Hartville MO019

1863-01-09 to 1863-01-11 · MO · Marmaduke's First Expedition into Missouri [January 1863] · frozen result: Confederate · NPS summary (as listed)

CWSAC description
John S. Marmaduke led a Confederate raid into Missouri in early January 1863. This movement was two-pronged. Col. Joseph C. Porter led one column, comprising his Missouri Cavalry Brigade, out of Pocahontas, Arkansas, to assault Union posts around Hartville, Missouri. When he neared Hartville, on January 9, he sent a detachment forward to reconnoiter. It succeeded in capturing the small garrison and occupying the town. The same day, Porter moved on toward Marshfield. On the 10th, some of Porter's men raided other Union installations in the area before catching up with Marmaduke's column east of Marshfield. Marmaduke had received reports of Union troops approaching to surround him and prepared for a confrontation. Col. Samuel Merrill, commander of the approaching Union column, arrived in Hartville, discovered that the garrison had already surrendered and set out after the Confederates. A few minutes later, fighting began. Marmaduke feared being cut off from his retreat route back to Arkansas so he pushed Merrill's force back to Hartville, where it established a defense line. Here, a four-hour battle ensued in which the Confederates suffered many casualties but compelled the Yankees to retreat. Although they won the battle, the Confederates were forced to abandon the raid and return to friendly territory.

Command responsibility (ledger v2)

US: Samuel Merrill

Grade B under rule 2; echelon detachment_or_post.

Single CWSAC listing. The frozen interval begins January 9, and the description and Britton both open with Porter's detachment surrounding Hartville on the 9th and capturing its small garrison ('a detachment of thirty-five Union militia'), whose commander no inspected passage names. Merrill's column, which Britton says Warren put under Merrill ('he ordered Colonel Merrill, the officer next in rank, to take command'), and which NPS calls the approaching Union column under Merrill, reached Hartville on the morning of the 10th, after the garrison's capture on the 9th (Britton: 'where they arrived the next morning at sunrise'), and fought there on the 11th. So no passage states Merrill's command of the side's engaged forces at first combat, and none names another officer (rule 2, grade B, as for NC010 US in v1). Marmaduke calls him 'General Merrill'; Britton and the listing give Colonel; identity is not in doubt. Echelon from the frozen forces row ('Detachment of infantry, cavalry, and artillery').

Confederate: John S. Marmaduke

Grade A under rule 2; echelon division.

Porter's column, which captured the Hartville garrison on the 9th, was one of the two columns of Marmaduke's expedition: Marmaduke says he had ordered Porter to take command of White's brigade and march to a junction at Hartville. Britton puts the combined forces 'under General Marmaduke' on the 11th, and Marmaduke's report says he met and fought Merrill at Hartville. Porter led a column (subordinate context), so rule 2 keeps Marmaduke, grade A.

information

supportedunresolved Britton says Merrill learned from citizens of Porter's capture of the garrison and from prisoners that Marmaduke's combined force was in front, and that Marmaduke had word of a strong Federal cavalry force pursuing him. Marmaduke says that, hearing of a strong cavalry force in his rear, he chose not to fight between two forces.

logistics

supportedunresolved Britton says Merrill's infantry rode in four-mule government wagons, that the stampede of Porter's caisson horses left his battery without ammunition, and that Dunlap left Hartville for want of provisions. Marmaduke says the retreat crossed a country laid waste, with neither food for men nor horses, and that his horses were mostly unshod and very poor.

A history and an interested report; no supply return inspected.

objectives

supportedunresolved Britton says Merrill's column was ordered to reinforce Springfield, that Marmaduke marched around it to keep an open line of retreat south, and that Merrill, knowing his weakness, sought to make the Confederates attack him. Marmaduke says he turned the force in front after securing a safe line of retreat.

Stated aims from a history and an interested report.

ordered Brigadier-General Fitz Henry Warren, command- ing at Houston, in Texas County, to reinforce the Federal garrison at Springfield by forced marches.

outcome

disputedpost_outcome The frozen result reads Confederate victory and the live result Confederate Victory. Marmaduke says the enemy gave way and retreated in disorder, leaving dead, wounded and arms. Britton says most of Merrill's command retired on the Lebanon road, but Dunlap's regiment held its position until the Confederates retreated before sunset, leaving their dead and severely wounded. NPS says the Confederates compelled the Union to retreat but abandoned the raid.

Retain the original result and engagement interval; later movements and campaign contribution are different measures. No new probabilities or individual causal credit. The accounts conflict on which side left the field.

disputedpost_outcome The frozen casualty text reads 407 total (US 78; CS 329), as does the live field. Britton gives the Federal loss as 7 killed, 64 wounded, 5 prisoners and 2 missing, and Marmaduke's reported loss as 12 killed, 96 wounded and 3 missing. Marmaduke's January 18 dispatch gives 15 killed and 70 wounded, including MacDonald, Wimer and Kirtley. The Hartville garrison taken on January 9 is given by Britton as thirty-five militia and by Marmaduke as some 50. The expedition total and the No. 9 return are recorded under Springfield and not assigned here.

responsibility

supportedunresolved Britton says Warren could not accompany the column and put Colonel Merrill in command, that Shelby's and then Porter's brigades attacked, Porter being wounded, and that Dunlap's regiment held the field after the rest of Merrill's command had retired. Marmaduke calls his opponent General Merrill. NPS names Merrill as commander of the Union column. The frozen commanders are Brigadier General John S. Marmaduke and Colonel Samuel Merrill; the live page lists Marmaduke without a rank.

Command roles from a history, an interested report and a summary; the listed commanders do not receive automatic sole credit. Marmaduke's 'General Merrill' differs from Britton's 'Colonel Merrill' and the frozen rank of Colonel.

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 field reads Detachment of infantry, cavalry, and artillery (approx. 700) [US], and the frozen US bound is 700; the live field reads 700 (US 700; CS 0). Britton says Merrill's column numbered about eight hundred, joined at Hartville by one hundred and eighty cavalry, that prisoners put the Confederates at five thousand, that eight hundred Federal muskets fired the first volley, and that Dunlap was left with his regiment of two hundred and fifty men. Marmaduke's January 18 dispatch gives the enemy as 1,500 infantry and 500 cavalry and Porter's column as 600; his February 1 report gives 2,500 Federal troops and Porter about 700 effective men.

March strengths, a prisoners' estimate and interested enemy estimates at different times. The frozen 700 has no inspected basis. None is adopted as a matched opening strength. The live CS zero is not measured absence.
