1862 Battles Transformed Public Expectations
- Shiloh and the Seven Days Battles in 1862 shocked Americans with scale, signaling the war's true lethality and length.
- Gallagher cites ~25,000 casualties at Shiloh and 36,000 at Richmond region engagements as wake-up moments.
Antietam Gave Lincoln The Emancipation Opening
- Antietam (Sharpsburg) was tactically indecisive but strategically crucial: Lee's retreat gave Lincoln the occasion to issue the preliminary Emancipation Proclamation.
- Gallagher stresses McClellan's hesitation despite finding Lee's orders limited the Union's opportunity.
Vicksburg And Gettysburg Arrived Together
- Vicksburg's fall on July 4, 1863 cut Confederate control of the Mississippi and, paired with Gettysburg, marked a strategic shift favoring the Union.
- Gallagher calls Grant's Vicksburg campaign one of U.S. military history's most impressive feats.
