Nigerian female war writers design their stories to revolve around ordinary people especially women and children who were subjected to the horrors of the war without their consent. In order to achieve their communicative purposes of creatively telling their stories, they used language to integrate different techniques such as Role reversal, Creative recollection, Flashback, African story telling technique, Transliteration, Proverbs, Subjectivity in presenting viewpoints, search or quest motif into their novels. Using formalistic approach, the study gave a close reading of the novels by appraising some of the techniques used by Chimamanda Adichie in Half of a Yellow Sun, Akachi Adimora-Ezeigbo in Roses and Bullets and Buchi Emecheta in Destination Biafra to determine how effectively they have applied them to show their creative competence. The study concludes that the techniques were successfully utilized through the authors’ artistic use of language and then recommends that other young writers should adopt these authors use of literary techniques and apply them in writing because it heightens the effect of the narrative by creating suspense and enhancing their thematic focus.
