British women's literature of World War I: For much of the twentieth century, a deep ignorance was displayed towards British women’s literature of World War I.  Scholars reasoned that women had not fought combatively, thus, did not play as significant a role as men.  Accordingly, only one body of work, Vera Brittain’s autobiographical, "Testament of Youth", was added to the canon of Great War literature.  Conversely, anthologies published mid-century such as Brian Gardner’s, "Up the Line to Death: The War Poets of 1914-1918", contained no mention of contributions made by women.  Similarly, Jon Silkin’s 1979 anthology, "Penguin Book of First World War Poetry", included the work of only two women, Anna Akhmatova and Marina Tsvetaeva.  However, new research has changed ideological beliefs about the role women assumed in producing authentic accounts of war.  More specifically, in Britain, research attends to an explanation of how women’s war literature shaped feminist discourse during and immediately following the war.
