The rest of your statement is so pathetically silly I don't even know where to start. Black participation in the Union army wasn't even permitted until 1863. At the end of the war it was less than 10% of the Union army and blacks were not primarily serving in combat units. The Irish constituted an even smaller percentage -- just over 7% by most estimates. The highest I've ever seen was 7.5%.
While it's incredible the history you Lost Causers are ignorant of, it's nothing compared to what you think you know that's simply wrong.
The New York City draft riots (July 13 to July 16, 1863; known at the time as Draft Week[2]) were violent disturbances in New York City that were the culmination of working-class discontent with new laws passed by Congress that year to draft men to fight in the ongoing American Civil War. The riots were the largest civil insurrection in American history.[3]
President Abraham Lincoln diverted several regiments of militia and volunteer troops from following up after the Battle of Gettysburg to control the city. The rioters were overwhelmingly working-class men, primarily ethnic Irish, resenting particularly that wealthier men, who could afford to pay a $300 commutation fee to hire a substitute, were spared the draft.[4][5]
So Lincoln, besides being a butcher was a liar. Ok. I can go with that.
One of cva’s routine contentions is something along the lines that the north imported or drafted off the boats foreigners to fight against the rebels. Thus his emphasis on “Foreign Soldiers”.
I have yet to see any evidence of that. What cva provides is evidence that immigrants were willing - or compelled - to fight. This link: http://www.upa.pdx.edu/IMS/currentprojects/TAHv3/Content/PDFs/Immigrant_Soldiers_Civil_War.pdf puts the Irish immigrant participation at 9.1%. I guess somehow he feeeeeeeeeeels that this proves his point (whatever that is).
But here is where it becomes interesting. The same documentation that shows the diversity of northern soldiers also shows that the confeds were pretty much a white-bread operation with only about 9% foreign born. Source: http://www.upa.pdx.edu/IMS/currentprojects/TAHv3/Content/PDFs/Immigrant_Soldiers_Civil_War.pdf
So the interesting part comes when the revisionist lost causers (but I repeat myself) attempt to portray themselves as champions of diversity. Read this document and notice how that same 9% is presented to look like a rainbow of diversity: http://www.florida-scv.org/Camp1316/Minorities%20in%20the%20Confederate%20Army.pdf
I guess it isn’t so much the truth as it is the telling ;-)
To save the Union from what?
