Lincoln's main concern in his Second Inaugural Address was peace.
Lincoln sees the War as the divine retribution for the United State's sin of slavery. He states that both sides wanted to avoid war but one, the South, for its economical reasons, the ownership of slaves, wanted to tear the nation asunder, and the other went to war because they could not let the nation perish, the North. Lincoln wants that people forget their grudges and to together heal the wounded nation. To forget retribution and "with malice toward none, with charity for all" rebuild the torn nation.
d. Lincoln thinks the civil war will be of outstanding significance or importance.
Lincoln refers to the American Civil War (1861 - 1865), which confronted the Union and Confederate Armies. And the Battle of Gettysburg, which had taken place a few months before Lincoln delivered his Gettysburg Address, is recognized as a turning point in the war in favor of the Union cause.
