Gary Gallagher, a historian, discusses the Vicksburg and Gettysburg campaigns of 1863. He emphasizes that Vicksburg, not Gettysburg, was the turning point of the Civil War. He describes Grant's bold campaign, crossing the Mississippi and besieging Vicksburg, which surrendered on July 4, 1863, while Lee retreated from Gettysburg. Gallagher details Lee's decision to invade Pennsylvania, his army's strength of 75,000, and the role of Jeb Stuart's cavalry failure in leading to the three-day battle at Gettysburg. He argues that Lee's aggressiveness caused his defeat, as he attacked rather than adopting a defensive posture after initial success. Gallagher notes Lee's losses, including a third of his army and a third of his generals, and his subsequent retreat. He contrasts this with Grant's capture of an entire Confederate army at Vicksburg, which he argues made it more significant. Gallagher also covers Lincoln's disappointment that Meade let Lee escape, and how Grant's subsequent victories led to his appointment as general-in-chief.
