GETTYSBURG – We are met on a great battlefield of the Civil War.It was here 150 years ago the war turned. And it was here, four months later, that a 270-word speech transformed the war from a struggle to save the Union to one to save the soul of the country.Many acts of heroism occurred here, most of them lost to history. Many acts of folly and futility occurred here, one of them (Pickett's Charge) preserved in a thousand histories and in a nation's collective memory.
