Stones River (Murfreesboro) - Dec. '62-Jan '63.
The US Civil War with about 213 thousand military dead ranks only slightly behind WWII at 291 thousand in deaths. The Confederates and the Yankees were both Americans and medical care available had advanced greatly between these conflicts. WWI, Korea and Vietnam combined don't reach that level of carnage.

No. The battle had no clear winner.
it was clear that no one won the battle and was the bloodiest one day battle in American history because 23,000 casualties and 4,000 dead
Because there were many battles during the war, going by the saying: "We've won the battle, but not the war," both British North America (BNA) (Canada) and the Americans won battles, but since there was no major battle with a definite winner, and only many small battles which they had their share of winning, there was no clear winner.
It became clear that the war would last for a long time.
The Battle of Antietam was not a clear victory for neither the Confederate nor the Union armies.

There was not a clear winner on Day One. One could argue a Confederate victory, but the Federal forces did seize the high ground and did not relinquish it. That proved to be the deciding factor in the battle.
After the Japanese surrendered it was clear that the US was the winner.
