“The usual direct result of the shock [from a shell or bomb explosion] is ‘loss of consciousness’ or ‘loss of memory’ ” (461).

“Such disorders … are not immediately attributable to violence, gas poisoning, or other physical causes. They are the result of a functional inhibition, which is usually traceable to intense fear or horror, but which may … occasionally arise in circumstances where consciousness has been so instantaneously lost that the emotional effects of the shock have not been actually experienced by the patient” (466).
