Did napoleon have friends?

He considered very few people friends. Maybe even nobody.

Talleyrand considered himself a loyal servant (he switched sides right away when Louis came back)

Even his family ( Caroline and Joachim Murat) turned against him at some point,

when they thought he didn't come back from a mission.

Abbe Force tried to help him escape from St. Helena. Napoleon sometimes refers to him as a friend.

You could call Betsy Balcombe and her family his friends. They weren't interested in his political power because by the time they met him ( in St Helena) he lost all of it.
