In the waning days of 1862, Union and Confederate troops set up camp within earshot of one another in Murfreesboro, Tennessee. Christmas had just passed, and for many of these battle-wearied young soldiers the holiday season was a melancholy reminder of the families and loved ones they'd left behind. Bands from both camps played patriotic songs in an attempt to raise spirits, a musical duel that presaged the bloody battle to come. Then, something extraordinary occurred. One of the bands began playing a popular sentimental tune called “Home Sweet Home.” Soon, bands from both sides picked up the tune, and before long thousands of Northern and Southern soldiers had joined together in song.
