Right Wing, and much of his Army was badly demoralized; but, on the
other hand, it may be well to repeat that the Enemy's plan of attack
that same morning had been frustrated, and most of his forces so badly
shattered and demoralized that he dared not follow up the advantage
which, more by our own blunders than by his prowess, he had gained.

If the Union forces--or at least the Right Wing of them--were whipped,
the Enemy also was whipped. Jackson himself confesses that while he
had, at the last moment, broken our centre, our forces had turned both
of his flanks. The Enemy was, in fact, so badly used up, that he not
only dared not pursue us to Washington--as he would have down had he
been able--but he was absolutely afraid McDowell would resume the
attack, on the right of the original Bull Run line, that very night!
For, in a letter to General Beauregard; dated Richmond, Virginia, August
4, 1861, Jefferson Davis,--who was on the ground at Bull Run, July
21st,--alluding to the Battle of Bull Run, and Beauregard's excuses for
not pursuing the Union troops, says:

"I think you are unjust to yourself in putting your failure to pursue
the Enemy to Washington, to the account of short supplies of subsistence
and transportation. Under the circumstances of our Army, and in the
absence of the knowledge since acquired--if, indeed, the statements be
true--it would have been extremely hazardous to have done more than was
performed. You will not fail to remember that, so far from knowing that
the Enemy was routed, a large part of our forces was moved by you, in
the night of the 21st, to repel a supposed attack upon our right, and
the next day's operations did not fully reveal what has since been
reported of the Enemy's panic."

And Jefferson Davis's statement is corroborated by the Report of Colonel
