As a result of this expedition General Smith reported that he thought it practicable to capture Fort Heiman. This fort stood on high ground, completely commanding Fort Henry on the opposite side of the river, and its possession by us, with the aid of our gunboats, would insure the capture of Fort Henry. This report of Smith's confirmed views I had previously held, that the true line of operations for us was up the Tennessee and Cumberland rivers. With us there, the enemy would be compelled to fall back on the east and west entirely out of the State of Kentucky. On the 6th of January, before receiving orders for this expedition, I had asked permission of the general commanding the department to go to see him at St. Louis. My object was to lay this plan of campaign before him. Now that my views had been confirmed by so able a general as Smith, I renewed my request to go to St. Louis on what I deemed important military business. The leave was granted, but not graciously. I had known General Halleck but very slightly in the old army, not having met him either at West Point or during the Mexican war. I was received with so little cordiality that I perhaps stated the object of my visit with less clearness than I might have done, and I had not uttered many sentences before I was cut short as if my plan was preposterous. I returned to Cairo very much crestfallen.
Flag-officer Foote commanded the little fleet of gunboats then in the neighborhood of Cairo and, though in another branch of the service, was subject to the command of General Halleck. He and I consulted freely upon military matters and he agreed with me perfectly as to the feasibility of the campaign up the Tennessee. Notwithstanding the rebuff I had received from my immediate chief, I therefore, on the 28th of January, renewed the suggestion by telegraph that "if permitted, I could take and hold Fort Henry on the Tennessee." This time I was backed by Flag-officer Foote, who sent a similar dispatch. On the 29th I wrote fully in support of the proposition. On the 1st of February I received full instructions from department headquarters to move upon Fort Henry. On the 2d the expedition started.
In February, 1862, there were quite a good many steamers laid up at Cairo for want of employment, the Mississippi River being closed against navigation below that point. There were also many men in the town whose occupation had been following the river in various capacities, from captain down to deck hand But there were not enough of either boats or men to move at one time the 17,000 men I proposed to take with me up the Tennessee. I loaded the boats with more than half the force, however, and sent General McClernand in command. I followed with one of the later boats and found McClernand had stopped, very properly, nine miles below Fort Henry. Seven gunboats under Flag-officer Foote had accompanied the advance. The transports we had with us had to return to Paducah to bring up a division from there, with General C. F. Smith in command.
