Indeed, before leaving Manassas, President Davis favored the most vigorous pursuit practicable. On the evening of the battle, while the victory was assured, but by no means complete, he urged that the enemy, still on the field, (Heintzelman's troops, as subsequently appeared,) be warmly pressed, as was successfully done. During the night following the engagement he made a disposition of a portion of the troops, with a view to an advance in the morning. These troops were removed, but not by himself, to meet an apprehended attack upon the head-quarters of the army. An advance on Monday, the 22d July, was out of the question, in consequence of the heavy rain. It is not to be understood that President Davis fully appreciated, on Sunday night, the 21st, the overwhelming rout of the Federal army, nor that he advocated, as practicable, an immediate movement in pursuit, by the entire army. No one could have anticipated the utter disorganization attending the flight of the Federals. He had, too, positive evidence of the confusion prevailing among portions of the Southern troops. Summoned by a message from a youthful connection, who was mortally wounded, Mr. Davis rode over a large portion of the field, in a vain search for the regiment to which the young man was attached. Upon his return, he accidentally met an officer who directed him to the locality of the regiment, where he found the corpse of his relative. The evidences of disorganization, upon which General Johnston dwells with so much force and emphasis, were indeed palpable, but Mr. Davis confidently believed that an efficient pursuit might be made by such commands as were in comparatively good condition. Such were his impressions then, and that he contemplated immediate activity as the sequel of Manassas, is a matter of indisputable record. That Mr. Davis did not insist upon the undeferred execution of his own views, is proof less of his approval of the course pursued, than of an absence of that pragmatic disposition with which he was afterwards so persistently charged. His subsequent hearty tributes to Beauregard and Johnston, and prompt recognition of their services, show how far he was elevated above that mean intolerance, which would have made him incapable of according merit to the opinions and actions of others, when averse to his own conclusions.
