Four days later, Lieutenant-Commander Le Roy Fitch, in active charge of the two rivers, was going up the Cumberland with a fleet of transports, convoyed by the Lexington and five light-draughts. When twenty-four miles below Dover, the town on the west bank near which Fort Donelson was situated, he met a steamer bearing a message from Colonel Harding, commanding the post, to the effect that his pickets had been driven in and that he was attacked in force. Fitch at once left the convoy and pushed ahead as fast as he could. A short distance below the town he met a second steamer with the news that Harding was surrounded. At 8 P.M. he arrived, and found the Union forces not only surrounded by overwhelming forces but out of ammunition. The enemy, not thinking about gunboats, had posted the main body of his troops in a graveyard at the west end of the town, the left wing resting in a ravine that led down to the river, thus enabling the vessels to rake that portion of his line. The gunboats opened fire simultaneously up the ravine, into the graveyard and upon the valley beyond. Taken wholly by surprise, the Confederates did not return a shot, but decamped in haste. Leaving two boats to maintain the fire through the ravine, Fitch hastened up with the other four to shell the main road, which, after leaving the upper end of the town, follows nearly the bank of the stream for some distance. The attacking force in this case was 4,500 strong, composed of regular Confederate troops under Generals Wheeler, Forrest, and Wharton. By 11 P.M. they had disappeared, leaving 140 dead. The garrison, which numbered only 800, had defended itself gallantly against this overwhelming force since noon, but was _in extremis_ when the gunboats arrived. On the 27th of March, Fitch was at Fort Hindman, on the Tennessee, where he took on board a force of 150 soldiers and went up the river. On reaching Savanna he heard of a cotton-mill four miles back being run for the Confederate army. The troops and a force of sailors were landed and took the mill, although a regiment of the enemy's cavalry was but two or three miles away. Finding no sure proof of its working for the army, they did not destroy the building, but removed some of the essential parts of the machinery. Going on to Chickasaw, south of the Tennessee line, as the water was too low for the Lexington, he sent on two light-draughts as far as Florence, where they shelled a camp of the enemy. The rapid falling of the river obliged them to return. On the way a quantity of food and live stock belonging to a noted abettor of guerilla warfare were seized.
