Major-General Canby, who had been assigned to the command of the "Military Division of the West Mississippi," was therefore directed to send the 19th army corps to join the armies operating against Richmond, and to limit the remainder of his command to such operations as might be necessary to hold the positions and lines of communications he then occupied. Before starting General A. J. Smith's troops back to Sherman, General Canby sent a part of it to disperse a force of the enemy that was collecting near the Mississippi River. General Smith met and defeated this force near Lake Chicot on the 5th of June. Our loss was about forty killed and seventy wounded. In the latter part of July, General Canby sent Major-General Gordon Granger, with such forces as he could collect, to co-operate with Admiral Farragut against the defences of Mobile Bay. On the 8th of August, Fort Gaines surrendered to the combined naval and land forces. Fort Powell was blown up and abandoned. On the 9th, Fort Morgan was invested, and, after a severe bombardment, surrendered on the 23d. The total captures amounted to one thousand four hundred and sixty-four prisoners, and one hundred and four pieces of artillery. About the last of August, it being reported that the rebel General Price, with a force of about ten thousand men, had reached Jacksonport, on his way to invade Missouri, General A. J. Smith's command, then en route from Memphis to join Sherman, was ordered to Missouri. A cavalry force was also, at the same time, sent from Memphis, under command of Colonel Winslow. This made General Rosecrans's forces superior to those of Price, and no doubt was entertained he would be able to check Price and drive him back; while the forces under General Steele, in Arkansas, would cut off his retreat. On the 26th day of September, Price attacked Pilot Knob and forced the garrison to retreat, and thence moved north to the Missouri River, and continued up that river towards Kansas. General Curtis, commanding Department of Kansas, immediately collected such forces as he could to repel the invasion of Kansas, while General Rosecrans's cavalry was operating in his rear. The enemy was brought to battle on the Big Blue and defeated, with the loss of nearly all his artillery and trains and a large number of prisoners. He made a precipitate retreat to Northern Arkansas. The impunity with which Price was enabled to roam over the State of Missouri for a long time, and the incalculable mischief done by him, show to how little purpose a superior force may be used. There is no reason why General Rosecrans should not have concentrated his forces, and beaten and driven Price before the latter reached Pilot Knob.
