This article will argue that the current historiography considers the 'public school experience' of the First World War too narrowly, and will emphasise that boys from a wide range of establishments experienced the war in a similar fashion to those at elite public schools. It will do this through a case study of the alumni of the Perse Grammar School, Cambridge. By approaching the experience of Perseans in a thematic fashion it will shed new light on how the alumni of schools just below and developing towards full public-school status were affected by the war, an area hitherto not fully explored.
