POWELL CLAYTON, Col Cdg

ST. LOUIS, Wednesday, April 6. The following particulars of Col CLAYTON’s recent raid in Arkansas have been received from Little Rock, March 27.

Col. CLAYTON, with a small force of cavalry and infantry, and one battery, went to Mount Elba, on the Salem River. Leaving the infantry and artillery there to guard the bridge, and cover Pine Bluff, he proceeded with the cavalry toward Longview, further down the Salem, and 20 miles southwest, where the main body of the rebel army was stationed, for the purpose of destroying the pontoon bridges and the army stores at that place.
Lieut. GREATHOUSE, of the First Indiana, and Lieut. YOUNG, of the Fifth Kansas Cavalry, sent an advance of 100 men, and arriving at the bridge saw a large force of rebels opposite preparing to cross. Our officers hailed the enemy, told them they belonged to SHELBY's command, (which dresses in Federal uniform,) informed them that the Federals were upon them, and begged them to hurry to their rescue.
The rebels rushed forward, and as fast as they crossed were captured, and their guns thrown into the river. In this way 260 were captured, and 35 wagons laden with supplies, taken, which were destroyed; also, 300 horses and mules. A paymaster's safe, containing $60,000 in Confederate money was also captured. The bridge was afterward burned.
This and the march of 80 miles was accomplished in 24 hours.
The prisoners captured during the expedition, numbering 370, including many officers, reached Little Rock on the 2d.
