Now farewell, O hero! In our Glory's Pantheon Thy name will shine, a name immortal won By deeds immortal! In our heart's deep heart Thy statued fame, that never shall depart, Shall tower, the loftier as Time fleets, and show How Heaven can sometimes plant its Titans here below." General Pope, during all the day, and most of the night, hastened his retreat, and on the second of September, his broken and demoralized columns found rest and rations within the fortifications which guard the approaches to Washington. Thus ended General Pope's brief and trying career as commander of the Army of Virginia. Here he resigned his command, and was succeeded by General McClellan. CHAPTER VI.

By the almost continual fighting of General Pope's campaign, our ranks had been greatly depleted. Of the cavalry in general one correspondent makes the following remark: "They picket our outposts, scout the whole country for information, open our fights, cover our retreats, or clear up and finish our victories, as the case may be. In short, they are never idle, and rarely find rest for either men or horses." We had felt the influence of this wear and tear so sadly, that our once full and noble regiment was now reduced to about three hundred and fifty men, scarcely one third of our original number. Nearly every regiment of cavalry which had participated in the misfortunes of the campaign, had suffered a like decimation. To replenish our weakened ranks and to infuse new vigor and discipline into the various commands, became a question of no little moment. Consequently a large number of regiments, under the direct supervision of General Bayard, were ordered to Hall's Hill, about ten miles from Washington, where we established camps of instruction and drill.
