CWSAC description
Maj. Gen. J.E.B. Stuart, screening Lee's invasion route, sparred with Pleasonton's cavalry. On the June 17, Col. Alfred Duffié's isolated 1st Rhode Island Cavalry Regiment was attacked by the brigades of Munford and Robertson. The 1st Rhode Island Cavalry was routed, taking about 250 casualties. On June 19, J. Irvin Gregg's brigade advanced, driving Stuart's cavalry one mile beyond the town. Both sides were reinforced and mounted and dismounted skirmishing continued. Stuart was gradually levered out of his position but fell back to a second ridge, still covering the approaches to the Blue Ridge gap.

information

supportedunresolved Stuart says Mosby captured Hooker's dispatches to Pleasonton, disclosing Hooker's concern for Aldie, a planned cavalry reconnaissance and the number of Union divisions. Doubleday says Duffié was not aware of any impediment toward Aldie.

Attributed knowledge from Stuart's report and an interested history; the dispatches were not inspected.

logistics

supportedunresolved Stuart says that on June 19 rough roads had already decimated two of his brigades, Robertson's and W. H. F. Lee's (under Chambliss), for want of adequate shoeing facilities. He places a continuous rain on June 20, after the frozen Middleburg interval.

Condition statements from the Confederate commander's report; no inspected return. The rain statement falls between the Middleburg and Upperville frozen dates and is context, not an in-interval condition.

objectives

supportedunresolved NPS says Stuart was screening Lee's invasion route. Stuart says he did not seek a general engagement while awaiting Jones's and Hampton's brigades, and that his operations were necessarily defensive while masking the movement of Lee's main body.

Stated aims from a summary and the Confederate commander's report; no inspected orders.

outcome

supportedpost_outcome The frozen result reads Inconclusive and the live result Indecisive. NPS says the 1st Rhode Island was routed on June 17, and that on June 19 Gregg drove Stuart a mile beyond the town before Stuart fell back to a second ridge still covering the Blue Ridge approaches. Doubleday says Duffié was driven out and fought his way back to Centreville.

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 casualty text reads 390 total; the live field reads zero. NPS says the 1st Rhode Island took about 250 casualties; Stuart says Robertson took 70 prisoners and a standard.

Original casualty returns were not inspected; preserve totals, categories, cutoffs and differences. No canonical reconciliation or casualty-based opening count; related actions must not be added without resolving population overlap. Stuart's loss of 65 killed, 279 wounded and 166 missing is for 'these operations': his Loudoun narrative from June 17 through the June 22 pursuit toward Aldie, including Aldie, Middleburg, Upperville, Hampton's action at Warrenton and the June 20 skirmishing beyond Goose Creek. It is not assigned to one engagement. The regiment's 250 is one part of the frozen interval.

responsibility

supportedunresolved Doubleday relays Stuart's statement that he could not with his entire force drive the First Rhode Island from its chosen position. Stuart says he ordered Robertson to attack the enemy at Middleburg at once. The frozen commanders are Stuart, a Major General, and D. M. Gregg, a Brigadier General; the live heading gives Stuart no rank.

Judgments are attributed; the frozen commanders do not receive automatic sole credit.

Stuart states that he was un- able with his entire force to drive the First Rhode Island regiment from a position it had chosen,

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 Divisions and the live field zero. NPS says Duffié's isolated 1st Rhode Island Cavalry was attacked on June 17 by Munford's and Robertson's brigades; Doubleday calls Duffié's command a division and says Stuart concentrated his forces against it. On June 19 NPS says J. Irvin Gregg's brigade advanced.

The Union force on June 17 is a regiment in NPS and a division in Doubleday; no count is given. Live zeros are not measured absence.

terrain

supportedunresolved Doubleday says Duffié barricaded the streets and sheltered his men behind stone walls and barricades. Stuart says that on the 19th a woodland in front of his line exposed his charges to carbine fire, so he withdrew half a mile to a more commanding position; NPS says he fell back to a second ridge.

Positions taken during the interval by both sides; boundaries unset and no map verification.
