Good luck. Union corps commander losses like Sedgwick, Reynolds, McPherson, and Reno were legitimate kills by the confederates.
Sedgewick's last words were "They couldn't hit an elephant at that dist..." True story
I'm just kidding....I'm sure someone will have a reason why what you state was so.
Many a combatant has thought he was out of range...to his chagrin
You should go to AR-15.com and check out the remains of a Taliban/Al Queada gent who thought he was out of range of a MacMillan .50BMG....stuck his little raghead up thru the window opening and .....well....the results are not too pretty. Best to view it on an empty stomach.
