But the splendid victory gained a short time before at Chattanooga had raised the blockade upon our line of supply, and the railroad to Chattanooga and Nashville was soon opened, so that our starving and naked troops could begin to get supplies of food and clothing. The movement of the first train of cars was reported by telegraph from every station, and was eagerly awaited by the entire army. When the locomotive whistle announced its approach, everybody turned out to welcome it with shouts of joy. It proved to consist of ten car-loads of horse and mule shoes for the dead animals which strewed the plains! Fortunately the disgust produced by this disappointment was not of long duration. The next train, which followed very soon, contained coffee, sugar, and other articles to gladden the hearts of hungry soldiers.
The Confederate army under Longstreet still remained in East Tennessee. A movement had recently been made by our troops, under the immediate command of General John G. Parke (General Foster being too lame to take the field in person), to drive Longstreet out. But the movement had failed, the troops returning to Knoxville with the loss of considerable material. In consequence of this, much anxiety was felt in Washington regarding the situation in East Tennessee. It was even apprehended that Knoxville might be in danger; and an advance of Longstreet's force to Strawberry Plains, where he laid a bridge over the Holston and crossed a part of his troops, seemed to give some ground for such apprehensions.
The miserable condition of our troops, the season of the year, the almost total lack of means of transportation for supplies and of a pontoon bridge to cross the river, rendered any considerable movement on our part impossible. But to relieve the existing apprehension, I determined to assume the offensive at once, and to maintain it as far as possible.
Early in February General Grant had proposed to give me 10,000 additional troops from General Thomas's army at Chattanooga, and to let me begin the campaign against Longstreet at once. But on February 16 he informed me that the movement would have to be delayed because of some operations in which General Thomas was to engage. Nevertheless, I advanced on the 24th with what force I had, at the same time sending a reconnaissance south of the French Broad River to ascertain the nature of a hostile movement reported in that direction.
