Holly Springs, preventing Grant and Sherman from converging on Vicksburg. Grant observed sabotage by civilians who had feigned loyalty and complained: "Guerrillas are hovering around in every direction." On December 29, a Confederate army led by Lieutenant General John C. Pemberton repulsed Sherman's direct approach ascending the bluffs to Vicksburg at Chickasaw Bayou. McClernand reached Sherman's army, assumed command, and independently of Grant led a campaign that captured Confederate Fort Hindman. Contraband fugitive African-American slaves poured into Grant's district, whom he sent north to Cairo, to be integrated into white society as domestic servants in Chicago. However, Lincoln ended this move when Illinois political leaders complained. On his own initiative, Grant set up a pragmatic program and hired a young Presbyterian Chaplain John Eaton to administer slave refuge work camps. Compensated contraband freed slaves would be used to pick cotton that would be shipped north and sent to aid the Union war effort. Lincoln approved and Grant's camp program was successful. Grant also worked freed black labor on the bypass canal and other points on the river, incorporating them into the Union Army and Navy. Grant's war responsibilities included combating an illegal Northern cotton trade and civilian obstruction. Smuggling of cotton was rampant, while the price of cotton skyrocketed. Grant believed the smuggling funded the Confederacy and provided them with military intelligence, while Union soldiers were dying in the fields. He had received numerous dispatches with complaints about Jewish speculators in his district. He also feared the trading corrupted many of his officers who were also eager to make a profit on a bale of cotton, while the majority of those involved in illegal trading was not Jewish. Outraged that gold paid for southern cotton, Grant required two permits, one from the Treasury and one from the Union Army, to purchase cotton. On December 17, 1862, Grant issued a controversial General Order No. 11, expelling "Jews, as a class", from his Union Army military district. The order was fully enforced at Holly Springs (December 17) and Paducah (December 28). Confederate General Van Dorn's raid on Holly Springs (December 20), prevented many Jewish people from potential expulsion. After complaints, Lincoln rescinded the order on January 3, 1863. Grant finally stopped the order within three weeks on January 17. On January 29, 1863, Grant assumed overall command. Eventually, he attempted to advance his army through water-logged terrain to bypass Vicksburg's guns. The
