Context: Lincoln spoke in solace for all who fought upon this field; and the years have laid their balm upon their wounds. Men who wore the blue and men who wore the gray are here together, a fragment spared by time.

Lincoln was commander-in-chief in this old battle; he wanted above all things to be commander-in-chief of the new peace. He understood that battle there must be; that when a challenge to constituted government is thrown down, the people must in self-defense take it up; that the fight must be fought through to a decision so clear that it is accepted as being beyond recall.
