If Gilroen arrives with a large army, we'll either have to waste time or pretend to be Scottish. 😉
If we go straight there, we won't have enough troops to make it (there are either phoenixes or earth elementals).
Running away from the elf is tedious.
By maneuver, I meant capturing the upper city and then the unoccupied capital ("While the cat's away, the mice will play" - J.R.R. Tolkien).
Well, I don't know, when I took two cities and was about to attack the phoenixes, he himself appeared where the elven dragons were, and I had to flee. I managed to reach the capital and defeat him there.
