Galvanized Tars: Confederate POW's Who Enlisted in the Union Navy, by Terry Foenander.
As the war progressed, and the Union prisoner of war camps continued to expand in numbers, conditions steadily decreased within these facilities. Many of the Confederate prisoners held in these camps could no longer tolerate the close confinement and filthy conditions, and decided to grab the proverbial 'dangling carrot,' and take the Oath of Allegiance. Some of these men were recruited into the service of the Union. Galvanized Yankees was the term used to denote former Confederate prisoners of war who enlisted in the Union Army. Galvanized Tars is the term that I use for those Confederate prisoners who took the Oath and joined the Union Navy and Marine Corps.
Unlike most of the Galvanized Yankees who were sent west to serve against the Indians, thus avoiding contact with their former comrades on the eastern battlefields, it seems that the majority, if not all, of the Galvanized Tars served upon Union Navy vessels, or on-shore facilities, in the eastern theater. Some used the opportunity to desert and return south, perhaps to fight again, but most served their full period of enlistment in the Navy. A small number were even appointed to the ranks of officers within the Navy. Many of these Galvanized Tars were former Confederate Army personnel, but there were some who had previously served in the Confederate States Navy, before their capture and confinement. Indications are that most, if not all, of the enlisting of Confederate prisoners of war into Union Naval service occurred in the final one or two years of the war.
The following article, under the heading of The Enlisted Rebel Prisoners, and dated at Boston, Thursday, February 4, 1864, is reprinted from the New York Times of Friday, February 5, 1864:
The detachment of Rebel prisoners which came here in charge of the Chicago Zouaves, and are now on board the receiving ship Ohio, numbers 208 men. They are from nearly every State in Secessia - some hailing from Georgia, Alabama, Louisiana, Arkansas, and many from Tennessee. The most of them were captured at Missionary Ridge in the last battle between Grant and Bragg. They did not desert, but they say they were willingly made prisoners, as they could have easily escaped had they so desired.
They are very orderly and appear well pleased with their situation - three of them were sent off in the Sacramento, and they have been placed on board the Pequil. More than two thirds of their number are foreigners, and very few are natives of the States which they represented in the Rebel army. According to their story, not one of them is a conscript, most of them having enlisted at the opening of the war for one year, but were afterward forced to enter the service again.
They tell the old story of despondency in all parts of the South, and unless there are better prospects of obtaining independence by the end of the coming May, when the term of the enlistment of the Rebel army expires, the soldiers will refuse to fight longer and lay down their arms; they say there are hundreds of prisoners at Camp Douglas and Rock Island who are ready and would be glad to take the Oath of Allegiance, but they are unwilling to enlist.
Unfortunately no full length study of this particular aspect of the Naval war has ever been undertaken, and because of this we have no idea about the number of Union Navy personnel who had previously served for the Confederacy. Such research would need to cover statistics such as the number who enlisted, their reasons for doing so, and the number of personnel who remained in service. Almost certainly some would have enlisted and then taken the opportunity to desert and return to the Confederacy. If a large number of these Galvanized Tars deserted then the scheme would not have been viable.
Listed below are the names of Galvanized Tars obtained from several sources, as indicated in the references shown at the end of the listings. This is only a preliminary list and more names and data will be added as they come to hand.
