Strategy, Sabotage and Spying
In addition to these two case studies, there are several related case studies which can be found in other themes: the innovative technology of the First World War is discussed in relation to trench maps, aerial photography and trench raids in the three case studies included in the theme Mapping and Photographing the First World War. There are two other case studies relating to spying: C.K. Ogden was spied upon during World War I -- see A Voice of Reason: C.K. Ogden and the Cambridge Magazine included in the theme Telling the Truth. Also, four women were executed as spies -- see Shot at Dachau: Four Young Women Who Died for Their Country under the theme Women and War.
