1920’s - Hard Times - In the years following World War I, college-based military programs fell from favor nationally as well as at St. Thomas. In 1922, military training became optional at the college level and within three years only 15 students participated. Once known widely for it smartly uniformed cadets, St. Thomas was now in search of a new identity.

1940’s - Shot to pieces - "The war has shot the college to pieces," said Father James Moynihan in 1943, his second-to-last year as St. Thomas' president. With so many students now serving in the war effort, the college's enrollment plunged to fewer than 100. The campus remained open in large measure thanks to a naval contract that brought more than 700 cadets to campus for the V-12 officer-training program. Shortly after America was swept into war in late 1941, the campus newspaper carried a feature, "With the Tommies in Arms," with news of the more than 5,000 students and former students who served during World War II. Father Vincent Flynn, who in 1944 became the first alumnus to serve as president, successfully guided St. Thomas through a decade of tumultuous change during and after World War II. "War Vets Jam St. Thomas Campus" read a 1946 newspaper headline. Thanks in part to the G.I. Bill, enrollment topped 2,200. To accommodate the surge, the college acquired 26 government-surplus buildings, including 20 double-dwelling huts for married faculty and veterans. "Tom Town," as it was called, was located along Cleveland Avenue on the east side of campus. The Air Force ROTC program began on campus in 1948.
