Grimball's Landing SC006

disputedunresolved Gillmore says the demonstration drew a large part of the Morris Island garrison to James Island; Jones says Gillmore believed this but was mistaken, since no troops could be drawn from Morris Island. Jones says the Union party at Grimball's was smaller than supposed.

Contested claims about what the demonstration achieved. No original reconnaissance, order or message chain was inspected to establish contemporary knowledge. Surprise in a summary does not independently establish what each commander knew.

No battle-specific supply, ammunition or transport return was inspected. Retrospective descriptions are not readiness measures.

supportedunresolved Terry's force was to make a strong demonstration on James Island without needlessly hazarding his command, to keep reinforcements from Morris Island. Jones says the Confederate movement was limited to driving in the pickets, reconnoitring, capturing the party at Grimball's and crippling the gunboats.

Stated aims from Gillmore's orders and a history.

disputedpost_outcome The frozen result reads Inconclusive and the live result Indecisive. Gillmore says the enemy was repulsed and Terry's command withdrawn on the 17th, its purpose accomplished; Jones says the Confederates retired with their object accomplished and that Terry abandoned the island that night, which was the desired result.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit.

disputedpost_outcome The frozen casualty text reads Total unknown (US unknown; CS 18); the live field reads 64 (US 46; CS 18). Jones gives the loss as about fifty Federal and eighteen Confederate.

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 Jones says Hagood commanded the Confederates on James Island and he and Colquitt led the reconnaissance in person, and that Terry signalled the gunboats to sweep the ground and withdrew that night; Gillmore credits the Pawnee and two armed transports with the repulse. The frozen commanders are Brigadier Generals Alfred H. Terry (US) and Johnson Hagood (CS).

Command roles from an interested report and a history; neither listed commander receives automatic sole credit.

No inspected return establishes matched personnel at a common opening boundary. Imported numerical estimates remain unchanged; this pass does not validate them as simultaneous opening forces.

disputedunresolved The frozen force text and the live page read 6,800 total (US 3,800; CS 3,000). Gillmore gives Terry's command as about 3,800 men and says Terry was attacked by a largely superior force. Jones says Terry had a larger force than the Confederates on James Island, gives Colquitt's column as about fourteen hundred, Way's as about eight hundred and Radcliffe's as about four hundred, and earlier says Terry outnumbered all of Beauregard's infantry in South Carolina.

Gillmore's 3,800 matches the frozen US figure; the Confederate column figures are Jones's and sum to about 2,600, not an inspected total. Gillmore and Jones disagree on which side was larger. None is adopted as a matched opening strength.

supportedunresolved Jones says the Confederate columns had to cross the marsh dividing Legare's from Grimball's, and that gunboats in the Stono and armed steamers in Folly River swept the ground in front; NPS says the attack was aborted because of incomplete reconnaissance of the difficult, marshy ground.
