It must be noted also that it was not till the 24th that the troops at Decatur and Huntsville were ordered back, the withdrawal being made on the 25th. General R. S. Granger's old troops were then placed at Stevenson, and those recently recruited were sent to Murfreesborough. Granger reported that the public property, except some forage, had been removed; but by what seems to have been a misunderstanding with the naval officers about convoying transports, the pontoon bridge was only detached at its southern end, and was neither taken up stream nor destroyed. It swung with the current against the northern shore, and proved of great use to Hood in his retreat a month later. [Footnote: _Id_., pp. 1003, 1027, 1046. See also "Franklin and Nashville," p. 125.] The continued hope that A. J. Smith's corps would arrive in time to reach Pulaski or Columbia before we should have to retreat counted for much, no doubt, in Thomas's postponement of decisive action; but it can hardly be disputed that the true military course would have been to strip his garrisons to the bone immediately after Sherman marched southward, concentrate at Pulaski a force superior to Hood's, and give him battle if he dared to advance north from Florence. [Footnote: For the forces on both sides in Tennessee, see Official Records, vol. xlv. pt. i. pp. 52-54, 678-679; "Franklin and Nashville," pp. 132-136; "The Battle of Franklin," pp. 9, 208. I discussed the same subject in "The Nation" for Nov. 9, 1893, p. 352.] As it was too late for concentration at Duck River or south of it, Schofield was limited to a careful defensive, though he was willing to receive Hood's attack upon our lines. [Footnote: Official Records, vol. xlv. pt. i. p. 1017.] The latter, however, did no more than keep up a combat of skirmish lines, whilst he looked for ways to turn the position. Schofield, on his part, prepared a short interior line to be held by part of his troops when it was time to cross the river with the rest. In the night of the 25th this movement was made, and for a couple of days more our forces were divided, part holding the short line on the south side, and the greater portion encamped in the bend on the north bank, closely watching the development of the enemy's evident purpose to cross some miles above us.
