Knox College's service flag is displayed on Old Main. The image was taken some time near the end of the war. The number 642 represents the number of Knox men serving in the armed forces during the war (the final number was 660).
In this photo inset in the Knox College yearbook, a photograph of S.A.T.C. students is captioned, "Yes, they sometimes work at drill." (It also features a student kneeling next to a squirrel with the caption, 'Careful, Hinman - He'll bite you.')
On this page of the Knox College yearbook, it is noted that Robert F. Midkiff, a junior participating in Sigma Delta Chi (the professional journalistic fraternity at Knox), was then part of the armed service.
