Right, but if I get into the war itself, would need a whole new list of "indisputable truths." ;-)
According to this site, of the 2.2 million total Union soldiers, about half were native-born whites Americans.
About half a million were Germans.
Over 200,000 each were African-Americans (half free, half escaped slaves) and Irish.
The balance of nearly 300,000 included Dutch, Canadians, Brits, French, Scandinavian, Italians, Jews, Polish and Native Americans.
Among all these were a total of 450,000 Union troops from Southern & Border States including 150,000 Southern blacks, 200,000 troops from Border States (Missouri, Kentucky, Maryland) and 100,000 from the 11 Confederate states.
The largest actual Confederate state contribution to Union forces came from Eastern Tennessee.
By contrast, the Confederate Army totaled maybe 1.5 million, of whom over 90% were native born whites.
Virtually no northern state citizens served in the Confederate Army.
MD graveyards are full of Confederate Veterans. Missouri supplied way more than 200,000 troops to the PACS.
