Flushed with success, the guerillas were making preparations to retire from the field with their booty, when the Fifth New York Cavalry, which had been bivouacked in a grove not far from Cedar Run Bridge, arrived at the Junction, whither they had been attracted by the firing, and immediately fell upon the foe like an avalanche. Major Hammond commanded in person. Mosby was heard to exclaim, "My God! it is the Fifth New York!" A hand-to-hand encounter now took place, in which bravery was fired with desperation, and Yankee sabres were used with fearful effect. The Rebels soon broke and fled in every direction, demoralized and panic-stricken, leaving behind not only the captures they had made, but many of their own number. Some Rebel heads were fearfully gashed and mangled, one of them exhibiting his lower jaw-bone not only dislocated, but almost entirely severed with one determined blow from the strong hand of a cavalryman. General Stahel, in his despatch to General Heintzelman, says: "The Rebels, who fled in the direction of Warrenton, were pursued by Major Hammond, Fifth New York Cavalry, who has returned, and reports our charge at Warrenton Junction as being so terrific as to have thoroughly routed and scattered them in every direction. I have sent in twenty-three prisoners of Mosby's command, all of whom are wounded--the greater part of them badly. Dick Moran (a notorious bushwhacker) is among the number. There are also three officers of Mosby's. The loss of the enemy was very heavy in killed, besides many wounded, who scattered and prevented capture. I have no hopes of the recovery of Major Steele, of the First Virginia. Our loss is one killed and fourteen wounded." Templeman, one of Stonewall Jackson's best spies, was killed; and the partisans confessed themselves thoroughly whipped. They were wont to call this their first retreat, in which they did some tall running. The following complimentary order was issued: HEADQUARTERS STAHEL'S CAVALRY DIVISION, Fairfax Court House, Va., ----, 1863. SPECIAL ORDERS NO. 80. When soldiers perform brave deeds, a proper acknowledgment of their services is justly their due. The commanding general, therefore, desires to express his gratification at the conduct of the officers and men of Colonel De Forest's command, who were engaged in the fight at Warrenton Junction, on Sunday, ----, 1863. By your promptness and gallantry the gang of guerillas who have so long infested the vicinity has been badly beaten and broken up. The heavy loss of the enemy in killed, wounded, and prisoners, proves the determination of your resistance and the vigor of your attack. Deeds like this are worthy of emulation, and give strength and confidence to the command. By command of MAJOR-GENERAL STAHEL.
