CWSAC description
Brig. Gen. J.E.B. Stuart led a brigade-sized mixed force of cavalry, infantry, and artillery to protect a foraging expedition in the vicinity of Dranesville. Union Brig. Gen. E.O.C. Ord, advancing on the Georgetown Pike, encountered Stuart's cavalry. Both sides deployed as more units arrived on the field, and a sharp firefight developed. Stuart withdrew in the mid-afternoon after ensuring that his wagons were safely in the rear.

information

supportedunresolved Stuart says his cavalry discovered Union troops on the ridge and he suspected they were marching on Leesburg or had learned of his forage expedition through a spy. Ord says a few mounted men and a broad mass of smoke convinced him a force was preparing some mischief.

Each commander's inference from what he saw; no intelligence record inspected.

I at once suspected that he was either marching upon Leesburg or had received intelligence through a spy of our intended forage expedi- tion and was marching upon it.

and a broad mass of smoke in that neighborhood, I felt pretty sure there was a force there prepar- ing some mischief.

logistics

supportedunresolved NPS says Stuart was protecting a foraging expedition, and Stuart says his task was to cover all the wagons the army could spare, all of which reached camp safely. Ord says his brigade marched 24 miles, loaded its wagons with forage and carried its wounded back while the division's ambulances lay empty at Washington.

Supply statements from the two commanders and a summary; no quartermaster return inspected.

objectives

supportedunresolved Stuart says his only way to save the wagons was a vigorous attack on the Union rear and left flank, and he withdrew when he judged the wagons out of reach. Ord says he went on to Dranesville, possibly exceeding the letter of his instructions, and covered his foraging party.

Stated aims from the two commanders.

my only way to save them was to make a vigorous attack upon his rear and left flank and to compel him to desist from such a purpose.

outcome

disputedpost_outcome The frozen and live results read Union victory; NPS says Stuart withdrew in mid-afternoon after ensuring his wagons were safe. Ord says the enemy fled, leaving arms, horses, caissons and some dead and wounded; Stuart says he withdrew in perfect order after about two hours as enemy reinforcements arrived, and calls it a success because the wagons were saved.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit.

disputedpost_outcome The frozen and live casualty fields read 301 (US 71; CS 230). Ord reports 7 killed and 60 wounded (read 'GO' in OCR), estimates the Confederate dead left on the field at 50 to 75 and says 21 badly wounded were left behind. Stuart's table totals 43 killed, 143 wounded and 8 missing, noting that only 27 were found dead on the field, and says the enemy lost over 50 killed.

responsibility

supportedunresolved The frozen commanders are Brigadier General J.E.B. Stuart and Brigadier General Edward O.C. Ord; the live page gives Ord as Brigadier General and 'James Stuart' without rank. Ord says he placed the guns himself and pushed the infantry forward, and that McCall arrived between 3 and 4 p.m. and directed him to continue; Reynolds's brigade arrived too late. Stuart says he directed the regiments' positions, withdrew the battery and then ordered the regiments to disengage.

Command roles from the two reports; McCall's own reports were not selected. No automatic sole credit.

strength

unknownunresolved

No inspected return establishes matched personnel at a common opening boundary. The frozen side-specific numerical strength bounds are blank (missing_numeric_strength). No figure in this pass is adopted as a simultaneous opening force.

disputedunresolved The frozen force field reads Brigades; the live field reads zero; NPS calls Stuart's force brigade-sized. Ord took his brigade, the First Rifles, Easton's battery and two cavalry squadrons, and says prisoners reported four regiments and a six-gun battery under Stuart. Stuart reported four regiments and four guns, 'say 1,200 strong', on December 21, and on December 23 an aggregate of 1,600 infantry with 150 cavalry and four guns; he put the enemy at five to ten regiments with six or seven guns ('They said 3,100') and, from citizens, fifteen regiments.

Stuart's two figures differ, as do the gun counts. None is adopted as a matched opening strength. The live zero is not measured absence.

terrain

supportedunresolved Ord says the attack came from a thickly wooded hill on his right, with the Confederate guns about 500 yards off in a road he could enfilade. Stuart says his infantry was screened in dense pines, but his guns had no outlet from the road for a mile and the enemy's battery raked the straight road behind them.
