The Holly Springs Raid Delayed Grant's General Order No. 11 That Expelled Jews from His Department

From Wikipedia.

Van Dorn's raid nearly coincided with U.S. Grant's General Orders No. 11 issued on December 17, 1862.  Thus expelled the Jews as a class from his military district within 24 houirs.  (Van Dorn's raid occurred on December 20.)

Grant believed that Jewish traders violated U.S. Treasury Department cotton trade regulations  which was the reason for the General Order.

Van Dorn's raid disrupted Union communications for weeks.  Additionally, Nathan Bedford Forrest's West Tennessee Raids, starting December 10, destroyed communications along 50 miles of the Mobile & Ohio Railroad behind Grant's front line.

The raid delayed implementation of Grant's orders, saving many Jews from possible expulsion.  It took 11 days for the orders to reach Paducah, Kentucky.  After which, many Jewish leaders appealed to President Lincoln.

At Lincoln's insistence, General-in-Chief of Union armies Henry Halleck ordered Grant to revoke General Order 11.  When Grant ran for president in 1868, this order  proved such an embarrassment that he disavowed it.
