I would still like to find a match for the 48th Arkansas Mounted Infantry. It is unclear who was the commander of the 48th Arkansas or which counties the regiment was recruited from. There are no surviving muster rolls for the regiment; in fact the only documentation that exists for the unit is a list of prisoners captured on October 24, 1864 at Mound City, Kansas during Price's Raid. Since General Price generally referred to his units by the name of the unit commander, the reports from Price's raid rarely contain the numerical designation of the unit. Because the names of the other 40 series regimental commanders are known, I have speculated that the 48th may have been the numerical designation of Colonel Charles H. Carlton's regiment. Like the other 40 series regiments, Carlton's regiment was raised in the summer of 1864. The only numerical designation known to be associated with the Carlton's regiment is the 28th Arkansas Cavalry. Another 40 series regiment, Colonel James H. McGhee's 44th Arkansas Infantry (Mounted) was also previously known as the 29th Arkansas Cavalry Regiment. Another possibility for the identity of the 48th is a former infantry unit which was mounted for Price's Raid, Colonel James W. Rogan's 30th Arkansas Infantry Regiment. With the exception of Colonel William O. Coleman's 46th Arkansas Infantry (Mounted) all other Arkansas units were assigned to James F. Fagan's Division of Arkansas troops in Sterling Price's Army of Missouri for Price's 1864 Missouri Expedition, so I assumed that the 48th is the designation of one of the Arkansas units assigned to Fagan's Division.

What say you?
