The rampantly successful Ptolemaics decide to try to remove their Seleucid rivals entirely from the map, invading what's left of the Seleucid "Empire" in Mesopotamia. They encounter the defenders in an area of rolling hills. All of the following photos are taken from behind the Seleucid army, which I ran all by myself for a change:
Overall, it went in my favour. My left worked well, and the right exceeded all expectations. The centre held just long enough for the Argyraspides to come in and destroy the enemy phalanx. Quite a comprehensive win in the end. Next up: the Seleucids have to turn around and face an invasion from the other direction as the Bactrian Greeks decide to try their hand.
