With the details of the overwhelming disaster to the Federal arms, at Manassas, on the 21st of July, we are not here interested. Our aim has been to glance briefly at the relations sustained by President Davis to the preliminary campaign which culminated in success so brilliant and valuable. In accordance with his preconceived purpose to be present, if possible, at the consummation of plans in which he felt so profound an interest, President Davis left Richmond on Sunday morning, July 21st, for the scene of the expected battle. Reaching the battle-field while the struggle was still in progress, it was his privilege to witness the flight, in utter confusion and dismay, of the Federal hosts in their first serious conflict with the patriot army. His presence upon the field was the inspiration of unbounded enthusiasm among the troops, to whom his name and bearing were the symbols of victory. His dispatch from the battle-field, on Sunday night, will long be remembered by those who gathered from it their first intelligence of the great victory: "MANASSAS JUNCTION, Sunday Night. "Night has closed upon a hard-fought field. Our forces were victorious. The enemy were routed, and precipitately fled, abandoning a large amount of arms, knapsacks, and baggage. The ground was strewn for miles with those killed, and the farmhouses and ground around were filled with the wounded. Pursuit was continued along several routes towards Leesburg and Centreville, until darkness covered the fugitives. We have captured many field batteries and stands of arms, and one of the United States flags. Many prisoners have been taken. Too high praise can not be bestowed, whether for the skill of the principal officers, or the gallantry of all our troops. The battle was mainly fought on our left. Our force was 15,000; that of the enemy estimated at 35,000. "JEFF'N DAVIS." He remained at Manassas, in consultation with Generals Beauregard and Johnston, until the morning of Tuesday, July 23d. The return of the President to Richmond was the occasion of renewed patriotic rejoicings. An immense crowd awaited at the railroad depot, in expectancy of his arrival, and both there and at his hotel occurred most enthusiastic demonstrations of popular delight at the success of the army, and of public regard for himself.[38] At night Mr. Davis addressed, with thrilling effect, an immense audience, from a window of the Spottswood Hotel, recounting some of the incidents of the battle, which he declared to be a decisive victory, if followed by energetic measures, and counseled moderation and forbearance in victory, with unrelaxed preparations for future trials. It was upon this occasion that he uttered the memorable injunction, "Never be haughty to the humble, or humble to the haughty."
