A number of US Civil War battles were fought on Northern soil. The most significant ones were Gettysburg (Pennsylvania, 1863), South Mountain and Antietam (Maryland, 1862), Perryville (Kentucky, 1862), Wilson's Creek (Missouri, 1861), Buffington Island (Ohio, 1863), Monocacy Junction (Maryland, 1864), Fort Stevens (Washington, DC, 1864) and Falling Waters (Maryland, 1863). Gettysburg and Antietam ended Robert E. Lee's two invasions of the North (South Mountain was fought a few days before Antietam). Perryville ended Braxton Bragg's invasion of Kentucky. Wilson's Creek did much to save Missouri for the Union. Buffington Island put an end to John Hunt Morgan's Ohio Raid. Federals under Lew Wallace (who later wrote the epic novel "Ben Hur") slowed Jubal Early's Confederates who were on their way to Washington. Fort Stevens was a minor battle but it ended Early's invasion of the North. Falling Waters took place during Lee's retreat from Gettysburg.
