Antigonus, having a superiority in cavalry, resolved to mass his heavy cavalry and most of his elephants and light infantry on his right and strike against Eumenes's left flank, while refusing his center (infantry) and left (light horse). Antigonus and his son Demetrius commanded the heavy cavalry themselves. Eumenes, having seen Antigonus' deployment, placed himself and his best cavalry opposite Antigonus' heavy cavalry along with his own elephants and light infantry. He intended to hold Antigonus's charge while using his elite Argyraspides (the Silver Shields) phalanx to win in the center. The Argyraspides were a unit of veterans who had fought under Philip and then Alexander. Despite the fact that these battle-hardened veterans were old enough to be their opponents' grandfathers, they were still highly respected and thought to be invincible in combat.
