Don't even think about posting the novel in the Mead Hall...It's already done by me.

Byzantines
7.000 professional soldiers?! When?! In 1204 maybe.
They had about 4.000 regular Byzantine soldiers and 3000 latin troops.

They weren't heavy infantry. Even the Varangians dissapeared.
Apart from the Emperor himself, who still had a horse, there was no cavalry.

They were normal militia units. And the mercenaries were sort of medium infantry, with chain mail and swords.

Turks

Bashibuzouks
Anatolians
Janissaries

Bashibuzouks - light armour and curved swords, fanatics
Anatolian Infantry - medium infantry, medium armour, sword
Janissaries - elite infantry, heavy armour, sword and halberd like weapon

Archers - light armour, dagger, composite bow

Sipahis - heavy cavalry

This is what they used, apart from the artillery.
