no were near sufficient to get a bullet to fly close to straight down.I live near the Spotsylvania battlefield. The marker where Reynolds supposedly fell is at an elevation of 257 ‘. Laurel hill, where sharpshooters were posted is 282’. Add a possibility that the marksman was in a tree would boost the elevation on Laurel hill at least 10-15 feet.
I said supposedly where Reynolds fell because the exact spot was in question when the marker was placed, but assuming it was within a dozen or so feet doesn’t change the elevation one iota.
If we where talking straight lines. Then at 900yards the shooter would need to be 900 yards up in the air to get a 45 degree downwards angle.
Obviously a bullet fly in a parabolic arch so a bit less can do it, but it still don't change the physics. For a bullet to hit the head and then the body the shooter would have to be way higher than a hill and a tree.
Or the target was bending forward...
or most likely the bullet got deflected by the skull down into the body.
