Ipsus (Wars of Alexander's Successors).

Fought B.C. 302, between the Syrians, 32,000 strong, under Seleucus, and the Macedonians, 30,000 in number, under Antigonus. Seleucus utterly routed the Macedonians, Antigonus being among the slain. Demetrius Poliorcetes, who now took command, only succeeded in rallying 8,000 men, after fleeing for 200 miles.
