When General Grant Expelled the Jews is new from historian Jonathan D. Sarna (and Shocken books). From Harold Holzer’s review at The Washington Post:
. . . no historian has been able to fully understand — much less justify — why, on Dec. 17, 1862, Grant issued his notorious General Orders No. 11 deporting Jewish citizens. “The Jews, as a class violating every regulation of trade,” went the chilling text, “. . . are hereby expelled from [his command in the West] within twenty-four hours.” Those returning would be “held in confinement until an opportunity occurs of sending them out as prisoners.” Just two weeks before Abraham Lincoln was scheduled to extend freedom to one minority group with the Emancipation Proclamation, his most promising general thus initiated a virtual pogrom against another.
In the end, as the gifted and resourceful historian Jonathan D. Sarna points out in this compelling page-turner, General Orders No. 11 uprooted fewer than 100 Jews. But for a few weeks, he suggests, it terrorized and infuriated the Union’s entire Jewish population. It also inspired one of the community’s first effective lobbying campaigns. Jewish newspapers compared Grant to Haman, the infamous vizier of Persia in the Book of Esther. A delegation of Jewish leaders traveled to the White House to protest directly to the president, who quickly but quietly had the order revoked, eager to right a wrong but reluctant to humiliate a valuable military commander. As Lincoln carefully put it, “I do not like to hear a class or nationality condemned on account of a few sinners.” He never mentioned the episode publicly.
