The question was about the fiercest battle. Now this question is pretty ill defined. It doesn't mean the most killed, as in Stalingrad. It you define fiercest as the most killed within a certain period of time then you can somewhat compare using historical statistics but, those get more hazy the further you go back. Also, recorded history is mostly a European history that does not include those Japanese or Chinese battles which are poorly documented. he only answer to the question in an opinion. The only way we can form an opinion is by reading about the battle and using some sort of rule-of-thumb to make the determination. Percentages, as some have mentioned are useless without other considerations. A battle of two will have 50% casualties if one is killed. Where one fights a battle against an enemy with their whole soul, that is the fiercest battle in history.
