Recent immigrants and American-born sons were quick to join war efforts during the Spanish American War of 1898 and World War I. They did so again when World War II broke out. Brothers often enlisted together; six brothers from one Gallagher family served at the same time. Priests and doctors answered the call as well. On the home front, many Irish Americans were involved in maintaining a canteen for servicemen at St. John Cathedral. For returning servicemen, the GI Bill offered an opportunity to attend college or even medical or law school--opportunities that young men from working class families would not have had otherwise, and opportunities that they could open up for their children in turn.
