Question 0100110:
" In your hands, my dissatisfied fellow-countrymen, and not in mine, is
the momentous issue of civil war. The Government will not assail you.
You can have no conflict without being yourselves the aggressors. You
have no oath registered in heaven to destroy the Government, while I
shall have the most solemn one to 'preserve, protect, and defend' it. We
are not enemies, but friends. We must not be enemies. Though passion
may have strained it must not break our bonds of affection. The mystic
chords of memory, stretching from every battlefield and patriot grave
to every living heart and hearthstone all over this broad land, will
yet swell the chorus of the Union, when again touched, as surely they
will be, by the better angels of our nature."
