He soon perceived that he was the only man between the Confederates and the boats. His horse seemed to realize the situation. Grant says: "There was no path down the bank, and every one acquainted with the Mississippi River knows that its banks, in a natural state, do not vary at any great angle from the perpendicular. My horse put his fore feet over the bank without hesitation or urging, and, with his hind feet well under him, slid down the bank and trotted aboard the boat, twelve or fifteen feet away, over a single gangplank. I dismounted and went at once to the upper deck.... When I first went on deck I entered the captain's room, adjoining the pilot-house, and threw myself on a sofa. I did not keep that position a moment, but rose to go out on the deck to observe what was going on. I had scarcely left when a musket-ball entered the room, struck the head of the sofa, passed through it, and lodged in the boat." Thus again was his life saved. Until February of the following year, 1862, little was done by the troops, except to become ready for the great work before them. The enemy occupied strong points on the Tennessee and Cumberland rivers, at Forts Henry and Donelson, points as essential to us as to them. These Grant determined to take, if possible. Truly said President Lincoln, "Wherever Grant is things move. I have noticed that from the beginning." On February 2 the expedition started against Fort Henry, with about seventeen thousand men. Several gun-boats, under Commodore Foote, accompanied the army. At a given hour the troops and gun-boats moved together, the one to invest the garrison, the other to attack the fort. After a severe fight of an hour and a half every gun was silenced. General Lloyd Tilghman surrendered, with his seventeen heavy guns, ammunition, and stores. Fort Donelson must now be taken, strongly fortified as it was. It stood on high ground, with rifle-pits running back two miles from the river, and was defended by fifteen heavy guns, two carronades, and sixty-five pieces of artillery. Outside the rifle-pits, trees had been felled, so that the tops lay toward the attacking army. Our men had no shelter from the snow and rain in this midwinter siege. No campfires could be allowed where the enemy could see them. In the march from Fort Henry to Fort Donelson numbers of the tired troops had thrown away their blankets and overcoats, and there was much real suffering. But war means discomfort and woe as well as death itself.
