Battle of Little Blue River

The Battle of Little Blue River was fought on October 21, 1864, as part of Price's Raid during the American Civil War. Major General Sterling Price of the Confederate States Army led an army into Missouri in September 1864 with hopes of challenging Union control of the state. During the early stages of the campaign, Price abandoned his plan to capture St. Louis and later his secondary target of Jefferson City. The Confederates then began moving westwards, brushing aside Major General James G. Blunt's Union force in the Second Battle of Lexington on October 19. Two days later, Blunt left part of his command under the authority of Colonel Thomas Moonlight to hold the crossing of the Little Blue River, while the rest of his force fell back to Independence. On the morning of October 21, Confederate troops attacked Moonlight's line, and parts of Brigadier General John B. Clark Jr.'s brigade forced their way across the river. A series of attacks and counterattacks ensued, neither side gaining a significant advantage.

Meanwhile, Blunt had received permission from Major General Samuel R. Curtis to make a stand at the Little Blue River, and he and Curtis returned to the field with reinforcements that brought total Union strength up to about 2,800 men. More Confederate soldiers from the divisions of Brigadier Generals Joseph O. Shelby and John S. Marmaduke arrived on the field, bringing Confederate strength to about 5,500 men. One regiment of Confederate cavalry threatened the Union flank, and Brigadier General M. Jeff Thompson's Confederate brigade pressed the Union center. The Union line fell back and the fighting largely ending around 16:00, when the Union troops reached Independence. The Union soldiers later fell back to the Big Blue River, abandoning Independence.

The next day Union soldiers commanded by Major General Alfred Pleasonton forced their way across the Little Blue River and retook Independence from the Confederates during the Second Battle of Independence. On October 23, the Confederates were defeated by Curtis and Pleasonton at the Battle of Westport, forcing Price's men to retreat from Missouri.

A study published by the American Battlefield Protection Program in 2011 determined that the Little Blue River battlefield was in fragmented condition and was threatened by highway development. It found that part of the site was potentially eligible to be listed on the National Register of Historic Places.

Background
At the start of the American Civil War in 1861, the state of Missouri was a slave state, but did not secede. However, the state was politically divided: Governor Claiborne Fox Jackson and the Missouri State Guard (MSG) supported secession and the Confederate States of America, while Brigadier General Nathaniel Lyon led Union Army forces in Missouri that remained loyal to the United States and opposed secession. Under Major General Sterling Price, the MSG defeated Union armies at the battles of Wilson's Creek and Lexington in 1861, but by the end of the year, the secessionist forces were restricted to the southwestern portion of the state by Union reinforcements. Meanwhile, Jackson and a portion of the state legislature voted to secede and join the Confederate States of America, while another element of the legislature voted to reject secession, essentially giving the state two governments. In March 1862, a Confederate defeat at the Battle of Pea Ridge in Arkansas gave the Union control of Missouri, and Confederate activity in the state was largely restricted to guerrilla warfare and raids throughout 1862 and 1863.

By the beginning of September 1864, events in the eastern United States, especially the Confederate defeat in the Atlanta campaign, gave incumbent president Abraham Lincoln, who supported continuing the war, an edge in the 1864 United States presidential election over George B. McClellan, who favored ending the war. At this point, the Confederacy had very little chance of winning the war. Meanwhile, in the Trans-Mississippi Theater, the Confederates had defeated Union attackers during the Red River campaign in Louisiana, which took place from March through May. As events east of the Mississippi River turned against the Confederates, General Edmund Kirby Smith, Confederate commander of the Trans-Mississippi Department, was ordered to transfer the infantry under his command to the fighting in the Eastern and Western Theaters. This proved to be impossible, as the Union Navy controlled the Mississippi River, preventing a large-scale crossing. Despite having limited resources for an offensive, Smith decided that an attack designed to divert Union troops from the principal theaters of combat would have an effect equivalent to the proposed transfer of troops, by decreasing the Confederates' numerical disparity east of the Mississippi. Price and the new Confederate Governor of Missouri, Thomas Caute Reynolds, suggested that an invasion of Missouri would be an effective offensive; Smith approved the plan and appointed Price to command the offensive. Price expected that the offensive would create a popular uprising against Union control of Missouri, divert Union troops away from principal theaters of combat (many of the Union troops previously defending Missouri had been transferred out of the state, leaving the Missouri State Militia as the state's primary defensive force), and aid McClellan's chance of defeating Lincoln in the election.

On September 19, Price's column, named the Army of Missouri, entered the state. The army was divided into three divisions, commanded by Major General James F. Fagan and Brigadier Generals John S. Marmaduke and Joseph O. Shelby. Marmaduke's division contained two brigades, commanded by Brigadier General John B. Clark Jr. and Colonel Thomas R. Freeman; Shelby's division had three brigades under Colonels David Shanks (replaced by Brigadier General M. Jeff Thompson after Shanks was killed in action), Sidney D. Jackman, and Charles H. Tyler; and Fagan's division contained four brigades commanded by Brigadier General William L. Cabell and Colonels William F. Slemons, Archibald S. Dobbins, and Thomas H. McCray.

Prelude
When the campaign began, Price's force was composed of about 13,000 cavalrymen, but several thousand of these men were poorly armed, and all 14 of the army's cannons were of light caliber for artillery of the war. Countering Price was the Union Department of Missouri, under the command of Major General William S. Rosecrans, who had fewer than 10,000 men on hand. These soldiers, many of whom were militiamen, were dispersed throughout the state. The Department of Missouri was composed of a series of districts and subdistricts charged with guarding specific local areas. While some of the militia organizations were well-trained, others were poorly armed and trained. While some had fought against guerrillas, experience in more traditional warfare was lacking. In late September, the Confederates encountered a small Union force holding Fort Davidson near the town of Pilot Knob. Attacks against the post in the Battle of Pilot Knob on September 27 failed, but the Union garrison abandoned the fort that night. Price had suffered hundreds of casualties in the battle, and decided to change his objective from St. Louis to Jefferson City. Price's army was accompanied by a sizable wagon train, which significantly slowed its movement. The slow progress of the Confederates enabled Union forces to reinforce Jefferson City, whose garrison was increased from 1,000 men to 7,000 between October 1 and October 6. In turn, Price determined that Jefferson City was too strong to attack, and began moving westwards along the course of the Missouri River. The Confederates gathered recruits and supplies during the movement; a side raid against the town of Glasgow on October 15 was successful, as was another raid against Sedalia.

Meanwhile, Union troops commanded by Major General Samuel R. Curtis were withdrawn from their role in suppressing the Cheyenne; the Kansas State Militia was mobilized. Major General James G. Blunt was also transferred from the Cheyenne conflict and began gathering a combination of Union Army troops and state militiamen at Paola, Kansas, near the Missouri-Kansas state border. George W. Dietzler, a major general in the Kansas State Militia, was appointed as its general-in-chief, although the troops were under Curtis's authority. The Kansas State Militia used a brigade organization, but little detail about the exact breakdown is provided in the Official Records of the War of the Rebellion. While some of the militia were technically commanded by Blunt, the militia officers serving under Blunt still considered themselves to be part of the militia organization and attempted to adhere to their former command structure. The total strength of the mobilized militia amounted to about 15,000 men.

Dietzler's militia and Blunt's division were grouped under Curtis's command as a new formation known as the Army of the Border. This army was split into two wings: one commanded by Dietzler and composed of the militia retained under his command, and other being Blunt's force. On October 14, or 15, Blunt moved his command to Hickman Mills, Missouri, where he formed it into a three-brigade division; one of the brigades was composed of Kansas militia and was led by Colonel Charles W. Blair. The two brigades composed of the Union Army troops were commanded by Colonels Charles R. "Doc" Jennison and Thomas Moonlight. Blair's command was hampered by his militia units still viewing militia officer William Fishback as their proper commander. Jennison's brigade contained one cavalry regiment and part of another, Moonlight's was composed of one cavalry regiment and parts of two others, and Blair's contained one Union cavalry regiment and three militia units. Each brigade was assigned an artillery battery; Blair's brigade was given an extra artillery section as well. This allotment resulted in Jennison's brigade having five cannons, Moonlight's four, and Blair's eight.

Price halted at Marshall on October 15, east of Blunt's column. The next day, Curtis moved most of the Kansas militiamen not assigned to Blunt to Kansas City, Missouri, but was prohibited by Thomas Carney, the governor of Kansas, from taking them east of the Big Blue River. Curtis had previously promised Carney that the militia would only travel as far as was necessary to protect Kansas. On the 17th, Blunt detached his militia brigade to Kansas City, and then sent his other two brigades to Holden.

On October 18, Blunt's advance guard, commanded by Moonlight, occupied the town of Lexington, hoping to cooperate with a force commanded by Brigadier General John B. Sanborn to catch and trap Price. However, Sanborn's force was too far south of Lexington to move in concert with Blunt. Additionally, Blunt learned that Price was only 20 miles away at Waverly; he also received word from Curtis that the political authorities in Kansas would not allow the latter to send more militiamen to Blunt. Blunt then made the decision to reinforce his outer positions and resist the anticipated Confederate advance. Shelby's division attacked the Union line at Lexington on October 19, beginning the Second Battle of Lexington, but Blunt's troops held. The Union troops retreated once Price deployed men of Fagan's and Marmaduke's divisions into the fray.

Moonlight's stand
After the battle at Lexington, Blunt's forces fell back to the west, Moonlight's brigade serving as the rear guard. Early on the morning of October 20, Blunt decided to halt and defend a position east of the Little Blue River. Blunt requested reinforcements from Curtis, but the restrictions on the movement of the Kansas Militia prevented Blunt from being reinforced at the Little Blue River. Curtis therefore ordered Blunt to leave a holding force at the Little Blue River and fall back to the Big Blue River. Blunt argued for a stand at the river but complied with his orders, falling back to Independence that evening. The 11th Kansas Cavalry Regiment, supported by four cannons, was left behind to serve as a rear guard under Moonlight's command. The strength of this force amounted to either 400 or 600 men. Two companies of the 11th Kansas Cavalry and the cannons were placed at a bridge over the river with instructions to burn it when the Confederates arrived, while single companies guarded fords, one within either 1 mile or 2 miles north of the bridge and the other 4 miles to the south of the bridge. The remainder of the 11th Kansas Cavalry was held as a reserve. Despite these precautions, other fords closer to the bridge were left unguarded, and the river was shallow enough to be crossed at many points. The defenders simply were not familiar with the terrain, while some of the Missouri Confederates were. Union prisoners informed Price that a stand would be made at the Little Blue.

The Confederates struck at about 07:00 on the morning of October 21, the advance being led by Company D of the 5th Missouri Cavalry Regiment. The Confederate company lost over a third of its strength in a sharp fight with Union skirmishers, who were eventually driven across the bridge. After Confederate pressure grew strong enough that the defenders at the bridge determined that they would not be able to hold out, they set fire to the bridge. Meanwhile, Clark's Confederate brigade arrived, and Marmaduke sent the 4th Missouri Cavalry Regiment to find a ford south of the bridge, while the 10th Missouri Cavalry Regiment found a crossing about halfway between the bridge and the Union company stationed north of it. The northward Union company was outflanked and retreated, later rejoining other parts of their regiment. Clark, in turn, ordered more of his brigade to cross behind the 10th Missouri Cavalry. The ford soon became congested, slowing Confederate movements.

The Union troops holding the burning bridge also retreated, although the Confederates were able to put out the flames, rendering it still usable. The 11th Kansas Cavalry, with the exception of the isolated company to the south, retreated to a hilltop line marked by a stone wall. Moonlight's four cannons were deployed here as well. The 10th Missouri Cavalry pursued them uphill and attacked, but was repulsed in disarray by the Kansans and the fire from their repeating rifles. Confederate Colonel Colton Greene was able to get his 3rd Missouri Cavalry Regiment across the ford, although the men of the 10th Missouri Cavalry had already routed. Three cannons from Harris's Missouri Battery also crossed, and moved into a position to support Greene. The whole of the 11th Kansas Cavalry Regiment counterattacked, while the 3rd Missouri Cavalry Regiment was only about 150 men strong. Once the combat reached close quarters, the Confederate artillery was no longer effective, as the risk of accidental friendly fire was too great. Instead, the cannoneers fired blanks in an attempt to mislead the Union troops into thinking they were under heavy artillery fire. The Kansans retreated, and Greene believed that the blank cartridge ruse had been effective. The two sides engaged in a series of counterattacks, neither gaining a significant advantage.

Blunt arrives
Meanwhile, Blunt had been able to get permission from Curtis to fight at the Little Blue River. Blunt then began a return from Independence to the river, bringing his non-militia units and 900 men and six cannons under the command of Colonel James H. Ford. Ford's command consisted of McLain's Colorado Battery, part of the 16th Kansas Cavalry Regiment, and the 2nd Colorado Cavalry Regiment, which were transferred from Curtis's command to Blunt's, becoming a fourth brigade for the latter. The 2nd Colorado Cavalry has previously been sent by Rosecrans to Curtis and McLain's battery had been stationed at Paola until October. Two regiments from Jennison's brigade also accompanied Blunt. Back at the Little Blue River, Clark's brigade had finally gotten across the river. Around 11:00, Moonlight observed some of Shelby's men approaching in support of Clark's brigade. Despite being farther from the battlefield than Fagan's division, Shelby's division was committed to the fighting, as it was considered more reliable. Blunt's command also arrived on the field at about 11:00. By then, Moonlight's force had fallen back to about 2 miles from the river. Between the commands of Moonlight and Blunt, there were about 2,600 Union men on the field, with the support of 15 cannons. The two regiments from Jennison's brigade supported the Union right, while Ford's men moved to the left. Elements of both Marmaduke's and Shelby's divisions totaling about 5,500 men were present. While numerically inferior, the Union troops had superior firepower. The Union line was held on the left by the 15th Kansas Cavalry Regiment, which was supported by five cannons. The Union line stretched to the north, with the 3rd Wisconsin Cavalry Regiment next to the 15th Kansas Cavalry, followed by the 2nd Colorado Cavalry Regiment, McLain's battery, the 16th Kansas Cavalry Regiment, and the 11th Kansas Cavalry. Four cannons supported the 11th Kansas Cavalry. About one quarter of the Union soldiers were sent to the rear to hold the men's horses. The men from both sides were deployed dismounted.

The increased Union numbers began to put substantial pressure on Greene's regiment. Wood's Missouri Cavalry Battalion arrived to reinforce Greene, and aligned in an orchard. After some fighting and a Union counterattack, the Confederates began to run low on ammunition and started a retreat, which was accompanied by Harris's Battery. Just as the Confederate line was beginning to collapse, the 7th Missouri Cavalry Regiment and Davies's Missouri Cavalry Battalion of Clark's brigade arrived to shore up the line. Additionally, Thompson's brigade of Shelby's division crossed over and deployed to the left of Clark's brigade. After Thompson's men made it across the river, Shelby also fed Jackman's brigade into the fight. Shelby then ordered an assault against the Union line. Most of Jackman's brigade was inexperienced and made little progress, but Nichols's Missouri Cavalry Regiment, which was still mounted, advanced against the Union left flank. Curtis arrived on the battlefield at 13:00, accompanied by two more cannons. There were now about 2,800 Union troops on the field. Curtis noticed Nichols's unit's incursion towards the Union flank, and sent McLain's Battery and two other cannons to counter the threat; as these cannons were taken from other parts of the Union lines, it weakened the Union center.

Shelby took advantage of the weakened Union center by pressing the attack harder. Thompson's men began pushing forward. Complicating matters for the Union soldiers was Curtis's decision to send the wagons containing more ammunition back to Independence. With ammunition running low, Nichols's men threatening one flank, and Thompson pressing the Union center, the Union troops began conducting a fighting withdrawal. Blunt placed Ford in charge of the rear guard, although in practice, Moonlight shared command responsibility with Ford, whose men conducted a rear guard maneuver in which the men deployed in two ranks. The front rank resisted the Confederate pursuit until falling back behind the second rank, after which the process was repeated. During the retreat, McLain's Battery was caught in an exposed position, but was rescued by a counterattack made by elements of the 11th Kansas Cavalry. Later, these elements of the 11th Kansas Cavalry were also stuck in an exposed position and had to be rescued by a charge from the 2nd Colorado Cavalry. The 11th and 16th Kansas Cavalry and McLain's battery made a stand on a ridge 2 miles east of Independence, the 16th even making a brief counterattack, but this position had become indefensible by around 15:00 and was abandoned. The Confederates had become disorganized and Blunt used a lull in the fighting to begin to form a line at Independence. By 16:00 large-scale fighting had ended. The retreat to Independence had been over 7 miles. Later that afternoon, Blunt ordered a retreat to the Big Blue River, which was lightly pursued by the Confederates. Some skirmishing occurred within Independence itself during the retreat. A detail of Union soldiers destroyed some army supplies in the town, while civilians within the town took potshots at the retreating Union troopers. It is not known if the civilian gunmen were pro-Confederates, or were under the mistaken belief that the Union soldiers were guerrillas in captured uniforms, or if they were attempting to hamper the destruction of military supplies, hoping to take them themselves. By nightfall, Curtis's men were on the west side of the Big Blue River, and Price's army was in the Independence area.

Aftermath and preservation
Official casualty numbers are only known for a few units on each side. The 11th and 15th Kansas Cavalries and the 2nd Colorado Cavalry combined had 20 men killed. On the Confederate side, the 3rd Missouri Cavalry Regiment suffered 31 killed and wounded, while a total of three men were killed between Davies's battalion and the 10th Missouri Cavalry Regiment. Among the Union dead was Major Nelson Smith of the 2nd Colorado Cavalry, while Confederate guerrilla leader George Todd was also killed. Todd had led a group of guerrillas during the battle; he was shot in the throat during the final stages of the action. Confederate surgeon William McPheeters reported that 10 wounded Union soldiers were left in Independence, and that civilians reported about 100 more had been taken with the Union troops during the retreat. McPheeters also noted seeing the bodies of dead Union soldiers strewn along the road from the river to Independence. Historian Mark Lause estimates that the Union may have lost up to about 300 men, and the Confederates more. Shelby later described the fight as the beginning of significant difficulties for his division during the campaign.

The day after the battle, Price sent Shelby south of Curtis's main line along the Big Blue River. In the initial stages of the Battle of Byram's Ford, Shelby's men forced their way across the Big Blue River, causing Curtis to order a withdrawal to Brush Creek. Meanwhile, Union cavalry commanded by Major General Alfred Pleasonton attacked Price's rear guard from the east in the Second Battle of Independence. After pushing across the Little Blue River, Pleasonton's men struck Cabell's Confederate brigade, capturing both men and two cannons, as well as taking the town of Independence. On October 23, Price's men fought the Battle of Westport, where they were defeated by Curtis's and Pleasonton's commands. The Confederates began retreating through Kansas, before reentering Missouri on October 25. Price's survivors eventually reached Texas via Arkansas and the Indian Territory, suffering several defeats along the way. Price lost over two thirds of his men during the campaign.

A study published by the American Battlefield Protection Program (ABPP) in 2011 determined that the Little Blue River battlefield was fragmented, but that there was still potential for future preservation. The study also noted that the site was threatened by highway construction. The battlefield is not listed on the National Register of Historic Places, but the ABPP found that 2493.72 acres are potentially eligible for listing. At the site, 6.50 acres are currently under some form of permanent protection. There is public interpretation at the site but no visitor's center. A driving tour, with interpretative markers, has been established for the battlefields of Little Blue and Second Independence together. The site is part of Freedom's Frontier National Heritage Area and the Civil War Roundtable of Western Missouri acts as a battlefield friends group.
