peculiar energy and military skill。 General Bragg had reorganized the army of Beauregard at Tupelo； carried it rapidly and skillfully toward Chattanooga； whence he boldly assumed the offensive； moving straight for Nashville and Louisville； and compelling General Buell to fall back to the Ohio River at Louisville。
The army of Van Dorn and Price had been brought from the trans…Mississippi Department to the east of the river； and was collected at and about Holly Springs； where； reenforced by Armstrong's and Forrests cavalry； it amounted to about forty thousand brave and hardy soldiers。 These were General Grant's immediate antagonists； and so many and large detachments had been drawn from him； that for a time he was put on the defensive。 In person he had his headquarters at Corinth； with the three divisions of Hamilton； Davies； and McKean； under the immediate orders of General Rosecrans。 General Ord had succeeded to the division of McClernand （who had also gone to Washington）； and held Bolivar and Grand Junction。 I had in Memphis my own and Hurlbut's divisions； and other smaller detachments were strung along the Memphis & Charleston road。 But the enemy's detachments could strike this road at so many points； that no use could be made of it； and General Grant had to employ the railroads； from Columbus； Kentucky； to Corinth and Grand Junction； by way of Jackson； Tennessee； a point common to both roads； and held in some force。
In the early part of September the enemy in our front manifested great activity； feeling with cavalry at all points； and on the 13th General Van Dorn threatened Corinth； while General Price seized the town of Iuka； which was promptly abandoned by a small garrison under Colonel Murphy。 Price's force was about eight thousand men； arid the general impression was that he was en route for Eastport； with the purpose to cross the Tennessee River in the direction of Nashville； in aid of General Bragg； then in full career for Kentucky。 General Grant determined to attack him in force； prepared to regain Corinth before Van Dorn could reach it。 He had drawn Ord to Corinth； and moved him； by Burnsville； on Iuka； by the main road； twenty…six miles。 General Grant accompanied this column as far as Burnsville。 At the same time he had dispatched Rosecrans by roads to the south； via Jacinto； with orders to approach Iuka by the two main roads； coming into Iuka from the south； viz。； they Jacinto and Fulton roads。
On the 18th General Ord encountered the enemy about four miles out of Iuka。 His orders contemplated that he should not make a serious attack； until Rosecrans had gained his position on the south； but； as usual； Rosecrans had encountered difficulties in the confusion of roads； his head of column did not reach the vicinity of Iuka till 4 p。m。 of the 19th； and then his troops were long drawn out on the single Jacinto road； leaving the Fulton road clear for Price's use。 Price perceived his advantage； and attacked with vehemence the head of Rosecrans's column； Hamilton's division； beating it back； capturing a battery； and killing and disabling seven hundred and thirty…six men； so that when night closed in Rosecrans was driven to the defensive； and Price； perceiving his danger； deliberately withdrew by the Fulton road； and the next morning was gone。 Although General Ord must have been within four or six miles of this battle； he did not hear a sound； and he or General Grant did not know of it till advised the next morning by a courier who had made a wide circuit to reach them。 General Grant was much offended with General Rosecrans because of this affair； but in my experience these concerted movements generally fail； unless with the very best kind of troops； and then in a country on whose roads some reliance can be placed； which is not the case in Northern Mississippi。 If Price was aiming for Tennessee； he failed； and was therefore beaten。 He made a wide circuit by the south； and again joined Van Dorn。
On the 6th of September； at Memphis； I received an order from General Grant dated the 2d； to send Hurlbut's division to Brownsville； in the direction of Bolivar； thence to report by letter to him at Jackson。 The division started the same day； and； as our men and officers had been together side by side from the first landing at Shiloh； we felt the parting like the breaking up of a family。 But General Grant was forced to use every man； for he knew well that Van Dorn could attack him at pleasure； at any point of his long line。 To be the better prepared； on the 23d of September he took post himself at Jackson； Tennessee； with a small reserve force； and gave Rosecrans command of Corinth； with his three divisions and some detachments； aggregating about twenty thousand men。 He posted General Ord with his own and Hurlbut'a divisions at Bolivar； with outposts toward Grand Junction and Lagrange。 These amounted to nine or ten thousand men； and I held Memphis with my own division； amounting to about six thousand men。 The whole of General Grant's men at that time may have aggregated fifty thousand； but he had to defend a frontage of a hundred and fifty miles； guard some two hundred miles of railway； and as much river。 Van Dom had forty thousand men； united； at perfect liberty to move in any direction； and to choose his own point of attack； under cover of woods； and a superior body of cavalry； familiar with every foot of the ground。 Therefore General Grant had good reason for telegraphing to General Halleck； on the 1st of October； that his position was precarious； 〃but I hope to get out of it all right。〃 In Memphis my business was to hold fast that important flank； and by that date Fort Dickering had been made very strong； and capable of perfect defense by a single brigade。 I therefore endeavored by excursions to threaten Van Dorn's detachments to the southeast and east。 I repeatedly sent out strong detachments toward Holly Springs； which was his main depot of supply； and General Grierson； with his Sixth Illinois； the only cavalry I had； made some bold and successful dashes at the Coldwater； compelling Van Dorn to cover it by Armstrong's whole division of cavalry。 Still； by the 1st of October； General Grant was satisfied that the enemy was meditating an attack in force on Bolivar or Corinth； and on the 2d Van Dorn made his appearance near Corinth； with his entire army。 On the 3d he moved down on that place from the north and northwest； General Roseerana went out some four miles to meet him； but was worsted and compelled to fall back within the line of his forts。 These had been began under General Halleck； but were much strengthened by General Grant； and consisted of several detached redoubts； bearing on each other； and inclosing the town and the depots of stores at the intersection of the two railroads。 Van Dorn closed down on the forts by the evening of the 3d； and on the morning of the 4th assaulted with great vehemence。 Our men； covered by good parapets； fought gallantly； and defended their posts well； inflicting terrible losses on the enemy； so that by noon the rebels were repulsed at all points； and drew off； leaving their dead and wounded in our hands。 Their losses； were variously estimated； but the whole truth will probably never be known； for in that army reports and returns were not the fashion。 General Rosecrans admitted his own loss to be three hundred and fifteen killed； eighteen hundred and twelve wounded； and two hundred and thirty…two missing or prisoners； and claimed on the part of the rebels fourteen hundred and twenty…three dead； two thousand and twenty…five prisoners and wounded。 Of course； most of the wounded must have gone off or been carried off； so that； beyond doubt； the rebel army lost at Corinth fully six thousand men。
Meantime； General Grant； at Jackson； had dispatched Brigadier… General McPherson； with a brigade； directly for Corinth； which reached General Rosecrans after the battle； and； in anticipation of his victory； had ordered him to pursue instantly； notifying him that he had ordered Ord's and Hurlbut's divisions rapidly across to Pocahontas； so as to strike the rebels in flank。 On the morning of the 5th； General Ord reached the Hatchie River； at Davies bridge； with four thousand men； crossed over and encountered the retreating army； captured a battery and several hundred prisoners； dispersing the rebel advance； and forcing the main column to make a wide circuit by the south in order to cross the Hatchie River。 Had General Rosecrans pursued promptly； and been on the heels of this mass of confused and routed men； Van Dorn's army would surely have been utterly ruined； as it was； Van Dom regained Holly Springs somewhat demoralized。
General Rosecrans did not begin his pursuit till the next morning； the 5th； and it was then too late。 General Grant was again displeased with him； and never became fully reconciled。 General Rosecrans was soon after relieved； and transferred to the Army of the Cumberland； in Tennessee； of which he afterward obtained the command； in place of General Buell； who was removed。
The effect of the battle of Corinth was very great。 It was； indeed； a decisive blow to the Confederate cause in our quarter； and changed the whole aspect of affairs in West T
