Things were relatively quiet until 1919, when returning local servicemen, angry over perceived insults from Yale students, attacked the Old Campus. Finding the gates locked, they broke hundreds of windows and moved on to theatres and restaurants in the town, assaulting any students they could find. In 1959, a student snowball fight on city streets got out of hand and resulted in arrests by New Haven police. Students then pelted police officers with snowballs during the St. Patrick's Day parade. The so-called "snowball riot" attracted national media attention – a preview of the tumultuous 1960s.
