Major-General Alfred Pleasonton was assigned to duty as second in command of the Missouri department, by order of Major-General Rosecrans.
An expedition, under command of General Graham, consisting of the army gunboats, the Ninth New Jersey, the Twenty-third and Twenty-fifth Massachusetts, the One Hundredth and the Eighteenth New York regiments, and two sections of artillery, under Captain Easterly, left Fortress Monroe last night, and landed at different points. They concentrated at Smithfield, Va., this evening, and succeeded in routing the enemy, capturing one commissioned officer and five men — all wounded; also several horses and carriages, and some commissary stores. A rebel mail, and one piece of artillery, formerly taken from the gunboat Smith Briggs, were also captured. Fifty contrabands were brought off at the same time. The Union loss was one missing, and five slightly wounded.
This morning, a force of confederate cavalry, estimated at some twenty in number, and supposed to be a portion of Captain Jumel's command, stationed on the Grosse Tete, appeared in front of the village and park on the opposite side of the Bayou Plaquemine, La., and a party being detailed, crossed over and set fire to all the cotton at that place, while parties were at the same time engaged in burning that on flatboats at the village.--Plaquemine Gazette and Sentinel.
