What Was the Bloodiest Battle in American History?

The American Civil War remains one of the bloodiest conflicts in human history. Over half a million soldiers were killed during the four-year conflict, with many more wounded and missing. However, one battle stands out as the deadliest of them all – the Battle of Gettysburg.

The Battle of Gettysburg

The Battle of Gettysburg took place over three days from July 1 to July 3, 1863. It was fought between the Confederate Army of Northern Virginia, led by General Robert E. Lee, and the Union Army of the Potomac, commanded by General George G. Meade.

Day One

On the first day of the battle, Confederate forces attacked Union troops on the outskirts of Gettysburg. The fighting was intense, with both sides suffering heavy casualties. By the end of the day, Confederates had gained ground but failed to capture key strategic points.

Day Two

The second day saw some of the fiercest fighting in American history. Confederate forces launched multiple attacks against Union positions on Cemetery Hill and Little Round Top. The Union army managed to hold their ground after a brutal fight that lasted for hours.

Day Three

On the third and final day, Confederate troops launched a massive assault on Cemetery Ridge – known as Pickett’s Charge – that resulted in staggering losses for both sides.

The Aftermath:
By the end of three days, approximately 51,000 soldiers were dead, wounded or missing at Gettysburg – this included approximately 28% – or nearly one-third – of Lee’s army and about 23% – or more than one-fifth – of Meade’s army.

  • The total number killed in action: 7,058.
  • The number of wounded in action: 33,264
  • The number of missing in action: 10,790.

The Importance of Gettysburg:
The Battle of Gettysburg was a turning point in the Civil War. It marked the first major defeat for Confederate forces, and it ended Lee’s invasion of the North. The battle also boosted Union morale and gave President Abraham Lincoln an opportunity to deliver his famous Gettysburg Address.


In conclusion, the Battle of Gettysburg was the bloodiest battle in American history. It was fought over three days and resulted in staggering losses for both sides. However, it also marked a turning point in the Civil War and had long-lasting effects on American society.
