Copratus, The (Wars of Alexander's Successors).

Fought B.C. 316, between the Macedonians under Antigonus, and the Asiatics under Eumenes. Each army was about 30,000 strong, and Eumenes fell upon the Macedonians as they were crossing the Copratus, and signally defeated them, though Antigonus was able to retreat in good order.
