The Iron Bank of Columbus was managed by William H Young, who was a friend of Confederate Sec of the Treasury, Christopher G Memminger.
There are two different tales concerning the Iron Bank of Columbus.
The first claims the gold and silver from the CSA occupied US mint in New Orleans was shipped to the Iron Bank for safe keeping. On Oct 11, 1862, CSA Gen PGT Beauregard removed the gold & silver by force from Young's Iron Bank.
This story is suspect due to the fact that Memminger had the New Orleans gold & silver shipped to CSA Assayer Guirot at Dahlonega, Georgia-it was received June 1862 and crated and shipped on Oct 1,1862 to Augusta, Georgia.
It never arrived.
The second story involves James H Wilson's Raiders attack on Columbus, Georgia, April 16, 1865, 7 days after Lee's surrender. Wilson destroyed and burned anything of use to the Confederacy, and as the story goes, thought that the remaining Confederate treasury was hidden at Young's Iron Bank because of Young's friendship with Memminger.
Between April 12 and April 19, the treasury was shipped from Chester, SC to Marshall's White Hall Plantation in Abbeville, SC, and by May 3,1865 it had made its way to Chennault's Plantation in Washington, Ga, where $250,000 was stolen by armed men, and by May 24, the Union army recovered the rest.
Jefferson Davis's two treasure and baggage wagons made it to David Levy Yulee's Cottonwood Plantation in Archer, Florida, and what was carried by CSA Sec of State Judah P Benjamin, CSA Sec of War John C Breckinridge, and Davis's nephew, CSA Capt John Taylor Wood during their flight through Silver Springs/Ocala ,Florida and out of the country.
