摘要:July Fourth, in my view, marks the 150th anniversary ofthe climax of the Civil War. On that day in 1863, GENRobert E. Lee retreated from Gettysburg, Pa., with his de-feated Army of Northern Virginia after a gigantic three-daybattle with the Army of the Potomac, commanded by MGGeorge G. Meade. That same day, half a continent away, thefortress city of Vicksburg, Miss., capitulated to MG UlyssesS. Grant's Army of the Tennessee. In my you th, I oftenheard Pickett's Charge at Gettysbu rg referred to as "thehigh tide of the Confederacy," and a glance at a map revealsthe strategic wisdom of a Mississippi River that "flowedunvexed to the sea." Elsewhere in this issue of ARMY, my colleagues, ColonelsCole Kingseed and Kevin Farrell, examine Gettysburg inmore detail and flag up tactical and operational issues thathave excited controversy since the battle ended. Here, Ihope to put Vicksburg and Gettysburg in a strategic contextand underscore the importance of July 4, 1863, as a pivotalpoint in American history
