Lysimachus Resists, Antigonos Allies
Finding out he was being removed from his post, Lysimachus was enraged, and declared himself the New Hegemon of of Greeks, effectively declaring independence. Soon, Antigonos, getting a similar message, created an entity "The Kingdom of Lydia," and allied with Antigonos. They claimed to be protecting traditions of the Macedonians compared to the "barbarized" Alexander, earning a fair amount of support in Macedon and Greece. Thus the Revolt of the two Satraps occurred.

Crossing into the Euphrates
They planned to march across Anatolia, pass the Northern Euphrates, and threaten the great city of Babylon. They did not find much resistance on the rest of the Anatolian Steppes, so crossed the Northern Euphrates. Local satrap Arkesilas raised a reasonable army of 5000 Macedonian troops, however, found himself outnumbered by Antigonos 25,000. To compensate for this, superior terrain was to be found. Thus the battle of the South Euphrates begun.
