Pyrrhus had the bulk of the army of Epirus with him, probably 20,000-25,000 men, while Pantauchus commanded but a detachment of Demetrius' army consisting of around 11,000 men.
The fighting was heavy, and according to the sources Pantauchus and Pyrrhus sought out one another. Pantauchus challenged Pyrrhus to individual combat, Pyrrhus accepted. After hurling spears at each other they fought it out with swords. Pyrrhus was wounded, but in return wounded his opponent twice, in the thigh and in the neck. Pantauchus' bodyguards had to carry him away.
Emboldened by their king's victory the Epirots resumed their attack and broke Pantauchus' army, and took 5,000 prisoners. The army then honoured Pyrrhus by bestowing the surname of 'Eagle' upon him (way before khabibi). Demetrius, upon hearing of Pyrrhus' victory, marched back to Macedon.
Pyrrhus released his prisoners and marched back to Epirus for body and mind.
