Source: The Civil War Trust - "Maybe as much as a quarter of the Union Army was made up of foreigners—men who had not been born in America. Of these, the largest group was the Germans, followed by the Irish, Canadians, and English. Other nationalities represented in the army included Scandinavians, Swiss, French, Italians, Mexicans, and Poles. Often, regiments would be formed consisting entirely of men from one of these countries. The polyglot nature of the Northern forces could sometimes create confusion when officers barked orders in several languages."

Are any of the missing countries listed above? I had also wondered whether any Turks drifted our way after the Crimean War?
