General Parke and General Granger had ridden over from Strawberry Plains and reached Dandridge in the afternoon. Hearing of the presence of what was reported to be the whole of Longstreet's army, and not liking to accept battle with superior forces with the river at his back, Parke had caused an examination of the river to be made, and learned that just below the town was a shallow, fordable at an ordinary stage of water, and now about waist-deep for the men. In the low physical condition of our troops and their lack of clothing he very wisely thought it would not do to make them march through the river, but devised a foot-bridge by putting army wagons end to end and making a path over the boxes of the wagons. Sheridan was ordered to detach a brigade immediately to make this bridge, and it set to work at once. The plan was to march the infantry to the south side of the river and afterward remove the wagons, covering the operation by the cavalry who could then ford the stream, which though very cold and running with ice was not impracticable for horsemen. About dusk, as the skirmishing in front ceased, Sheridan and myself, with Sturgis, the commandant of the cavalry, were called to meet Generals Parke and Granger at a house in the town to report the condition of affairs in our front and to receive orders for marching. The bridge had been completed, as was supposed, and the brigade which had made it had been ordered across, when, on reaching the land on the left bank, they found, to their amazement, that they were upon an island with an equally deep and wide channel beyond! This news had just been received when we assembled at headquarters. Sheridan was greatly mortified at the blunder, but there was then no help for it. [Footnote: Official Records, vol. xxxii. pt. i. p. 79.] It was impracticable to complete the bridge before morning, and it was doubtful if wagons enough could be got together. My own command was on the extreme left of the line, partly covering the road back to Strawberry Plains, and we had not been engaged. The fighting had been in front of the centre and right. I could therefore throw no light on the question of the enemy's force. The information from other parts of the line and from prisoners left no doubt that infantry had engaged in the attack late in the afternoon and that Longstreet was present in force. There was therefore no dissent from the conclusion that it would be unwise to accept a battle with the river behind us, and orders were given to leave the position in the night and retire to Strawberry Plains. The wagons and most of the artillery were to follow the advance-guard, which was Sheridan's division, my command to march next, and Willich's (Wood's) division of the Fourth Corps to be the rear-guard. The cavalry were to march on a road a little to the right, leading to New Market, and would thus cover our flank.
