Harpers Ferry WV010

supportedunresolved Palfrey quotes Lee that the advance on Frederick had been expected to cause Harper's Ferry's evacuation, and reports McClellan's statement that a messenger said Miles could hold out two days longer.

Attributed beliefs relayed through Palfrey; Palfrey himself doubts the Miles message. No original message was inspected.

supportedpost_outcome Palfrey says the surrender included 73 pieces of artillery, many small arms and other stores.

Post-outcome material consequence from one retrospective history; no inspected inventory.

supportedunresolved Palfrey quotes Lee that it became necessary to dislodge the Union forces before concentrating west of the mountains; NPS says Lee decided to surround and capture the garrison.

Attributed purpose from a quoted report and a modern summary; no inspected order.

supportedpost_outcome The frozen result remains Confederate victory. Palfrey says it succeeded completely but took longer than Lee anticipated.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. Palfrey's view that the delay nearly proved fatal to Lee is campaign contribution, not this record's result.

disputedpost_outcome The frozen casualty text reads 12,922 total (US 44k/173w/12,419 captured; CS 39k/247w); the live NPS field reads 13005 total (US 12719; CS 286;).

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. Captured troops dominate the Union figure and are not an opening strength; Palfrey's 11,000 surrendered is another scope.

supportedinherited Palfrey quotes Halleck's telegram that Miles could not join McClellan and must defend his works, after McClellan had suggested ordering him out; Palfrey calls this an error of principle.

The decision to keep the garrison in place came from the General-in-Chief, not the listed field commander; Palfrey's judgment is attributed, not a causal estimate.

disputedunresolved NPS says Miles surrendered and was mortally wounded by a last salvo; Palfrey says White succeeded to command when Miles was mortally wounded and surrendered. The frozen commanders are Miles and Jackson; Palfrey describes Jackson, McLaws and Walker converging in separate columns.

Who surrendered the garrison differs between the sources and is not resolved. No listed commander receives automatic sole credit for a converging operation by several columns.

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 says Corps; the live field reads zero. Palfrey gives 9,000 men at Harper's Ferry under Miles and 2,500 at Martinsburg under White, who retreated there; he says White surrendered 11,000 men. NPS says Miles surrendered a garrison of more than 12,000.

The garrison changed as Martinsburg's troops arrived; the sources give different totals and scopes. No figure is adopted as a matched opening population, and surrender counts are not opening strengths.

supportedunresolved Palfrey says Maryland Heights commanded Harper's Ferry with a plunging fire, so the town was untenable once the Confederates held them; NPS says surrender followed placing artillery on the heights.

Physical position description; no map verification or numerical terrain effect. Occupying the heights was a Confederate action, not an inherited advantage.
