Flying unit retreat

[Saxon]

Graeme, thanks for clearly expressing the retreat rules, it clarifies the sitution. While I knew that the unit could not retreat to an enemy province, I did not know if they could retreat over enemy provinces to a friendly one.

In the event, the enemy dragon did not get a chance to retreat and was swarmed by hoplites and spiders. I am pleased because there is still a large rump of C'tis remaining and having that dragon loose would have made things more difficult.
