My favorite is the quote on the wall as you exit the visitor's center and move out onto the cemetery grounds
IF EVER PROOF WERE NEEDED THAT WE FOUGHT FOR A CAUSE AND NOT FOR CONQUEST, IT COULD BE FOUND IN THESE CEMETERIES. HERE WAS OUR ONLY CONQUEST: ALL WE ASKED … WAS ENOUGH … SOIL IN WHICH TO BURY OUR GALLANT DEAD.
