Iuka MS001

supportedunresolved Greene says the wind kept the firing from being heard, and that Rosecrans's midday message saying he was within eight miles (OCR '12. -10 p.m.'; the clock is not verified against print) reached Grant only after night. NPS says Ord later said he never heard any fighting and Grant remarked he had heard no sounds of battle.

Retrospective accounts of what commanders knew; no inspected message log or acoustic evidence.

supportedunresolved NPS says Rosecrans followed the single Jacinto road instead of two roads as directed; Greene says an after-midnight message from Rosecrans reported that, through a guide's fault, his march had been slightly delayed and one division was still at Jacinto, twenty miles from Iuka.

Movement constraints from summaries; no march table or transport record inspected.

supportedunresolved Greene says Grant's plan was to hold the Jacinto and Fulton roads and cut Price off against the Tennessee; NPS says Bragg had ordered Price to prevent Rosecrans reinforcing Buell's troops, and that Price was preparing to rendezvous with Van Dorn.

Attributed plans from summaries; no inspected orders.

supportedpost_outcome The frozen result is Union victory, with a note that it caused Grant concern about Rosecrans's abilities; the live field reads Union Victory. Both sources say Price escaped by the Fulton road.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The frozen note is a source annotation, not a measured effect.

disputedpost_outcome The frozen casualty text reads 1,482 total (US 782; CS 700); the live NPS field reads 1384 total (US 790; CS 594;). Greene gives Rosecrans's reported 782 and Price's reported 496, against a provost-marshal tally of 1,438 including prisoners and an estimate of wounded carried off.

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 provost-marshal total includes an estimate and prisoners; it is not adopted. Price's reported 86 killed and 408 wounded sum to 494 in the OCR against a printed total of 496; print was not checked.

disputedunresolved NPS says Rosecrans stated he left the Fulton road unguarded for fear of dividing his force, and that Grant approved; Greene says Rosecrans, forced into action on arriving, had no opportunity to move onto that road. Grant had ordered Ord to wait for the sound of fighting.

The sources give different reasons for the open road; neither is adopted. The listed commanders do not receive automatic sole credit for the combined operation.

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 `forces_text` describes approx. 4,000–4,500 US (2nd and cavalry divisions) and approx. 3,200 CS (1st Division). The frozen structured US bounds are 4,000/4,000 (the upper bound is not 4,500) and the CS bounds are 3,200/3,200; the live field reads zero. NPS says Price had about 14,000 men. Greene gives Rosecrans's column about 9,000 and Ord's about 6,000, says Hamilton brought 2,800 into action, and that two Confederate brigades of three to four thousand did the fighting.

Army, column, engaged-division and brigade figures are different populations; none is adopted as a matched opening strength. Ord's column did not engage. The imported model row uses the structured 4,000 point value; the text's 4,500 upper bound is not carried into it. This is recorded, not corrected.

supportedunresolved NPS says the Confederates were well placed in a ravine filled with timber and underbrush below the hill the Union column had climbed; Greene places Hamilton's division on a wooded knoll across the road fork.
