As regent, Alexander practices military skills himself and studiously trains the soldiers left to him, making them ready when he puts down a rebellion in Thrace. He is aided by his childhood friend, Lambaros, who knows the local terrain. Upon driving off the rebels, Alexander founds the city of Alexandropolis Maedica and then joins his father against Perinthos. There, he saves his father's life but Philip, ashamed, pretends to have been unconscious and to not remember it, losing some of the loyalty he had earned from Alexander in their shared battle plans.
