At this moment Donelson was held by eighteen thousand men under the command of General John B. Floyd, late Secretary of War in the cabinet of Buchanan. Next to him were Gideon J. Pillow and Simon B. Buckner. The Union army under Grant was divided into three parts under the respective commands of Charles F. Smith, a veteran of the regular army; John A. McClernand, an Illinois lawyer and member of Congress, and Lew Wallace, the future author of “Ben Hur.”
With waving banners the divisions of Smith and McClernand marched across country on February 12th, arriving at noon and encircling the doomed fort ere nightfall. Smith was stationed on the left and McClernand on the extreme right, near the village of Dover. This left an open space in the center, to be filled by Lew Wallace, who arrived with his division the next day. On the 13th there was a continuous bombardment from morning till night, punctuated by the sharp crack of the sharpshooter’s rifle.
The chief action of the day that involved the infantry was an attempt to capture a battery on a hill, near the center of the Confederate line of battle, known as Maney’s Battery, commanded by Captain Maney, of Tennessee. This battery had annoyed McClernand greatly, and he delegated his third brigade to capture it. The charge was led by Colonel Morrison of Illinois, and a braver one never was made throughout the whole period of the war. The men who made it were chiefly youths from the farms and workshops of Illinois. With no apparent thought of danger they sallied forth, determined at all hazards to capture the battery on the hill, which stood out in relief against the sky. As they ran up the hill, firing as they went, their numbers were rapidly thinned by the terrific cross-fire from this battery and two others on adjoining hills. Still the survivors pushed on and their deadly fire thinned the ranks of the men at the battery. At length when they came within forty yards of the goal a long line of Confederate musketry beside the battery suddenly burst into flame and a storm of bullets cut down the brave boys of Illinois, with fearful slaughter. Even then they stood for fifteen minutes, returning volley for volley, before retreating. Reaching the foot of the hill, they rallied under the Stars and Stripes, and returned to the assault. Even a third time they charged, but the dry leaves on the ground now caught fire, the smoke stifled them, and they had to retreat. As they returned down the hill, Lew Wallace tells us, “their ears and souls were riven with the shrieks of their wounded comrades, upon whom the flames crept and smothered and charred where they lay.”
Thus ended the 13th of February. That night the river gunboats, six in number, four of them ironclads, under the command of Andrew H. Foote, arrived. Grant had sent them down the Tennessee to the Ohio and up the Cumberland, to support his army at Fort Donelson. On the 14th, about three in the afternoon, Foote steamed with his four ironclads to a point in the river within four hundred yards of the two powerful batteries on the river bank under the fort and opened fire with his cannon while continuing to advance. The reply from the Confederate batteries was terrific and many of their shots struck home. In a short time the decks of the vessels were slippery with human blood. Foote himself was severely wounded. At length a solid shot struck the pilot house of the flagship and tore away the pilot wheel. At almost the same moment another gunboat was disabled. The two vessels, one of which had been struck fifty-nine times, could no longer be managed; they turned about with the eddies of the river and floated down with the current. The others followed.
The Confederates raised a wild shout of joy at this, their second victory since the coming of the Union army. But what will be the story of the morrow? With the reënforcements brought by Foote, Lew Wallace’s division, Grant’s army was now swelled to twenty-seven thousand, and in spite of the initial repulse the Federals felt confident of ultimate victory. But a dreary night was before them. The springlike weather had changed. All that fearful night of February 14th there was a fierce, pitiless wind with driving sleet and snow. Thousands of the men, weary of the burden of their overcoats and blankets during the warm preceding days, had thrown them away. Now they spent the night lying behind logs or in ditches or wherever they could find a little protection from the wintry blasts. General Floyd, knowing that Grant’s army was much stronger than his own, decided, after consulting with Pillow and Buckner, to attack the Union right at dawn on the 15th.
The night was spent in preparing for this, and in the morning Pillow with ten thousand men fell upon McClernand, and Buckner soon joined him with an additional force. Toward noon many of McClernand’s men ran short of powder and he was forced to recede from his position. Pillow seems then to have lost his head. He felt that the whole Union army was defeated, and though the road to Nashville was open, the Confederates made no attempt to escape. Just then General Grant rode upon the scene. He had been absent all morning down the river consulting Foote, not knowing that the Confederates had planned an escape. This moment, says Lew Wallace, was the crisis in the life of Grant.
Hearing the disastrous news, his face flushed for a moment; he crushed some papers in his hand. Next instant he was calm, and said in his ordinary tone, to McClernand and Wallace, “Gentlemen, the position on the right must be retaken.” Then he galloped away to General Smith. In a short time the Union lines were in motion. General Smith made a grand assault on the Confederate outworks and rifle-pits. When his lines hesitated Smith waved his cap on the point of his sword and rode in front, up the hill, in the hottest fire of the foe, toward the rifle-pits—and they were carried. At the same moment Lew Wallace was leading his division up another slope with equal gallantry. Here again the Confederates retired, and the road to Nashville was no longer open. Furthermore, Smith held a position from which he could shell the fort on the inside, and nothing was left to the inmates but surrender or slaughter on the morrow.
A council was held by Floyd, Pillow, and Buckner. Buckner, who was a master in the art of warfare, declared that he could not hold his position for half an hour in the morning. The situation was hopeless. Floyd was under indictment at Washington for maladministration in the Buchanan cabinet. He declared that he must not be taken, and that with his Virginia troops he would escape on two little boats that were to arrive from Nashville in the morning. He passed the command to Pillow, and Pillow, declaring that he too would escape, passed it on to Buckner. Floyd and Pillow with their men made good their escape; so did Colonel Forrest, the cavalry leader, and his mounted force.
In the early morning Buckner sent a note to Grant offering to capitulate. The answer is well known. Grant demanded “unconditional surrender,” and added, “I propose to move immediately on your works.” Buckner was too good a soldier to sacrifice his men in needless slaughter. His men were so worn with eighty-four hours of fighting and watching that many of them had fallen asleep while standing in battle-line and under fire. He accepted the “ungenerous and unchivalrous terms,” as he pronounced them, and surrendered Fort Donelson and the army, consisting of at least fourteen thousand men, with all its stores of ammunition. The Union loss was over twenty-eight hundred men. The Confederate loss, killed and wounded, was about two thousand.
The capture of Fort Donelson did three things. First, it opened up the way for the Federal army to penetrate the heart of the western South and gave it control of Kentucky and of western Tennessee. Second, it electrified the North with confident hopes of ultimate success. It was the first great victory for the North in the war. Bull Run had been a moral victory to the South, but the vanquished were weakened scarcely more than the victors. At Donelson, the victors gained control of an extensive territory and captured a noble army which could ill be spared by the South and which could not be replaced. Third, the capture of Donelson forced before the nation a new man—Ulysses S. Grant.
