The capture of Fort Henry was as inspiring to the national troops as it was discouraging to the rebels. General Grant telegraphed to Halleck that he had taken Fort Henry, and he announced his intention to serve Fort Donelson in the same way. Not a word had been said before about the strong work on the Cumberland, and Grant had no instructions from his superior on this point. Halleck made no reply to his despatch, though he notified General Buell of the expected attack. The idea of capturing Donelson was Grant's from its inception to its culmination in the surrender. He had no definite information in regard to the fort, but he formed his plan, not only to attack but to capture it. It seems to have been written down in his mind from the commencement that there was to be no failure. The flood and the continued heavy rains delayed the movement, and the troops were obliged to fight with the waters to save their scanty supplies. General Halleck used every exertion to supply Grant with troops and material, but he did not order the movement, or even express any hopes or opinions in regard to it. He simply suffered it to proceed, yielding all the assistance required of him; but it would have been curious to know what he would have said if the enterprise had proved to be a failure. Halleck sent minute orders in regard to the disposition of Fort Henry, instructing Grant to hold it, intimating that he would send picks and shovels to strengthen the work, and directed that the guns should be changed so as to meet an attack from the land; but he does not mention Donelson. He repeats his instructions very carefully on the 10th of the month, again kindly offers to send the picks and shovels, and assures the rising hero that large reënforcements would soon join him; but he is thoroughly non-committal on the subject of Fort Donelson. For my own part, I am thankful that he was so; for I am convinced that any man with a genius for war inferior to that of the illustrious soldier would have been a marplot if he had meddled with the matter. Grant was willing to take the responsibility; and doubtless the singular silence of his superior suggested to him his fate in case of failure. Grant did not wait for any of the additional force promised; and while the solemn autocrat in St. Louis was prating about picks and shovels, and matters which a volunteer who had seen service for a week understood as well as he, the bold brigadier in command hurried up Commodore Foote, who was waiting for the gunboats he had sent up the river. He was impatient to be on the move, and chafed like a leashed tiger at the delay; for the news kept coming in that the rebels were continually strengthening Donelson.
