One shot struck the gunboat _Essex_, piercing her boilers, and wounding and scalding twenty-eight men. But at last, enveloped on all sides, his retreat cut off--the troops who had been ordered to depart in the morning, some three thousand in number, had reached Fort Donelson, twelve miles away--General Tilghman hauled down his flag, surrendering himself and eighty-four men as prisoners of war. Here we see him--a brave figure of a man--clad in the uniform of a Southern Colonel. There was never the slightest doubt of his courage or of his proper discretion in making this surrender. Only for a short time was he held a prisoner, when he was exchanged and welcomed back with all honor into the ranks of the Confederacy, and given an important command. He did not, however, live long to serve his cause, for shortly after rejoining the army he was killed at the battle of Baker's Creek, Mississippi, on the 16th of May, 1863. It is not often that on the battlefield ties of friendship are cemented that last a lifetime, and especially is this so between conqueror and conquered. Fort Donelson, that was, in a measure, a repetition of Fort Henry, saw two fighting foes become thus united. It was impossible for the garrison of Fort Donelson to make its escape after the flotilla of gunboats had once appeared in the river, although General Floyd, its senior commander, the former Secretary of War under President Buchanan, had withdrawn himself from the scene tendering the command to General Pillow, who in his turn, after escaping with his own brigade, left the desperate situation to be coped with by General Buckner. Assailed in the rear by an army that outnumbered the defenders of the fort by nearly eight thousand and with the formidable gunboats hammering his entrenchments from the river, Buckner decided to cut his way out in a desperate charge, but being repulsed, saw his men flung back once more into the fort. There was nothing for it but to make terms. On February 16th, in a note to Grant he asked what might be granted him. Here, the coming leader won his nickname of "Unconditional Surrender" Grant. Buckner was informed that the Federal army was about to move upon his works. Hurt and smarting under his position, he sent back a reply that in a few short hours he would, perhaps, have been willing to recall. Yielding to circumstances he accepted what he bluntly pronounced, "ungenerous and unchivalrous terms." But when the capitulation had taken place and nearly fifteen thousand men had surrendered, a greater number than ever before laid down their arms upon the continent, Grant was so generous, that then and there began the friendship that grew as close as if the two men were brothers of the blood. Most of the prisoners were paroled. Each one was allowed to retain his personal baggage, and the officers to keep their side arms. Grant had known Buckner in the Mexican War, and received him after the battle as his guest.
