Let's not forget this date, 1863. Many a young man lost life and limb in the final clashes of Gettysburg.
I'm curious what the temperature/humidity levels were. Some accounts had "Pickett's Charge" of 15,000 Confederates march between 1/2-1 mile across an open field, toward the Union center; both sides wearing wool uniforms, carrying weapons and ammo, getting shelled with cannon snot, until they got close enough for rifles. Truly a surreal moment in our Nation's history and one that should never be forgotten.
