Mental weakness, with insufficient school and theoretical knowledge but with the ability to assimilate practical ideas, though not knowing how to read, write or calculate; seems to have earned his living in several lines. “As a soldier, he does not know the insignia of the different ranks but understands how to obey a superior officer. Understands a gun and can tell a _chargeur_ from a _Le Bel_ gun. Moreover he seems to be perfectly stable, fixed in his wishes, persistently and intelligently wants to go to the front and kill Boches. He appears to be well disciplined and educable. Although feebleminded, he appears to us able to be useful at the front, though he should not be employed in any undertaking requiring initiative or foresight.” An imbecile, superbrave. =Case 36.= (PRUVOST, 1915.) A loquacious, active fellow, 22, with very slight school knowledge and no idea of military ranks (treated his superiors like his comrades), was often punished in the barracks. He did not get on well with his instructors. His activities were never interrupted by any obstacles or by derision. He kept singing and talking enthusiastically during the mobilization. He was the butt of his section. At Dinant he did very well; though his section was losing a good many men he remained calm. He was careless of danger and remained at his post firing ceaselessly at the enemy and giving a magnificent example to the few comrades who remained with him. In fact, he remained so long in his shelter that he was surrounded and taken prisoner. He escaped, swam the Meuse and got back to his regiment. An imbecile of service in barracks work. =Case 37.= (PRUVOST, 1915.) A farmer, 36 (father alcoholic, mother always sick, two brothers at the front; patient had typhoid at an unknown age; had gone to school at 13 but “learned nothing”; worked in fields with his brother who gave him some pennies on Sunday), was put into the auxiliary service by the Council at 20. Patient said he was not strong enough for this service. In 1914 the Council reconsidered the case and put him into a regiment of infantry. He could not be given military instruction or execute the most simple drilling manual. He said that 4 plus 2 equalled 7; 4 plus 3 equalled 5. He was of an excellent character, very docile and easily directed. He did all his comrades’ barracks work and was very proud because, as he said, “I do everything they tell me to do.” He was happy in working, everybody was good to him, but he had no comrades. He had no general knowledge and knew nothing about the war but that they were fighting the Boche. _Re_ imbeciles, Colin, Lautier and Magnac found amongst 1000 soldiers entering Villejuif, 53 imbeciles. Twenty-four of them had been either exempt or retired at the outset of the war, when military surgeons had reviewed them and considered them fit for service. Several of the 29 others also had shown previous evidence of imbecility.
