Battle of Orkynia

[5] One day Antigonus drew up his phalanx twice as long as usual, hereby tricked his opponent into thinking he had twice as much infantry as he in fact had, this was combined with the treachery of Apollonides' cavalry.

There were thus three elements in Antigonus's battle tactics, and the result was a brilliant victory, in which his smaller army slew about 8,000 of the enemy[6] and most of the rest went over to him.

[7] Eumenes escaped with a substantial body of troops, he captured and killed the traitor Apollonides, evaded the pursuit of Antigonus's forces, and doubled back to the battlefield, where he buried his dead.

Eventually Antigonus caught up with Eumenes, who was forced to take refuge in a stronghold called Nora with his closest followers, some 600–700 in number.

Antigonus left the siege of Nora to a subordinate and marched with the bulk of his army to deal with the remaining Perdiccans: Alketas, Polemon, Dokimos and Attalos.
