The troops were not intrenched, but the nature of the ground was such that they were just as well protected from the fire of the enemy as if rifle-pits had been thrown up. Our line was generally along the crest of ridges. The artillery was protected by being sunk in the ground. The men who were not serving the guns were perfectly covered from fire on taking position a little back from the crest. The greatest suffering was from want of shelter. It was midwinter and during the siege we had rain and snow, thawing and freezing alternately. It would not do to allow camp-fires except far down the hill out of sight of the enemy, and it would not do to allow many of the troops to remain there at the same time. In the march over from Fort Henry numbers of the men had thrown away their blankets and overcoats. There was therefore much discomfort and absolute suffering.
During the 12th and 13th, and until the arrival of Wallace and Thayer on the 14th, the National forces, composed of but 15,000 men, without intrenchments, confronted an intrenched army of 21,000, without conflict further than what was brought on by ourselves. Only one gunboat had arrived. There was a little skirmishing each day, brought on by the movement of our troops in securing commanding positions; but there was no actual fighting during this time except once, on the 13th, in front of McClernand's command. That general had undertaken to capture a battery of the enemy which was annoying his men. Without orders or authority he sent three regiments to make the assault. The battery was in the main line of the enemy, which was defended by his whole army present. Of course the assault was a failure, and of course the loss on our side was great for the number of men engaged. In this assault Colonel William Morrison fell badly wounded. Up to this time the surgeons with the army had no difficulty in finding room in the houses near our line for all the sick and wounded; but now hospitals were overcrowded. Owing, however, to the energy and skill of the surgeons the suffering was not so great as it might have been. The hospital arrangements at Fort Donelson were as complete as it was possible to make them, considering the inclemency of the weather and the lack of tents, in a sparsely settled country where the houses were generally of but one or two rooms.
On the return of Captain Walke to Fort Henry on the 10th, I had requested him to take the vessels that had accompanied him on his expedition up the Tennessee, and get possession of the Cumberland as far up towards Donelson as possible. He started without delay, taking, however, only his own gunboat, the Carondelet, towed by the steamer Alps. Captain Walke arrived a few miles below Donelson on the 12th, a little after noon. About the time the advance of troops reached a point within gunshot of the fort on the land side, he engaged the water batteries at long range. On the 13th I informed him of my arrival the day before and of the establishment of most of our batteries, requesting him at the same time to attack again that day so that I might take advantage of any diversion. The attack was made and many shots fell within the fort, creating some consternation, as we now know. The investment on the land side was made as complete as the number of troops engaged would admit of.
During the night of the 13th Flag-officer Foote arrived with the iron-clads St. Louis, Louisville and Pittsburg and the wooden gunboats Tyler and Conestoga, convoying Thayer's brigade. On the morning of the 14th Thayer was landed. Wallace, whom I had ordered over from Fort Henry, also arrived about the same time. Up to this time he had been commanding a brigade belonging to the division of General C. F. Smith. These troops were now restored to the division they belonged to, and General Lew. Wallace was assigned to the command of a division composed of the brigade of Colonel Thayer and other reinforcements that arrived the same day. This new division was assigned to the centre, giving the two flanking divisions an opportunity to close up and form a stronger line.
The plan was for the troops to hold the enemy within his lines, while the gunboats should attack the water batteries at close quarters and silence his guns if possible. Some of the gunboats were to run the batteries, get above the fort and above the village of Dover. I had ordered a reconnoissance made with the view of getting troops to the river above Dover in case they should be needed there. That position attained by the gunboats it would have been but a question of time--and a very short time, too--when the garrison would have been compelled to surrender.
By three in the afternoon of the 14th Flag-officer Foote was ready, and advanced upon the water batteries with his entire fleet. After coming in range of the batteries of the enemy the advance was slow, but a constant fire was delivered from every gun that could be brought to bear upon the fort. I occupied a position on shore from which I could see the advancing navy. The leading boat got within a very short distance of the water battery, not further off I think than two hundred yards, and I soon saw one and then another of them dropping down the river, visibly disabled. Then the whole fleet followed and the engagement closed for the day. The gunboat which Flag-officer Foote was on, besides having been hit about sixty times, several of the shots passing through near the waterline, had a shot enter the pilot-house which killed the pilot, carried away the wheel and wounded the flag-officer himself. The tiller-ropes of another vessel were carried away and she, too, dropped helplessly back. Two others had their pilot-houses so injured that they scarcely formed a protection to the men at the wheel.
