Mobile Bay AL003
1864-08-02 to 1864-08-23 · AL · Operations in Mobile Bay [August 1864] · frozen result: Union · NPS summary (as listed)
A combined Union force initiated operations to close Mobile Bay to blockade running. Some Union forces landed on Dauphin Island and laid siege to Fort Gaines. On August 5, Farragut's Union fleet of eighteen ships entered Mobile Bay and received a devastating fire from Forts Gaines and Morgan and other points. After passing the forts, Farragut forced the Confederate naval forces, under Adm. Franklin Buchanan, to surrender, which effectively closed Mobile Bay. By August 23, Fort Morgan, the last big holdout, fell, shutting down the port. The city, however, remained uncaptured.
Command responsibility (ledger v2)
US: David G. Farragut
Grade C under rule 5; echelon flotilla. joint_command
Other candidates: Gordon Granger
Navy (Farragut) and army (Granger) listings. No passage shows one officer over both: Mahan describes an understanding between the admiral and Granger, 'in immediate command of the troops', and Canby's forces as co-operating. Rule 5, second case: the description credits Farragut's fleet, which forced Buchanan's squadron to surrender, with effectively closing Mobile Bay. Granger's troops landed first on Dauphin Island and invested Gaines, Fort Morgan fell on the 23rd to a joint bombardment of the siege batteries and the fleet (Mahan), and Page rejected a surrender demand signed by both; a reading of the whole interval as jointly compelled would give grade D. Farragut took charge in person (Mahan).

Navy (Buchanan, listed 'Admiral') and army (Page) listings. No passage shows one officer over both: Page commanded Fort Morgan, relieved Anderson at Gaines, and reported to Maury (not listed), while Buchanan commanded the naval forces and directed the ram's battery in person until wounded (Mahan). Rule 5, second case: the description ties the result to the surrender of the naval forces under Buchanan, which effectively closed the bay. Fort Morgan under Page held until the 23rd and ended the record, so a reading of the interval as jointly decided would give grade D.

6ee60469cc2c…outcome
disputedpost_outcome The frozen and live results read Union victory. NPS says that after passing the forts Farragut forced Buchanan's naval forces to surrender; Mahan says the United States flag was hoisted on board the Tennessee at ten o'clock. Mahan says Fort Powell was evacuated the night of the 5th, Gaines surrendered the day after the 6th, and Fort Morgan surrendered on the 23rd; Page says the Union flag rose over Gaines on the morning of the 8th and that he capitulated at 2 p.m. on the 23rd. NPS says the city remained uncaptured. The live page files the record under Burbridge's Raid into Southwest Virginia, which conflicts with the frozen campaign and is not adopted.
Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit.

Mahan gives the Tennessee's loss as 2 killed and 10 wounded and the Union fleet's as 52 killed and 170 wounded, says 21 of the Tecumseh's complement of over a hundred were saved, and gives the Selma's loss as five killed and ten wounded. Page says the fort's casualties were slight on August 5 and unusually small in the siege; his lists are marked not found.

6ee60469cc2c…responsibility
supportedunresolved Mahan says Farragut took charge in person and turned the Hartford past the Brooklyn over the torpedo line, and that Buchanan directed the ram's battery in person until wounded. Page says he rejected Farragut's and Granger's joint demand and condemned Anderson's surrender of Gaines. The frozen commanders are Admiral Franklin Buchanan, Brigadier General Richard L. Page, Rear Admiral David G. Farragut and Major General Gordon Granger; the live page lists Farragut as Admiral and misspells Buchanan.
Command roles from a history and an interested report; the listed commanders do not receive automatic sole credit, and the live rank is not adopted.

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 Farragut's fleet of 14 wooden ships and 4 monitors with army forces, against Buchanan's flotilla of three gunboats and an ironclad and the Morgan, Gaines and Powell garrisons; the live field reads zero. NPS says Farragut's fleet of eighteen ships entered the bay; Page says the fleet that moved up to pass Fort Morgan was twenty-three men-of-war, four of them monitors. Mahan lists four monitors in the starboard column and the wooden ships of the port column with their tonnage and guns, describes Buchanan's squadron as the ram Tennessee and three paddle-wheel gunboats, and says Granger had not men enough to attack both forts at once. Page gives his Fort Morgan garrison as some 400 effective during the siege.
Ship counts, an army limitation and one garrison figure for different phases; no matched return. None is adopted as a matched opening strength. The live zero is not measured absence.

supportedunresolved Mahan says the main ship channel skirted Mobile Point and narrowed to a little under two thousand yards, that Fort Morgan commanded it while Gaines was too distant to count for much, and that a triple line of torpedoes left an opening not much over one hundred yards from the beach for blockade-runners. Page says the fort's brick walls proved easily penetrable and that the enemy could fire on it from every point of the compass.
Ground and works described by a history and an interested report; no map verification. The works and obstructions predate the attack, but the phase is left unresolved.

- Granger's report (No. 4), Canby's dispatches (read, not selected), Maury's, Williams's, Buchanan's and the other army and naval reports in Volume XXXIX Part 1, Farragut's report in the Official Records of the Navies, and the prisoner counts for Forts Gaines and Morgan remain deferred.
- NPS/CWSAC is one family (the NPS battle page plus the frozen Arnold rows). A. T. Mahan's The Gulf and Inland Waters (Scribner, 1883; Project Gutenberg transcription of the 1898 London printing) is a retrospective naval history by a Union naval officer, registered earlier for other engagements; its Mobile Bay chapter compiles its times from the logs and reports and quotes Farragut and Buchanan, so it is not independent of the naval reports. Page's August 6-30, 1864 reports to Maury (Official Records Series I, Volume XXXIX, Part 1, No. 14) are one family of interested Confederate accounts. The Official Records volume is a shared container, not an additional witness. Report dates are not event times or proof of contemporary knowledge.
