"In my opinion," he continued, "war is disunion, certain, inevitable, and irrevocable. * * * We have reached a point where disunion is inevitable unless some compromise, founded upon mutual concession, can be made. I prefer compromise to war. I prefer concession to a dissolution of the Union."He asked the Republicans to consent to the reestablishment of the Missouri Compromise line, which he had swept away six years before amid their earnest protestations. He also proposed to establish popular sovereignty by constitutional amendment, such sovereignty to begin when a Territory had 50,000 inhabitants, and, by another amendment, to prohibit future acquisition of territory without a concurrent vote of two-thirds of each House of Congress. His purpose, he said, was not to settle the slavery question, but to expel slavery agitation from the arena of Federal politics forever.
This was his last important speech in the Senate. It was delivered under circumstances of awful solemnity. He seemed not deeply impressed with the gravity of the situation and was still interested in it chiefly as a party problem. He did not expect the baptism of blood that followed, but cheerfully looked forward to compromise and reconciliation. The Northern Democrats might yet rescue the country by mediating a truce between radical Republicans and radical Southern Democrats. In the present state of affairs who, but himself, the chief of these neutrals, could lead this great movement? His mental habits were those of the politician. He saw all event primarily in their relation to party tactics. Now that the earth began to rock beneath his feet, he suspected that it was only a theatrical earthquake and prepared to seize upon every advantage that might be gathered out of the confusion. He could not comprehend the deep and unappeasable passions that rent the Nation.
The grim earnestness of his fellow-countrymen was as inconceivable to him as the demoniac enthusiasm of the great Apostle was to the scoffing Athenians who heard him on the Hill of Mars. But, as the great tragedy deepened and darkened, he quit his political speculations and began to think, not of the success of his party, but of the possibility of saving the Union from imminent wreck.
He returned to Illinois and addressed the legislature, urging energetic support of the war, and on May 1st was welcomed back to Chicago by an immense assembly of all parties. He was escorted to the great hall in which Lincoln had been nominated and there addressed the people. He spoke not as a politician but as a generous patriot. He denounced in unmeasured terms the Southern conspiracy which had resulted in secession and now had ripened into open and bloody rebellion. He saw the treason of the South no longer as a mere element in an interesting political game, but as the blackest of human crimes and an awful menace to the life of the Republic.
"There are only two sides to the question," he said. "Every man must be for the United States or against it. There can be no neutrals in this war; only patriots or traitors. * * * It is a sad task to discuss questions so fearful as civil war; but sad as it is, bloody and disastrous as I expect it will be, I express it as my conviction before God that it is the duty of every American citizen to rally around the flag of his country."Not long after his return home he was stricken with serious sickness.
The disease was not of such a character that it was expected to prove fatal, but the highest medical skill and most tender nursing were unavailing. The truth was, although unsuspected, that his vital energies were completely exhausted by the enormous labors and deep agitations of the past ten years. He had just passed his 48th birthday but was already gray and prematurely old. He had dwelt amid the tempest for twenty years and had felt more of severe strain than most men who had seen the Psalmist's three score years and ten. When told that his end was near, and asked what message he would send to his boys:
"Tell them," he said, "to obey the laws and support the Constitution of the United States."On the morning of June 3rd he died. His remains lie buried in Chicago on the shore of Lake Michigan, a spot fitly chosen as the last resting place of this most ceaselessly active and inexhaustibly resourceful of American statesmen.
