December 17, 2006 is the 144th anniversary of the worst official act of anti-Semitism in American history.

On that day in 1862, in the midst of the Civil War, Union general Ulysses S. Grant issued his infamous "General Order #11," expelling all Jews "as a class" from his conquered territories within 24 hours. Henry Halleck, the Union general-in-chief, wired Grant in support of his action, saying that neither he nor President Lincoln were opposed "to your expelling traitors and Jew peddlers."
