Kernstown, First VA101
1862-03-23 to 1862-03-23 · VA · Jackson's Valley Campaign [March-June 1862] · frozen result: Union · NPS summary (as listed)
Relying on faulty intelligence that reported the Union garrison at Winchester numbered only about 3,000, "Stonewall" Jackson marched aggressively north with his 3,400-man division. The 8,500 Federals, commanded by Col. Nathan Kimball, stopped Jackson at Kernstown and then counterattacked turning Jackson's left flank and forcing him to retreat. Despite this Union victory, President Lincoln was disturbed by Jackson's threat to Washington and redirected substantial reinforcements to the Valley, depriving McClellan's army of these troops. McClellan claimed that the additional troops would have enabled him to take Richmond during his Peninsula campaign.

information
supportedunresolved The NPS narrative attributes Jackson’s advance to an estimate of about 3,000 Union troops; Allan describes information received through Ashby that understated the remaining force.
Both are retrospective accounts. The original report, its delivery and Jackson’s exact knowledge were not inspected; agreement does not establish independent corroboration.

No battle-specific supply, ammunition or transport return was inspected. Formation lists and retrospective descriptions are not readiness measures.

Retrospective account of purpose, not a measured strategic benefit or an inspected original order. The recorded tactical defeat remains a Union victory.

supportedpost_outcome The frozen result remains Union victory.
Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit.
supportedpost_outcome The frozen casualty text reads 1,308 total (US 590; CS 718). The live NPS field reads 1308 total (US 590; CS 718;).
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.

952b5d08402a…responsibility
supportedunresolved Allan identifies Kimball as the senior officer commanding on the field in Shields’s absence.
Field command and divisional authority are different roles; neither receives automatic sole credit. The live heading calls Kimball brigadier general but the narrative and frozen listing call him colonel; the heading does not revise the frozen rank or establish a transfer clock.

No inspected return establishes matched personnel at a common opening boundary. Imported numerical estimates remain unchanged; this pass does not validate them as simultaneous opening forces.

Source field only. Formations, engaged troops and changing concentrations do not establish matched opening populations. Live zeros are not measured absence; shared provenance is not independent corroboration.

Retain the internal discrepancy without choosing a canonical figure or assuming equal population/timing. Imported numerical bounds remain unchanged.

08a742ed11b5…Open questions
- Original orders, returns, casualty reconciliation, contemporary message chains and precise command clocks remain deferred after the bounded pass. No whole-book, facsimile or map verification is claimed.
- NPS/CWSAC is one family; Allan is one interested retrospective history where used. Embedded reports are not additional independently inspected families. Princeton retains only the frozen NPS/CWSAC family.
- No automatic commander attribution, causal campaign score, morale/readiness number or battle/campaign double counting.
