Flying unit retreat

[Saxon]

Hmm, I think he must have routed. It is C'tis and they do not seem that sacred. The hall of fame is dominated by my Ermor killing priests and I do not remember his magic paths, so I may never know.

Let me re-phrase my main quesion. Can a retreating flying unit with a lot of movement retreat over the encircling provinces? I would prefer to kill it outright, but if he does rout, would he still be eliminated? I ended up baby sitting last night, so I did not get to find out the hard way.
