Donaldsonville LA013

supportedunresolved Green says that until he came down he had no idea of the fort's position or strength, that his guides assured him the way past the stockade was open, and that Hardeman's and Lane's regiments were delayed by guide failures. Irwin says a signal from the fort warned the navy at ten minutes past midnight.

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

supportedunresolved Green says his men had no means to cross the inner ditch and fought with brickbats; he crossed the La Fourche on a bridge of sugar-coolers. Irwin says even the sick of the garrison took part in the defense.

Statements from an interested report and a history; not returns.

supportedunresolved On June 27 Green advised against storming and proposed to turn the fort from below to annoy the transports; on July 3 he says Mouton's order of the 26th was to take possession of the fort, whose capture would have troubled the army besieging Port Hudson. Irwin says Green was sent there to attack. NPS says Mouton ordered the brigades to take Donaldsonville and dates the order June 28.

Stated aims from an interested report, a history and a summary; Green's June 27 advice and the attack differ. The date of Mouton's order differs (Green's 'of the 26th ultimo'; NPS June 28) and is not reconciled.

disputedpost_outcome The frozen result reads Union victory; the live result reads Indecisive. Green says his men were not repulsed until they met the ditch; Irwin says the fight ended with the flag still flying over the fort; NPS says the point remained in 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 frozen and live result fields disagree.

disputedpost_outcome The frozen casualty text reads 324 total (US 23; CS 301), and the live field agrees. Green's statement totals 40 killed, 114 wounded and 107 missing (261), and he says he saved about 100 men by his flag of truce. Irwin repeats 261 but says 124 prisoners were counted on the gunboats and the garrison buried 69 Confederates and was still at it; the garrison lost 8 killed and 13 wounded (21) and the Princess Royal 1 killed and 2 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.

supportedunresolved Green says he set the plan and briefed each regimental commander, and that Colonel Major led the column enveloping the fort. Irwin says Major Bullen commanded the garrison, quotes his message to Emory, and notes criticism of Green's recklessness. The frozen commanders are Brigadier General Tom Green and Major Joseph D. Bullen, as on the live page.

Command roles from an interested report and a history; the Princess Royal's part is not separately attributed. 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 the Fort Butler garrison of two companies of the 28th Maine and convalescents [US] against Green's and Major's brigades [CS]; the live field reads zero. Green heard from citizens on June 27 that the fort held 300 to 500 men and five gunboats, and reported on July 3 a garrison of between 500 and a figure printed '000' in OCR, against his assaulting party of about 800. Irwin says the fort held a mixed force of 180 and that Green brought six regiments and a battery of 1,300 to 1,500; his footnote reads Green's 800 as the four regiments actually engaged and derives 1,811.

Figures for different scopes from an interested report and a history; the garrison figures disagree widely. None is adopted as a matched opening strength. The live zero is not measured absence.

supportedunresolved Green described an open approach of 900 yards and a ditch 16 feet wide and 12 deep, and says the assault on the river front failed at an inner ditch his guides had not told him of. Irwin describes a square redoubt in the angle of the bayou and the river with stockades to the water, and low water exposing wide margins of batture. NPS says the ditch was unknown to the attackers and too wide to cross.

Ground described by an interested report, a history and a summary; no map verification. The fort and ditch predate the attack, but their state on June 28 is described only by these accounts, so the phase is left unresolved.
