Fort Sanders TN025
1863-11-29 to 1863-11-29 · TN · Longstreet's Knoxville Campaign [November-December 1863] · frozen result: Union · NPS summary (as listed)
In attempting to take Knoxville, the Confederates decided that Fort Sanders was the only vulnerable place where they could penetrate Union Maj. Gen. Ambrose E. Burnside's fortifications, which enclosed the city, and successfully conclude the siege, already a week long. The fort surmounted an eminence just northwest of Knoxville. Northwest of the fort, the land dropped off abruptly. Confederate Lt. Gen. James Longstreet believed he could assemble a storming party, undetected at night, below the fortifications and, before dawn, overwhelm Fort Sanders by a coup de main. Following a brief artillery barrage directed at the fort's interior, three Rebel brigades charged. Union wire entanglements--telegraph wire stretched from one tree stump to another to another--delayed the attack, but the fort's outer ditch halted the Confederates. This ditch was twelve feet wide and from four to ten feet deep with vertical sides. The fort's exterior slope was almost vertical, also. Crossing the ditch was nearly impossible, especially under withering defensive fire from musketry and canister. Confederate officers did lead their men into the ditch, but, without scaling ladders, few emerged on the scarp side and a small number entered the fort to be wounded, killed, or captured. The attack lasted a short twenty minutes. Longstreet undertook his Knoxville expedition to divert Union troops from Chattanooga and to get away from Gen. Braxton Bragg, with whom he was engaged in a bitter feud. His failure to take Knoxville scuttled his purpose. This was the decisive battle of the Knoxville Campaign. This Confederate defeat, plus the loss of Chattanooga on November 25, put much of East Tennessee in the Union camp.

information
supportedunresolved Longstreet says so many reports led to the same conclusion that he determined he must attack (the reports' subject lies just outside the selected passage), and that approaching the fort he saw men straggling back. Burnside says a Confederate night advance that drove in the Union pickets led the defenders to expect an attack there, and that Lieutenant Benjamin roused the men early. NPS says Longstreet believed a storming party could assemble undetected at night.

Longstreet says his limited transport had brought no intrenching tools except his pioneers', and that picks and spades captured at Lenoir's were brought up on horseback.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. NPS's 'decisive' is a campaign judgment.

Burnside reported on November 30 about 300 prisoners, about 500 Confederate killed and wounded, 98 dead passed through his hands and his own loss about 20; his 1865 report says that such as could not retreat surrendered, 'in all, about 500', that the enemy's loss was certainly over 1,000 and his own 13. Longstreet says Colonel Ruff was killed at the ditch and that the bodies of Colonels McElroy and Thomas were afterward found in it.
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. Burnside's two reports differ from each other.

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.
disputedunresolved The frozen force field has unit names only; the live field reads zero. Burnside gives about 12,000 effective men in Knoxville, exclusive of new Tennessee recruits, against an enemy estimated at 20,000 to 23,000 including cavalry, and says the assaulting column was three brigades, reinforced by a second column. Longstreet says three of McLaws's brigades made the assault, with Anderson's brigade following, and earlier that the enemy had as many as he did in a strong fortified position.
Garrison, army and assault-column figures differ in scope; none is adopted. Live zeros are not measured absence.

supportedinherited Burnside says the fort was begun by the Confederates before the Federals entered East Tennessee and much improved by Poe's engineers, that abatis, chevaux-de-frise and wire entanglements were made where needed, and that traverses protected the garrison. NPS says the ditch was twelve feet wide and four to ten feet deep with vertical sides. Longstreet says the troops could not pass the ditch for want of ladders.
Inherited relative to the November 29 start; the works and siege-built entanglements may be commander-created under a campaign boundary and are not credited here. Longstreet's lack of ladders is Confederate preparation, not inherited ground. No map verification.
