The evidence
“The young men returning from the field to the campus, brought with them a blended vigor and loyalty of character which have made the history of the College after the war a new era in its life. During the war, the course of the College had gone on without interruption, except that the Commencement of 1864 was omitted, the entire Senior Class, as well as the Professor of Rhetoric, being in camp. But the classes were composed, necessarily, of young men under military age, though the great events of the time were preparing them to sympathize in the high purposes with which their elder fellows returned to complete their training to serve the country which they had helped to save.”
