Early in the year 1863 several changes were made in the Army of the Cumberland, and one of these was to transfer Fort Henry and Fort Donelson from Grant to Rosecrans, giving the latter the entire control of the Cumberland River. In the meantime, and during the several months to follow, the cavalry of the Union forces was recruited as much as possible, and many companies of infantry were placed on horseback, for Rosecrans had discovered that little or nothing could be done against the enemy's raiders by foot soldiers, no matter how daring or long-winded on the double-quick the latter might be. Toward the end of January, General Bragg, somewhat recovered from the shock of the conflict at Murfreesboro, thought it about time to make another demonstration against the army of the North, and he accordingly directed General Wheeler to make an attack against Fort Donelson, so gallantly taken by the forces under Grant nearly a year previous. Wheeler directed Forrest to move his brigade with a battery of four guns along the river road to the neighborhood of Dover, while he with Wharton's command took a road to the left. Several trusted scouts reported this movement to Rosecrans without delay, and the general immediately ordered Davis to take his division and two brigades of cavalry under Colonel Minty down the Versailles road and endeavor to take Wheeler in the rear, while Steedman was directed to watch the Confederate general's movements by way of Triune. As the work of the Riverlawn Cavalry was well known, Colonel Lyon was pressed into the services of the cavalry moving toward Fort Donelson without, however, Captain Batterson's battery being attached, as heretofore. The brigades of cavalry were directed to move by way of the Unionville and Rover roads, the infantry going direct to Eaglesville. The major and the captain arrived in camp just as the men were striking their tents. They were warmly received by Major Belthorpe, who wanted to know the news from home, and by Captain Gadbury, who was likewise anxious to hear from Lyndhall and especially from Margie. Both young men, however, lost no time in reporting to their father. "It's a bad business, Dexter," said the colonel, when the loss of the secret letter was alluded to. "I must say I am treed, as the bear said to Davy Crockett." "Don't you think the letter referred to the slaves, father?" said the major. "I always thought it did." "I did think so, because I was particularly cautioned by Brother Duncan not to dispose of any of the slaves under any circumstances. They originally numbered fifty-one, but three have died, leaving forty-eight, as perhaps you know." "Perhaps they were to be given their freedom," said Artie. "If that is so, President Lincoln's proclamation has forestalled Uncle Duncan's design."
