I want to know the answer to the following question:
Between 1939 and 1949, how many military officers and personnel were trained on the Evanston and Chicago campuses?
All the background I'm provided with is that "Relations between Evanston and Northwestern were strained throughout much of the post-war era because of episodes of disruptive student activism, disputes over municipal zoning, building codes, and law enforcement, as well as restrictions on the sale of alcohol near campus until 1972.". Is that enough to answer the question?
