@memdaypbs: On this day in 1914, Austria-Hungary declared war on Serbia, launching the world into what would be known as The Great War. During World War I, two million American soldiers would leave home to serve their country–over 116,000 of them would lose their lives by the end of the war. From the 1998 concert, actor Richard Dreyfuss shares with us that time of patriotism and sacrifice, paying tribute to all who served during the WWI era. #MemDayPBS #MemorialDay #RichardDreyfuss
