Price's Missouri Raid,

The 45th Arkansas Infantry (Mounted) (1864–1865) was a Confederate Army Mounted Infantry regiment during the American Civil War. While authorized by the State Military Board as an infantry regiment, the unit was mounted for Price's Missouri Expedition and was officially designated as mounted infantry. Due to its mounted status, the unit is sometimes referred to as the 45th Arkansas Cavalry when a numerical designation is used. The unit is most often referred to as either Baber's Arkansas Cavalry Regiment or Clark's Arkansas Cavalry Regiment, after its two commanders. After the war many former members referred to the regiment as "Shaver's Cavalry" because of the large number of officers and men who had previously served in Colonel R. G. Shaver's 7th Arkansas Infantry Regiment and 38th Arkansas Infantry Regiment, but Colonel Shaver was never actually associated with the unit.

In May 1864, General Joseph O. Shelby occupied Northeast Arkansas, well behind Union Army lines. In early June 1864, General Shelby commissioned Colonel Thomas Hamilton McCray, among others, to begin raising regiments in Northeast Arkansas. By June 13, Shelby reported to General Sterling Price that McCray's efforts were bearing fruit.

The work of recruiting goes bravely on. Colonel McCray will have a brigade and Dobbin, Coffee, Freeman and Coleman will have regiments.

Colonel McCray's efforts led to the recruitment of at least three regiments, the 45th, 46th and 47th Arkansas Infantry Regiments. These 40-series regiments consisted mostly of conscripts, and absentees from existing units, organized around a small cadre of veterans detailed from infantry regiments, which were expected to be idle during the fall and winter of 1864.

The decreasing availability of fodder for horses in 1864 led the Confederate Trans-Mississippi Department to issue an order proscribing the raising of additional mounted regiments in Arkansas. However, when General Sterling Price received authorization to conduct a campaign in Missouri that fall, several of the new regiments were mounted in order to accompany him. As a result, the 44th, 45th, 46th, 47th, and 48th were officially mounted infantry regiments instead of cavalry regiments. They were rarely referred to in contemporary reports and orders by numerical designation. Price referred to them as McGehee's Cavalry, Crabtree's Cavalry, etc., which eventually resulted in their later being referred to as 44th Cavalry, 46th Cavalry, etc.
