A force of Gen. Stuart's rebel cavalry made a dash at Catlett's Station, Va., and destroyed or carried off a great quantity of sutler's and other stores, sacked the hospital, captured Gen. Pope's wagons with all his papers, etc., and then proceeded towards Warrenton.--(Doc. 188.)
President Lincoln, in response to a letter written by Horace Greeley, stated that his paramount object was the restoration of the Union, and not the safety or destruction of slavery. If he could save the Union without freeing the slaves, he would do it; if he could save it by freeing all the slaves, he would do it; and if he could save it by freeing a portion and leaving others alone, he would do that.--See Supplement.

This morning, at five o'clock, the rebels opened fire from their batteries along the whole line of the army on the Rappahannock. The Union army on the opposite bank of the river promptly replied, and the cannonade was kept up, with short intermissions, all day. The principal attack was on the Union centre, occupied by General McDowell's army corps. At about nine A. M., the cannonading having almost ceased, Gen. Sigel ordered Gen. Schurz to ford the river with a brigade of his division, and reconnoitre the enemy's  position on the opposite side. When about a mile from the river, Gen. Schurz discovered the rebels, who, after receiving a volley or two, precipitately retreated, in the hope of drawing the Unionists into an ambush. This failed. General Schurz took up his position, and in turn was attacked by the rebels in force. A fierce battle ensued, which lasted until six P. M., when, the Unionists not being sufficiently strong to hold the advanced position, retired to the north bank of the river, and joined the main body of the army.--(Doc. 104.)
