Hunter has not yet been heard from: three couriers have been sent after him. General Pope is now in command here. It is understood, that, until the Commanding General arrives, the army will stand upon the defensive, and that no engagement will take place, unless it is attacked. General Fremont and his staff will leave to-morrow for St. Louis. This evening I rode through Sigel's and McKinstry's camps. The general order and the farewell address had been read to the regiments, and the camp-fires were surrounded by groups of excited soldiers, and cheers for Fremont were heard on every side. _November 3d, 8 P.M._ This morning it became apparent that the departure of the General before the arrival of Hunter would endanger the discipline of the army. Great numbers of officers have offered their resignations, and it has required the constant and earnest efforts of General Fremont to induce them to retain their positions. The slightest encouragement upon his part of the discontent which prevails will disorganize the divisions of Sigel and Asboth. The attitude of the enemy is threatening, and it does not seem possible to avoid a battle more than a few hours. Great numbers of people, flying before Price, have come in to-day. A reconnaissance in the direction of Springfield has been made, and the following report rendered by General Asboth. "HEAD-QUARTERS FOURTH DIVISION WESTERN DEPARTMENT. "_Springfield, November 3d, 1861._ "To MAJOR-GENERAL J.C. FREMONT, _Commanding Western Department._ "GENERAL:--The captain commanding the company of Major Wright's battalion, which was sent out on a scouting party to Wilson's Creek, has just sent in his report by a runner. He says, last night the enemy's advanced guard, some two thousand strong, camped at Wilson's Creek. Price's forces are at Terrill's Creek on the Marionsville road, nine miles behind Wilson's Creek, and McCulloch's forces are at Dug Springs. "Both these forces were expected to concentrate at Wilson's Creek to-night, and offer battle there. "The scout depicts every road and path covered with moving troops, estimating them at forty thousand men. "Very respectfully, "Your obedient serv't, "ASBOTH, "Act. Maj.-Gen'l Com'd'g 4th Div." According to this report, the whole of Price's army is within twenty miles of us, and probably nearer. Hunter has not been heard from, and it is impossible to discover his whereabouts. This afternoon General McKinstry designed to make a reconnaissance in force with his whole division towards Wilson's Creek; but yielding to the solicitations of the chief officers, and in view of the imminence of battle, to-day General Fremont resumed the command, and ordered McKinstry not to make his reconnoissance,--not wishing to bring on a general engagement during the absence of Hunter.
