Question About Facing After Retreat

[Tom H.]

When you are forced to retreat a hex, can your facing change?

If so, do you or your opponent choose the new facing?

The answer to these questions appears to have definite tactical repercussions.

In any event, it seems like the facing after a retreat can sometimes result in an unnatural alignment.

I couldn't glean anything from the rules to address this situation. I searched the forum a bit, but didn't readily find anything.

Thank you for any insights.
