Fredericksburg I VA028

1862-12-11 to 1862-12-15 · VA · Fredericksburg Campaign [November-December 1862] · frozen result: Confederate · NPS summary (as listed)

CWSAC description
On November 14, Burnside, now in command of the Army of the Potomac, sent a corps to occupy the vicinity of Falmouth near Fredericksburg. The rest of the army soon followed. Lee reacted by entrenching his army on the heights behind the town. On December 11, Union engineers laid five pontoon bridges across the Rappahannock under fire. On the 12th, the Federal army crossed over, and on December 13, Burnside mounted a series of futile frontal assaults on Prospect Hill and Marye's Heights that resulted in staggering casualties. Meade's division, on the Union left flank, briefly penetrated Jackson's line but was driven back by a counterattack. Union generals C. Feger Jackson and George Bayard, and Confederate generals Thomas R.R. Cobb and Maxey Gregg were killed. On December 15, Burnside called off the offensive and recrossed the river, ending the campaign. Burnside initiated a new offensive in January 1863, which quickly bogged down in the winter mud. The abortive "Mud March" and other failures led to Burnside's replacement by Maj. Gen. Joseph Hooker in January 1863.

information

supportedunresolved Palfrey says Burnside's language makes his expectations hard to determine but that he seems to have expected Franklin's movement to strike the extreme Confederate right, and that if so he was wrong, since Confederate artillery and infantry were on Franklin's left; Palfrey also reads Franklin's en potence dispositions, made under Burnside's directions, as evidence Burnside was not confident of that. Fog on the morning of December 11 kept the Union artillery from firing accurately enough to drive away the sharpshooters.

Palfrey's inference about Burnside's expectation, from Burnside's report and orders; not an inspected original.

he expected that Franklin's movement upon the heights near Hamilton's would be a movement upon the extreme right of the Confederates.

logistics

supportedunresolved Palfrey says the promised pontoons arrived November 25, eight days after Sumner reached the river; on December 11 Confederate sharpshooters drove away the working parties at an upper and the middle bridge, while one lower bridge was laid without much opposition; the bridges were finished after troops were sent over in pontoons. NPS says five bridges were laid under fire.

Bridging delay and a contested crossing from summaries; no inspected engineer or transport record. The pontoon delay (to November 25) precedes the frozen interval; the contested December 11 crossing lies inside it, so the combined claim is not tagged inherited.

The promised pontoons did not arrive till the 25th, eight davs after Sumner reached the river".

objectives

supportedunresolved Palfrey says Burnside's plan depended on occupying Fredericksburg quickly and then moving directly on Richmond; NPS describes the December 13 frontal assaults on Prospect Hill and Marye's Heights.

Attributed plan and summarized execution; no inspected orders.

General Burnside's whole plan was based upon the expec- tation of an immediate occupation of Fredericksburg.

outcome

supportedpost_outcome The frozen result remains Confederate victory. NPS says Burnside called off the offensive and recrossed on December 15; Palfrey says the army was withdrawn across the river on Monday night in wind and rain.

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 17,929 total (US 13,353; CS 4,576); the live NPS field reads 17900 total (US 12600; CS 5300;). Palfrey prints Burnside's reported losses by grand division, totalling 1,180 killed, 9,028 wounded and 2,145 missing (which sum to 12,353), and Confederate losses of 1,894 for Longstreet's corps over five days and 3,415 for Jackson's.

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 sum of Palfrey's Union columns is computed here, not printed; Longstreet's figure spans five days. The OCR cell for the Right Grand Division's wounded is corrupt ('S, 933'); the printed wounded total of 9,028 fits only a reading of 3,933. The frozen US 13,353 and the computed 12,353 differ by exactly 1,000, which nothing inspected explains; the difference stays unreconciled.

responsibility

supportedunresolved Palfrey says Burnside's language in his orders to Franklin and in his report is so obscure that his expectations are hard to determine, and that no word of disapproval was sent from Burnside to Franklin for six or seven hours. He says Hancock's formation was prescribed in his orders.

Palfrey's interpretation of orders he summarizes; neither the orders nor Hardie's despatches were inspected. No listed commander receives automatic sole credit. The live heading ranks Lee Major General against the frozen General; the heading is not adopted.

supportedpost_outcome Palfrey, following Swinton's account, says Burnside's chief commanders urged him at the end of the day to recross the Rappahannock, and that he instead proposed to renew the attack the next day by storming the heights in person with a column of eighteen regiments of the Ninth Corps; Palfrey says the wiser counsels of Burnside's chief officers prevailed and the attack was not made.

The retained selection begins mid-sentence ('also says that'); the subject 'Swinton' lies immediately before the range in the pinned parent OCR (p.188), and whether the proposal sentence continues Swinton or is Palfrey's narration is not explicit. Swinton was not separately inspected. The proposal falls on the evening of December 13, inside the frozen December 11–15 interval; `post_outcome` here means after the December 13 assaults, not after the recorded engagement. Not an estimated effect.

strength

unknownunresolved

No inspected return establishes matched personnel at a common opening boundary. Imported numerical estimates remain unchanged; this pass does not validate them as simultaneous opening forces.

disputedunresolved The frozen force field reads 172,504 total (US 100,007; CS 72,497). The live NPS field reads 100007 total (US 0; CS 100007;), assigning the Union figure to the Confederate side. Palfrey says that, according to Burnside's report, Sumner's, Franklin's and Hooker's morning reports of December 13 showed about 113,000 men present for duty, either across the river or able to cross; that Lee's morning report showed upward of 78,000 present for duty on December 10; and that the army's present for duty on November 10 'is said to have been' 127,574.

Frozen, live and reported present-for-duty figures differ in scope and date; the live side assignment is not adopted. None is a matched opening population; present-for-duty is not engaged strength.

terrain

supportedunresolved Palfrey describes a shoulder-high stone wall with earth piled against it along the road below Marye's, forming a nearly perfect infantry parapet with guns and sharpshooters firing over it; he calls the Confederate position strong by nature and strengthened by art. NPS says Lee entrenched on the heights behind the town.

Position and works description; no map verification or numerical terrain effect. Palfrey describes the stone walls as existing estate and road boundaries and says earth was piled against the road wall without saying when or by whom; NPS places Lee's entrenching on the heights before the December 11 crossing in narrative order only, undated.

thus there was formed the most per- fect infantry parapet conceivable.
