What was the bloodiest day in American history? In other words, on what day did more Americans get killed outright than on any other day?
September 11, 2001 - Terrorist Attacks
Official Count of victims (Source: Washington Times, 5/31/02)
New York: 2,823 (those killed in the World Trade Center and aboard the two jetliners)

Antietam “wins.”
(Especially if you count the missing and the wounded who later died.)
