River crossing halts Macedonian expansion

I haven't been able to make it to the club recently, and it will be at least a month before I manage again.  Gordon did, however, take in the forces for a campaign game.  Apparently the defending Persians managed to repeat their performance in the valley of death game we played a while ago with the same foes.  Some useful delaying terrain, including a river, plus significant Persian shooting across the front combined to halt the Macedonian juggernaut.  For the time time being, at least.  When I get back, the next game is a Persian counterattack, which will finish off the current Empire turn quite nicely.
