The casualties in Grant's army were 22 officers and 478 enlisted men killed, and 87 officers and 2021 men wounded, total 2608.(22) The loss in the navy under Foote was 10 killed and 44 wounded. The Confederate killed and wounded probably did not exceed 1500,(23) as they fought, in most part, behind intrenchments. The capture of Fort Donelson was thus far the greatest achievement of the war, and won for Grant just renown.
The writer's regiment, as we have stated, went into camp in December, 1861, at Bacon Creek, Kentucky. The winter was rainy and severe, the camps were much of the time muddy, and the troops underwent many hardships. It was their first winter in tents, and many were sick.
Colonel Marrow, on one pretence or another, was generally absent at Louisville, and the responsibility of the drill and discipline of the regiment devolved on Lieutenant-Colonel Beatty, who was quite equal to it, notwithstanding Marrow said and did much to prejudice the regiment against him. The writer also had the Colonel's displeasure.
On his return to the regiment, January 28th, Beatty handed him, to be forwarded, charges relating to his disloyalty, unmilitary conduct, and inefficiency; whereupon he decided to resign and the charges were withdrawn. Beatty became Colonel and I Lieutenant-Colonel, February 12, 1862.
Buell's army commenced to move southward February 10th, Mitchel's division in the advance.
The high railroad bridge over Green River at Munfordville had no railing or protection on the sides, but it was safely passed over with the teams by moonlight. The scene of the crossing was highly picturesque, and attracted much attention from the troops just starting on a new campaign.
The march of the 14th developed much of interest. There were evident signs of loyalty at the houses of all who owned no slaves, and where slaves appeared they exhibited the greatest delight to see the Union soldiers. All slaves had the belief that we had come to free them, and there was much difficulty in preventing them from marching with us. The country through which we passed was cavernous, and the surface had many bowl-like depressions, at the bottom of which was, generally, considerable water. Springs and streams were scarce. The Confederates on retiring drove their disabled, diseased and broken-down horses, mules, etc., into these ponds and shot them, leaving them to decay and thus render the water unfit for use by the Union Army.(24) The troops had no choice but to use the water from the befouled ponds. We shall hear of them again.
On this day the division reached Barren River and exchanged a few artillery shots with the rear of General A. S. Johnston's army, under the immediate command of General Hardee. The next day—the last day of fighting at Fort Donelson—the advance of Mitchel's division crossed the river and occupied Bowling Green, which was found strongly fortified and a naturally good position for defence. In its hasty evacuation many stores were burned; others distributed to the inhabitants, and some abandoned to capture. After an unaccountable delay here of one week, during which time we heard of the victory at Fort Donelson, Mitchel's division, still in advance, resumed its march towards Nashville, distant about seventy miles. The head of the division reached Edgefield (suburb of Nashville on the north bank of the Cumberland) on the evening of the 24th of February, and the following morning the Mayor and a committee of citizens formally surrendered the city of Nashville while yet Forrest's cavalry occupied it. General Nelson's division of Buell's army arrived by boats the night of the 24th, and at once landed in the city.
Nashville would have been a rich prize and easily taken if troops from either Donelson or Bowling Green had been pushed forward without delay when Fort Donelson fell.
General A. S. Johnston abandoned the city as early as the 16th, and concentrated his forces at Murfreesboro, thirty or more miles distant, leaving only Floyd with a demoralized brigade and Colonel N. B. Forrest's small cavalry command to remove or destroy the guns and stores, of which there was an immense quantity.
