This company was organized at Milton, Santa Rosa County, Florida, and was called Simpson Mounted Rangers in honor of E. E. Simpson of Milton and Bagdad, Florida, who was a member ot the Secession Convention held at Tallahassee, Florida.
The company was equipped and uniformed by some of the citizens of Santa Rosa County, Florida and by the company itself, the citizens equipping those who were not able to equip themselves. The Confederate Government was at no expense whatever in the purchase of arms, accoutrements, horses, uniforms, blankets, etc, etc. The company was armed with double barrelled shot guns, all the guns being cut down to uniform length with slings so as to be hung over the shoulders, and the buck and ball cartridges were used, nearly every man armed with a home made sabre, the sabres were made from old saws of good steel and the scabbard made of sheet iron, sword and scabbard both being manufactured at Bagdad, near Milton.
The company was fully equipped and mustered into service on the 17th day of September, 1861, the mustering officer being J.E. Slaughter one of General Braxton Bragg’s staff. The company at first numbered about seventy five men.

Fifteenth Confederate Cavalry Regiment
The 15th Confederate Cavalry was organized in early 1864 at Mobile, and it was composed of Alabama and Florida companies which had been on coastal defense duties for two or three years. Placed under the command of Col. Henry Maury, it remained in the vicinity of Mobile and Pensacola for most of 1864, except for a period in the fall when it was sent to Louisiana to play a roll in the fight at Tunica. It served successively in Jenifer's, Reynolds', Patton's, McCulloch's, and Clanton's brigades, Maury's army. It was early described as "full, well mounted and well armed", but by December, it was reported as poorly clad and scantily fed." Then in January 1865, its ranks were filled with citizens from Mobile and the surrounding area, armed with miscellaneous weapons but numbering 1200 men. By February, its numbers were reduced to 800, but its companies were almost always on detached duty, watching and checking for an enemy advance against Mobile. In April 1865, it was sent to establish a courier line to Demopolis, but before this was done, the regiment took part in a disastrous fight at Claiborne where it blew up the magazine and evacuated Choctaw Bluff on the 14th of the month. The greater part of the regiment disbanded, and the few who remained were paroled at Demopolis. Col. Henry Maury was disabled by a wound just before the close of the war and the regiment was commanded by Lt. Col. Myers at Claiborne.
