In Hood's hasty evacuation of Atlanta many of his guns were left behind. These 12-pounder Napoleon bronze field-pieces have been gathered by the Federals from the abandoned fortifications, which had been equipped entirely with field artillery, such as these. It was an extremely useful capture for Sherman's army, whose supply of artillery had been somewhat limited during the siege, and still further reduced by the necessity to fortify Atlanta. On the march to the sea Sherman took with him only sixty-five field-pieces. The Negro refugees in the lower picture recall an embarrassment of the march to the sea. "Negroes of all sizes" flocked in the army's path and stayed there, a picturesque procession, holding tightly to the skirts of the army which they believed had come for the sole purpose of setting them free. The cavalcade of Negroes soon became so numerous that Sherman became anxious for his army's sustenance, and finding an old gray-haired black at Covington, Sherman explained to him carefully that if the Negroes continued to swarm after the army it would fail in its purpose and they would not get their freedom. Sherman believed that the old man spread this news to the slaves along the line of march, and in part saved the army from being overwhelmed by the contrabands.

CO.] [Illustration: THE DEFENDER OF SAVANNAH] The task of General Hardee in defending Savannah was one of peculiar difficulty. He had only eighteen thousand men, and he was uncertain where Sherman would strike. Some supposed that Sherman would move at once upon Charleston, but Hardee argued that the Union army would have to establish a new base of supplies on the seacoast before attempting to cross the numerous deep rivers and swamps of South Carolina. Hardee's task therefore was to hold Savannah just as long as possible, and then to withdraw northward to unite with the troops which General Bragg was assembling, and with the detachments scattered at this time over the Carolinas. In protecting his position around Savannah, Fort McAllister was of prime importance, since it commanded the Great Ogeechee River in such a way as to prevent the approach of the Federal fleet, Sherman's dependence for supplies. It was accordingly manned by a force of two hundred under command of Major G. W. Anderson, provided with fifty days' rations for use in case the work became isolated. This contingency did not arrive. About noon of December 13th, Major Anderson's men saw troops in blue moving about in the woods. The number increased. The artillery on the land side of the fort was turned upon them as they advanced from one position to another, and sharpshooters picked off some of their officers. At half-past four o'clock, however, the long-expected charge was made from three different directions, so that the defenders, too few in number to hold the whole line, were soon overpowered. Hardee now had to consider more
