Westport MO027

1864-10-23 to 1864-10-23 · MO · Price's Missouri Expedition [September-October 1864] · frozen result: Union · NPS summary (as listed)

CWSAC description
Maj. Gen. Sterling Price's Missouri Expedition had changed course from St. Louis and Jefferson City to Kansas City and Fort Leavenworth. As his army neared Kansas City, Maj. Gen. Samuel R. Curtis's Army of the Border blocked its way west, while Maj. Gen. Alfred Pleasonton's provisional cavalry division was closing on their rear. Price decided that he needed to deal with the two Union forces and decided to attack them one at a time. With Pleasonton still behind him, Price chose to strike Curtis at Westport first. Curtis had established strong defensive lines and during a four-hour battle, the Confederates hurled themselves at the Union forces but to no avail. The Rebels could not break the Union lines and retreated south. Westport was the decisive battle of Price's Missouri Expedition, and from this point on, the Rebels were in retreat.

Command responsibility (ledger v2)

US: Samuel R. Curtis

Grade A under rule 2; echelon army.

Rule 2. Curtis ordered the dawn attack of the 23rd and later 'came upon the field and ordered his entire line to advance' (Britton); the description credits Curtis's lines. Britton has the attacking force 'sent forward under General Blunt early that morning', and Blunt's brigades met Shelby before Curtis came to the front: Blunt led the engaged force at first combat under Curtis's orders. This is read as a subordinate leading the force, not a contradiction; a reviewer applying the KY007 pattern could read it otherwise (rule 2, grade C, Blunt). Nothing names another officer as commanding the Army of the Border.

Confederate: Sterling Price

Grade A under rule 2; echelon army.

Rule 2. The description has Price deciding to strike Curtis first; Price's report has Shelby attacking with two of Fagan's brigades (subordinate context) and Price forming the unarmed men himself. Nothing contradicts the listing.

Nested records

ContainingContainedOutcomeReason
Byram's Ford MO026Westport MO027not_nestedThe Byram's Ford description treats the Westport fight of the 23rd as a separate, simultaneous battle against Curtis's Army of the Border, and narrates only Pleasonton's assault on Marmaduke at the ford that day. The force scopes overlap (Blunt's division and Shelby's division, engaged at the Big Blue on the 22nd, fought at Westport on the 23rd), and the MO026 description also calls the ford 'a strategic point during the fighting around Westport'.

information

supportedunresolved Britton says Curtis's information led him to overestimate the Confederate strength and made him overcautious, and that on the night of the 22nd he learned Pleasonton had driven Price from Independence. Price says he received word that his train was threatened.

Attributed knowledge from a history and an interested report; no message log inspected.

logistics

supportedunresolved Britton says most of Shelby's troops had nearly used up their ammunition and halted to await a supply, one of Collins's rifled guns burst, and Blair's brigade was delayed until its horses were brought back from Wyandotte. Price says his train had been sent ahead on the Fort Scott road.

outcome

disputedpost_outcome The frozen and live results read Union victory, and NPS says the Confederates could not break the Union lines and retreated. Price says Shelby and Fagan drove the enemy six or seven miles into Westport before he recalled them to protect the train; Britton says the Federal line first fell back behind Brush Creek, then the whole Confederate line retreated.

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

responsibility

supportedunresolved Britton says Curtis came on the field and ordered his whole line to advance, and that Shelby withdrew on Price's order to fall back. Price says Shelby attacked with Fagan's two Arkansas brigades and that he himself formed the unarmed men before the train. The frozen commanders are Major Generals Sterling Price and Samuel R. Curtis.

Command roles from a history and an interested report; no automatic sole credit.

strength

unknownunresolved

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 Army of the Border and Army of Missouri; the live field reads zero. Price says the enemy engaged that day exceeded 20,000 well-armed men against his fewer than 8,000 armed, that a force of 2,000 or 2,500 threatened his train, and that he formed several thousand unarmed men and not more than 200 armed men to meet it. Britton says Curtis left three or four thousand militia in the Kansas City works and sent seven or eight thousand forward under Blunt, and that Shelby was reinforced by two of Fagan's brigades.

Interested estimates and a history's figures for different scopes; no return at the battle. None is adopted as a matched opening strength. The live zero is not measured absence.

terrain

supportedunresolved Britton says Blunt's line formed in the timber along Brush Creek, Jennison's skirmishers used a field enclosed by stone and rail fences, and the half mile south of the creek was thick brush unsuited to cavalry. NPS says Curtis had established strong defensive lines.
