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.
