Here is Alexander and his Bucephalus ahead of his mounted companions.
The Thessalian cavalry.
Agrianians light infantry.
The full Macedonian Phalanx.
The tactic at Gaugamela: here goes Alexander on the right ahead of his Companions trying to spread the Persian cavalry further to the right in order to swiftly change direction and attack Darius on the center.
The figures are Hat and Zvezda. There are also some old Atlantic greeks with new heads mostly that were recruited to the rear ranks of the Pezhetairoi.
Still the Greek hoplites and the Thracians to do.
