I guess I have to add to french theme:
Heroes of 1812 year Patriotic War - Miloradovich and Uvarov spoken french VERY poorly. But in aristocratic sphere always tried to speak french.
Once at dinner with Aleksander I they sat by both sides of russian general Aleksander L'ajernon, french by nationality, and always chatted between each other.
And after dinner Aleksander I asked L'ajernon what Miloradovich and Uvarov discussed with such enthusiasm.
- I'm sorry, mylord, but I can't understand a word - they spoken french.

After realising that and seing that everyone is in shock he apolagized brfore Catherine, who replied calmly:
-Please, admiral, continue your most interesting story and don't worry,anyway I am not familiar with that naval terms.
