I immediately ordered General Blair forward to Iuka, with the First Division, and, as fast as I got troops up, pushed them forward of Bear Creek, the bridge of which was completely destroyed, and an engineer regiment, under command of Colonel Flag, was engaged in its repairs.

Quite a considerable force of the enemy was assembled in our front, near Tuscumbia, to resist our advance.  It was commanded by General Stephen D. Lee, and composed of Roddy’s and Ferguson’s brigades, with irregular cavalry, amounting in the aggregate to about five thousand.

In person I moved from Corinth to Burnsville on the 18th, and to Iuka on the 19th of October.

Osterhaus’s division was in the advance, constantly skirmishing with the enemy; he was supported by General Morgan L. Smith’s, both divisions under the general command of Major-General Blair.  General John E. Smith’s division covered the working-party engaged in rebuilding the railroad.

Foreseeing difficulty in crossing the Tennessee River, I had written to Admiral Porter, at Cairo, asking him to watch the Tennessee and send up some gunboats the moment the stage of water admitted; and had also requested General Allen, quartermaster at St. Louis, to dispatch to Eastport a steam ferry-boat.

The admiral, ever prompt and ready to assist us, had two fine gunboats at Eastport, under Captain Phelps, the very day after my arrival at Iuka; and Captain Phelps had a coal-barge decked over, with which to cross our horses and wagons before the arrival of the ferry-boat.

Still following literally the instructions of General Halleck, I pushed forward the repairs of the railroad, and ordered General Blair, with the two leading divisions, to drive the enemy beyond Tuscumbia.  This he did successfully, after a pretty severe fight at Cane Creek, occupying Tuscumbia on the 27th of October.

In the meantime many important changes in command had occurred, which I must note here, to a proper understanding of the case.

General Grant had been called from Vicksburg, and sent to Chattanooga to command the military division of the Mississippi, composed of the three Departments of the Ohio, Cumberland, and Tennessee; and the Department of the Tennessee had been devolved on me, with instructions, however, to retain command of the army in the field.  At Iuka I made what appeared to me the best disposition of matters relating to the department, giving General McPherson full powers in Mississippi and General Hurlbut in West Tennessee, and assigned General Blair to the command of the Fifteenth Army Corps; and summoned General Hurlbut from Memphis, and General Dodge from Corinth, and selected out of the Sixteenth Corps a force of about eight thousand men, which I directed General Dodge to organize with all expedition, and with it to follow me eastward.
