Manassas Station Operations VA024

1862-08-25 to 1862-08-27 · VA · Northern Virginia Campaign [August 1862] · frozen result: Confederate · NPS summary (as listed)

CWSAC description
On the evening of August 26, after passing around Pope's right flank via Thoroughfare Gap, Jackson's wing of the army struck the Orange & Alexandria Railroad at Bristoe Station and before daybreak August 27 marched to capture and destroy the massive Union supply depot at Manassas Junction. This surprise movement forced Pope into an abrupt retreat from his defensive line along the Rappahannock River. On August 27, Jackson routed a Union brigade near Union Mills (Bull Run Bridge), inflicting several hundred casualties and mortally wounding Union Brig. Gen. G.W. Taylor. Ewell's Division fought a brisk rearguard action against Hooker's division at Kettle Run, resulting in about 600 casualties. Ewell held back Union forces until dark. During the night of August 27-28, Jackson marched his divisions north to the First Manassas battlefield, where he took position behind an unfinished railroad grade.

information

supportedunresolved Ropes says Jackson marched some fifteen miles behind the Union army without its knowledge, that Pope thought the railroad cut by cavalry, and that only after the Bristoe fight did Pope learn Jackson's whole corps was there.

Retrospective reconstruction of knowledge; Pope's despatches are quoted, not inspected. NPS calls the move a surprise, which is also a summary judgment.

outcome

supportedpost_outcome The frozen result remains Confederate victory. Ropes says Hooker drove Ewell back across Broad Run while Taylor's attack failed.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The aggregate record combines actions with different local outcomes.

disputedpost_outcome The frozen casualty text reads 1,100 total; the live NPS field reads 0 total. The NPS narrative gives about 600 casualties at Kettle Run and several hundred at Bull Run Bridge.

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. Component figures are not added to the aggregate.

responsibility

supportedunresolved Stuart, as ranking officer, commanded the night capture with Trimble; Taylor led the Union attempt to retake the post and was mortally wounded; Ewell fought Hooker at Bristoe under orders to retire if pressed.

Several separate commands inside one aggregate record; the listed commanders Jackson and Taylor do not receive 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.

supportedunresolved The frozen force field says Divisions; the live field reads zero. Ropes puts Jackson's three divisions at some twenty-five thousand, and describes separate encounters with Taylor's New Jersey brigade and Hooker's division.

An aggregate operation with several separate encounters; no matched opening population. Live zeros are not measured absence.
