This move against the Antigonid right flank probably involved detaching cavalry from the allies own right wing, including Seleucus's horse-archers, who could rain down missiles on the immobile phalanx. The morale of the troops appears to have collapsed, and it seems that some of the heavy infantry either defected to the allied side or otherwise fled. Antigonus, stationed in the centre, tried to rally his men, hoping for Demetrius's return. However, he was gradually surrounded by allied infantry and eventually killed by several javelins thrown by allied skirmishers. With the death of its commander, the Antigonid battle-line dissolved, and the battle effectively ended.
