July 4, 1863, was a glorious day for the Union cause. It saw the surrender of Vicksburg and the retreat of General Lee's Army of Northern Virginia after a crushing defeat at Gettysburg. In interweaving the narratives of these two storied battles, Duane Schultz has presented a compelling blow-by-blow account of what is arguably the most pivotal point of the entire conflict.All the players are brought to life here, whether it is Lincoln agonizing in the telegraph office while he waits for news from Generals Grant and Meade, General Pete Longstreet trying to cajole Lee into revising his plan of attack, or the women of the towns of Vicksburg and Gettysburg coming under fire and tending to the legions of wounded.We see a nation in the midst of its greatest convulsion, and we see that, while the "Glorious Fourth" dashed the greatest hopes of the Confederacy, the war was far from over.
