Memorial Day honors those who’ve died while serving in the military. In this episode of BackStory, Ed, Joanne, and Brian look at the many reasons for joining the U.S. armed services - from a sense of patriotism, to escaping poverty, to earning American citizenship. They’ll discuss the struggles of the Continental Army to find enough soldiers during the Revolutionary War and how thousands of Filipinos became American citizens by enlisting in the US Navy after World War II.
