May Sinclair's emotionally-charged journal recording her short time near the Belgian front lines offers a highly personalised account of a female presence in war. This essay explores the roles performed and the spaces encountered by Sinclair and the other women she met. Women's complex relationship with war zones, spaces and places is revealed through personal experience, masculine attitudes in evidence and Sinclair's own modernist writerly techniques.Keywords: May Sinclair, World War I, Women's work at the front line, access to the front for women, women writers of WW1, interior and exterior war zones, psychological responses to WW1, shell shock, war reporting, Sinclair's war novels and poetry, critics' views of Sinclair's writing.
