Chattanooga TN005
1862-06-07 to 1862-06-08 · TN · Confederate Heartland Offensive [June-October 1862] · frozen result: Union · NPS summary (as listed)
In late Spring 1862, the Confederacy split its forces in Tennessee into several small commands in an attempt to complicate Federal operations. The Union had to redistribute its forces to counter the Confederate command structure changes. Maj. Gen. Ormsby Mitchel received orders to go to Huntsville, Alabama, with his division to repair railroads in the area. Soon, he occupied more than 100 miles along the Nashville & Chattanooga and Memphis & Charleston railroads. In May, Mitchel and his men sparred with Maj. Gen. Edmund Kirby Smith's men. After Mitchel received command of all Federal troops between Nashville and Huntsville, on May 29, he ordered Brig. Gen. James Negley with a small division to lead an expedition to capture Chattanooga. This force arrived before Chattanooga on June 7. Negley ordered the 79th Pennsylvania Volunteers out to reconnoiter. It found the Confederates entrenched on the opposite side of the river along the banks and atop Cameron Hill. Negley brought up two artillery batteries to open fire on the Rebel troops and the town and sent infantry to the river bank to act as sharpshooters. The Union bombardment of Chattanooga continued throughout the 7th and until noon on the 8th. The Confederates replied, but it was uncoordinated since the undisciplined gunners were allowed to do as they wished. On June 10, Smith, who had arrived on the 8th, reported that Negley had withdrawn and the Confederate loss was minor. This attack on Chattanooga was a warning that Union troops could mount assaults when they wanted.

information
supportedunresolved NPS says Negley sent the 79th Pennsylvania to reconnoiter and it found the Confederates entrenched.
Summary of a reconnaissance result, not an inspected report or message chain. Confederate knowledge of Negley's approach remains uninspected. The reconnaissance may be commander-created, but no clock is established.

supportedunresolved NPS describes an uncoordinated Confederate artillery reply by undisciplined gunners; Cist quotes Duke that Leadbetter had two or three guns in battery.
Retrospective descriptions of guns and service, not an ordnance return or readiness score. Duke's quotation is part of Cist, not a separately inspected original.

An attributed counterfactual opinion, not a measured causal effect. No boat, bridge or ford inventory was inspected.

supportedunresolved NPS says Mitchel ordered an expedition to capture Chattanooga; Cist describes an expedition against the town that bombarded it and made a demonstration of crossing.
Stated mission versus executed action; no original order was inspected. Whether the demonstration reflected a changed objective is not established.

supportedpost_outcome The frozen result remains Union victory. Cist says Negley then withdrew and encamped at Shelbyville; NPS says Smith reported on June 10 that Negley had withdrawn.
Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The victory label is the source classification of a bombardment without a crossing.

b3ce0ebfaaaf…disputedpost_outcome The frozen casualty text reads 88 total (US 23; CS 65). The live NPS field reads 3 total (US 0; CS 3;).
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. Cist's Jasper losses belong to an earlier approach action and are not added.

952b5d08402a…responsibility
supportedunresolved Mitchel ordered the expedition and Negley commanded it. On the Confederate side, NPS says the listed commander, Kirby Smith, arrived on the 8th, and Cist quotes Duke naming Leadbetter as commandant of the place.
The frozen principal Confederate commander arrived during the two-day interval; local command and departmental authority are different roles, and neither receives automatic sole credit. Live heading ranks (Major General Negley; Lieutenant General Smith) conflict with the frozen ranks and are not adopted.

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 names only formation levels: Division [US]; Department [CS]. The live NPS field reads 0 total (US 0; CS 0;). Cist lists the expedition's components without a count.
No numerical strength is supplied by any inspected source. Live zeros are not measured absence; a component list does not establish matched opening populations.

b3ce0ebfaaaf…Open questions
- Original orders, returns, casualty reconciliation, Confederate knowledge of the approach and the effective local command clock remain deferred after the bounded pass. The June 7–8 interval excludes the earlier Jasper action.
- NPS/CWSAC is one family; Cist is one interested retrospective Union staff history. Quoted reports and participant accounts inside Cist are not additional independently inspected families.
- No automatic commander attribution, causal campaign score, morale/readiness number or battle/campaign double counting.
