Thanks for the kind words. I have always been fascinated by the coincidences in the CW, Wilmer McLean's in particular. This song focuses on the 4th Virginia, also known as the "Wythe Grays". They were Stonewall Jackson's brigade, and fought from Manassas through Gettysburg, and were present when Lee surrendered at Appomattox Court House.
BTW, today marks the third day of Gettysburg, the day of Pickett's Charge, 150 years ago.
