Confederate General Sterling Price's 1864 Missouri Raid
Item 3 of 14
Though not fought on the same ground as the previous three Civil War battles near Boonville, this 1864 skirmish underlines the town's importance as a crucial crossroads in central Missouri during the conflict. The battle itself, albeit small by Civil War standards, was an important step in the six weeks of Confederate General Price's Missouri Expedition, during which he led an army of 12,000 in a failed bid to claim the border state for the Confederacy once and for all. Had he succeeded, it may have been a powerful political blow against the reelection of Abraham Lincoln that November, and could perhaps have led to Southern independence. The battlefield itself is not preserved, but other important moments in Price's Raid are well-marked.

  • Confederate General Sterling Price, a former governor of Missouri who commanded in the region for much of the war. After the Confederate surrender, he fled to Mexico and lived briefly in a colony for ex-Confederates in Veracruz.
  • Confederate Major General James Fagan, commanding one of three of Price's divisions during the raid. He conducted the Rebel rearguard at Boonsville. Despite his chosen side during the war, afterward he was appointed a US Marshal by President Grant.
  • Confederate Colonel Sidney Jackman, who commanded a force of Confederate cavalry during the 4th Battle of Boonville. He would figure prominently in the coming campaign; his brigade was often entrusted with crucial positions and tasks.
  • Union General John B. Sanborn just before the war. He commanded Union forces at Boonville and would distinguish himself again later in the campaign at the Battle of Westport, where Price's army was vanquished.
  • Albert Castel's book is an invaluable resource on the war in Missouri and Kansas.

By the end of the summer in 1864, the tide of the American Civil War had turned against the southern Confederacy. Union general William T. Sherman was devastating the southern heartland on his "March to the Sea," and Robert E. Lee's Confederate army was under siege in Petersburg, Virginia. Noticing that the border state of Missouri, which harbored many Confederate sympathizers but had never officially seceded, was lightly defended at the time, Confederate General Kirby Smith conceived a plan for a fast but powerful raid into Missouri, seizing St. Louis and Jefferson City with the goal of installing a Confederate governor. This coup would hopefully contribute to the defeat of Abraham Lincoln in the upcoming U.S. Presidential elections and open the way for an armistice and Southern independence.

Confederate General Sterling Price was sent with 12,000 troops into Missouri on September 19, 1864. While stronger numerically than the scattered Union garrisons in the state, nearly a quarter of his force were deserters who had been apprehended and reconscripted. Thousands lacked weapons, tents, shoes, or other essentials. Price experienced initial successes against the surprised Yankees, but the Union commander of the Department of Missouri, William S. Rosecrans, began to organize a response. Had Price progressed rapidly to St. Louis he may have taken it with little struggle, but he decided to assault a 1,200-man garrison at Fort Davidson in Pilot Knob, Missouri on Sept. 27. Despite enjoying vast numerical superiority, Price's badly organized attack suffered monstrous casualties--nearly a tenth of his overall strength--and failed to take the fort. Adding insult to injury, the Union garrison slipped out overnight, blew up the fort, and led Price's pursuit on a merry chase before successfully elduing his grasp. Thus far, the Confederate invasion had little to show for itself.

By this time, Rosecrans had reinforced St. Louis and Price knew it was impractical to assault the city. The Confederates swung northwest toward Jefferson City, still hoping to take the capital and install their gubernatorial aspirant, Thomas C. Reynolds. But Price advanced too slowly once again, arriving outside Jefferson City on Oct. 7--one day after the Union garrison had received reinforcements to the tune of 2,500 men and a new commander, General Alfred Pleasonton. Though Price still outnumbered the Federals, Missouri's capital was heavily fortified and would have proved too costly to assault. Price formed up to attack but withdrew after a brief artillery duel and moved his army northwest to Boonville, succeeding only in surprising and capturing the 300-man Union garrison there.

Less than three weeks into his raid, Price had failed to achieve his primary objectives. Missouri's two major cities remained in Federal hands, and Confederate governor-in-exile Reynolds had no state over which to preside. So Price moved to complete a secondary set of objectives: reinforce his columnn with militia troops drawn from pro-Confederate counties, then cut a destructive swath through eastern Kansas, which was firmly in Union hands.

Boonville was instrumental to the former since it lay in the heart of "Little Dixie," a region of central Missouri with a high percentage of slaveholding estates and largely Confederate sympathies. An important junction on the route from Kansas City to Jefferson City and St. Louis, Boonville had already seen three battles prior to 1864--all of which were reverses for the Confederates. While the military action at the 4th Battle of Boonville proved the exception, it did little to reverse the demoralizing downward spiral of Price's Raid.

The Confederate commander spent two days in the town organizing over a thousand (mostly unarmed) militia recruits who flooded in from the surrounding countryside. But Price's men soon alienated the sympathetic populace with unruly behavior and looting, which had been a problem since the earliest days of the raid. Governor-in-exile Reynolds later wrote:

"It would take a volume to describe the acts of outrage; neither station, age, nor sex was any protection. Southern men and women were as little spared as Unionists..."2

One of Price's ablest commanders, Brigadier Gen. M. Jeff Thompson, wrote of having his hands full disciplining his own troops, and lamented that,

"The plunder of Boonville nearly completed this demoralization [of Price's army] for many officers and men loaded themselves, their horses and wagons with 'their rights' and now wanted to turn Southward and save what they had...the hotel occupied as General Price's own headquarters was the scene of public drunken revelry by night."2

When Price withdrew from Boonville on Oct. 11, he took with him the last able-bodied Confederate men of the region and much of its goodwill, having plundered through many of its towns and farmsteads.

The battle itself was less dramatic. After Price retreated from Jefferson City's formidable defenses, General Pleasonton had sent on his trail some 2,500 cavalrymen under General John Sanborn. Pleasonton lacked the numbers to engage Price in pitched battle but instructed Sanborn to maintain contact with the enemy. The threat to Price's rear would keep Pleasonton apprised of the enemy's whereabouts, and encourage Price to deviate westward toward Kansas. There Rosecrans and Pleasonton hoped to trap him between their forces and those of General Samuel Curtis of the Department of Kansas.

To that end, Sanborn aggressively tracked Price's progress, until Price's rearguard under Major General James Fagan was forced to engage. A short, inconclusive skirmish followed, bleeding over into more action between Rebel and Yankee cavalry on the morning of the 12th. Only one Union casualty was reported, and fewer than 25 Confederates were hurt of some 600 engaged5. Sanborn’s men were forced back, but the trap was closing around Price, as General Pleasonton's prediction of Oct. 11 began to take shape:

"[Price] will have to go south through Kansas, as he cannot subsist his force through the western tier of counties of this State; they are so destitute, so I am reliably informed."1

After several more battles and three more weeks of marching, Price would be defeated decisively in Kansas at Westport and Mine Creek, shattering Confederate military power in the region for the duration of the war.
