When this news reached him, Porter at once ordered his fastest boats to hasten to Alexandria. The advance of the fleet arrived off the town on the 15th of March, just as the last of the Confederate boats were making good their escape above the falls. Kilby Smith and his division followed on the transports with the remainder of the fleet, and, landing at Alexandria during the afternoon of the 16th, relieved the naval detachment sent ashore some hours earlier to occupy the town. On the 18th of March, A. J. Smith marched in with Mower's two divisions. Thus the advance of Porter's fleet was in Alexandria two days, and the head of A. J. Smith's column one day, ahead of the appointed time. Walker retreated on Natchitoches, accompanied by Gray's brigade of Mouton's division from the Huffpower. Taylor, quitting his headquarters at Alexandria, called in Polignac's brigade from the line of the Tensas and concentrated his force at Carroll Jones's plantation, on the road between Opelousas and Fort Jesup, distant forty-six miles in a south-southeasterly direction from Natchitoches, twelve miles south from Cotile, and twenty miles southwesterly from Alexandria. Here he was in a good position for receiving supplies and reinforcements, for covering Natchitoches, and for observing any approach of the Union forces either from Opelousas or from Alexandria. Meanwhile Banks had called in from Texas the divisions of Cameron and Ransom of the Thirteenth Corps and sent them to join Franklin on the lower Teche. The command of this detachment being given to Ransom, his division fell to Landram. Lee's cavalry was given the same direction, excepting Fonda's brigade, which stayed at Port Hudson. His last brigade, that of Dudley, marched from Donaldsonville on the 6th of March, crossed Berwick Bay on the 9th, and arrived at the cavalry camp near Franklin on the 10th. Cameron's wagons reached him at Berwick on the 12th, and he marched to join the army in the field on the morning of the 13th. On the evening of the same day Lee led the advance of the army from the town of Franklin, but, his column being quite nine miles long, it was not until the following morning that his rear-guard filed into the road. On the morning of the 15th of March he was followed by Emory and Ransom. Lee arrived at Alexandria on the 19th, Emory on the 25th, and Ransom on the 26th. The troops were, with some exceptions among the newly mounted regiments, in admirable condition, all were in fine spirits, and the long march of one hundred and sixty miles was well ordered and well executed, without confusion, haste, or delay, so that when, with closed ranks and bands playing, and with measured tread and all intervals observed, the column entered Alexandria, the appearance of the men drew exclamations of admiration even from critics the least friendly.
