The main course of the war in the West having now drifted away from the Mississippi Valley to the region south and southeast of Nashville, embracing Southern and Eastern Tennessee and the northern parts of Georgia, Alabama, and Mississippi, the convoy and gunboat service on the Tennessee and Cumberland assumed new importance. An eleventh division was formed on the upper waters of the Tennessee, above Muscle Shoals, under the command of Lieutenant Moreau Forrest; Lieutenant-Commander Shirk had the lower river, and Fitch still controlled the Cumberland. When Hood, after the fall of Atlanta, began his movement toward Tennessee in the latter part of October, General Forrest, the active Confederate cavalry leader, who had been stationed at Corinth with his outposts at Eastport and on the Tennessee River, moved north along the west bank, and with seventeen regiments of cavalry and nine pieces of artillery appeared on the 28th before Fort Heiman, an earthwork about seventy-five miles from Paducah. Here he captured two transports and a light-draught called the Undine. On the 2nd of November he had established batteries on the west bank both above and below Johnsonville, one of the Union army's bases of supplies and a railway terminus, thus blockading the water approach and isolating there eight transports, with barges, and three light-draughts, the Key West, Elfin, and Tawah. Nevertheless, the three boats went down and engaged the lower battery, and though they found it too strong for them they retook one of the transports. Meantime Shirk had telegraphed the Admiral and Fitch, and the latter came to his assistance with three of the Cumberland River light-draughts. Going on up the Tennessee Fitch picked up three other light-draughts, and on the morning of the 4th approached the lower battery from below, Lieutenant King, the senior officer above, coming down at the same time. The enemy then set fire to the Undine, but the channel was so narrow and intricate that Fitch did not feel justified in attempting to take his boats up, and King was not able to run by. Fitch, whose judgment and courage were well proved, said that the three blocked gunboats were fought desperately and well handled, but that they could not meet successfully the heavy rifled batteries then opposed to them in such a channel. All three were repeatedly struck and had several of their guns disabled. They then retired to the fort, where the enemy opened on them in the afternoon with a battery on the opposite shore. After firing away nearly all their ammunition, and being further disabled, Lieutenant King, fearing that they might fall into the enemy's hands, burnt them with the transports. The place was relieved by General Schofield twenty-four hours later, so that if King had patiently held on a little longer his pluck and skill would have been rewarded by saving his vessels. At about the same time, October 28th, General Granger being closely pressed in Decatur, Alabama, above
