Curtis’s mission was clear: remove Confederate forces from Missouri. As long as Price and the Missouri State Guard remained in Missouri as a potential threat to St. Louis, federal forces looking to move down the Mississippi River would have to be kept near that vital city. Starting in January 1862, the federal Army of the Southwest left Rolla, marching toward Springfield. Price’s Missouri State Guard was taken by surprise, and it retreated in a disorderly manner toward the southwest corner of the state.
Price knew that the further the federals were drawn away from the railroad head at Rolla, the more vulnerable they became. Also, Price was falling back toward Confederate forces under Brigadier General Ben McCulloch in northwest Arkansas. Reuniting the two forces would give the Confederates a significant numerical advantage over Curtis, but getting Price and McCulloch to work together had previously proved impossible. Something had to change.
Confederate President Jefferson Davis tried to solve the command issues by placing Major General Earl Van Dorn in command of the combined force on January 29, 1862. Van Dorn was a West Point graduate, class of 1842, and Davis clearly hoped that Van Dorn’s professional background could reenergize the rebel war effort in the Arkansas-Missouri region. After Price’s headlong retreat into Arkansas, where the Boston Mountains allowed him to escape from Curtis’s forces, Van Dorn united Price and McCulloch’s forces into the Confederate Army of the West. After this reorganization of the Confederate forces under his command, Van Dorn decided to attack the federals while they were at the end of a very long and tenuous supply line.
Van Dorn’s plan to destroy the Unionists was bold: move around the federal force and strike it from the rear. This required almost superhuman efforts from the men in Confederate ranks. The 16,000-man Army of the West’s attempts to outflank the 10,500-man Army of the Southwest started the Battle of Pea Ridge on March 7, just east of modern-day Bentonville, Arkansas. The flanking attempts failed and the federals spoiled the rebel attacks in a day of ferocious fighting.
On the following day [January 30, 1862] at Pea Ridge, the Army of the Southwest counterattacked and drove the Confederates from the field in a stunning victory. The Confederates suffered approximately 2,000 casualties (killed, wounded, and missing), while the Federals took 1,300. The rebel retreat to Fort Smith and to Van Buren, Arkansas along the Arkansas River (in early March) was brutal. To make matters worse, Van Dorn took the battered remnants of the Army of the West, including the Missouri State Guard, to the east bank of the Mississippi (too late to participate in the Battle of Shiloh, Tennessee on April 6-7, where the Union won another victory). The combination of the Confederate defeat at Pea Ridge and Van Dorn’s removal of the Army of the West essentially abandoned formal control of Missouri to federal forces for the rest of the war.

1863 January 28-29, 1863 in Chantilly, Virginia - On January 28, Col. John S. Mosby and his Confederate raiders neared the town of Chantilly. Ahead of them were a party of Union vendettes, the mounted pickets of the 18th Pennsylvania Cavalry. Mosby deployed his men and, at a signal, the Confederates charged forward into the Federals. The Confederates grabbed 9 Federals, including their horses and weapons. They just as quickly disappeared back into the woods.

January 29, 1863 in Middleburg, Virginia - On January 29, word of the Confederate attack at Chantilly reached the nearby Union command. They ordered a pursuit of Col. John S. Mosby's Confederate raiders. Col. Percy Wyndham and 200 Union cavalrymen of the 5th New Jersey Cavalry rode to Middleburg. They looked around town and upon not seeing any Confederates, started to leave town. Mosby and 7 other troops and attacked the rear of the Union column. After a brief clash, both sides left the area. Union suffered 1 killed and 3 captured. The Confederates suffered 3 captured.

1864 On January 29, 1864 Brig. Gen. Thomas L. Rosser entered Moorefield with his Confederate force. He had learned of a large Union supply train that was heading to Petersburg.
On January 30, Rosser discovered that the train was at the town of Medley. The train was being guarded by several Union regiments. Rosser decided on a plan that would have one of his regiments around the rear of the Federals, the rest of his force would move to the flank, and he would have an artillery piece fire from the Union front. The plan worked out just the way he planned it.
Rosser stampeded the Union cavalry and then routed the remaining 350 Union soldiers with a dismounted attack. In the end, Rosser had captured 95 wagons from the supply train. The final casualties are unknown.

January 29, 1865 in Mooresfield, West Virginia - On January 29, Brig. Gen. Thomas L. Rosser continued his raid and entered the town of Mooresfield. While there, the Confederates stampeded a supply train and attacked the local Union garrison. The Confederates drove away the Federals and proceeded to captured 95 wagons. https://www.mycivilwar.com/battles/1865s.html
