information

supportedunresolved Sedgwick says Butterfield had repeatedly told him the force in front was very small, and that the chief of staff was misinformed. Early says he had started toward Chancellorsville under Lee's instructions on the 2nd, then turned back on information from the rear.

Attributed knowledge from the two opposing reports; no inspected message log.

logistics

supportedunresolved Sedgwick says his order to cross at Fredericksburg found his whole command south of the river, where no bridges had been laid at the town, so he moved by the flank on the Bowling Green road instead of recrossing. Early says part of Pendleton's artillery had been sent to the rear under instructions.

Movement statements from the two opposing reports; no inspected engineer or artillery record.

objectives

supportedunresolved Sedgwick says he was ordered to cross at Fredericksburg, move toward Chancellorsville, attack and destroy any force on the road, and be near Hooker at daylight. Early says Jackson told him to remain with his division and Barksdale's brigade to observe the enemy.

outcome

supportedpost_outcome The frozen and live results read Union victory. Sedgwick says the storming columns carried the works, capturing guns and many prisoners; Early says the trenches were carried and the hill taken, with much of the 18th and part of the 21st Mississippi and a company of the Washington Artillery captured; NPS says the Confederates withdrew and regrouped.

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

supportedpost_outcome The frozen casualty text reads 2,000 total; the live field reads zero. Sedgwick's 4,925 covers all Sixth Corps operations, and Early's division loss of 136 killed, 838 wounded and some 500 missing, most in all probability stragglers by his account, covers the whole period from the crossing, excluding Barksdale's brigade and the artillery.

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. Both report totals span Salem Church (VA033) and more; neither is assigned to this engagement.

responsibility

supportedunresolved Early says a flag of truce was received improperly by Colonel Griffin at the foot of Marye's Hill and that heavy columns advanced almost as soon as it returned. Sedgwick credits Colonel Burnham's leading of the Light Brigade against the rifle-pits. The frozen and live commanders are Sedgwick and Early, both Major Generals.

Judgments are attributed; the frozen commanders do not receive 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; the live field reads zero. NPS says the VI Corps, reinforced by Gibbon's division, assaulted outnumbered Confederates. Sedgwick says the enemy's works were occupied in considerable force; Early says Griffin's 18th and 21st Mississippi held the works at the foot of Marye's Hill, with the rest of Barksdale's infantry nearby.

No count is given for either side; none is adopted. Live zeros are not measured absence.

terrain

supportedunresolved NPS says the Confederates held entrenchments on Marye's Heights. Sedgwick says the rifle-pits and batteries on the heights repulsed his first assault, that a stream kept Howe from moving right and the canal checked Gibbon, so nothing remained but direct assault.
