"Sergeant-Major Abraham Cohn, one of the 9,000 Jews who fought for the Union (some 2,000 Jews fought for the South),..." [RMC Mark S. Starin, USNR (Ret.), Post 100, Jewish War Veterans of the USA, Sergeant-Major Abraham Cohn: Jewish-American Civil War Hero, jewish-history.com . http://www.jewish-history.com/sergeant_cohn.html)"
During the civil war there were 150,000 Jews in both the north and south, of that population, only ten percent, or 15,000 resided in the confederacy, versus 135,000 in the north. In the south Jews enlisted overwhelmingly to fight for their country, not so in the north, there they were for the most part conscripted. (read drafted)
