R. J. Manion, A Surgeon in Arms
“ Shell shock is brought about by the effects of severe shelling; by being buried by an explosion of shell or mine; or by the killing beside the sufferer of a companion. In short, these cases are due to the subjection of the nervous system to a strain which it is unable to withstand, making it collapse instead of resiliency rebounding. The extreme cases are pitiable to observe, and are just as ill as if they were suffering from insanity, or delirium tremens. It is doubtful if the man who has suffered from a severe attack of this malady is ever again fit to serve in the firing line. ”
