CWSAC description
After the Battle of Iuka, Maj. Gen. Sterling Price's Confederate Army of the West marched from Baldwyn to Ripley where it joined Maj. Gen. Earl Van Dorn's Army of West Tennessee. Van Dorn was senior officer and took command of the combined force numbering about 22,000 men. The Rebels marched to Pocahontas on October 1, and then moved southeast toward Corinth. They hoped to seize Corinth and then sweep into Middle Tennessee. Since the Siege of Corinth, in the spring, Union forces had erected various fortifications, an inner and intermediate line, to protect Corinth, an important transportation center. With the Confederate approach, the Federals, numbering about 23,000, occupied the outer line of fortifications and placed men in front of them. Van Dorn arrived within three miles of Corinth at 10:00 am on October 3, and moved into some fieldworks that the Confederates had erected for the siege of Corinth. The fighting began, and the Confederates steadily pushed the Yankees rearward. A gap occurred between two Union brigades which the Confederates exploited around 1:00 pm. The Union troops moved back in a futile effort to close the gap. Price then attacked and drove the Federals back further to their inner line. By evening, Van Dorn was sure that he could finish the Federals off during the next day. This confidence--combined with the heat, fatigue, and water shortages--persuaded him to cancel any further operations that day. Rosecrans regrouped his men in the fortifications to be ready for the attack to come the next morning. Van Dorn had planned to attack at daybreak, but Brig. Gen. Louis Hébert's sickness postponed it till 9:00 am. As the Confederates moved forward, Union artillery swept the field causing heavy casualties, but the Rebels continued on. They stormed Battery Powell and closed on Battery Robinett, where desperate hand-to-hand fighting ensued. A few Rebels fought their way into Corinth, but the Federals quickly drove them out. The Federals continued on, recapturing Battery Powell, and forcing Van Dorn into a general retreat. Rosecrans postponed any pursuit until the next day. As a result, Van Dorn was defeated, but not destroyed or captured, at Hatchie Bridge, Tennessee, on October 5.

Command responsibility (ledger v2)

US: William S. Rosecrans

Grade A under rule 2; echelon unknown.

Greene's October 1 return puts 23,000 under Rosecrans at Corinth before the October 3 fighting; the pursuit decision shows he still commanded at the end.

outcome

supportedpost_outcome The frozen result remains Union victory. Greene says the Confederates were in full retreat by noon on October 4, but later dates the battle to 'October 5th'.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. Greene's October 5 date conflicts with his own narrative and the frozen interval; the frozen dates are kept.

disputedpost_outcome The frozen casualty text reads 7,197 total (US 2,359; CS 4,838); the live NPS field reads 7150 total (US 2350; CS 4800;). Greene gives Rosecrans's reported 2,359 and official Confederate returns of 4,838, against Rosecrans's statement of 2,268 prisoners taken and his Medical Director's count of 1,423 Confederates buried, from which Greene infers a loss over nine thousand.

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. Greene's nine-thousand figure is an inference from an assumed wounded-to-killed ratio, not a count.

responsibility

supportedunresolved Both sources say Van Dorn took command as senior. NPS says Hébert's sickness postponed the October 4 attack to 9 a.m.; Greene says the plan miscarried 'in Van Dorn's opinion' owing to that delay, and that two eccentric Union advances opened the gap exploited on October 3.

Attributed judgments about subordinate conduct; no automatic sole credit to either listed army commander.

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 live NPS field reads 45000 total (US 23000; CS 22000;), matching the narrative. Greene gives Van Dorn about 22,000 in the field from a September 28 return (Price about 14,000, Lovell about 8,000) and Rosecrans 23,000 from Grant's October 1 return.

Figures come from returns on dates before the battle; effective and engaged scopes are not established. Agreement may reflect shared dependence on the returns and is not independent corroboration.

terrain

supportedinherited NPS says Union forces had built inner and intermediate lines since the spring siege; Greene describes redoubts near the town and an outer line of entrenchments about two miles out, built earlier by the Confederates.

Pre-existing works at the opening boundary, from summaries; no map or engineering record verified.
