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)

CWSAC description
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).

Confederate: Charles Field

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.

information

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.

Attributed knowledge from an interested report.

The suc¬ cess of this movement depended upon the contingency that the enemy’s works would be thinly occupied, and the movement a surprise.

logistics

supportedunresolved Humphreys says two ponton bridges spanned the James at Deep Bottom; Hancock says Butler's pickets lit fires along the night road and that gunboat fire was directed on the enemy by signals.

objectives

supportedunresolved Humphreys says the cavalry was to dash on Richmond if favorable or else destroy the railroads to the Anna rivers, the chief object, and that Grant thought the movement might weaken the Petersburg lines enough for the mine assault; Hancock says he was to hold a position to stop the enemy crossing troops north of the James.

Stated aims from an interested history and report.

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.

responsibility

supportedunresolved Hancock says he decided, with Sheridan and Meade's approval, to cross at the lower bridge and turn the position, and that Grant did not want the works assaulted; Humphreys credits Sheridan's dismounted troopers with repulsing Kershaw's attack. The frozen commanders are Major General Hancock (US) and Major General Field (CS); the live page matches.

Direction attributed as stated; Field's role is not described in the inspected passages. No listed commander receives 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 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.

terrain

supportedinherited Hancock says the enemy's works behind Bailey's Creek offered great advantages, the creek hard to cross under fire and about 1,000 yards of open ground before the works; Humphreys says the line ran from the mouth to Fussell's mill with the left refused.

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