Lieutenant Houston and privates Donahue and Pugh were captured this morning while scouting just beyond the pickets. Much activity is manifested on our front. Indeed, it is quite generally understood among us that General Lee is taking the initiatory steps of a flank movement upon us. Our scouts so report, and the suspicious movements of the pickets and forces before us corroborate the information. [Illustration: THE CAPTURE--CAVALRY FIGHT AT BUCKLAND MILLS.] CHAPTER XV.

Early in the morning of October tenth the enemy, in heavy force, came down upon our pickets along the Robertson River, driving us back in haste and occupying the fords. The flank movement of General Lee was fully understood. He had crossed the Rapidan, advanced to Madison Court House, and was lapping around our right wing, threatening it with destruction. Quick work on our part was now necessary. Swift messengers from officers high in command brought orders to retire with promptness, but in good order, if possible. Our boys, in many instances, were compelled to leave uneaten and even untasted their palatable preparations for breakfast of roast lamb, sweet potatoes, fine wheat bread, milk and honey, &c., to attend to the stern and always unpleasant duties of a retreat, with the enemy pressing very closely upon us. Sharp skirmishing took place at the river, and the successive crack of carbines afforded the music of our march to James City, where the conflict deepened into a battle, which raged with fury and slaughter. The enemy, conscious of having outgeneraled us in this instance, and having at least a temporary advantage, was bold and defiant. He was met, however, with corresponding vigor. Those contesting legions, which had so often measured sabres in the fearful charge, and hand-to-hand encounter, again appealed to the God of battle, and wrested with Herculean strength for the mastery. Night came on at length to hush the strife, and the weary men and horses sought repose from the bloody fray.
