Aura Lea was published by Poulton, an Englishman who had come to America with his family as a boy in 1838, and Fosdick in 1861. It was a sentimental ballad at a time when upbeat and cheerful songs were more popular in the music halls. It became popular as a minstrel song, and the tune was also taken up by the U.S. Military Academy as a graduating class song, called "Army Blue"; new lyrics by L. W. Becklaw were sung to the original melody.
