Manassas Gap VA108
1863-07-23 to 1863-07-23 · VA · Gettysburg Campaign [June-July 1863] · frozen result: Inconclusive · NPS summary (as listed)
After recrossing the Potomac River at Williamsport, Lee's army withdrew up the Shenandoah Valley. Meade crossed the Potomac River east of the Blue Ridge and followed Lee into Virginia. On July 23, Meade ordered the III Corps, under Maj. Gen. William. H. French to cut off the retreating Confederate columns at Front Royal by forcing passage through Manassas Gap. At first light, French began slowly pushing Walker's Confederate brigade (Anderson's division) back into the gap. About 4:30 pm, a strong Union attack drove Walker's men until they were reinforced by Rodes's division and artillery. By dusk, the poorly coordinated Union attacks were abandoned. During the night, Confederate forces withdrew into the Luray Valley. On July 24, the Union army occupied Front Royal, but Lee's army was safely beyond pursuit.

00c3e0691eba…responsibility
supportedunresolved NPS calls the Union attacks poorly coordinated. Humphreys says the Excelsior brigade under Spinola charged and drove its opponent back with severe loss. Lee says Ewell supported Wright with Rodes's division. The frozen and live commanders are French and Anderson, both Major Generals.
Judgments are attributed; the frozen commanders do not receive automatic sole credit.

- French's, Spinola's, Ewell's and Wright's reports and the returns remain deferred.
- NPS/CWSAC is one family. Doubleday is an interested participant history (he commanded the First Corps at Gettysburg) and Humphreys an interested history by the Army of the Potomac's chief of staff in 1863–64, per his publisher's list; both drew on official papers. Lee's and Stuart's reports, printed in Official Records Series I, Volume XXVII, Part 2, are separate families of interested commanders' accounts; the volume is a shared container, not an additional witness. Report dates are not event times or proof of contemporary knowledge.
- No automatic commander attribution, causal campaign score, morale/readiness number or battle/campaign double counting.
