1863-04-14 to 1863-04-14 · LA · Operations in West Louisiana [April 1863] · frozen result: Union · NPS summary (as listed)
While the other two Union XIX Army Corps divisions comprising the expedition into West Louisiana moved across Berwick Bay towards Fort Bisland, Brig. Gen. Cuvier Grover's division went up the Atchafalaya River into Grand Lake, intending to intercept a Confederate retreat from Fort Bisland or turn the enemy's position. On the morning of April 13, the division landed in the vicinity of Franklin and scattered Rebel troops attempting to stop them from disembarking. That night, Grover ordered the division to cross Bayou Teche and prepare for an attack towards Franklin at dawn. In the meantime, Confederate Maj. Gen. Richard Taylor had sent some men to meet Grover's threat. On the morning of the 14th, Taylor and his men were at Nerson's Woods, around a mile and a half above Franklin. As Grover's lead brigade marched out a few miles, it encountered Rebels on its right and began skirmishing with them. The fighting became intense; the Rebels attacked, forcing the Yankees to fall back. The gunboat Diana arrived and anchored the Confederate right flank. The Confederates were outnumbered, however, and, as Grover began making dispositions for an attack, they retreated leaving the field to the Union. This victory, along with the one at Fort Bisland, two days earlier, assured the success of the expedition into West Louisiana.
Command responsibility (ledger v2)
US: Cuvier Grover
Grade A under rule 2; echelon division.
Irwin has Grover march his division on Franklin at first light on the 14th, riding with Birge's leading brigade when the battle began, and sending in the 159th New York. Banks's instructions predate the operation and Banks was at Bisland, so no superior_directing is recorded (rule 2, grade A).

information
supportedunresolved Irwin says Grover knew nothing of Banks's movements, could not make out the enemy's force or position in the dark, and concluded from prisoners that he faced Taylor's whole force; his landing orders rested on misinformation. Taylor judged that the enemy meant to detain him until the column from below came up.

supportedunresolved Irwin says Grover's guns had to be landed over a bridge of flats and blames the excess artillery for the day and night lost and the hours of daylight spent landing guns that never fired. Taylor pressed his train through Franklin onto the cut-off road; the hospital boat with the sick and wounded fell into Union hands.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The Confederate escape is described as the object of the action.

d8f0c84409fa…disputedpost_outcome The frozen casualty text reads Total unknown (US 353; CS unknown); the live field reads 355 total (US 355; CS 0). Irwin gives Grover's reported loss for April 13, 14 and 17 as 353 and the nominal-list loss, headed as for the battle, as 6 officers and 43 men killed, 17 officers and 257 men wounded and 30 missing, also 353, which he says agrees with the three-day statement and which includes Dwight's losses of April 13 (3 killed, 9 wounded) and April 17 (1 killed, 5 wounded); the Confederate loss is not reported, but 21 dead and 35 wounded were left on the field.
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. Both 353 figures span April 13, 14 and 17 by Irwin's account and overlap LA008's April 17; neither is a battle-only total.

d8f0c84409fa…responsibility
supportedunresolved Irwin says Grover rode with Birge and sent in the 159th New York, that Taylor moved Gray to the left and attacked, and that Taylor then turned the command to Mouton and rode into Franklin; he calls Grover cautious by nature. Taylor blames Sibley's order for the capture of the Diana's crew. The frozen commanders are Major General Richard Taylor and Brigadier General Cuvier Grover, as on the live page.

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 reads 4th Division, XIX Army Corps [US] and five named Confederate units; the live field reads zero. Irwin puts Grover's whole force at about 5,000 of all arms, Birge's brigade at no more than 1,500 with a fighting line of perhaps 1,200, and says Taylor gives his infantry in the charge as less than 1,000; Grover had eighteen guns with four in action and Taylor four. Taylor says his charging force numbered less than 1,000 against four regiments, a battalion of cavalry and a battery, with a larger reserve concealed.
Figures from a history and an interested report for different parts of the field; Irwin's Confederate figure repeats Taylor. None is adopted as a matched opening strength. The live zero is not measured absence.

supportedunresolved Irwin says Birge marched with his right flank to the concealed Confederate line across the open fields of McKerrall's plantation, with the Teche on the left and a nearly impassable swamp on the right, and that the field was so contracted that Taylor could occupy its front. Taylor posted his line along the upper skirt of the woods fronting the field.
Ground described by a history and an interested report; no map verification. Taylor chose the position, so it is not tagged inherited.

- Grover's No. 24, Dwight's No. 30, Birge's No. 36 and the other Fourth Division reports, the nominal casualty lists, Mouton's No. 40 and Kirby Smith's No. 38 reports remain deferred.
- NPS/CWSAC is one family. Richard B. Irwin's History of the Nineteenth Army Corps (Putnam's, 1892), already registered for the Red River pass, is an interested Union history by Irwin, styled on the OCR title page assistant adjutant-general of the corps and of the Department of the Gulf. Its Teche chapters cite Taylor's report and the nominal lists, so it is not independent of them. Taylor's April 23, 1863 report (Official Records Series I, Volume XV, a shared container) is an interested Confederate account; it is placed in the group of his 1864 Red River reports as one author family. Report dates are not event times or proof of contemporary knowledge.
