Psychiatric battle casualties: an intra- and interwar comparison.
BACKGROUND
Psychiatric casualties are recognised as an important and inevitable feature of modern warfare. At the beginning of the 20th century they were scarcely acknowledged and still less treated. Today, as a result of lessons learned in the First and Second World Wars, numbers can be predicted on the basis of battle intensity and effective clinical interventions applied.


OBJECTIVE
To discover more about the factors that cause psychiatric casualties and their relationship to total battle casualties.


METHODS
A survey of historical War Office reports and the papers of Royal Army Medical Corps psychiatrists has provided both statistics and treatment strategies.


RESULTS
Reported psychiatric casualties were low in the Boer War, influenced, in part, by the misdiagnosis of psychosomatic disorders. Their incidence rose appreciably in the First World War with the identification of shell-shock and neurasthenia. The Second World War saw the collection of accurate data, and combat stress was treated efficiently, although few soldiers returned to fighting units.


CONCLUSIONS
A constant relationship exists between the incidence of the total killed and wounded and the number of psychiatric casualties, mediated by the nature of the fighting and quality of the troops involved.
