Perseus's Battle Plan
Perseus and Alexander's venue for the battle was right along the banks of the River Diannu, near the estuary where the river met the sea.
It was after all where Lilybee was situated.
The terrain was a piece of pristinely flat land, perfect for the use of heavy cavalry on Alexander's side and the phalanx of Perseus's side.
Personally, Alexander did not like this setup and would have of course preferred much rougher grounds which would more disadvantage the phalangites.
But unfortunately, he was unable to employ that technique here.
Mainly because there was no such terrain nearby.
The southern half of Tibias was in general very flat, devoid of almost any hills.
This made the whole place perfect for agriculture, and indeed on his way, Alexander had seen vast swathes of very fertile land, fields full of wheat, oats, and other produce.
