The save files for this game, the .map file and the .tga or .rgb image file.

Only the save game files are really needed. The .map is inside the ftherlnd and .trn files, the .tga/.rgb takes a dummy graphics file with the same name, too.

I have seen things like this from time to time, but usually it's part of an army, not the full thing. Just speculating, but i think it has to do with screwyness associated with routing to the "garrison box" where unattached troops live in province.
