In his own conduct, his guiding principle was fidelity to his official duty as he read it in the Constitution and the laws. He felt the specific, supreme task laid upon him to be the restoration and maintenance of the Union. And to succeed in that, he knew he must rightly interpret and enforce the general sentiment and desire of the loyal people. If he let them become so divided as to no longer act together, the cause was lost. And to follow any personal opinion or conviction of his own, in disregard of his official duty, or in defiance of the popular will, was to betray his trust.

It was under these conditions that Lincoln dealt with slavery. No man more than he detested the institution, or desired its removal. But he felt that he had no right to touch it, except as empowered by the Constitution and the laws, or as guided by the supreme necessity of saving the nation's life. Beyond that he had no authority. Beyond that, his position toward slavery must be like that of a President toward, for example, a system of religion which he believed to be false and injurious. Be he intensely orthodox, believing infidelity to be the road to hell,—yet he must not as President, put a straw across the path of the free-thinker. Be he as heretical as Thomas Jefferson, he must not as President, any more than did Jefferson, lay a finger on the churches. Just so did Lincoln feel himself restricted as to slavery,—he could not touch it, except as the civil laws brought it within his province, or unless as supreme military commander the laws and necessities of war brought it within his authority.

Congress soon proceeded to discuss questions about slavery. Sumner, the foremost leader of the radicals, proposed resolutions, in February, 1862, declaring that the seceded States had by their acts extinguished their State organizations and relapsed into a territorial condition, subject only to Congress; and that slavery within them, existing only by a local authority now defunct, was thus abolished. Congress would take no such ground as that. But, as within its proper sphere, it abolished slavery in the District of Columbia, in April, 1862, giving compensation to owners at a maximum rate of $300 for each slave. And in the following June, it abolished slavery in all the national territories,—thus giving full force to the cardinal doctrine of the Republican party up to the war. But the war had inevitably brought a more radical issue to the front,—the question of slavery in the States.

Under the name of a confiscation act, Congress passed a law, July 17, 1862, which declared freedom to all slaves of convicted rebels; to slaves of rebels escaping within the army lines, or captured, or deserted by their masters; and to all slaves of rebels found in places captured and occupied by the Union army. This came near to making the abolition of slavery follow exactly the progress of the Union arms. But, leaving untouched the slave property of loyalists, it spared the institution as a system.

Lincoln, in many ways a man of the people by his convictions and sympathies, in other aspects towered in solitude. He was almost unique in that he could fight—fight if need were to the death,—with no spark of hatred in his heart. In the midst of war he was a devoted peace-lover. To an old friend, though a political opponent, Congressman D. W. Voorhees, of Indiana, who called on him at the White House, he said with a pathetic look of anxious pain: "Voorhees, doesn't it seem strange that I should be here—I, a man who couldn't cut a chicken's head off,—with blood running all around me?" While he was overseeing campaigns, selecting and rejecting generals, learning the business of a commander, keeping touch with all the great matters of administration, besieged by office-seekers, importuned by people in all manner of private troubles,—he found intervals in which to devise ways out of the horrid business of war, ways that might lead both to peace and freedom.

The key of the situation he thought lay largely with the border States,—Maryland, Missouri and Kentucky,—all of them formally in the Union, but their population divided, sending recruits to both armies, and with hopes in the Confederacy that they might be entirely won over. If they could be bound faster to the Union, if at the same time they could be helped to make themselves free States,—then might the Union cause be mightily helped, and at the same time the work of emancipation be begun. Aiming at this result, Lincoln sent a message to Congress, March 6, 1862, proposing this resolution: "That the United States ought to co-operate with any State which may adopt gradual abolishment of slavery, giving to such State pecuniary aid, to be used by such State, in its discretion, to compensate for the inconveniences, public and private, produced by such change of system." He urged this with special reference to its application in the border States; and, inviting the Congressional members of these States in a body to the White House, he pleaded with them earnestly to support the resolution, and apply the plan. They listened, but were non-committal. Congress received the plan coolly. The Radicals were little in the humor of compensating slaveholders, and the Conservatives apprehended a progressive attack on slavery. But the President's influence triumphed; the resolution passed in mid-April; and the nation pledged itself to assist compensated emancipation in any State that would adopt it.

Nothing came of it. The border States did not move. Three months later, July 12, their delegations were again invited to the White House. The situation was at the gravest; McClellan's army had been baffled in the desperate seven-days' fight; factions at the North were growing hot. Lincoln pleaded reasonably, movingly, that they would bring decisive help to the national cause, by committing their States to emancipation, with help from the nation, gradually if they pleased, with colonization if they desired—peace, union, freedom, all lay that way! Two days they took to make answer, and then of the twenty-nine members only nine were favorable; the rest with one accord began to make excuse,—and that hope failed.

Events were forcing on the question of slavery. In the previous May, General David Hunter, in South Carolina, finding himself with 10,000 fugitives in his camps, whom the laws forbade him to return to their masters and did not permit him to hold as slaves, met the difficulty by a proclamation, declaring that the martial law of the United States was incompatible with slavery, and the slaves in his military district—South Carolina, Georgia and Florida,—were set free. Again the President overruled his subordinate, but in the proclamation he distinctly said that the question of emancipation as a military necessity belonged to himself as commander-in-chief. It was a note of warning. Twenty years before, John Quincy Adams had written,—and the words came from a conservative statesman of the highest standing: "I say that the military authority takes for the time the place of all municipal institutions, and slavery among the rest"; and had elaborated and reiterated the doctrine that in case of war slavery might be abolished by the commander. These statements had lately been recalled; the action of Fremont and Hunter had given life to the idea; and Lincoln now intimated that he might yet assume this authority.

Party divisions had soon reappeared at the North. The Democrats were not harmonious; a part called themselves "War Democrats," and a part were ready to let the South go, or went as near that as they prudently could; now one and now the other faction controlled the party according to time and locality. The Republicans were more united, yet among them was a cleavage between conservatives and radicals; the one taking for their watchword, "the Constitution as it is and the Union as it was"; the other eager to see the war turned against slavery; and both claiming the President, and jealously watching any leaning on his part toward their rivals.

There was developing at the North a profound sentiment for attacking slavery. The war was protracted beyond all early expectation; it was costly, bitter, woeful. What was to be at last the recompense for all this blood and tears? Was there, if victory came at last, to be with it no advance, nothing but the old Union, half slave and half free? For nothing better than this were sons, fathers, brothers, husbands to be sacrificed? Was the nation crossing a Red Sea of anguish only to emerge into the old bondage? Rather, let us fight at once for union and for liberty!
