The Battle of Gettysburg took place in and around Gettysburg, Pennsylvania, from July 1-3, 1863, during the American Civil War. This pivotal clash between Union forces under Maj. Gen. George Meade and Confederate troops led by Gen. Robert E. Lee marked a turning point, with over 51,000 casualties across both sides.

Battlefield Location

The core fighting spanned a roughly 10-mile area within Adams County, Pennsylvania, near the Maryland border in the Gettysburg-Newark Basin of the Pennsylvania Piedmont. Key ridges like McPherson's, Herr's, and Seminary Ridge on the west side of town saw initial clashes, while the Union "fishhook" line extended from Culp's Hill southeast of Gettysburg, through Cemetery Hill, along Cemetery Ridge, and to Little Round Top. The battlefield remains preserved today as Gettysburg National Military Park, drawing millions of visitors annually for tours and reenactments.

Key Phases and Terrain

  • Day 1 (July 1): Skirmishes began west of town at ridges like Knoxlyn and McPherson's, pushing Union forces back through Gettysburg to Cemetery Hill.
  • Day 2 (July 2): Intense action at Little Round Top, Devil's Den, Wheatfield, and Peach Orchard along the southern flank.
  • Day 3 (July 3): Famous Pickett's Charge targeted the Union center on Cemetery Ridge, leading to Confederate retreat.

The terrain—rolling hills, orchards, and rocky outcrops—shaped tactics, with high ground proving decisive for Union defenses.

Historical Significance

Often called the war's "High Water Mark" for the Confederacy, the Union victory halted Lee's northern invasion and boosted Northern morale, paving the way for Lincoln's Gettysburg Address four months later at the Soldiers' National Cemetery. Casualties made it the bloodiest battle in American history, with modern analyses highlighting brutal conditions like soft-lead bullets and field medicine horrors.
