What year did Napoleon lose at Waterloo?

originally imprisoned on Elba. He escaped raised an army was defeated again at Waterloo exiled to at Helena in S Atlantic he died in1819

and his final exile was on a remote island in the south atlantic ocean

The description makes it appear that the Prussia army was completely routed and had nothing more to do with Napoleon's defeat. Even though I am of English heritage I object to this. While Wellington's army held and severely damaged Napoleon's forces at Waterloo, it was the timely arrival of Blucher's troops that shook off the pursuit and circled back to attack that turned a probable draw into a crushing defeat.

one year difference?!
