Deep Bottom II VA071

1864-08-13 to 1864-08-20 · VA · Richmond-Petersburg Campaign [June 1864-March 1865] · frozen result: Confederate · NPS summary (as listed)

CWSAC description
During the night of August 13-14, the Union II Corps, X Corps, and Gregg's cavalry division, all under command of Maj. Gen. Winfield Scott Hancock, crossed James River at Deep Bottom to threaten Richmond, coordinating with a movement against the Weldon Railroad at Petersburg. On August 14, the X Corps closed on New Market Heights while the II Corps extended the Federal line to the right along Bailey's Creek. During the night, the X Corps was moved to the far right flank of the Union line near Fussell's Mill. On August 16, Union assaults near Fussell's Mill were initially successful, but Confederate counterattacks drove the Federals out of a line of captured works. Heavy fighting continued throughout the remainder of the day. Confederate general John Chambliss was killed during cavalry fighting on Charles City Road. After continual skirmishing, the Federals returned to the southside of the James on the 20th, maintaining their 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, X Corps and Gregg's division 'all under command of' Hancock. Humphreys says Grant sent Hancock north of the James and kept him there, directed not to assault the works (superior_directing: Grant). Birney commanded the X Corps under Hancock (subordinate context).

Confederate: Robert E. Lee

Grade C under rule 3b; echelon army. responsibility_unresolved

Other candidates: Charles Field

Lee (General) and Field (Major General) are listed. Humphreys has Field's division in the Bailey's Creek intrenchments when Hancock advanced on August 14 and Wilcox joining Field, which puts Field's division at the first combat but does not say who commanded the side's engaged forces. Lee's dispatches from Chaffin's Bluff on the 16th and 18th speak of 'our line' north of the James, but none is dated to the first combat. Neither listed officer is shown in command when the fighting began, so the senior listed officer is used (rule 3(b)). Field is a candidate. The live rank is not adopted.

information

supportedunresolved Humphreys says Grant acted on information that Lee had detached three infantry and one cavalry division, that the movement was concealed to suggest troops bound for Washington, and that the information proved erroneous.

Attributed knowledge from an interested history.

Information received from various sources leading General Grant to believe that General Lee had detached three divi¬ sions of infantry and one of cavalry

logistics

supportedunresolved Humphreys says the steamers carrying the Second Corps were unsuited to troops, could not run close in the shoal water on an ebbing tide, and delayed disembarkation until nine o'clock on August 14.

supportedunresolved Humphreys says Hancock was sent to threaten Richmond to prevent further detachments by Lee and, if possible, draw back those sent, with Gregg to dash on Richmond or destroy the railroads if the chance offered.

outcome

supportedpost_outcome The frozen and live results read Confederate victory. Lee reported that the enemy broke through on August 16 but was repulsed and the original positions reoccupied; Humphreys says Terry's attack carried the works with prisoners but the enemy soon retook them, leaving Birney only the picket line, and that the command withdrew on the night of the 20th.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit.

disputedpost_outcome The frozen casualty text reads 4,600 total and the live field 4,200 (US 2,900; CS 1,300). Humphreys gives the nominal-list casualties as 321 killed, 1,840 wounded and 625 missing (2,786), against Badeau's table of 1,498 killed and wounded and 515 missing (2,013), and found no Confederate statement; Lee's August 16, 8.30 p.m. dispatch calls that day's loss small.

responsibility

supportedunresolved Humphreys relays Hancock's criticism that Barlow assaulted with only one brigade instead of two divisions, says Birney's wide circuit delayed his attack until the 16th, and that Hancock was kept north of the James though directed not to assault the works. The frozen commanders are Lee and Field (CS) and Hancock (US); the live page lists Hancock and 'Major General Robert Lee'.

Criticism attributed as stated; Lee's and Field's roles are not described in the inspected passages beyond Lee's reports. The live rank is not adopted. 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. Humphreys gives the effective infantry of the Army of the Potomac at this time as 33,684 and of the Army of the James as 18,449, and says Field's division held the Bailey's Creek line with Wilcox's joining and Mahone's division and Hampton's and W. H. F. Lee's cavalry sent to reinforce them; the only division actually sent to Early was Kershaw's.

Army-wide effective infantry, not the force north of the James; the Confederate side is by formations only. None is adopted as a matched opening strength; live zeros are not measured absence.

terrain

supportedunresolved Humphreys says Barlow's line stretched nearly a mile and a half through thick woods toward Fussell's mill and that the wooded country prevented Hancock's personal examination; Lee says the Union right was found strongly intrenched on August 18.

Woods predate the operation; the works on both sides were built during it. No map verification.
