Notes:
Eastern Theater battles are in bold. Western Theater battles are marked with an asterix.
“Casualties” is not just men who died. It includes killed, wounded and captured or missing from both sides. Almost all the casualties from Harpers Ferry consisted of the captured Union garrison and 70% of the casualties from Fort Donelson were of the captured Confederate garrison.

Antietam, also known as Sharpsburg, was one of two single day battles in the costliest 15. It was also the bloodiest single day of the Civil War and in American military history.
