ANy experts on medallions?

[NoName]

Good evening everyone!
I am on a group on facebook and someone was asking about this medallion!
I did some research on the internet myself but without any luck!
It seems to me like it is Napoleon on a horse and there are some engravements tha I cannot read!
Any help would be appreciated!
Thanks
