The march was an opportunity to follow in the footsteps of Union or Confederate soldiers by walking with living historians and park rangers along the paths during the famously ill-fated Pickett's Charge, which brought to a close The Battle of Gettysburg when the Union Army repelled their advance. Taps was first thought to have been played at a military funeral or memorial service in 1862, at the burial of a Union soldier.  The Battle of Gettysburg lasted from July 1-3, 1863 resulting in over 50,000 soldiers killed, wounded or missing.  John Boal Photography
