In faut, up to that mcmeut, I had nover was'et't'd in tliu eonviction that triuraph must crown our arras. Nor was my confidenoe shaken m, at the time I have mentioned, I vod on the extreme left, at tho dMtanue of somotbing more than a milo, a column of men approaohing. At their bead was a flag whioh I could not dia Inguinh. Even with the aid ol a trong gl8i I WÍ1S unible 10 detornioe whcther it was the United Stutos flitg, or tho Confaderoto flag.

Patterson's commund coming to rein force MeDowell. At this moment, I must confesa, my heart fuiled me. I came, reine: atit'ly, to the conclusión thut, after all oureftbrts, we shouid at lust be oompelled to yield to the enerny the hard-fought and bloody field. I again took the glafs to examine the flag ol tho p.pproaching column, but my anxioui inquiry wu improductivo oi result, I could not teil to which nrrny the waving haunur belonged. At thia time a number of my stuff were absent, having been dispatcbed with ordeiü to vurious points, The only person with me was the gnlhint oiücer who has recently distinguished bimself by a brilliant 'fout of arm - Gkneral, thon Oolonel, Evans. To him [ communioat&d my doubts and foiirs. I told him I fearód the approaching i'.rcü was in reality Pattereon's división; thatif suoh was the oase I should be oompelled to fall back upon our own reserves, and postpone till the next day a oontinuation of the engagement After lurther reflection, I directed Col. Evans to proceed to Gen. Johnnton, who had tisumed the task of collec tiog a reserve, and to inform him ol the eircumstances of the case, and to ■quest himto have the reserves collected with all diapatch, and hold them in readine to support our retrograde movement. Col. Evans started on the mision thus intrusted to him.
