We print this morning, from our special correspondent at St. Louis, a letter concerning the position of Gen. Fremont, the state of St. Louis, and the recent visit of the Secretary of War.

THE LATEST
WAR
NEWS.

The condition of the Potomac now chiefly occupies the minds of people at Washington. It appears that though there are upon the banks many guns, they cannot easily reach the ships as they pass; consequently the risk of the passage is very small. Reconnoissances show that at Leesburg the Rebel force is not large, and that the enemy is evacuating the place as rapidly as possible; the same is true of Fairfax Court-House. Beauregard is said to have withdrawn to Manassas, leaving a strong guard at Centreville, and it is believed by some that at the latter place a fight may be made when our army advances.

It is reported from Missouri, that Gen. Wyman, with 2,500 men, has arrived at Lynn Creek, where he dispersed a body of rebels, killing a large number, taking more than 200 prisoners, and capturing a great quantity of property which the enemy had stolen. Gen. Fremont, on Friday night, was still at Warsaw; the pontoon bridge, constructed by him over the Osage river, was to be finished on Saturday: Sigel's division had crossed the river. It was reported that Ben McCulloch had reinforced Price at Osceola, and that this combined army had fortified that town and there waited to give battle to Gen. Fremont. Another dispatch says that it is Carthage where Price means to make his stand. Still another report concerning Rebel affairs in Missouri states that Gen. Johnston has been placed in command of all the Rebels in that State: but it is not intimated whether he supersedes Price or not. All the reports from that section imply clearly that a hard battle, with a large force on each side, must soon be fought there. The City of Lexington was re-captured by Maj. White on the 16th inst. A large number of our wounded were released, and a number of the rebel garrison were captured, together with their arms, etc. The inhabitants, who had been plundered, were found to be in a deplorable condition.
