American Civil War

The 15th (Northwest) Arkansas Infantry Regiment (1861–1865) was a Confederate Army infantry regiment during the American Civil War. The unit was originally formed as the 3rd Arkansas Infantry Battalion. After receiving the required 10 companies, the unit was redesignated as the 21st (McRae's) Arkansas Infantry Regiment. Upon recognition that there was already a 21st Arkansas, the unit was again redesignated as the 15th Arkansas Infantry Regiment. This was the third Arkansas unit to bear the designation "15th Arkansas". The others are the 15th (Josey's) Arkansas Infantry Regiment and the 15th (Gee/Johnson) Arkansas Infantry Regiment. The unit saw action both west and east of the Mississippi, before serving in the Vicksburg campaign. The regiment was surrendered at Vicksburg in July 1863. After being paroled and exchanged, the regiment was consolidated with other depleted Arkansas regiments to form the 1st (Trans-Mississippi) Arkansas Consolidated Infantry Regiment.

This unit can be traced back to four companies of Arkansas State Troops from Benton, Franklin and Yell counties, which marched to Bentonville in July 1861 to be assigned to a regiment of Arkansas State Troops. Instead, they were intercepted by Brigadier General Ben McCulloch, commanding Confederate forces in northwest Arkansas, organized into a battalion under command of Lieutenant Colonel Dandridge McRae, and mustered directly into the service of the Confederate States on July 15, 1861. Brigadier General McCulloch intended to increase the battalion to a regiment. He already had two Arkansas regiments enrolled in Confederate service, the 1st and 2nd Arkansas Mounted Rifles, and McRae's outfit was to form the basis for a 3rd Arkansas Regiment so it was named as the 3rd Battalion Arkansas Infantry.

It appears that a volunteer militia company, known as the "Johnson County Lancers", Commanded by Capt. Bastion Whitehurst Cox, raised from the 10th Regiment, Arkansas State Militia, of Johnson Country was also assigned to Lt Col McRea's battalion during the Wilson's Creek Campaign. This company apparently disbanded after Wilson's Creek and did not become a part of the 15th Arkansas (Northwest).
