For Germany and the soviet Union nearly every day between june 1941 and may 1945, in minimum 12 million soldiers, but rather 19 million, so an average of 8450-13400 men for every single day.

I think for sheer casualties, Towton is still the bloodiest, with around 28,000 casualties on both sides. I think Worcester was around 3k dead for the Royalists and I think Preston was a bit less.

Pound for Pound, I think the siege of Basing House and the series of battles surrounding it, was a bloody battle foe the Roundheads, losing 2,000 dead from a force of 7,000 during the first siege.
Was Towton really that high? A War of the Roses battle?

IIRC, overall Royalist casualties at Worcester were around 13,000 (obviously not all dead though).

For France it was August 22, 1914.

During that single day on the Western Front during the First World War, the French Army lost approximately 27,000 men.
Heh, they lost a lot more than even that at Waterloo.


There were 26,000 French killed, wounded and prisoners in Waterloo, and 15,000 further missing. KIA were probably much lower that some WWI actions.

I used to think the Nivelle Offensive was blodiest affair in French history, but the 28,000 KIA incurred during the event happened between 16-25 April 1917.


The date of August 22, 1914 was really a bloodbath for the French Army. According to every source, as Scaeva stated, 27,000 French soldiers perished in that single day in a huge battle from Lorraine, through the Ardennes to Charleroi.

So far, by now this is the ranking with proved numbers:


1. France: 22-08-1914 = 27,000 KIA in the Battle of the Frontiers
2. United Kingdom: 01-07-1916 = 19,240 KIA in the Battle of the Somme
3. USA: 17-11-1862 = 3,654 KIA in the Battle of Antietam

Well, I guess if we're only going by KIA, then yes.

Oh, My God... what a level... to say US Army had 3.000 Killed in Antietam is false...
US Army had more killed D-Day than in Antietam. It is out of question to argument about that... save in this forum, one "intellectual scholar" say Lee, Jackson and Hill were "US Army"...

I'm not talking just about the US Army, I'm talking about nations. For me, the Union and the Confederacy, where two forms of the same nation.

Under the argument that the only valid "nation" and army is the one that won the war and united the country again, we exclude many Civil War battles through the history of the world. So that, casualties to be count in the Chinese Civil War would be just those of Communist China, and not the ones suffered by Nationalist China; in the Spanish Civil War, would be only those of the Nationalist side, and not the Republicans; in Vietnam, only those of NVA and not those of the ARV. I can keep posting examples like this ad nauseam.

In Antietam, 3,654 Americans died in battle.
