This chapter explores the First World War poetry of Mary Borden, placing it against the backdrop of her critically acclaimed prose record, The Forbidden Zone (1929). Borden published her poetic responses to her war experience as a post script to this text. Like the other fragments and short stories, these poems draw on her experience with the Hopital Chirurgical Mobile No. 1, inviting the reader to see, hear, smell, and interpret the war along with the poilus whom she treated. Borden’s poems offer a record like no other, often adopting stylistic tropes of modernism to articulate the unspeakable. The chapter also examines some very different wartime poems that document her love affair with her future husband, Edward Spears. Powerful and erotically charged, these poems encapsulate a very different kind of war experience, enabling Borden to speak with a range of poetic voices.
