Castle Morgan: The Cahaba Federal Prison

The Cahaba Federal Prison at Cahaba Alabama was unofficially known as "Castle Morgan" after Confederate cavalryman John Hunt Morgan.

The prison was first used as a staging area for the larger prison at Andersonville, Georgia. It was originally intended to house 500 prisoners but as Andersonville became overcrowded it was reestablished as a regular facility. By March 1864 the population had grown to 660 and by the end of the war it was housing over 2,000 persons.

Colonel Sam Jones was commander of the post at Cahaba. He was responsible for the garrison and prison guards. Captain H. A. M. Henderson was responsible for operating the prison. Unlike Colonel Jones, Captain Henderson was much admired by the prisoners for his humane treatment. He was a Methodist minister who later presided at the funeral of President Grant’s mother.

During his service at Cahaba Henderson worked diligently to effect prisoner exchanges and to acquire basic provisions. In November 1864 Henderson sent 100 sick and wounded prisoners to Savannah and 400 to Meridian for exchange. In December he negotiated with federal officials to supply clothing for 2,000 prisoners under a flag of truce.

Opened in June of 1863, the prison was improvised from an uncompleted cotton warehouse owned by Colonel Samuel M. Hill. Colonel Hill started the warehouse construction anticipating the success of the Cahaba Marion Greensboro Railroad. The Confederacy took up the railroad and its assets to complete the more strategic Selma Meridian Railroad to Demopolis.

The brick walled warehouse Measured 193 feet by 116 ft. The roof was completed just over one half of the warehouse building. It was surrounded by a stockade of 2-inch thick planks set 3 ft into the ground with a walkway at the top. Tiers of wooden bunks in the completed roofed section slept 432 men. Water was supplied from a natural spring that ran 200yards in an open ditch through the town and through the building to the water closet and finally into the Alabama River. The water closet could accommodate 4 men.

There was a single fireplace in the building and fires were sometimes built upon the earthen floor of the barracks. Cooking was done by the prisoners on open fires outside the building within the stockade. They were given a ration of cornmeal and bacon that was often rancid.

In February of 1865 the prisoners were shoulder deep in freezing Alabama River floodwaters for 4 days. Finally they were allowed into the nearby woods to collect cordwood to stand on.

Cahaba survivor Private Jesse Hawes was one of few who published memoirs of their experiences. His 1888 publication unfavorable compared the misery of Castle Morgan to that of Andersonville. Louis W. Day in his history of the 101st Ohio Infantry wrote that it was an exceedingly well ran prison. Memoirs of several other inmates testified to the humane treatment.

The earliest mention in the official war records is an inspection report by the prison surgeon Dr. R. H. Whitfield in March 1864. Among his concerns was the intolerable pollution of the open water supply by prison guards and town citizens. The water was than enclosed in pipe. Barrels were buried into the earth floor to form reservoirs.

War department figures indicate a death rate in Northern prisons of 12% and 15.5 % for Southern prisons. At Cahaba it was 5%. The high death rate in Confederate prisons is not surprising when Southern states could hardly feed and supply it troops. The low death rate at Cahaba could have been for humane treatment, but more likely it was because of the transit nature of the prisoners.

Cahaba is now an historic park with only a few vague landmarks to testify of its glorious past. The site of Castle Morgan is hardly more than a square on the site maps. Neighboring Casiste Indian village is now an important archeological site.
