General Fremont was in command in Missouri. He was ardent and uncompromising, and in August, 1861, he issued a drastic proclamation, declaring the State under martial law, threatening death to all taken with arms in their hands, and giving freedom to the slaves of all rebels. The President remonstrated by letter against this too heroic surgery, and when Fremont declined to modify his order, used his authority to cancel it. The public reception of the incident marked and heightened the growing division of sentiment; the conservatives and especially the border State men, were alarmed and indignant at Fremont's action, while he became at once a favorite of the strong anti-slavery men.
This divergence among his own supporters added another to the complications which beset Lincoln and taxed him to the utmost. He had extraordinary tact and shrewdness in managing men, and in dealing with tangled situations. He showed this power toward his Cabinet officers, who included the most various material,--Seward, accomplished, resourceful, somewhat superficial, but thoroughly loyal to his chief after he knew him, managing the foreign relations with admirable skill, and somewhat conservative in his views; Chase, very able as a financier and jurist, but intensely ambitious of the Presidency, regarded as a radical as to slavery; Stanton, a great war minister but of harsh and intractable temper. These men and their colleagues Lincoln handled so skilfully as to get the best each had to contribute, and keep them and the political elements they represented in working harmony. No less successfully did he deal with Congress, guiding it to a great extent, but acquiescing in occasional defeats and disappointments so patiently that he disarmed hostility. He kept in closest touch with the common people; he was accessible to every one, listened to each man's grievance, remonstrance, or advice; and acquired an instinctive knowledge of what was in the hearts and minds of the millions.
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.
