Existing comment: 1862:
As casualties mounted in 1862, Americans realized the war would be neither short nor easy. Both sides mobilized their forces for a protracted campaign marked by increasingly bloody clashes. In early April, more Americans died in combat during the two-day Battle of Shiloh than in all previous American wars combined. The Battle of Antietam on September 17, 1862, became the single bloodiest day in American history with 23,000 dead, wounded, and missing.
