James M. Graham, Assistant Adjutant-General, sent the following despatch from Leaven-worth, Kansas, to the War Department at Washington:
Major Champion Vaughan, of General Blunt's staff, has arrived at these headquarters with despatches. Gen. Blunt marched with one thousand five hundred men from Fort Scott, August  seventeenth, and followed the rebels as far north as Lone Jack. The enemy declined an engagement and commenced a retreat. They were hotly pursued by Gen. Blunt, and driven in utter confusion across the Osage, with the loss of all their transportation and equipments, besides numerous arms, prisoners, etc. It is considered that the expedition saved the Missouri towns and the western border from devastation, besides striking terror into the hearts of the enemy as far as the Arkansas line. Gen. Blunt's column returned to Fort Scott on the twenty-second, having marched nearly three hundred miles in six days. Col. Cloud was left to continue the pursuit, and it is not improbable that the main force of the rebels will be forced to surrender.
