General Sterling Price, hitherto operating in Arkansas and Missouri, immediately after Shiloh, had been transferred with his army to Corinth to reinforce Beauregard, and when Bragg, who succeeded Beauregard, decided upon his plan of invasion, and had concentrated the bulk of his army at Chattanooga for that purpose, he assigned General Earl Van Dorn to the District of Mississippi and Price to the District of Tennessee, the latter to hold the line of the Mobile and Ohio Railroad, and both were to confront and watch Grant and prevent him from sending reinforcements to Buell. Price was left at Tupelo, Mississippi, with about 15,000 men. Later, September 11th, President Davis ordered Van Dorn to assume command of both his own and Price's army, the latter then on its march to Iuka, Mississippi, intending to move thence into Middle Tennessee if it should be found, as Bragg was led to believe, that Rosecrans (who, June 11th, had succeeded Pope in command of the Army of the Mississippi) had gone with his army to Nashville to reinforce Buell. Two of Grant's divisions, Paine's and Jeff C. Davis', had gone there, leaving the force for the defence of North Mississippi much reduced. Price entered Iuka September 14th, the garrison retiring without an engagement. Price, on learning that Rosecrans had retired on Corinth, telegraphed Van Dorn that he would turn back and co-operate in an attack on Corinth. Bragg telegraphed him to hasten towards Nashville. Rosecrans wired Grant to "watch the old wood-pecker or he would get away from them." September 17th, Halleck telegraphed Grant to prevent Price from crossing the Tennessee and forming a junction with Bragg. Grant telegraphed he would "do everything in his power to prevent such a catastrophe," and he began concentrating his troops against Price at Iuka. General E. O. C. Ord was moved to Burnsville, where Grant established his headquarters, and Rosecrans marched his two divisions to Jacinto, with orders to move on Iuka, flank Price, and cut off his retreat. General Stephen A. Hurlburt was ordered to make a strong demonstration from Bolivar, Tennessee, against Van Dorn, then near Grand Junction with about 10,000 effective men, and lead him to believe he was in immediate danger of an attack, and thus prevent him from making a diversion in aid of Price by marching on Corinth. This ruse was successful. Orders were given by Grant and preparation was made by Ord to attack Price at Iuka as soon as Rosecrans' guns on the Jacinto road were heard. About 4 P.M., September 19th, C. S. Hamilton's division, under Rosecrans, attacked Little's division of Price's army on the Jacinto road, and a severe combat ensued until night, with varying success, both sides at dark claiming a victory. Neither Grant nor Ord heard the sound of the battle in consequence of the intervening dense woods and an unfavorable wind. Rosecrans did not or could not advise Grant of the state of affairs,
