Battle of the Hellespont

The Battle of the Hellespont took place in 321 or 320 BC between the armies of Craterus and Neoptolemus against Eumenes. It was part of the wars between Alexander's successors. Eumenes and Neoptolemus were sent by Perdiccas to prevent Craterus crossing the Hellespont into Asia, but Neoptolemus deserted to join Craterus. Eumenes won the battle, and both Craterus and Neoptolemus were killed.
