With the declaration of war in 1914 scores of men were mobilised and volunteered for Lord Kitchener’s army. One of the most important ramifications of the First World War was that it provided the opportunity for women to work in industries which were previously barred to them. This publication provides an authoritative list of the trades and processes in which women were successfully employed in temporary replacement of men. In addition, the illustrative plates in this publication offer a snapshot of the roles of women during the 1914-1918 conflict.
