factors specific to the time and place: first, particular understandings of the significance of hair within broader Andean cosmologies; second, tensions within the Shining Path movement at a key juncture in the war. I show that the Andean insurgents knew about the symbolic dimensions of haircutting, a crime against the integrity of the human body–soul – one understood to cause endless suffering in the journey to the afterlife in the Andean worldview – but they underplayed them. From this viewpoint, haircutting meant the mutilation of women’s physical integrity, with psychological, social and gender implications.
