Which battle of the American Civil War had the most casualties?

We lost 55k in Vietnam and to think 51k in 3 days at Gettysburg is an amazing loss of life. I live close to Gettysburg and if you never have visited, put it on your bucket list. It's a Holy place which salutes both sides. It's an amazing place and prepare to spend an entire day. Well worth it

A point of interest,the Confederates chose Gettysburg because there was a shoe factory there. Many of the Confederates were fighting with worn-out shoes or barefoot

Always has been very sad for me: Brother against brother. Americans vs. Americans. An account that should be embedded in our hearts. "Those who cannot remember the past are condemned to repeat it." (George Santayana) Whenever a voice or fist in raised in anger to another human being, please read 1John 4:21: "Whoever loves God must also love his brother." World wars killed many people, civil wars kills the soul of our nation.

With the over 50K people lost in Vietnam over a very long period of time, this number of those lost is staggering to imagine, in just three days! What a waste of life. I'm glad slavery was abolished, but to the Confederate side defending that economic way of life and wealth, what a huge meaningless loss of life for something so wrong!

I've been there and it's an amazing place. It has a special solemnity about it. Visiting there was an awesome experience.

Antietam was one day but Gettysburg lasted three so Antietam was the bloodiest DAY but Gettysburg has the dubious honor of being the bloodiest battle. I lived within an easy drive to both places. Very beautiful sites until you contemplate what happened there in the past. May all the deceased find peace

So sad to lose so many heroes!

The battle of Antienam had more casualties than Gettysburgh

Jaime Irizarry, leave God out of it

I clicked on Gettysburg. How is my correct answer wrong?

this was a good question

So sad.

simmingerp, could you tell the full truth

Been there a few times and must agree! Visit the electric map first, then explore the battle field, especially Devils Den!marleyventures,

ronbt, Gettysburg had twice the amount that Antietam did.

swestmark, Thank you for mentioning that, not many know that horrible truth.

linda ergo, The North had slavery too. Blacks had slaves as well. Whites were enslaved too. It was not a war about slavery. Native Americans had slaves and were enslaved. School did not teach the full story.

You probably we’re being watched.

I've visited Gettysburg several times. There is an aura of sadness just by being there. It's a beautiful place though!
