What was the largest battle ever fought?

Answer 1

There exists a problem in defining a "battle", for the line between "battle", "siege", and "campaign" is a blurry, fuzzy one.

Indeed, the longer a "battle" goes, the better change is gets called a "siege" or broken up into smaller battles grouped together as a "campaign".

In ancient times, a battle generally could not last more than a couple of days - sufficient supplies were not available, and military strategy didn't encompass the idea of long-term combat. Sieges were generally distinct from battles, in that the siege was usually an occupation around a fixed geographic point, often with little actual combat.

In modern times, industrialization and technology have led us to "continuous combat" - that is, actual, significant fighting occurring throughout the day and night (though, not at the same time in all sections of the conflict), continuing on for weeks or months.

There is no real answer to your question, as it depends on arbitrary lines being drawn between a siege, a campaign, and a battle.
