Fort McAllister II GA028

1864-12-13 to 1864-12-13 · GA · Savannah Campaign [November-December 1864] · frozen result: Union · NPS summary (as listed)

CWSAC description
As Sherman' s troops approached Savannah they sorely required supplies. Sherman determined that if he could take Fort McAllister, supply ships could reach him. Thus, he ordered Maj. Gen. O.O. Howard, commander of his right wing, to take the fort. Howard chose Brig. Gen. William B. Hazen to accomplish the task. Hazen, in the afternoon of December 13, had his men in line for the attack. Upon giving the order to attack, his men rushed forward through the various obstacles prepared for them, entered the fort, and captured it. With his supply line open, Sherman could now prepare for the siege and capture of Savannah.

Command responsibility (ledger v2)

US: William B. Hazen

Grade A under rule 2; echelon division. superior_directing

Rule 2. Hazen's division was assigned the assault and Hazen chose its form and gave the order. Sherman ordered Howard to take the fort, and Sherman and Howard watched from the signal station and signalled orders to hasten (superior_directing: Sherman; Howard, the wing commander, is recorded here). Martin assumed command of the Second Brigade after its commander fell (subordinate).

Confederate: George A. Anderson

Grade B under rule 2; echelon detachment_or_post.

Rule 2, grade B. Cox puts the garrison of about two hundred men 'under command of Major G. W. Anderson'. His initials (G. W.) conflict with the listing's George A. Anderson. No listing field or passage identifies the two, and the ledger keeps conflicting initials separate (as with James B./James F. Fagan), so the passage is not taken as stating the listed officer's command. It establishes no different officer either, so the listing stands uncontradicted (as at GA002).

logistics

supportedunresolved Cox says Sherman's first task was to open communication with the fleet and establish a base of supplies, that bread was drawn from the trains and rice was nearly all the country furnished, and that the fort had about fifty days' rations. Hazen lists a month's supply of food among the captures and says his supply train had left Atlanta with 83 six-mule wagons. NPS says Sherman's troops sorely required supplies.

supportedunresolved Hazen was ordered to move down the right bank to Fort McAllister and capture it. Cox says the Ogeechee could not be used until the fort was taken; NPS says Sherman determined that taking the fort would let supply ships reach him.

outcome

supportedpost_outcome The frozen and live results read Union victory. Hazen says the bugle sounded at 5 o'clock and the fort was carried, the garrison fighting to their bomb-proofs; Cox says it was over in fifteen minutes.

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 205 (US 134; CS 71); the live field reads 384 (US 134; CS 250). Hazen and Cox both give Hazen's loss as 24 killed and 110 wounded. Hazen gives the captured garrison, including killed, as 250; Cox gives the garrison's loss as 48.

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. Hazen's 250 counts the whole garrison captured or killed, not casualties.

responsibility

supportedunresolved NPS says Sherman ordered Howard to take the fort and Howard chose Hazen. Cox says Hazen delayed the attack to use portions of each of his three brigades, over Colonel W. S. Jones's wish to attack at once, and that there was no formal surrender. Hazen says Martin took command of the Second Brigade when its commander fell. The frozen commanders are Brigadier General Hazen (US) and Major George A. Anderson (CS); Cox names 'Major G. W. Anderson'.

Direction is attributed as the sources state; Cox's initials for Anderson are not adopted. No listed commander receives automatic sole credit.

strength

unknownunresolved

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 reads the 2nd Division, XV Corps against the Fort McAllister garrison (120 men); the live field reads zeros. Hazen says his division had an effective strength of 4,426 on November 15 and that nine regiments were deployed for the assault; he gives the garrison, including killed, as 250. Cox says three regiments from each of the three brigades assaulted and puts the garrison at about 200 under Major G. W. Anderson.

Hazen's 4,426 is a division strength a month earlier; the garrison figures (120, about 200, 250 including killed) differ in source and basis. None is adopted as a matched opening strength; live zeros are not measured absence.

terrain

supportedinherited Cox describes a heavy earthwork commanding the river, with its gorge closed by an infantry line, the river planted with torpedoes and sub-terra shells along the land face, and the abatis not reaching below high-water mark. Hazen says the ground right of the fort was marshy and cut by deep streams, and that the assault passed torpedoes, abatis, ditches, palisading and parapet.

The fort and its obstacles predate the assault. Narrative descriptions.
