Champion Hill MS009
1863-05-16 to 1863-05-16 · MS · Grant's Operations Against Vicksburg [March-July 1863] · frozen result: Union · NPS summary (as listed)
Following the Union occupation of Jackson, Mississippi, both Confederate and Federal forces made plans for future operations. Gen. Joseph E. Johnston retreated, with most of his army, up the Canton Road, but he ordered Lt. Gen. John C. Pemberton, commanding about 23,000 men, to leave Edwards Station and attack the Federals at Clinton. Pemberton and his generals felt that Johnston's plan was dangerous and decided instead to attack the Union supply trains moving from Grand Gulf to Raymond. On May 16, though, Pemberton received another order from Johnston repeating his former directions. Pemberton had already started after the supply trains and was on the Raymond-Edwards Road with his rear at the crossroads one-third mile south of the crest of Champion Hill. Thus, when he ordered a countermarch, his rear, including his many supply wagons, became the advance of his force. On May 16, 1863, about 7:00 am, the Union forces engaged the Confederates and the Battle of Champion Hill began. Pemberton's force drew up into a defensive line along a crest of a ridge overlooking Jackson Creek. Pemberton was unaware that one Union column was moving along the Jackson Road against his unprotected left flank. For protection, Pemberton posted Brig. Gen. Stephen D. Lee's men atop Champion Hill where they could watch for the reported Union column moving to the crossroads. Lee spotted the Union troops and they soon saw him. If this force was not stopped, it would cut the Rebels off from their Vicksburg base. Pemberton received warning of the Union movement and sent troops to his left flank. Union forces at the Champion House moved into action and emplaced artillery to begin firing. When Grant arrived at Champion Hill, around 10:00 am, he ordered the attack to begin. By 11:30 am, Union forces had reached the Confederate main line and about 1:00 pm, they took the crest while the Rebels retired in disorder. The Federals swept forward, capturing the crossroads and closing the Jackson Road escape route. One of Pemberton's divisions (Bowen's) then counterattacked, pushing the Federals back beyond the Champion Hill crest before their surge came to a halt. Grant then counterattacked, committing forces that had just arrived from Clinton by way of Bolton. Pemberton's men could not stand up to this assault, so he ordered his men from the field to the one escape route still open: the Raymond Road crossing of Bakers Creek. Brig. Gen. Lloyd Tilghman's brigade formed the rearguard, and they held at all costs, including the loss of Tilghman. In the late afternoon, Union troops seized the Bakers Creek Bridge, and by midnight, they occupied Edwards. The Confederates were in full retreat towards Vicksburg. If the Union forces caught these Rebels, they would destroy them.

information
supportedunresolved The NPS summary says Pemberton was unaware that a Union column was moving along the Jackson Road against his unprotected left flank, while also saying he posted Lee to watch for 'the reported Union column'; it then reports that Lee and the Union troops sighted each other and that Pemberton received warning and sent troops to his left flank.
The summary does not reconcile 'unaware' with 'the reported Union column' or give times for these steps; keep the sequence unresolved rather than infer what Pemberton knew when. No information-quality score is implied.

This is a candidate pre-engagement decision, not an inherited disadvantage. The source attributes it jointly to Pemberton and his generals, so the commander_created tag does not give Pemberton sole credit.

952b5d08402a…objectives
supportedinherited Johnston ordered Pemberton to attack the Federals at Clinton.
The NPS summary reports Johnston's order, placed after the Union occupation of Jackson but otherwise undated, and a further order from Johnston repeating those directions, which Pemberton received on May 16. Both are retrospective NPS paraphrases, not the correspondence (see open question 1). Inherited is a hypothesis relative to Pemberton; Johnston is not a listed MS009 commander.

responsibility
supportedunresolved The NPS summary attributes the countermarch and the order withdrawing his men from the field to Pemberton, and the order to begin the attack (on his arrival around 10:00 am) and the later counterattack with forces just arrived from Clinton to Grant; it names Bowen's division's counterattack and Tilghman's rearguard as subordinate actions.
Attribution of orders as narrated in one retrospective summary; it does not apportion credit or blame, and no action is automatically credited to both listed commanders. Clock times are the source's approximate labels.
Thus, when he ordered a countermarch, his rear, including his many supply wagons, became the advance of his force.arnold-cwsac-battles, battle MS009; column description · snapshot

supportedunresolved The NPS narrative reports Pemberton commanding about 23,000 men at the time of Johnston's order; the structured MS009 force descriptions name formations without numbers.
A force under command when the order was issued, not personnel engaged, and not tied by the source to the Department of Mississippi and East Louisiana named in the force row; it is not automatically promoted. arnold-cwsac-forces MS009/Confederate and MS009/US have blank strength_min and strength_max, and the arnold-cwsac-battles strength cell is blank; blank cells cannot be quoted, so this absence is recorded as an inspected observation. No Union figure is given.

supportedunresolved The NPS summary places Pemberton's defensive line along a ridge crest overlooking Jackson Creek, with Lee's men atop Champion Hill as a lookout, and gives the Raymond Road crossing of Bakers Creek as the one escape route still open during the withdrawal.
Qualitative terrain from one retrospective NPS summary; no elevations, distances (other than the rear's position) or assessment of advantage. Phase is unresolved because the boundaries are unset.
