Zeno's plan was to have the two Theoderics attack each other. He sent the Amal against Strabo, who supported the revolt of Marcianus, with the promise of a huge Roman force as reinforcement (478). When Theoderic the Amal arrived through the mountains at Mount Soundis, he did not find the Roman reinforcement army he expected, but instead Theodoric Strabo's army, in a strongly fortified camp. The two Theoderics agreed to put forward a joint request to the Emperor, in order to extend to the south the settlement territory of the Ostrogoths in Moesia.
