Fort Bisland LA006

supportedunresolved Irwin says the Union concentration was almost completely masked from the Confederates and that Banks expected no word from Grover for nearly two days; Taylor sent Green forward to ascertain the enemy's strength. Taylor says he learned about 9 p.m. on April 13 from Reily that the enemy had landed in force at Hudgins' Point; Irwin gives the same hour.

Attributed knowledge from a history and an interested report; no dispatches inspected.

supportedunresolved Taylor ordered the wagons with quartermaster, commissary, medical and ordnance stores started for Franklin before the evacuation and abandoned a 24-pounder siege gun and a disabled howitzer. Irwin says Grover's embarkation of guns and horses caused great trouble and delay, and that two Union batteries' ammunition was giving out on April 13.

Supply statements from an interested report and a history; not returns.

supportedunresolved Irwin says Banks's purpose was to hold the Confederates where they stood until Grover gained their rear, and that Grover was to land on Grand Lake and cut off Taylor's retreat or attack him in rear. Taylor planned a dawn attack down the west bank with the Diana to force the landing force's recall.

Stated aims from a history and an interested report.

disputedpost_outcome The frozen result reads Union victory and the live result Union Victory. Taylor says the enemy had gained no ground by the close of April 13 and that he evacuated because of the landing in his rear; Irwin and NPS say the Union skirmishers found the works abandoned the next morning.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The position was given up for the turning movement, not taken by assault.

disputedpost_outcome The frozen casualty text reads Total 684 (US 234; CS 450); the live field reads 674 total (US 224; CS 450). Irwin gives the corps' loss as 3 officers and 37 men killed and 8 officers and 176 men wounded (224), and says the Confederate losses were never reported. Taylor says he could not yet estimate his loss; the Diana lost 2 killed and 5 wounded.

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. Irwin's 224 matches the live Union figure, not the frozen 234.

supportedunresolved Taylor says Sibley's delay and refusal frustrated his planned attack and credits Mouton with the defense of the east bank. Irwin says Banks gave discretionary orders for an assault, that Paine and Weitzel resolved to attack, and that Banks recalled the orders when news of Grover arrived. The frozen commanders are Major Generals Richard Taylor and Nathaniel P. Banks, as on the live page.

Command roles from an interested report and a history; the listed commanders do not receive automatic sole credit.

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 reads Banks's Department of the Gulf, XIX Army Corps [US] and District of Western Louisiana [CS]; the live field reads zero. Irwin says Banks had 10,000 men while Taylor reports 4,000 men with four batteries, estimated at 24 or 25 guns; he says Banks set out with seven brigades and fifty-six guns for the whole campaign. Taylor says at least 14,000 men and about sixty guns were displayed in his front on April 13 against his army of less than 4,000 at the start.

Figures from a history and an interested report; the Union figures differ, and Grover's division, detached to the lake, is inside the campaign total. None is adopted as a matched opening strength. The live zero is not measured absence.

supportedunresolved Irwin describes low breastworks across the neck of dry land on both banks of the Teche with their flanks on the swamps, the works partly commanded rather than commanding, the east-bank works only recently thrown up, and a cane field crossed by deep ditches in front. Taylor says his right rested on a swamp and his left on woods ending in a swamp.

Ground described by a history and an interested report; no map verification. The line predates the attack, but part of it was hastily completed, so the phase is left unresolved.
