Select the correct answer. What is the main idea of this excerpt of Abraham Lincoln’s Second Inaugural Address?

On the occasion corresponding to this four years ago, all thoughts were anxiously directed to an impending civil-war. All dreaded it — all sought to avert it. While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without war — seeking to dissolve the Union, and divide effects, by negotiation.
