The First World War was a common experience that many soldiers, of many nationalities, had to endure. Because the devastation and loss of life was so great, no nation’s soldiers were spared from the horrible psychological effects of the First World War.

An example of what the common soldier had to endure everyday can be found in Robert MacKay’s diary entry of September 3rd 1917: “Feeling like nothing on earth, with a rash all over me, even ...
