A plan for a night attack was thereupon laid and committed to Bayard and Kilpatrick. Our instructions were conveyed to us in a whisper. A beautiful moonlight fell upon the scene, which was as still as death; and with a proud determination the two young cavalry chieftains moved forward to the night's fray. Bayard was to attack on the main road in front, but not until Kilpatrick had commenced operations on their right flank by a detour through a neglected and narrow wood-path. As the Heights were considered well nigh impregnable, it was necessary to resort to some stratagem, for which Kilpatrick showed a becoming aptness. Having approached to within hearing distance of the Rebel pickets, but before we were challenged, Kilpatrick shouted with his clear voice which sounded like a trumpet on the still night air. [Illustration: NIGHT ATTACK ON FALMOUTH HEIGHTS.] "Bring up your artillery in the centre, and infantry on the left." "Well, but, Colonel," replied an honest, though rather obtuse captain, "we haven't got any inf----" "Silence in the ranks!" commanded the leader. "Artillery in the centre, infantry on the left." The pickets caught and spread the alarm, and thus greatly facilitated our hazardous enterprise. "Charge!" was the order which then thrilled the ranks and echoed through the dark, dismal woods, and the column swept up the rugged Heights in the midst of blazing cannon and rattling musketry. So steep was the ascent that not a few saddles slipped off the horses, precipitating their riders into a creek which flowed lazily at the base of the hill; while others fell dead and dying, struck by the missiles of destruction which at times filled the air. But the red field was won; and the enemy, driven at the point of the sabre fled unceremoniously down the Heights, through Falmouth, and over the bridge which spanned the Rappahannock, burning the beautiful structure behind them to prevent pursuit. Quite a number of prisoners and various materials of war fell into our hands. Kilpatrick and Bayard were both highly complimented for their personal bravery on the occasion. _April 18._--This morning, at eight o'clock, General Augur took peaceful possession of Falmouth; and here, with military honors, the remains of Lieutenant Decker and about fifteen others, who fell in the late struggle, were interred. Later in the day, and after considerable hesitation, the mayor of Fredericksburg formally surrendered the city to the Yankee General, whose guns on Falmouth Heights commanded obedience.
