Undaunted by his failure on the 19th and realizing that he had been too hasty, Grant made a more thorough reconnaissance then ordered another assault. Early on the morning of May 22, Union artillery opened fire and for four hours bombarded the city's defenses. At 10:00 the guns fell silent and Union infantry was thrown forward along a three-mile front. Sherman attacked once again down the Graveyard Road, McPherson in the center along the Jackson Road, and McClernand on the south along the Baldwin Ferry Road and astride the Southern Railroad of Mississippi. Flags of all three corps were planted at different points along the exterior slope of Confederate fortifications. McClernand's men even made a short-lived penetration at Railroad Redoubt. But the Federals were again driven back with a loss in excess of 3,000 men.
