What was the death toll at the Battle of Shiloh?

the battle of Shiloh was a very bloddy battle. Total casualties -- dead, wounded, or missing -- for the Union Army were 13,047 (1754 dead) and for the Confederate Army, 10,699 (1728 killed).

This total of 23,746 military combat casualties in a two-day battle is greater than the U.S. combat casualties in either the entire War of 1812 (6765) or the Mexican-American War (5885).
