Look what someone inserted at the Highwater Mark at Gettysburg! What shall we make of this? I suspect that a pro-Confederate secretly defiled the Union's most important spot at the battle - the defeat of Pickett's Charge (some call it Longstreet's Assault) on Cemetery Ridge. For shame. I suggest that someone put a U.S. flag on a similar rebel spot, like Jefferson Davis' grave - to signify his years of loyal service to the Union before he rebelled.
