Deep Bottom I VA069
1864-07-27 to 1864-07-29 · VA · Richmond-Petersburg Campaign [June 1864-March 1865] · frozen result: Confederate · NPS summary (as listed)
During the night of July 26-27, the Union II Corps and two divisions of Sheridan's cavalry under command of Maj. Gen. Winfield Scott Hancock crossed to the north side of James River to threaten Richmond. This demonstration diverted Confederate forces from the impending attack at Petersburg on July 30. Union efforts to turn the Confederate position at New Market Heights and Fussell's Mill were abandoned when the Confederates strongly reinforced their lines and counterattacked. During the night of July 29, the Federals recrossed the river leaving a garrison as heretofore to hold the bridgehead at Deep Bottom.
Command responsibility (ledger v2)
US: Winfield Scott Hancock
Grade A under rule 2; echelon corps_or_wing. superior_directing
Single CWSAC listing. The description puts the II Corps and two cavalry divisions under Hancock's command; Hancock's report has him decide to cross the infantry at the lower bridge and turn the position. Humphreys says Grant determined to send the force, and Hancock was told Grant did not want the works attacked (superior_directing: Grant). Sheridan commanded the cavalry under Hancock (subordinate context).

Grade C under rule 2; echelon unknown. responsibility_unresolved
Other candidates: Kershaw, Wilcox
Single CWSAC listing of Field. Humphreys says Wilcox's and Kershaw's divisions held the Bailey's Creek line when the movement began (July 27), Heth's joined them on the 27th, Kershaw attacked Sheridan's cavalry, and Field's division united with them only on the 29th. No inspected passage names who commanded the Confederate forces north of the James at first combat, so the listing stands, but the inspected record puts Field's division off the field then (rule 2, grade C). Kershaw and Wilcox, passage-only, are candidates.

supportedunresolved Hancock says success depended on the enemy's works being thinly held and the movement a surprise, and that during the night of the 27th he learned the enemy were reinforcing from south of the James.

2f0501f4827e…outcome
disputedpost_outcome The frozen and live results read Confederate victory; NPS says the Union turning efforts were abandoned when the Confederates reinforced and counterattacked. Hancock reports four 20-pounder Parrotts taken on the 27th and nearly 200 prisoners on the 28th; Humphreys says the expedition reduced the Petersburg garrison to three infantry divisions and drew two of three cavalry divisions north.
Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The diversion's effect on July 30 is campaign contribution, not this record's result.

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 reads 'Corps' and the live field zero. Hancock names Gibbon's, Barlow's and Mott's divisions with Sheridan's cavalry, adds Birge's brigade of a little over 2,500, and relays Grant's information of seven enemy brigades and a little cavalry in his front. Humphreys says Wilcox's and Kershaw's divisions held the line, Heth's joined on the 27th, and Field's and Fitzhugh Lee's divisions on the 29th.
Formation lists and one brigade figure; no return for either force. None is adopted as a matched opening strength; live zeros are not measured absence.

The creek and the Confederate works predate the Union crossing. No map verification.

fbc0249868bc…Open questions
- Sheridan's, Barlow's and Miles's reports (Nos. 20-21), Foster's report, Field's and Kershaw's reports, the Second Corps casualty list (blank in OCR) and Sheridan's 1866 report passage (Volume XXXVI; not re-selected) remain deferred.
- NPS/CWSAC (the live NPS page and the frozen Arnold rows) is one family. Humphreys' The Virginia Campaign of ’64 and ’65 (1883) is an interested history by the Army of the Potomac's chief of staff, later commander of its Second Corps, in the same author family as the registered From Gettysburg to the Rapidan; it relies on Meade's, Hancock's, Warren's, Burnside's, Parke's and Wilson's reports and quotes Lee's, Beauregard's and Gordon's despatches, so it is not independent of those families. Gillmore's, Meade's, Hancock's, Burnside's, Wilson's, Hampton's, Stannard's and Lee's papers, printed in Official Records Series I, Volumes XXXVI (Part 2), XL, XLII and XLVI (Part 1), are separate families of interested commanders' accounts; each volume is a shared container, not an additional witness. Lee's telegrams largely relay subordinates' reports. 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.
