Fort Davidson MO021
1864-09-27 to 1864-09-27 · MO · Price's Missouri Expedition [September-October 1864] · frozen result: Union · NPS summary (as listed)
In September 1864, a Confederate army under Maj. Gen. Sterling Price crossed into Missouri with the goal of capturing St. Louis. Union Brig. Gen. Thomas Ewing moved with reinforcements down the railroad to Ironton to retard Price's advance. On the morning of September 27, the Confederates attacked, driving the Federals back into their defenses anchored by Fort Davidson. In the late afternoon, Price unsuccessfully assaulted the fort repeatedly, suffering heavy casualties. Price, considering the possible time involved, had dismissed the possibility of mounting guns on the high ground to compel the fort to surrender or to shell the garrison into submission. During the night, the Federals evacuated the fort. Price had paid a high price in lives and gave Union forces the necessary time to concentrate and oppose his raid.
Command responsibility (ledger v2)
US: Thomas Ewing Jr.
Grade A under rule 2; echelon detachment_or_post. superior_directing
Rule 2. Britton says Ewing arrived and 'assumed command of the Federal forces at Pilot Knob' on the 26th, before the fighting of the 27th, and directed the defence and the evacuation. Rosecrans, commanding the department, directed Ewing to take a brigade to the Iron Mountain Railroad and concentrate the troops there, and Ewing 'was instructed to hold Pilot Knob if practicable' (superior_directing: Rosecrans; he directed from St. Louis, not on the field, so this is borderline). Nothing contradicts the listing.

information
disputedunresolved Price says information he believed reliable led him to expect the place could be taken without great loss, and that it proved totally incorrect. Britton says Price's engineer Mackey advised bombardment from Shepherd's Mountain and Price concurred, but that a council of war chose an immediate assault because it was reported among Confederate officers that much of the garrison was colored soldiers and some officers wished to avenge Ewing's removal of Southern families; he also says Ewing learned from prisoners that evening that Price was present with two divisions. The frozen and NPS description instead says Price, considering the time involved, had dismissed mounting guns on the high ground to compel surrender or shell the garrison.
Attributed knowledge and reasons from an interested report, a history and a summary; no message log inspected. The two accounts of why bombardment was not used differ, and neither is adopted.

Stores removed before and captured after the action; no supply or ammunition return for either side.

Britton gives Ewing's report of 200 killed, wounded and missing over the defence of the passes and the retreat to Leasburg, Ewing's estimate of 1,500 Confederate killed and wounded, and Mackey's statement of 1,164 lost in twenty minutes and not less than 1,500 in all; he says Price never reported his casualties. Price gives no figure for Fagan's division and 14 officers and 80 men killed and wounded in Marmaduke's, a figure that follows his account of the pursuit.

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 Garrison and Army of Missouri; the live field reads zero. Price entered Missouri on September 19 with nearly 12,000 men, 8,000 of them armed, and fourteen guns, and reported that information at Fredericktown put the enemy at Ironton at about 1,500; he attacked with Fagan's and Marmaduke's divisions while Shelby's was detached. Britton gives Ewing's force as 489 recently organized infantry plus 562 men of experienced units, 1,051 in all, with about 100 armed citizens and a company of Black men, and says about 5,600 men made the assault.
An army-wide figure eight days earlier, a pre-battle intelligence estimate and a history's counts; no matched return at the assault. None is adopted as a matched opening strength. The live zero is not measured absence.

supportedunresolved Britton describes Fort Davidson as an irregular hexagonal work with a ditch ten feet wide and six feet four inches deep, overlooked from Shepherd's Mountain and Pilot Knob, which engineers had judged indefensible against a force with good batteries; Ewing added two rifle-pits and cleared the nearest hillsides. Price says Shepherd's Mountain completely commanded the fortifications and that Marmaduke placed artillery there.
Ground and works described by a history and an interested report; no map verification. The fort predates Ewing's arrival but he added works, so the phase is left unresolved.

- Ewing's report (No. 55) and the Fort Davidson subordinate reports, Shelby's and Clark's reports, Mackey's 1896 article, and the Iron County terrain against a map remain deferred.
- Rosecrans's, Pleasonton's and Curtis's reports, the subordinate Union and Confederate reports in Volume XLI Part 1, the organization of Price's army (No. 89), Maclean's itinerary (No. 90), the Price Court of Inquiry, Hinton's 1865 Rebel Invasion of Missouri and Kansas, maps and returns remain deferred.
- NPS/CWSAC is one family (the NPS battle page plus the frozen Arnold rows). Wiley Britton's The Civil War on the Border, volume II (Putnam, 1899) is a retrospective history by a Union participant; by its preface the larger operations are based mainly on the published official reports, so it is not independent of the Price report family. Price's September 19 and November 2 dispatches and his December 28, 1864 report (Official Records Series I, Volume XLI, Part 1, No. 88) 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.
- No automatic commander attribution, causal campaign score, morale/readiness number or battle/campaign double counting.
