_Re_ prisoners, Imboden found amongst 20,000 French soldiers taken prisoner at Verdun after the severest drum fire and strain, only five neurotic cases (data of Mörchen), and Wilmanns found but five neurotic cases amongst 80,000 prisoners. Lust reviewed 20,000 war prisoners in Germany and found singularly few instances of neurosis. Shunkoff notes, however, that there are a number of psychotic cases amongst the prisoners because the _mentally_ diseased who do not disturb the military routine are kept in the line. Bonhoeffer found amongst Serbians taken prisoners by Germany, emaciation, atrophy, heart disease, and frequently tuberculosis. (See Case 166.) Bonhoeffer noted the absence of psychoses amongst these Serbians, drawing the general conclusion that campaign stress was unable to bring out psychoses. But, although the exhaustion psychoses are not found, there are exhaustion neuroses or states of acute nervous exhaustion, characterized by somnolence and depression, followed by a mild degree of overemotionality. vum Busch states that interned German civilians have gone into psychosis frequently. It is said that one in 10,000 war prisoners in Germany has committed suicide. Bishop Bury found at Ruhleben 60 or 70 cases of psychosis. X. PSYCHONEUROSES Hallucination in the field (surprise by _BOCHES_); scalp wound: Three psychopathic phases--(_a_) over-emotionality, (_b_) obsessions, (_c_) loss of feeling of reality (victim a “constitutional _intimiste_”). =Case 170.= (LAIGNEL-LAVASTINE and COURBON, July, 1917.) A cashier, 31 (of rather weak constitution but without hereditary or acquired mental taint--a religious man and for religious reasons chaste, always given to metaphysical speculation and introspection, but on the other hand, much interested in sports and very sympathetic with English manners), was about to go to live in the country on the advice of his physician when the war broke out. He was called to the colors and shortly lost his tendency to bronchitis, put on flesh, and felt delighted with his situation. After almost two years of effective service, June 2, 1916, when his troop was cautiously advancing into a trench at the end of which they might be taken by surprise, suddenly the officer cried, “_Sauve qui peut!_ _The Boches are on us!_” The patient remembered seeing Germans emerge from every side, remembered his fear, how he had turned about and crossed over a palisade, and then no more until he found a scalp wound being staunched by his comrades in the trench. He put on his own dressing and followed his comrades on foot.
