From Fort Hindman, at Arkansas Post, Confederates had been disrupting Union shipping on the Mississippi River. Maj. Gen. John McClernand, therefore, undertook a combined force movement on Arkansas Post to capture it. Union boats began landing troops near Arkansas Post in the evening of January 9, 1863. The troops started up river towards Fort Hindman. Maj. Gen. William T. Sherman’s corps overran Rebel trenches, and the enemy retreated to the protection of the fort and adjacent rifle-pits. Rear Adm. David Porter, on the 10th, moved his fleet towards Fort Hindman and bombarded it withdrawing at dusk.

On September 10, 1863, Maj. Gen. Fred Steele, Army of Arkansas commander, sent Brig. Gen. John W. Davidson’s cavalry division across the Arkansas River to move on Little Rock, while he took other troops to attack Confederates entrenched on the north side. In his thrust toward Little Rock, Davidson ran into Confederate troops at Bayou Fourche.

In late November, Maj. Gen. Thomas C. Hindman detached Brig. Gen. John Marmaduke’s cavalry from Van Buren north to occupy the Cane Hill area. Hearing of this movement, Brig. Gen. James Blunt advanced to meet Marmaduke’s command and destroy it, if possible. The Union vanguard encountered Col. Joe Shelby’s brigade, which fought a delaying action to protect their supply trains. Shelby gradually gave ground until establishing a strong defensive perimeter on Cove Creek where he repulsed a determined attack.

Union Brig. Gen. William Vandever pursued Brig. Gen. John S. Marmaduke to Chalk Bluff, where the Confederates hoped to cross the St. Francis River. To ford the river, Marmaduke established a rearguard that received heavy punishment on May 1-2.

Union Maj. Gen. James G. Blunt ordered Col. William Cloud to continue in pursuit of the Confederate forces that had withdrawn from Fort Smith and were chased to Old Jenny Lind. The Rebels turned on Cloud and skirmished with him at the base of Devil’s Backbone. Cabell’s forces ambushed approaching Union troops and momentarily halted their advance.

During the expedition, Union forces sought a ford to cross the Little Missouri River because other roads were impassible. They reached Elkin’s Ferry before the Confederates. As they crossed, the Confederates attempted to stop them but to no avail.

Lt. Gen. Theophilus Holmes’s troops attacked Helena in an attempt to relieve pressure on Vicksburg. Although the Rebels had more troops and did initially capture some of the fortifications, the Union forces repelled them.

Union Maj. Gen. Samuel R. Curtis moved on Helena, Arkansas, in search of supplies to replace those that had been promised but never delivered by the Navy. The Confederates under Maj. Gen. Thomas C. Hindman attempted to prevent this change of supply base by continually skirmishing with the Union troops. The Confederates made a stand at the Cache River on July 7. As Union Col. C.L. Harris moved forward with elements of the 11th Wisconsin, 33rd Illinois, and the 1st Indiana Cavalry, moved forward, he blundered into an ambuscade.

Maj. Gen. Fred Steele’s forces retreated from Camden after being mauled at Marks’ Mills and Poison Spring. On the afternoon of April 29, the Union forces reached Jenkins’ Ferry and began crossing the Saline River, which was swollen by heavy rain. Rebel forces arrived on the 30th and attacked repeatedly.

A Union force escorted 240 wagons from Camden to Pine Bluff to pick up supplies and transport them back to Maj. Gen. Fred Steele’s army. At first the Union escort rebuffed Rebel attempts to halt them. Then the Confederates moved in on the Union rear and front, causing a rout.

Mower camped near Sunnyside Landing on the evening of June 5 and took up his line of march again the next morning. The skirmishing Confederates fell back to Red Leaf where Col. Colton Greene and his men were encamped. As the Federals advanced, Greene’s men, assisted by artillery, fought a delaying action at Ditch Bayou and then withdrew to Parker's landing on Bayou Mason.

On the night of March 6, Maj. Gen. Earl Van Dorn set out to outflank the Union position near Pea Ridge, dividing his army into two columns. Learning of Van Dorn’s approach, the Federals marched north to meet his advance on March 7. This movement—compounded by the killing of two generals, Brig. Gen. Ben McCulloch and Brig. Gen. James McQueen McIntosh, and the capture of their ranking colonel—halted the Rebel attack. Van Dorn led a second column to meet the Federals in the Elkhorn Tavern and Tanyard area. By nightfall, the Confederates controlled Elkhorn Tavern and Telegraph Road.

At 8:00 am, October 25, Col. Powell Clayton sent a company of cavalry toward Princeton which ran into Brig. Gen. John S. Marmaduke’s men advancing. After some fire, the Rebels, under a flag of truce, came forward demanding surrender. Lt. M.F. Clark answered that there would be no surrender. Clayton slowly retreated back into Pine Bluff. In the meantime, about 300 African-American soldiers rolled cotton bales out of the warehouses for barricades to protect court square.

Dwindling supplies for his army at Camden forced Maj. Gen. Fred Steele to send out a foraging party to gather corn that the Confederates had stored about twenty miles up the Prairie D’Ane-Camden Road on White Oak Creek. The party loaded the corn into wagons, and on April 18, Col. James M. Williams started his return to Camden. Brig. Gen. John S. Marmaduke’s and Brig. Gen. Samuel B. Maxey’s Confederate forces arrived at Lee Plantation, about fifteen miles from Camden, where they engaged Williams.

On April 10, Maj. Gen. Fred Steele’s Union forces, combined with Brig. Gen. John M. Thayer’s division, marched south from the Cornelius Farm. They soon encountered a Confederate line of battle at Prairie D’Ane and attacked, driving it back about a mile before being checked. Skirmishing continued throughout the afternoon of April 11, forcing Steele to divert line of march forces away from Shreveport toward Camden.

Maj. Gen. Thomas C. Hindman sought to destroy Brig. Gen. Francis Herron’s and Brig. Gen. James Blunt’s divisions before they joined forces. Hindman placed his large force between the two Union divisions, turning on Herron first and routing his cavalry. As Hindman pursued the cavalry, he met Herron’s infantry which pushed him back. The Rebels then established their line of battle on a wooded high ridge northeast of Prairie Grove Church. Herron brought his artillery across the Illinois River and initiated an artillery duel.

On the morning of June 17, USS Mound City, St. Louis, Lexington, Conestoga, and transports proceeded up White River towards Saint Charles attempting to resupply Maj. Gen. Samuel R. Curtis’s army near Jacksonport. A few miles below Saint Charles, the 46th Indiana Infantry under the command of Col. Graham N. Fitch disembarked, formed a skirmish line, and proceeded upriver towards the Rebel batteries on Saint Charles bluffs, under the command of Capt. Joseph Fry, C.S.N.
