I don't think I've come across a French song about being defeated by Britain, either. Hardly surprising. On the whole, countries tend to focus on things they feel proud of.

Having said that, Paul Jones got good coverage in British tradition; he was an expatriate Scot, though, so I dare say it wasn't quite the same thing. As a rule, historically, people only make songs about being defeated if (a) they don't really mind or (b) they feel bitterly resentful about it.
