Ok. Informational post for you and me since you just entered this side.

Shirmish is in L25. Your first skeleton got to N24 with it's first move. In order to get next to me it has to move one more square, to M24.

Your second skeleton then would move to K26 to flank. I believe with your spell range and the skele's move it can still attack, though it misses.

And you are on P22.
