At that sound Stuart leaped to the saddle, and rode rapidly toward the front. Fifteen minutes afterward his head-quarters had vanished. On the green slope of Fleetwood not a tent was visible. Is the reader familiar with the country along the Upper Rappahannock? If so, he will remember that the river is crossed in Culpeper by numerous fords. The principal--beginning on the left, that is to say, up the river--are Welford’s, Beverly’s, the Railroad bridge, and Kelly’s fords. Stuart’s left, under William H.F. Lee, was opposite Welford’s; his centre, under Jones, opposite Beverly’s; his right, under Hampton, toward Kelly’s; and a force under Robertson was posted in the direction of Stevensburg, to guard the right flank. The whole amounted to about seven or eight thousand cavalry. The Federal column which now advanced to attack it, is said to have embraced all the cavalry of General Hooker’s army; and must have numbered more than twelve thousand sabres. Stuart rode on rapidly down Fleetwood Hill, and was soon opposite Beverly’s Ford where the enemy had crossed in force. General Jones was heavily engaged, and the Napoleons of the horse artillery were roaring steadily. Every moment the round shot crashed, or the shell tore through the woods about three hundred yards in front of the pieces where the dismounted cavalry of the enemy had effected a lodgment. They kept up a hot fire at the cannoneers, and the steady rattle of carbines further up the river told that Lee was also engaged. In face of the bursting shell, the blue _tirailleurs_ could not advance; and Stuart sent an order to Hampton to move in and attack on the right. The troopers of the Gulf States advanced at the word; their dense column was seen slowly moving, with drawn sabre, across the plain; the moment of decisive struggle seemed rapidly approaching, when suddenly a heavy blow was struck at Stuart’s rear. I had been directed by him to ascertain if “every thing had been sent off from Fleetwood,” and to see that no papers had been dropped there in the hurry of departure. Going back at a gallop I soon reached the hill, and rode over the ground recently occupied by the head-quarters. The spot seemed swept. Not a paper was visible. All that I could see was a withered bouquet dropped by some young officer of the staff--a relic, no doubt, of the last night’s ball at the village. I had already turned to ride back to Stuart, when my attention was attracted by a column of cavalry advancing straight on Brandy--that is, upon Stuart’s rear. What force was that? Could it be the enemy? It was coming from the direction of Stevensburg; but how could it have passed our force there? “Look!” I said to an officer of the horse artillery, one battery of which was left in reserve on the hill, “look! what column is that?” “It must be Wickham’s,” was his reply. “I am sure they are Yankees!” “Impossible!” he exclaimed.
