We ranked these battles based on the total military casualties, including killed, missing, captured, or wounded. We included supplementary information regarding total casualties on the Axis and Allied sides, as well as the troops and military assets present on both sides. We also included the start date on which these battles took place. Some supplementary information was obtained from various other military and historical sources.
