Retreat in PzC Smolensk '41

[Mr Grumpy]

It just so happens that in a F14 game Rick and myself are playing my cavalry retreated into a hex they could not escape from two turns in a row, on both occasions there was a perfectly safe route to take.

So other than not retreating into a hex that would lead to an overstack (when another hex is available) i think the whole thing is random.
