The fall session of 1861 opened with a slight increase of students, but they were younger than usual,--from fourteen to seventeen years, and not as well prepared as before the war. Parents sent young boys to school to keep them out of the army; many went to get the military training in order that they might become officers later; the state needed officers and encouraged military education. The university was required to furnish drill-masters to the instruction camps without expense to the state. As soon as the boys were well drilled they usually deserted school and entered the Confederate service. This custom threatened to break up the school, and in 1862 all students were required to enlist as cadets for twelve months, and were not permitted to resign. Yet they still deserted in squads of two, three, and four, and went to the army. Recruiting officers would offer them positions as officers, and they would accept and leave the university. The students refused to study seriously anything except military science and tactics. Numbers refused to take the examinations in order that they might be suspended or expelled, and thus be free to enlist. In 1862-1863, 256 students were enrolled,--more than ever before,--but mostly boys of fourteen and fifteen. The majority of them were badly prepared in their studies, and it was necessary to establish a preparatory department for them. In 1863-1864 there were 341 boys enrolled--younger than ever. At the end of this session the first commencement since 1860 was held, and degrees were conferred on a few who had enlisted and on one or two who had not. The enrolment during the session of 1864-1865 was between 300 and 400--all young boys of twelve to fifteen. The cadets were called out several times during this session to check Federal raids. Little studying was done; all were spoiling for a fight. When Croxton came, one night in 1865, the long roll was beaten, and every cadet responded. Under the command of the president and the commandant they marched against Croxton, whose force outnumbered theirs six to one. There was a sharp fight, in which a number of cadets were wounded, and then the president withdrew the corps to Marion in Perry County, where it was disbanded a few days later. It was now the end of the war. Croxton had imperative orders to burn the university buildings, and they were destroyed. There was a fine library, and the librarian, a Frenchman, begged in vain that it might be spared. The officers who fired the library saved one volume--the Koran--as a souvenir of the occasion.[591]
