That's an interesting find, Ewan. It makes perfect sense that the French would reactivate their naval riverine force to patrol the Rhine (
Forces maritimes du Rhin, disbanded IRL in 1966) during the Twilight War.
A quick Google search suggests that the USA and UK also had Rhine riverine forces for several years after the end of WW2. I was unaware of any of them.
