Jerusalem Plank Road VA065

1864-06-21 to 1864-06-24 · VA · Richmond-Petersburg Campaign [June 1864-March 1865] · frozen result: Union · NPS summary (as listed)

CWSAC description
On June 21, the Union II Corps, supported by the VI Corps, attempted to cut the Weldon Railroad, one of the major supply lines into Petersburg. The movement was preceded by Wilson's cavalry division which began destroying tracks. On June 22, troops from Lt. Gen. A.P. Hill's corps led by Brig. Gen. William Mahone counterattacked, forcing the II Corps away from the railroad to positions on the Jerusalem Plank Road. Although the Federals were driven from their advanced positions, they were able to extend their siege lines farther to the west.

Command responsibility (ledger v2)

US: George G. Meade

Grade A under rule 3a; echelon army.

Other candidates: Ulysses S. Grant

Grant (Lieutenant General) and Meade (Major General) are listed. Humphreys has Meade instructing Birney's II Corps and Wright's VI Corps on the 21st, when Barlow's reconnaissance met the enemy, and ordering them to move irrespective of each other (rule 3(a)). No inspected passage shows Grant directing this operation, so no superior is recorded; NPS lists only Grant. Grant is a candidate.

Confederate: Robert E. Lee

Grade C under rule 2; echelon army. responsibility_unresolved

Other candidates: A.P. Hill

Single CWSAC listing. Lee's report from the headquarters of the Army of Northern Virginia says the enemy was driven back by Mahone 'with a portion of his command'; the description has Hill's troops led by Mahone. Mahone is subordinate context. Humphreys says 'General A. P. Hill had been sent down the Weldon Railroad to meet Meade's attempt upon it', with Wilcox's and Mahone's divisions, and describes Hill's flank attack of the 22nd; Hill is not listed. The side's first combat, on the 21st, is not attributed to any commander: 'a considerable force of the enemy moved down the road to meet' Barlow's reconnaissance. Lee's dispatch reports the fighting from army headquarters but does not state that he commanded the engaged force. Because Hill's command is not dated to the first combat, the listing is not strictly contradicted and stays, but the inspected sources disagree about who commanded (rule 2, grade C); Hill is a candidate. Alternative reading: if Hill's force is read as the force that met Barlow on the 21st, rule 2's third bullet would give Hill (cf. VA073). The live rank is not adopted. (Revised after the separate review, finding R2.)

outcome

disputedpost_outcome The frozen result reads 'Union gained ground' and the live result Union Victory, while the descriptions say the Second Corps was forced from the railroad but the siege lines were extended west. Lee says the enemy was driven from his first line to his second on June 22 and back from the railroad on June 23. Humphreys says the Second Corps re-established itself the next morning on the line it had been driven from, and the two armies stayed in that general position for some weeks.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The live 'Union Victory' and the frozen 'Union gained ground' are different categories; not reconciled.

disputedpost_outcome The frozen casualty text reads 4,000 total and the live field 3,534 (US 2,962; CS 572). Humphreys gives the Second Corps loss as about 1,700 prisoners, four guns and several colors, with killed and wounded not severe; Lee reports about 1,600 prisoners, 4 guns and 8 colors on June 22, about 600 prisoners on June 23, and, separately, his entire loss on the morning of June 24 as 97 killed and wounded and 209 missing, the morning on which he reports that part of one of Hoke's brigades entered the enemy's works; the inspected passages do not tie that action to Mahone's fights or establish that it belongs to this record.

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. The prisoner counts are captor and loser figures for overlapping populations. Lee's June 24 morning loss belongs to the Hoke attack he reports that day; it is not assigned to this record or added to its totals.

responsibility

supportedunresolved Humphreys says Meade instructed Birney and Wright, ordered them to move irrespective of each other after connection caused delays, and that Birney had not taken the requisite precautions to secure his left. Lee credits Mahone with the June 22 and 23 attacks. The frozen commanders are Grant and Meade (US) and Lee (CS); the live page lists Grant and 'Major General Robert Lee'.

Direction and criticism attributed as stated; 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 only 'Corps' and the live field zero. Humphreys names the Second Corps, followed by the Sixth, against Hill with Wilcox's and Mahone's divisions supported by B. R. Johnson's; Lee names Mahone with a part of his division.

Formations only; no headcount or return was inspected. None is adopted as a matched opening strength; live zeros are not measured absence.
