The designation of my command had been changed after Halleck's arrival, from the District of South-east Missouri to the District of Cairo, and the small district commanded by General C. F. Smith, embracing the mouths of the Tennessee and Cumberland rivers, had been added to my jurisdiction. Early in January, 1862, I was directed by General McClellan, through my department commander, to make a reconnoissance in favor of Brigadier-General Don Carlos Buell, who commanded the Department of the Ohio, with headquarters at Louisville, and who was confronting General S. B. Buckner with a larger Confederate force at Bowling Green. It was supposed that Buell was about to make some move against the enemy, and my demonstration was intended to prevent the sending of troops from Columbus, Fort Henry or Donelson to Buckner. I at once ordered General Smith to send a force up the west bank of the Tennessee to threaten forts Heiman and Henry; McClernand at the same time with a force of 6,000 men was sent out into west Kentucky, threatening Columbus with one column and the Tennessee River with another. I went with McClernand's command. The weather was very bad; snow and rain fell; the roads, never good in that section, were intolerable. We were out more than a week splashing through the mud, snow and rain, the men suffering very much. The object of the expedition was accomplished. The enemy did not send reinforcements to Bowling Green, and General George H. Thomas fought and won the battle of Mill Springs before we returned.
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.
Before sending the boats back I wanted to get the troops as near to the enemy as I could without coming within range of their guns. There was a stream emptying into the Tennessee on the east side, apparently at about long range distance below the fort. On account of the narrow water-shed separating the Tennessee and Cumberland rivers at that point, the stream must be insignificant at ordinary stages, but when we were there, in February, it was a torrent. It would facilitate the investment of Fort Henry materially if the troops could be landed south of that stream. To test whether this could be done I boarded the gunboat Essex and requested Captain Wm. Porter commanding it, to approach the fort to draw its fire. After we had gone some distance past the mouth of the stream we drew the fire of the fort, which fell much short of us. In consequence I had made up my mind to return and bring the troops to the upper side of the creek, when the enemy opened upon us with a rifled gun that sent shot far beyond us and beyond the stream. One shot passed very near where Captain Porter and I were standing, struck the deck near the stern, penetrated and passed through the cabin and so out into the river. We immediately turned back, and the troops were debarked below the mouth of the creek.
When the landing was completed I returned with the transports to Paducah to hasten up the balance of the troops. I got back on the 5th with the advance the remainder following as rapidly as the steamers could carry them. At ten o'clock at night, on the 5th, the whole command was not yet up. Being anxious to commence operations as soon as possible before the enemy could reinforce heavily, I issued my orders for an advance at 11 A.M. on the 6th. I felt sure that all the troops would be up by that time.
Fort Henry occupies a bend in the river which gave the guns in the water battery a direct fire down the stream. The camp outside the fort was intrenched, with rifle pits and outworks two miles back on the road to Donelson and Dover. The garrison of the fort and camp was about 2,800, with strong reinforcements from Donelson halted some miles out. There were seventeen heavy guns in the fort. The river was very high, the banks being overflowed except where the bluffs come to the water's edge. A portion of the ground on which Fort Henry stood was two feet deep in water. Below, the water extended into the woods several hundred yards back from the bank on the east side. On the west bank Fort Heiman stood on high ground, completely commanding Fort Henry. The distance from Fort Henry to Donelson is but eleven miles. The two positions were so important to the enemy, as he saw his interest, that it was natural to suppose that reinforcements would come from every quarter from which they could be got. Prompt action on our part was imperative.
The plan was for the troops and gunboats to start at the same moment. The troops were to invest the garrison and the gunboats to attack the fort at close quarters. General Smith was to land a brigade of his division on the west bank during the night of the 5th and get it in rear of Heiman.
At the hour designated the troops and gunboats started. General Smith found Fort Heiman had been evacuated before his men arrived. The gunboats soon engaged the water batteries at very close quarters, but the troops which were to invest Fort Henry were delayed for want of roads, as well as by the dense forest and the high water in what would in dry weather have been unimportant beds of streams. This delay made no difference in the result. On our first appearance Tilghman had sent his entire command, with the exception of about one hundred men left to man the guns in the fort, to the outworks on the road to Dover and Donelson, so as to have them out of range of the guns of our navy; and before any attack on the 6th he had ordered them to retreat on Donelson. He stated in his subsequent report that the defence was intended solely to give his troops time to make their escape.
Tilghman was captured with his staff and ninety men, as well as the armament of the fort, the ammunition and whatever stores were there. Our cavalry pursued the retreating column towards Donelson and picked up two guns and a few stragglers; but the enemy had so much the start, that the pursuing force did not get in sight of any except the stragglers.
All the gunboats engaged were hit many times. The damage, however, beyond what could be repaired by a small expenditure of money, was slight, except to the Essex. A shell
