re: Larry David discovers he had slave owning and Confederate ancestors

Considering the fact that General Grant issued is infamous Order Number 11 it isn't hard to see why a large number of Jews picked up arms for the confederacy.

General Order Number 11 said:

"1. The Jews, as a class, violating every regulation of trade established by the Treasury Department, and also Department orders, are hereby expelled from the Department. Within twenty-four hours from the receipt of this order by Post Commanders, they will see that all of this class of people are furnished with passes and required to leave, and any one returning after such notification, will be arrested and held in confinement until an opportunity occurs of sending them out as prisoners unless furnished with permits from these Head Quarters. No permits will be given these people to visit Head Quarters for the purpose of making personal application for trade permits. BY ORDER OF MAJ. GEN. U.S. GRANT"
