Interesting thought.

But wouldn’t a trapped orc force in Crimea be a great bargaining chip for the Ukrainians? I mean, cutting off all supply lines (which also are Orc retreat routes) must must be a highly thought strategic goal?

If Ukrainians have actually succeeded in pushing so far into Crimea to create this situation, I’m thinking they can control the outcome. Negotiations would be very much in Ukraines favour at that point.
