I'm flushing away your poo and your pee?
Although it may sound so, that is not me!
When people were fighting hard near to me,
It was not about who gets first to pee.
The loser, who came from an island before,
Was sent to another one later therefore.
One winner came from an island as well.
What place could I be? You sure know me well!
The answer is
WATERLOO.

The name sounds like water being flushed down the loo, flushing away poo and pee.
When people were fighting hard near to me,
It was not about who gets first to pee.
The Battle of Waterloo was about more important things than pissing.
The loser, who came from an island before,
Napoleon came from Corsica ...
Was sent to another one later therefore.
... and was exiled to Saint Helena after losing the Battle of Waterloo.
One winner came from an island as well.
Wellington, one of the victorious generals at Waterloo, was from Britain.
What place could I be? You sure know me well!
WATERLOO.
