This article offers an analysis of mnemonic traces in Galadio, Didier Daeninckx’s 2010 novel. I demonstrate that by fictionalizing the history of the persecution of Afro-Germans under National Socialism, the novel exposes antiblackness as a neglected phenomenon of the Third Reich. Synchronously, applying Michael Rothberg’s theoretical framework, the article discusses the dialogue between Jewish and Afro-German legacies of violence in the novel, as well as the intricate relation between colony, camp and what Paul Gilroy defines as camp mentality. Furthermore, I argue that Daeninckx engages with French colonial aphasia: in my interpretation, his oblique approach to the French imperial past conveys its simultaneous presence and absence, which is key to disabled memory. Finally, I focus on the ethics of commemoration in Galadio, which claims space for black soldiers in French collective memory of the two world wars, yet at the same time challenges imperial loyalties and homogeneous approaches to French national identity.
