Hello, Elle!
The Fleet has gone underground, yes.
Won't be much room under London with all these rivers and Tube tunnels!
The problem with Americans/Indians is that Columbus was bad at geography or seamanship, and was not where he thought he was!
Possibly where Pigale was brought up the term Hindu was used.
I never heard it.
I am certain you have cracked Quizmad's puzzle.
I looked at that clue for ages, thinking "where, in the name of the wee man, is Elle's anagram?"
In fairness, I was looking for an 8 letter one, after the "e"'s had gone.
I am not saying Quizmad has posted wrongly, but it is no rare thing for a clue to be wrong. Words missing, wrong letter count etc. Could be an error in the quiz.
I think your answer was super!
Needless to say, has anyone ever heard of the place?!!
