Men, before the battle starts I have one important announcement:
With battle at hand I can now tell you that
the Grandmaster of the Knights of St. John has previously agreed to join me as my vassal. Indeed, the reason we are here is to save him! Andronikos does not know this, and thus does not know the danger he is in.
Therefore,
I am ordering you all never to engage the Tagarians without my direct orders. Any regiments found responsible for bloodshed between ourselves and the Tagarians forfeit their share of the loot taken from Andronikos' men! Do I make myself clear?
In other news, the army is to be organized as follows:
Division 1: My Personal Guard (1)
Division 2: The Heavy Infantry (3)
Division 3: The African Mercenaries (3)
Division 4: The Spearmen (5)
Division 5: The Militia (3)
Division 6: The Archers (6)
(OOC: Basically your suggestion, except that I made a seperate regiment out of the Africans and bumped the Archers down to Division 6)
We'll deploy in a strong defensive formation. I believe Andronikos will try to focus all his might against one opponent first, attempting to achieve superiority in one area. This formation shall protect us if he should choose to go after us, and if he decided to focus on the Tagarites then the formation may convince him that we intend to wait out such a battle before sweeping in and eliminating the survivors. This could cause him to commit his forces against the Tagarians, leaving him less able to oppose us.
OOC: The black lines indicate which direction each division is facing. I hope it's clear.
Now then, to battle! When this is all over, only one enemy shall remain!
