Largely recruited from the Odrysian tribe, the Thracian cavalry also acted as scouts on the march.
In battle, they performed much the same function as the Prodromoi and Paeonians, except they guarded the flank of the Thessalian cavalry on the left wing of the army.
The Thracians deployed in their ancestral wedge formations and were armed with javelins and swords.
At Gaugamela, the Thracians fielded four ilai and were about 500 strong.
