Really obscure question that I have no idea how to research: In the antebellum era circa 1825-1855, did Great Britain maintain any sort of legation or consulate in any of the major southern Atlantic ports from which cotton was shipped, especially Charleston South Carolina? Or was the embassy in Washington unique?
Yes, to protect their commercial interests Britain had consuls and vice-consuls located in several Southern port cities including Charleston, Savannah, Mobile, and New Orleans,
