opposition, not actually to the prosecution of the war, but to any and every measure essential for it, was now developing, and a serious division, such as at this stage any important resignation would have produced in the ranks of the Republicans, or, as they now called themselves, the "Union men," would have been perilous. On the first day of January, 1863, the President signed the further Proclamation needed to give effect to emancipation. The small portions of the South which were not in rebellion were duly excepted; the naval and military authorities were ordered to maintain the freedom of the slaves seeking their protection; the slaves were enjoined to abstain from violence and to "labour faithfully for reasonable wages" if opportunity were given them; all suitable slaves were to be taken into armed service, especially for garrison duties. Before the end of 1863, a hundred thousand coloured men were already serving, as combatants or as labourers, on military work in about equal number. They were needed, for volunteering was getting slack, and the work of guarding and repairing railway lines was specially repellent to Northern volunteers. The coloured regiments fought well; they behaved well in every way. Atrocious threats of vengeance on them and their white officers were officially uttered by Jefferson Davis, but, except for one hideous massacre wrought in the hottest of hot blood, only a few crimes by individuals were committed in execution of these threats. To Lincoln himself it was a stirring thought that when democratic government was finally vindicated and restored by the victory of the Union, "then there will be some black men who can remember that with silent tongue and clenched teeth and steady eye and well-poised bayonet they have helped mankind on to this great consummation." There was, however, prejudice at first among many Northern officers against negro enlistment. The greatest of the few great American artists, St. Gaudens, commemorated in sculpture (as the donor of the new playing fields at Harvard commemorated by his gift) the action of a brilliant and popular Massachusetts officer, Robert Gould Shaw, who set the example of leaving his own beloved regiment to take command of a coloured regiment, at the head of which he died, gallantly leading them and gallantly followed by them in a desperate fight.
