Prison memoirs often consider the author’s life of crime prior to incarceration and reflect on the behaviors (e.g., greed) or structural violence (e.g., poverty, racism) that led them to the prison. But what happens then, when as in the case of Guantanamo Bay memoirs, there is no “traditional” life of crime, and incarceration is often unfounded? What happens to the prison narrative when the author remains in solitary confinement with their only humane relationships with those in power? It is of little surprise that such memoirs activate provocative and penetrating reading experiences. While Moazzam Begg’s memoir Enemy Combatant (2006) has received some scholarly attention, in part because he featured in lawyer Mark Falkoff’s edited collection Poems from Guantanamo (2007), there has been no scholarly attention to Murat Kurnaz’s Five Years of My Life: An Innocent Man in Guantanamo (2008), Ahmed Errachidi’s The General (2013), and Mohamedou Ould Slahi’s Guantánamo Diary (2015). This chapter will further engage with study groups I conducted with (ex) prisoners in the UK, discussing Falkoff’s collection, to consider how one of the most controversial penal institutions in the post-9/11 world has produced peculiarly intense understandings, conceptualizations, and experiences of incarceration in the form of first-person poetry and prose.
